In a project built using STM32F103, I have used TIM3 for some of my frequent tasks (like LED blinking and setting some flags etc.), which work perfectly. Today when I tried to enable ADC1 using DMA Circular, it looks like the TIM3 Global Interrupt ha...

Hi,Trying to use I2C1 with REMAP=0 and as long as understand the SCL and SDA pins are PB6 and PB6. Along with I2C I am using some other peripherals as well. I am unable to select PB6 for I2C SCL PIN. Please see attached screenshot. Not sure why it wo...

Now, I have another question.. Instead of circular dma, I just did it normal dma.. and I call the ADC_Receive_DMA every 2 secs (from my main loop). I have voltage supplied into 2 channels out of 5. Now at every interrupt call, the value of the DMA bu...

The ADC, just reads 5 channels and store into the DMA buffer. Right now the interrupt does not do anything more. The TIM3 interrupt only toggles 4 leds on the system depending on their OFF and ON duration settings. Here is the ADC Handler void HAL_A...

Yes, I do understand that @waclawek.jan ,Then what is the way to use TIMER and ADC DMA at the same time?

Thanks for pointing to that.. That makes sense. So basically, CubeIDE must disable I2C1 and I2C2 completely if SPI1 is remapped, as PB5 is common (SMBA Pin). Is that correct?
