arduino mega (2560) + ethernet shield(Wiz5500) @ bascom 2.0.

Hi bascom colleagues,

....recently i came in contact with arduino "ready to use" modules , previous i was used to design myself hardware by pcb and atmega chips.
the target is, to realize a small webserver with this arduino mega and an arduino ethernet shield 2, which contains the Wiz5500 chip.

after many many hours of troubleshooting, reading and also trying all relevant posts in bascom and arduino forums, which often are contradictionary statements,
i never have successful established this hardware combination.

regarding bascom, i used the wiz5200 lib..... have dealt the hardware in various configs as in forums discussed, but none of these variations has worked.

in general, it is alway possible to download and the devices run itself, the megaboard always runs and the ethernet shield acts ( led indication ) on pings,
( but never the ping was successful responsed...) typical message is : "antwort von 10.100.10.1: Zielhost nicht erreichbar" ( 10.100.10.1 is my PC IP, may be unusual but
necessary because of other industrial ethernet based test components... ) the arduino IP i have set to be in same range of adress and submask....

i checked the 6-pole SPI socket of the ethernet shield and the of the arduino mega and as literature says, there will be no conflict of using the ISP for programming the Arduino mega
by Bascom+STK500 and using the SPI as chain between ethernet shield and Arduino mega. But where is the broken part of that ensemble? Library and Pin enumeration problem? I do not know...

so.. the two units till do never walk together, even simply added via connector or, with separate spi wires and ports lowered as in forums often described. I stuck here...
with arduino IDE, i have played only one two examples, because (sorry..it may not bad but i do not prefer that..) i do not like the rudimentary IDE and the language as well.
As a feeling for me it ist a backstep of level comparing to bascom im my view.

after all fiddling around and hair-stand-up experience Smile

, my simple question is: does anybody (hopefully) of you have successful run an arduino mega with ethernet2 shield on bascom?
If yes, any hints how to make it, are highly appreciated.

thanks a lot for any comment, advice or lightening the way i should proceed...

i think the samples folder contains samples using arduino hardware.
using w3100,w5100,w5200,w5300 and w5500 chips i never had a problem. i also made a converter board for the wiz810mj module.

using some of the tcp shields i did had problems. for example because of a buffer that had to be switched. or because of bad contacts in the headers.
i found arduino hardware nice for proto but not for production.
There is also a lot of variation between the arduino boards and the shields.

I advise to start very simple. Just pick a simple sample from bascom and get the PING working.
I do not know if w5500 has echo enabled by default (some wiz chips have the option to turn off ping).

post the circuit of the shield you want to use.

for w5500 an init like this is required:
Config Tcpip = Noint , Mac = 12.128.12.34.56.78 , Ip = 192.168.1.88 , Submask = 255.255.255.0 , Gateway = 192.168.1.1 , Localport = 1000 , Chip = W5500 , Spi = Spie , Cs = Porte.4
Print "Init Done"

The gateway is important. and the submask too.

while a web server is relatively simple, you should have the ping going first.

- this stuff i work with and how : ----------------------------------------------------------------------------------
used Bascom Version: 2.0.7.8.001
used Hardware: ArduinoMega 2560 PCB Revision V3E
Arduino Ethernetshield2, PCB Revision ETH11 V2

used programming method: STK500 and ISP header of arduino board / no bootloader
------------------------------------------------------------------------------------------------------------

Hi Marc, thank you for fast response, i am going to workout now step by step....

from the Bascom examples ping_WS5300.bas i simply derived the code and changed the config TCPIP:

Config Tcpip = Noint , Mac = 12.128.12.34.56.78 , Ip = 192.168.1.88 , Submask = 255.255.255.0 , Gateway = 192.168.1.1 , Localport = 1000 , Chip = W5500 , Spi = Spie , Cs = Porte.4

compiler complaints "Invalid parameter for CONFIG parameter or Value [WS5500] in C:\\path\ping_ardumega2560_ethernetshiled2_V0.1.bas"
i checked then updates to bascom 2.0.7.9 ( having the valid lic file for 2.0.7.9 in directory ) but update wizard found nothing to do.

so whats the reason why compiler complains about the W5500?

add: attached the schematic of the used arduino ethernet shield

for w5500 you should update. download the full setup from register.mcselec.com (see help topic move to new pc)

the circuit : there is an sd card intreface on it. so you use 2 SS signals.
Just make sure you use the correct spi signal for the w5500. which means you must measure between the micro port pin you use as SS and the w5500 IO10*/SS to see if they match/are connected.

here is a sample for w5500 and xmega. you need to change the spi for normal xmega. but you can grab that from a w5100 sample.

