Run FW AP and FBW on two different boards

[dewagter]

Use 2 (Lisa) boards connected via serial cable to separately run AP and FBW.

Just my 2cent:

• To me it looks like the link_mcu*.h header files should be refactored into one common one...
• I'm wondering why the UART implementation does not have/need a checksum??
• The old link_mcu.c should probably be renamed into link_mcu_spi.c
• the CAN implementation has SPI stuff in there, but commented out... should be removed
• please no explicit LED numbering, we have way to many boards and configs...
  • e.g. introduce LINK_MCU_LED that will be used if defined, just like for the other led indicators

[dewagter]

• renaming, common header and LED sound like good ideas
• there is a checksum: https://github.com/paparazzi/paparazzi/pull/297/files#L8R55
• CAN implementation not fully operational (yet)

About the checksum: what I meant is why do SPI and CAN implementations have a checksum, UART not??

[dewagter]

the link was supposed to go to lin 55 of link_uart.c which shows there IS a checksum in the UART.
(but the link gets processed:
https :// github.com/ paparazzi/ paparazzi/ pull/ 297/ files #L8R55 -> https://github.com/paparazzi/paparazzi/pull/297/files#L8R55

And also please remove the useless $ID and add proper doxygen headers for the files....

[dewagter]

is it ok now or should link_mcu also move to ./firmware/fixedwing/

[flixr]

If we want to do further cleaning like moving to firmwares/fixedwing, we do it in master..
