Hello,
i´m using the K8055N kit. My question belongs to the ADC.
The PIC which is used on this board has an 10 bit ADC. Why does the board only supports 8 bit?
Is there a possibility to use the 10 bit ADC?
Thanks!
My guess is that the firmware is still using the same HID message formats, the original K8055 used, to communicate with the PC. There is no room for 10 bits in that format. But that is just a guess. I haven’t looked at the new DLL code that closely to be sure.
I don’t have a K8055N (yet). I modified my K8055 to a PIC18F2550 chip and am using 10 bit ADC as well as PWM. That firmware and the corresponding DLL are work in progress, but the sources are available here jannicash.info/k8055/
That firmware will most probably NOT work in the K8055N. The 18F24J50 is not pin compatible with the 18F2550. But it may be a point to start from, if you want to get into microcontroller programming.
If you do, don’t overwrite the pic you have. You cannot get the .HEX files needed to put it back to factory defaults. They are cheap enough to get a few to play with (like $3.50 a piece). All you need is a pic programmer that can connect to the ICSP header on the K8055N. Once you’ve exchanged the chip with an empty one, you don’t even need a bootloader to write new firmware into it. The firmware development environment, C compiler and tons of examples are free downloads from Microchip.
