Please help in general understanding of STM implemenation of RTC Calibration, Synchonization, Reference detection

Hello,I'm struggeling a bit in understanding the whole features of possible RTC improvements. General information, right now I'm using a STM32L051 and a external 32,768kHz Oscillator for the RTC. It's working in general, but the OSC has +/-30ppm whic...

SSI Implementation

Hello,We are using STM32G431KBU6, and we would like to incorporate Hardware SSI, i.e. send data via DMA, or at least send every 32 bit chunk via DMA.So far we were only able to do implement Software SSI (an interrupt per host clock).Your advice is ap...

Is there a trimming example for the nucleo STM32L4R5ZI?

Hello!I have ported overt X-CUBE-CLKTRIM to the STM32L4R5ZI Nucleo board. Unfortunately the callback HAL_TIM_IC_CaptureCallback is not called. Which results in the HSI and MSI frequency measurements to be calculated as 0. I have put a function genera...

hello, I have a question, which library do you use actively in keil, generally low level?

STM32H747 with Low-Power SDRAM (1.8V) read/write issue

Hi Everyone: we now have a problem running STM32H747XIH6 with Low-Power SDRAM (ISSI IS42VM32160E-75BLI) when the SDRAM clock is set to 100MHz, on our customized PCBA. I'd like to check if anyone has suggestions on how to debug.■ Description of the s...

Problem using Nucleo-H723ZG dev board with custom design (NRST related)

I am attempting to use the on-board ST-LINK V3e on a Nucleo-H723ZG development board (MB1364E) to communicate with a STM32H723 on my custom board. I have found what I think is a bug or oversight when I use the MIPI10 connector (CN5) with a Tag-Connec...

STM Nucleo Boards SPI Master/Slave Communication Problem. I set up a Nucleo-F446R as Slave Full Duplex and a Nucleo-G431R as Master Full Duplex. Master Sends -- Slave gets garbage.

The Slave Code   while (1) { //Slave Section // Check If Data is about to be received Spi3_CE_State = HAL_GPIO_ReadPin(SPI3_CE_GPIO_Port, SPI3_CE_Pin); Spi3_CS_State = HAL_GPIO_ReadPin(SPI3_CS_GPIO_Port, SPI3_CS_Pin)...

Periodical data transmit configuration

Hello,I am using STM32L0 MCU and trying to write a code which would include: Periodically transmitting data1 to UART.Constantly waiting for data2 (period value) from UART. If data2 (period value) is received from UART, change value of data1 transmiss...

I am trying to use a nucleo-f746zg as a slave using SPI6, but it seems to be dropping the first bit.

Hey guys,As I said in the title, I am using SPI6 on my nucleo-f746zg board as a slave. I have it set up to interrupt when a GPIO is low and then it it tries to receive/transmit using the HAL_SPI_TransmitReceive_IT function, but it seems to always int...

Rotary encoder interrupt per rotation

Hi all.I have a rotary encoder which generates 512 ticks per rotation and I would like to generate a single interrupt once the rotary encoder has done a full turn (512 ticks). What would be the best approach? I'm currently looking to see if the STM32...
