ADC With Callback STM32F0 Discovery//Debug Issues
Posted: Wed Mar 05, 2014 2:05 am
I'm not quite sure what is going on here
I have a shell which is spawning a adc thread. If i set it to synchronous with no callback, the code executes, however when adding a callback the program crashes on adcStartConversion.
Also- I am using os x, stm32f0 discovery, st-util and arm-eabi-none I cannot get the program to run through gdb. It loads fine however i need to unplug the device to see the program run. (which kills the debug connection)
Thanks

FALSE,

adcTempCallBack,
adcErrorCallBack,

};
void hello(void)
{
chprintf((BaseSequentialStream*)&SD1, "5787766");
}
void adcTempCallBack(ADCDriver *adcp, adcsample_t *buffer, size_t n)
