Re: UART and buffer

hi, in this period i have a similar problem, you can use Serial Driver in this metodology you can use 1) Event you can see this http://forum.chibios.org/phpbb/viewtopic.php?f=16&t=2944 or 2) use chnRead(&SD1,&bufferMsg,64); if you want use uart directly, you know is very hard to learn

Re: Serial Driver and CHN_INPUT_AVAILABLE

i fix it, the code that i write is good but i set the pull UP the pin RX for use it

Code: Select all

  palSetPadMode(GPIOA, 9, PAL_MODE_ALTERNATE(7)); //tx
  palSetPadMode(GPIOA, 10, PAL_MODE_ALTERNATE(7)); //rx
  palSetPadMode(GPIOA,10,PAL_MODE_INPUT_PULLUP);

thanks for all.
