Any help is appreciated.
I am using the Nucleo-F303ze board with the STM32F303ze MCU. With development using the STM32CubeIDE version 1.12.1. I have set up 3 differential channels on ADC 1 and 3 on ADC 2 for 3 phase computations, with the scaled voltages on ADC1 and scaled currents on ADC2. For both timer ( timer6) triggered and software triggered modes.
In debug mode i use the "run to line" option with the cursor place on the line with the code:
adcConversionComplete = 0;
The first time, it runs through and i get some adc values, when i click the run icon again, the program does not stop at the cursor line. When i pause the execution, i observe that it has hung up on the line:
"while (adcConversionComplete == 0)"
My ADC pin selection pairs for my differential mode are:
ADC1_IN5,IN6 ADC1_IN7,IN8 ADC1_IN9,IN10
ADC2_IN1,IN2 ADC2IN3,IN4 ADC2 IN11,IN12
For the DMA i use a word size and normal (not circular) mode.
