spi in STM32H7

SPI in stm32h7 (stm32h743iitx in slave mode) don't work, receive wrong values.how I make spi to work correctly in stm32H7? its not clear at allthanks,

Are there any errors associated with the CAN Controller on the STM32F205ZGT6 MCU which could explain the CAN bus packet failures when the ambient temperature is increased to 40°C?

Hi,I wonder if you can help us? In one of our projects we are using the STM32F205ZGT6 Microcontroller and specifically we are using the CAN bus. The problem is that when we increase the ambient temperature around the MCU to approximately 38°C to 40°C...

Hello everyone, I am new on a project where we use the P-L496G-CELL02 kit, my question I would like to manage the sleep and wakeup mode. I searched for examples but couldn't find much. do you have any ideas please? thank you

stm32h725 injected ADC with timer 8

Hey all, I'm trying to trigger an ADC interrupt with timer 3 on the regular channel and timer 8 on an injected channel for both ADC 1 and 2 on the STM32H725, However, It seems like I'm only ever able to trigger the regular channel interrupt with time...

Trouble with FDCAN

Hello, I built a small CAN network using CAN 2.0 transceivers. I wanted to add some FDCAN devices using classic mode. However, I seem to be having trouble just talking to the transceivers. For instance, I have an STM32L432 (Attached to a Nucleo). ...

Is the MCU STM32H743IIT6 can enable 35 GPIOs at the same time?

Hi,I have designed a STM32H743IIT6 based board for controlling 35 optocouplers(4N35). These optocouplers should work at the same time(worst case). Each optocoupler will take nearly 10mA current. But I have seen in the datasheet as "Total output curre...

For a project, i need 7 32bits timers (clk around 8MHz ) : - 4 output generate (1 signal, 3 interruptions) - 3 input capture I expect to use 32-bits timers (TIMER15 and 16) . is it OK with STM32H753 ? Regards

STM32 for high resolution delays

Is it possible to use a STM32 for something like the following:Take in a pulse, interrupting on a edge.Use this edge to generate multiple (5 or so) output pulses (only the positive edge timing needs tightly controlled timing). The output pulses might...
