STM32L412 LPUART with ST232

Hello,STM32L412 will be in stop mode 2 with LPUART. This device is a slave device, master device wakeup on time schedule and gather data from it by RS232.ST232 is powered by master device. But issue is that when ST232 power is off by master, then it ...

How to find out the type of FDCAN transceiver in H755 and H743 boards ? Is it the MCP2562FDT ?

I looked the datasheet and reference manual, not mentioned there.

The specified A/D datasheet performance shows a typical SNR of 69dB. Measurements on the EVM give values of 81.8 dB. Does this family of parts usually run that much better than datasheet values?

What is the thought of putting two processors in parallel sharing all but one pin. And only one is active at a time depending on the state of the one pin at reset?

I have a system that needs to run for years. But is in a place where it cannot be maintained. The desire is to have two processors, one running, and one in backup. The second can be powered down, or powered up, but in lowest power sleep mode. If a pr...

IRQ from SPI DMA Rx Complete before end (too early)

I use an SPI interface with Rx and Tx DMA to transfer a 22 byte buffer from a spi slave. Chip select is handeled withLL_GPIO_ResetOutputPin(TDK_nCS_Port, TDK_nCS_Pin);set to high again to end transfer I wanted to use:// SPI5 - IMU TDK Rxvoid DMA2_Str...

backup SRAM (available in the lowest-power modes)

The backup SRAM cannot be accessed in the (normal) Run mode ?

1.board-NUCLEO-H743ZI2 . we are dumping code into flash externally through USB .for that we are making boot0 pin high and low manually.is it possible to make boot0 pin high and low in software. I don't have access to change boot0 pin in MX.

we are not able to change boot0 pin in MX configuration. for other input output pins we are able to change the configuration but not for boot0 pin.Thanks in advance.

FDCAN between two STM32H747 MCU boards

I would be interested in implementing a FDCAN communication between two STM32H747 MCU boards. I have implemented communication on a single board in External LoopBack mode. However, I am having problems understanding how to connect the two boards. Do ...

Problems sending SPI Data from STM32 to arduino

I'm trying to learn how to communicate via SPI with STM32 but I've run into some problems.The first step i took was to implement SPI communications using two arduino unos: the master writes a byte and the slave responds with another byte according to...