Hello uhrmacher
You can find working webservers in the blog section that I have written
you should only need to change the config for the W5500 instead of the W5100

Hello, good morning Smile

@marc - my email is now updated, sorry for leaving it "old"

-> i have updated successful to 2.0.8.0 and retried to compile with the "chip = W5500" in line Config TCPIP but this option will still be denied by compiler
with message : Error 86, invalid parameter for config parameter or value [w5500]

config Tcpip = noint , MAC = 12.128.12.34.56.78 , Ip = 192.168.1.88 , submask = 255.255.255.0 , Gateway = 192.168.1.1 , localport = 68 , [b]Chip = W5500[/b] , Spi = 1

while i believe, that the communication between the Arduino mega and the Arduino shield may work not properly,
i checked out these interconnection between and i have found this connections between the ATmega2560 and the W5500 chip over all connectors, from Pin to Pin.

what confuses me, the "ss" of Atmega refers not to anything of the ethernet shield.
the /res ends to the reset circuit on the shield.

sck and mosi are provided via 74LVC1G125, ok, these are only buffers, so should not cause problems...

please see table below:

' SIG------2560-----Port---------header #nr-----ISP on----------ISP--------------------------------------------------W5500
' _________________________arduino board_arduino mega_arduino eth shield2

' SS------- Pin 19---PortB.0-----header #53----no
' MISO---- Pin 22---PortB.3-----header #50----Pin 1------------ Pin 1 MISO -------- direct ------------------------- Pin 34
' SCK----- Pin 20---PortB.1-----header #52----Pin 3-------------Pin 3 SCK --------- via 74LVC1G125 ------------- as SCK3 --- Pin 33
' MOSI---- Pin 21---PortB.2-----header #51----Pin 4------------ Pin 4 MOSI ------- via 74LVC1G125 -------------- as MOSI3 -- Pin 35
' Reset---- Pin 30---/res----------reset-----------Pin 5------------ Pin 5 reset ---------to reset circuit on shield.. not to W5500

at the hardware i have no clue how to connect "alternatively" the "ss" to the ethernet shield.

@Paulvk , thank you for the hint, i will check the SPI enumeration of webserver examples

remembering.....my problem was, not having a response while ping the arduino....

on my first used hardware, consisting of an arduino mega + ethernet shield2, i have found that the ethernet shield hardware is fault, i never have got a proper function of it.

after many retries, while i was in the believe, something with my program code/configuration may be wrong, i found the conclusion to order two more arduino devices, but not the types i already have from arduino.org, i ordered 3.party clones, in my case from the supplier "eckstein-komponente.de". They delivered me as a bundle two "arduino mega compatible" + two ethernet shield with the W5100 chip .

Tested with an arduino code example, both units worked well, the ping was successful responsed which gaves me the confidence that my pc network/switch IP config, cables etc. was already fine. Then i tested my "old" arduino+ethernetshield and it has gone failed, "....as expected". With the new modules, i call it "eckstein ethernet shield" i tested the arduino.org arduino mega and it was fine, so the arduino.org ethernet shield2 was isolated to be defective.

then, next step, confident im my hardware now, i began to check bascom code on the eckstein arduino mega+ ethshield. First try runs bad, then i took an unedited example, edit only the IP and runs again, and it has worked.

As far, no w i have worked out two pieces of bascom code, the one worked, the other not, and i stripped all of the code what was not necessary only to get the ping response.
Only few lines has been left.

this small code is enough for getting a ping response:

this code works............................

