Using coprocessor (FT813)
Posted: Sun May 03, 2020 6:31 pm
Hello!
I could get started by using several examples and I'm able to initialize the display and write shapes using the RAM_DL
memory space. However, I still don't understand how to get the coprocessor working. Please look at what I have written (1)
When I use the RAM_DL part, (no coprocessor slider, #define COP_SLIDER 0), it works, and I get a white rectangle
on blue background.
As for the coprocessor "slider" command, I wrote it with wr32 and wr16 commands, but I'm not sure how to finish the list.
In the DL command method, there is write DLSWAP_FRAME command, but how can I close a coprocessor list?
Basically it does nothing. Coudld anybody tell me what's wrong?
Thanks
R.
(1) By the way, when I posted code with BB code tag, the form replied "forbidden, contains contacts, probably spam", I found
no other solution than taking a screen copy. Can anybody tell me how to post code? I used the BB code "code" (between
brackets) as on many other forums to post it, but it doesn't work.
Next problem, I pressed preview, not post, and it says: Forbidden. You sent forms too often. Please wait a few minutes.
I already waited close to 10 minutes (not checked, but in the meantime, I got one phone call, made a screen copy, etc...).
How long am I supposed to wait in that kind of situation? How long should I wait? (Right now, it works because the problem
was yesterday evening, but it would be nice to know approximately how long I have to work, and it would be even better
to be trusted because my first messgagses show (I think) I'm not a spammer.
