Supporting other PIC chips
Hello
I have been working on a 433MHz control system using a PIC16F and decided to move it to PIC18F due to only having 8 levels of stack in the PIC16F. I looked at the PIC18F2550 but it has a shared SPI and UART pin. Because it has to be very small I decided it was too much trouble and have designed a new circuit board using the PIC18F26K20 which is much like the 18F2550 but with a few minor improvements and no USB. I think the removal of USB was the key to getting the SPI and UART fully functional. I suppose Microchip decided that if you have USB then the UART is less important.
I think Pinguino would be more versatile and maybe more popular if it supported some other PIC18F chips, and some without USB. I would be interested to know what was involved in supporting other chips with a minimum of fuss if anyone knows.
I guess the USB interface and bootloader make it simple to use for beginners and this is very good for most one-off or hobby projects. Maybe anyone wanting to go further is more advanced and can use command line C and ASM tools.
