STM32 MCUs Products

RTC Internal timestamp is only updated when the first time RTC is initialized and power shifted to VBAT. On further power up and shutdown events that RTC Timestamp registers are not being updated with new time stamp values.

 I'm reading TS and clearing TSF, ITSF, TSOVF flags upon power up. But when power cycle happens again, the TS registers are still containing the previous value, but not present value.

My microcontroller clock capture does not work correctly It can trig only on raising or falling edge and can not detect both of them. How I can solve this issue? it is stm32f030k6t6

How to read the channels of the MCP3208 ADC with SPI STM32F103C8T6 ???

Hello ST community!I would like to know if someone can help me with my project, I need to read the analog measurements that enter the MCP3208 ADC through SPI with STM32F103C8T6. I need to read all 7 channels of the MCP3208. I've been reading the data...

Automatic DMA 32bit -> 4 byte UART transfer?

Interface with external ADC

CAN example doesn't work between HAL and SPL.

I have two STM32 based development boards and would like to get CAN example (slightly modified) to work with a simple data packet of 2 bytes sent from one board to the other. But I detect no valid CAN frame on the bus.The setup is taken from here: ST...

Correct TRGO selection for interfacing timer

I'm confused as to what MMS bits I should choose as TRGO for an "interfacing" timer.A timer is used to trigger COM events on another timer.Its slave controller is configured in Reset mode, so it's automatically reset on any edge change on TI1, for ex...

Bare metal timer-triggered multi-channel ADC conversion using DMA (STM32H745)

Try as I might, I cannot get timer-triggered ADC conversions of three channels working using the DMA. I've managed to get it to run for a single channel and using ADC triggered interrupts (no DMA). While adapting my code to work with DMA, I leaned on...
