CH_CFG_ST_RESOLUTION == 64 : compile error Topic is solved
Posted: Sat Oct 31, 2020 9:51 am
Hello,
This is for chibios 20.3, using RT.
From what i see in chconf.h :
setting CH_CFG_ST_RESOLUTION to 64 is permitted (and useful when using tickless mode with high frequency).
but osal.h dont permit to do so.
here is a patch that permit 64 bits resolution :
also, in each chconf.h example file, there is a doxygen note that need to be modified :
@note Allowed values are 16 or 32 bits or 64 bits.
