 |
|
Still a long way to go but the first steps have been made. Bascom-8051 and the iMCU7100, a 8051 with hardcoded TCP/IP from WizNet. Changed the REG51.DAT file a bit, adding the extra registers of the W7100. And now, with a simple program, the three LEDs on PORT0.3, PORT0.4 and PORT0.5 are blinking. This is the board, you get when you enter the Circuit Cellar Wiznet contest
And here a picture of the WizISP, the program is put in the W7100 through the serial port.
The W7100.DAT file can be downloaded from my weblog http://benshobbycorner.nl
It is just a beginning, LCD not working, serial port not working (all things working with the timers). Have still some reading of datasheets to do.
Have fun

All working now on the iMCU7100.
Check http://benshobbycorner.nl
For 6,90 dollar you get an 8051 with hardcoded TCP/IP. If you look at the iMCU7100EVB board you will see you only need a handfull of components to get TCP/IP working. Standard 8051 SFR, extended SFR. 64 Kbytes flash, 64 Kbytes RAM, 64 Kbytes for TCP/IP. 8 sockets.
Have fun

|
|
Seems to be that I am the only one working with the W7100 
W7100 uses a bootrom to flash the code into the chip and to read and write the data flash. A call to &H07FD after filling some registers should do the trick. But I don't like the idea of some mistery code in my program so time to read the bootrom.

Have a very nice application running at the moment, but the W7100 has no EEPROM to store IP, Gateway, netmask so I am trying to get the dataflash 'working'.
Have fun

The W7100 has 256 byte of dataflash. It can be used to store IP-number, NetMask, Gateway, MAC etc. during configuration. You can access it by using a routine in the W7100-bootrom
Here is the code:
| Code: |
$regfile = "W7100.DAT"
$crystal = 11059200
$baud = 115200
$default XRAM
$large
Tl1=&HFC
Th1=&HFE
$romstart = &H0800
Dim Dataflash(256) as byte
Dim Q as word
Q = varptr(Dataflash(1))
Wconf.7 = 0 'no reboot
Wconf.6 = 0 'activate bootrom
Tmpr0 = low(q)
Tmpr1 = high(q)
Ispaddrh = Tmpr1
Ispaddrl = Tmpr0
Ispid = &HD2 'read
Call &H07FD
Wconf.6 = 1 'deactivate bootrom
End |
In the code an array called Dataflash is dimensioned and a pointer is set to the address where it is stored in external SRAM (Q). The write is almost the same, you only have to change the Ispid.
The $romstart = &H0800 is done to allow the bootrom code to be loaded in the lower part of Code memory. With Wconf.7 you can tell the microcontroller you want a restart after finishing the bootrom-access, or you don't want a reset. With the Wconf.6 you activate the bootrom.
I also found out that $default Xram can be used for all variables but the strings. The strings has to be stored in internal SRAM.
It still is a very nice chip.
Have fun
