Hello RIOT Community! For an IR based communication protocol we currently use direct port register access for accurate timings. I now want to port this code to more generic gpio_set / gpio_clear functions, but they are much slower. The resolution of the gpio_t takes more than 20 assembler instructions onour board/cpu (msp430) and the timing does not work anymore. Is there a fast and generic way to set and clear gpio pins? If not, what are my alternatives for accurate cross device timings?
Thanks Gero (new research engineer at CITI Lab, Inria, Lyon)
