So, I installed LibUSBDotNet and compiled the Show.Info example and the product field says CCS HID Demo, so I don't know why Windows is blank??

Odd, it works, just the descriptor missing, is it a Windows 11 thing?

I tried the CCS example and that tab shows nothing, it's blank.

Yeah, I was more after changing the description, I changed that file, but Window 11 just shows it as a "USB Input device", it doesn't even say "CCS Demo", does Windows 11 not show ...

Apologies if this has been answered before, I had a quick scour and couldn't find what I wanted.
I am after changing the HID and PID so it shows something meaningful rather than "USB Input Devic ...

Fair point, I should have said every other compiler I have used.

BYTE loaded_code
Yeah that doesn't work, when the EEPROM is cleared it shows 1 instruction where it should show 0, which the for loop does.

Yes, the do while loop does the same thing though, yes I see the issue of evaluating the byte before reading it in, I could do an EEPROM read before going into the loop, but the for loop works as expe ...

Remember integers in CCS by default are unsigned....

-1 = 255
Do they? I didn't realise that every other compiler defaults to signed.

It increments before it reads so in reality it always reads x[0], with the for loop I can set it explicitly to 0, do while didn't work either until I put the increment above, very odd, never had that ...

I can get around it by reverting to for loop or setting the variable to -1, which seems to work

Yesh that's what I thought but the int long came from ccs c driver folder, , changing it to unsigned remains the same, maybe it's because it's only 512?

number_of_lines is defined as EEPROM_ADDRESS, and for 2404 it is a long int,
The fix was to move the variable increment to the top before the assignment.
while (loaded_code[number_of_lines&# ...

Going back to the old code, number_of_lines goes from 0 to 511 then 767 to 985 for some reason but the data is correct it just doeesn't stop at byte 29 which s 0xff, the for loop goes from 0 to 28 whi ...

the array is all 0's before the loop starts, so it would only read 0xff from within the loop after it has read the E2PROM.

This code works:


for(number_of_lines = 0; number_of_lines < EE ...
