I have been trying to get the 644P 'sanguino' to build and run, but it never initializes uart0 properly. Leaves out the initialization of the UBRR. The baud rate is defined in the INC. I believe that I have gone through the instructions as best I can, but they don't exactly (to me) match the 6.9 layout. I have been able to build from both the command line and MicroChip studio. I have been working with AVR for well over 20 years.
So, then I tried the UNO.hex and UNO.eep.hex on the Microchip ATmega328PB from the arduino directory. It appears the PB is not compatible with the UNO (I don't have another option). While it does run after any definition it tends to stop responding/hangs (for a bit). For example: *amforth 6.9 ATmega328P Forthduino> 3 4 + .7 ok> : x2 dup + ; ok> 2 x2 .* *amforth 6.9 ATmega328P Forthduino> 2 x2 .amforth 6.9 ATmega328P Forthduino> 3 4 + .* As you can see I get the banner and a prompt. Operations like add work until a definition, such as, x2. All seems fine after the 'x2' definition, but any attempt to use it fails. Using the definition of x2 will cause the banner to reappear after several seconds. Trying to print from the top of the stack also causes a new banner. The only way to recover is a reset/power cycle. The EEPROM no longer matches the original UNO.eep.hex file (not sure if this is normal or not).. I will continue to work things, I want to eventually augment my engine control unit with an ATmega64M1 via CAN. I have an extensive amount of CAN related software and peripherals that I would like to interface with FORTH. Any hints or suggestions would be appreciated.
