Problems with Debug on STM32F4 discovery
Posted on November 09, 2013 at 21:11
but the program does not stop never on the breakpoint at lines 80, 82 and 84 (ADC3ConvertedVoltage = ADC3ConvertedValue *3300/0xFFF; GPIOD->BSRRL = LED6_PIN; GPIOD->BSRRH = LED6_PIN;) but only at lines 81 and 83 (x=x+1; y=y+1;)
has someone already had a similar problem?and can give me suggestions?
thanks
if shoud to be help I have attached the main
Hi,
I bought a development board STM32F4 discovery. I wanted to try the debug and I modified the example ADC3_DMA in STM32F4-Discovery_FW_V1.1.0 in this mode:
but the program does not stop never on the breakpoint at lines 80, 82 and 84 (ADC3ConvertedVoltage = ADC3ConvertedValue *3300/0xFFF; GPIOD->BSRRL = LED6_PIN; GPIOD->BSRRH = LED6_PIN;) but only at lines 81 and 83 (x=x+1; y=y+1;)
has someone already had a similar problem?and can give me suggestions?
thanks
if shoud to be help I have attached the main
