STM32 MCUs Products

I have a P-L496G-CELL02 pack with STM32L496AG MCU with LTE Cellular Expansion board. I downloaded the package FP-ATR-LTE1 and imported the package into STM32IDE. The build fails with error.

Here's the error that I get:"c:\st\stm32cubeide_1.9.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.0.202111181127\tools\arm-none-eabi\bin\ld.exe: cannot use executable file '../../../../../Boo...

Is TIMx_DMAR 16-bit wide in 32-bit timers?

Probably no and this is probably documentation flaw across all STM32 RMs.JW

I am using NUCLEO-H723ZG and I am trying to use SPI the spi3 as SPI MASTER to the SPI SALVE device without success using DMA. I see the perfect data in the MISO line, But I unable to receive it into the "rx_buf", always "ZERO".

static void MX_SPI1_Init(void){ /* SPI3 parameter configuration*/ SpiHandle.Instance = SPI1; SpiHandle.Init.Mode = SPI_MODE_MASTER; SpiHandle.Init.Direction = SPI_DIRECTION_2LINES; SpiHandle.Init.DataSize = SPI_DATASIZE_8BIT; SpiHandle.Init.CLK...

I'm getting sporadic I2C bus errors with no terminating ACK

I'm using STM32H743 I2C1 and FW as of december 2021.I'm testing in continous loop PMBus communication (straight I2C master interface).Appr. all 8h I'm getting a sporadic bus error.A good transaction looks like:this is a register read (addr-len=1) for...

STM32H743 Config JTAG PB4 As Gpio Output?

hi when i use normal configuration for define this pin(PB4 in STM32H743) as GPIO output a problem occurs in the program.This pin is connected to the JTAG port and i use only SWD mode and pull up this pin by 10k to VCC.plz help me to config this pin a...

STM32H750 flash access

Hi,I have two questions regarding STM32H750:1) I would like to pre-burn its internal flash with a simple code that enable XIP (execute in place) from external SPI flash and jump to some initial address on this external flash. Then I like to permanent...

Delay between UART TX frames at high speed

I am sending a fixed-sized buffer (512 byte) at 8 Mbits/s via UART out of an STM32F3, and I am experiencing what it seems to be a fixed delay (~ 2-3 bit periods) between consecutive frames. In the screenshot below, after sending the dummy value 01010...

why isnt my encoder counter going down wen i turn the encoder the opposite way im new to programming and cant figure this out im using the stm32f407 btw im using cmsis not hal
