I am using ADC channel with DMA to get linear hall sensor data ,its giving bur after some time adc pin not working.
but same code working with another board, what can be problem.
Hi !
I am very happy to start STM32F1 Series for IOT projects. So i have experience of arduinoide software tool and STM32cube is new for me so which one will be best for smooth work ?