--------------------------------------------------------------------------------------------------------------------------------------------------
$regfile = "m328pdef.dat"
$crystal = 16000000 '16MHz
$hwstack = 100
$swstack = 100
$framesize = 400

Config Spi = Hard , Interrupt = Off , Data Order = Msb , Master = Yes , Polarity = Low , Phase = 0 , Clockrate = 4 , Noss = 0
Spiinit

Enable Interrupts

Config Tcpip = Noint , _
Mac = 1.1.94.127.1.255 , _
Ip = 192.168.80.10 , _
Submask = 255.255.255.0 , _
Gateway = 192.168.80.254 , _
Localport = 1000 , _
Tx = $55 , Rx = $55 , _
Chip = W5100 , _
Spi = 1

--------------------------------------------------------------------------------------------------------------------------------------------------------------

... and this code works not, means, NO ping response:

$regfile = "m328pdef.dat" ' specify the used micro
$crystal = 16000000 ' used crystal frequency
$hwstack = 100 ' default use 32 for the hardware stack
$swstack = 100 ' default use 10 for the SW stack
$framesize = 400 ' default use 40 for the frame space

Config Spi = Hard , Interrupt = Off , Data Order = Msb , Master = Yes , Polarity = Low , Phase = 0 , Clockrate = 4 , Noss = 0
Spiinit

Enable Interrupts
' before we use config tcpip , we need to enable the interrupts
Config Tcpip = Noint , Mac = 1.23.45.67.89.01 , Ip = 192.168.80.10 , Submask = 255.255.255.0 , Gateway = 192.168.80.254, Localport = 1000 , Tx = $55 , Rx = $55 , Chip = W5100 , Spi = 1

Print "Init done"

------------------------------------------------------------------------------------------------------------------------------------------------------------

the codes, independent from the format, are the same until this last line in the second code snippet:

[b] Print "Init done"[/b]

surprisingly, i found that as i have deleted the print command, this code snippet responses also the ping. But i do not know why............

Conclusion overall:

it seems to be that arduino devices have a variety in product quality of the boards, the last examples i ordered from a 3rd party manufacturers was much much better in quality than the parts from arduino itself. Specially the press-to-fit pins seems to be a problem, i soldered all and i found that some vias on the pcd was damaged by the press-fit pins while inserted. I stuck lot of time on a defectice board while i never really believed that a new piece could be dead.

second reason, obviously, the print command after config tcpip does something, preventing the board from responsing the ping.

About ISP @ mega2560 module+ethernet shield:

last but not least: arduino uses a most a bootloader, but for my hardware, an arduino mega2560 + ethernetshield, i prefer to upload code via ISP, although for that reason to have the USB free for serial application. on the hardware you will see, that if shield is plugged onto the 2560 module, the ISP connector of the 2560 is occupied.
As a simple solution, i soldered a 3x2 2,54 pin header on the upper side of the shield, top on the solder pads where the ISP socket of the shield is mounted. This way i have the ISP interface "extended" and i can reconnect it to my STK500 again......business as usual can run once more.

i must say, i worked a lot with bascom on my own designed PCB hardware, not so much with prefabricated modules and ethernet applications where new....i was a newbie on that.
I hope my short story helps others to ship around the obstacles.... Smile

is there an END after the code?
it appears the MAC address is different.
There are a number of examples in the samples\tcpip\w5100 folder. you best check them.

i think i mentioned it before ; arduino is nice for proto but because of bad connectors, it is not usable for a production. at least IMO. do not assume that something you buy new is good. it can be fake or just badly tested.

hi Ingolf
Thanks for having us explain your approach.
Indeed the "shield" and the ready to serve modules requires lots of connections, wires ...
and, therefore, increases the risk of failure. unfortunately I know Crying or Very sad

! Like you I use them for proto, but after, I realize my own C I.

Hello uhrmacher

Having worked with making a web-server with the AVRs I found most too limiting
So I designed my own board to take the Mega 1284P and the Arduino shield
The reason for the 1284P board
20Mhz clock
10Mhz SPI
16K of ram <very important for buffers
Need real time clock with battery
3Amp switching power supply with polarity protection and screw terminals
Buffered RS232 with cable headers
Proper cable header for cables to ports
Resistors and cable header for I2C port
Small board same size as shield
Able to disconnect SPI from shield
second SPI header for programmer
all parts big enough that I can solder by hand

I posted here the files to get boards made https://www.mcselec.com/index2.php?option=com_forum&Itemid=59&page=viewtopic&t=13658
cost me $40 US to get boards 10 made including shipping

My two cents...

Do you remove your programming cable after flashing?

I read that you are using the STK500 icsp cable. That is connected to Mosi / Miso and CLK.
