STM32F103C8 internal Temp sensor on which channel? ADCx_IN16 or ADC1_IN18

Hireading the ref manual of the STM32F103C8, it says in chapter 11.10 that the temp sensor is internally connected to ADCx_IN16. In figure 39, it says that the temp sensor is connected to ADC1_IN18.I reckon that this is a simple typo, or do I miss an...

STM32L452 DMA + SDIO Overrun Issue

Hi Guys,I'm currently using an STM32L452 device and i'm having some problems with the SDIO when using it with DMA.I have configured DMA and SDIO usign the file generated from STM32Cube tool.When I try to read the SD card without using DMA , everythin...

Once the DAC DMA is started, do I need to stop it in order to change the content of the buffer? Or I can simply do a HAL_DAC_Start_DMA() again with an updated buffer?

Is there a way to trigger an interrupt that fires a different method from a UART IRQ?

I got some excellent advice on a previous question and have a new related question. I have a app that needs to run a control loop at a specific rate with something like a few percent jitter. For example, if the control loop is supposed to run every...

STM32H750 minimal code to blink GPIO

I am using a self compiled arm-none-eabi gcc 10.2 toolchain and I am trying to write a minimal program to switch on a GPIO LED (putting that output to 0 because is cathode connected) on pin PA1. I have the following resulting binary:Disassembly of se...
