Hi,
no, new changes for array passing is not down compatible...

But at all i think, that your project is only usable for Bascom full version and those users can update bascom easily
Very Happy

thanks for your work!

best michael

Hey guys,

I checked Mr Six's changes. The whole routines are different. This means the examples from opollas webite are not the latest?

In the meanwhile I have read six1's attachments and it took a while for me to understand.

However two questions remain:

1) did I understand correctly that instead of the checks in the main loop (originally by opolla) I have to call these subs in the main loop??
Do
Resetcounter = 0
Call Usb_check_reset
some_variable = Usb_check_rx()
.
.
.
loop

2) check the attachment I get a compilation error when using opollas original usb setup from the hid keyboard. Can someone who knows about USB please explain what this constant is used for?
If I get that correctly that array should only be called if the constant is existing (maybe a bug??)

what bascom version are you using? this works only 2.0.7.6 and up!

Hi Iam using 2.076, I unfortunately updated befor reading this here Sad

After adding Const _usb_Endp3Addr = 2
the code is compiled, but my PC still does not recognize.

I basically kept the schematics, only changed point is a 3V line regulator, which i added.

I also tried swapping D+/D- (in case i made some mistake)

I cannot see why the program wont work Sad

Maybe someone with swusb experience can have a look?

did you use the new files from previous page (Array corrected)?

Sebastian.Heyn · Joined: 13 Apr 2005 Posts: 86

Yes I used them,

I did not have the declarations and routines before - on opolla's page for example the hid keyboard is only one file.

Before that I had tried exchanging the array txstate.... but it also didnt work

DAMN,

forget what I said.

It was a hardware problem. The crystal did not oscillate.
Why on earth didnt I get an errot message from the programmer?

I was not blaming bascom for this, as I use the stk500.exe (avr isp mk2) Smile

I would never complain about bascom as it helped me so often not to use asm or c Smile

(sometimes you have to use asm, but thats fine)

One Question:

Can I get it to act like 3 usb devices at the same time? I want it to be able to send 16 Key pushes simultaneously, but each usb hid keyboard can only push 6 keys at the same time.
If thats not possible, i need to process the 16 inputs seperately and make the program prioritize which buttons to use...

Mr.Ollopa how can I add this strings to library?:

It's a 18-LEDs Light Music Unit with 256-bit PWM: http://lightportal.at.ua/publ/kombinirovannye/koshachij_glaz_4_versija/11-1-0-64 (sorry, site is only in Russian, but program multilingual)
It works fine, I synchronize PWM with USB (to avoid interrupt conflict) in main circle after receiving packets with this three strings. But without this packets synchronization lost and interrupts conflict occurs, therefore I must disable PWM. Also it disable at the start.
However, without incoming data, every 8ms happens INT0 from USB. It will be fine to synchronize within library, independently of incoming data. This will allow to add Background Running LEDs effects in this unit and make more serious projects.
