And it works fine with a Dell L100 keyboard.
Thanks g4eml, for that info, i am work on the SD driver and file sys.g4eml wrote:Tried it with a 'Tesco Value' keyboard and worked fine, although I have to type slowly to avoid missed key presses.
Tried it with an 'ASDA ' Keyboard and it would not respond at all.
Both keyboards show up as the same manufacturer when checked in Linux. It looks like even small differences in model number can confuse the driver.
Working Tesco keyboard identifies as "Holtec Semiconductor Inc. Keyboard" Vendor ID 04D9 Product ID 1603
Non working Asda keyboard identifies as "Holtec Semiconductor Inc. Shortboard Lefty" Vendor ID 04D9 Product ID 1503
I also noticed that if the non-working keyboard is unplugged the screen blinks off then returns.
Unplugging the working keyboard does not cause the screen to blink.
Congratulations on getting this far. A simple operating system with access to keyboard, screen and SD card (and maybe basic ethernet) that can run assembler or C programs would make a good embedded board. I will monitor your progress with interest.
