STM32 Custom OTA Dual Bank Config

Hello There,I'm working on OTA application and successfully executed single bank OTA.Now I'm looking to switch to Dual bank operation to make it more reliable. So, there are 2 banks (memory areas) and after each update, the active bank changes. Means...

How to implement Pulse counter on STM32H723?

Hi,In our application we are using a cooling system(i.e., a FAN/DC motor). For which I have implemented TIM1 in PWM mode to control the speed of the FAN, the story doesn't end here. The FAN provides a feedback which is called as pulse sensor which ca...

I use mcu (stm32l452rct6) + sensor("ADI" ADXL355). the interface is SPI. How to read sensor data???

Cannot send break condition via uart.I have a nucleo board 32l422 and i connected lora rn2483. I can communicate with module but when set this to sleep i cannot wake up module.I tried HAL_LINSendBreak with no success.

LORA DATASHEETThe default settings for the UART interface are 57600 bps, 8 bits, no parity, 1 Stop bit,no flow control. The baud rate can be changed by triggering the auto-baud detectionsequence of the module. To do this, the host system needs to tra...

SPI communication with X-NUCLEO-OUT02A1

I order the X-NUCLEO-OUT02A1 and I work with a NUCLEO-F746ZG.These two boards aren't directly compatible I know.But they communicate with SPI, so I'm sure that you just can implement the communication with a bit of mapping with some breadboard wires....

STM32H7 SPI DMA not working

STM32H7 SPI DMA not workingHi. I have stm32H745 nucleo board, in my project i want send data from MOSI via DMA (i did the same on old F4 discovery correctly).PE_14, SPI4 , DMA2_stream3, DMUX11=84 (for tx spi4)In project i need to send data (fb[][]) t...

STM32G071 ADC channel selection

I wanted to know which channel is converted latest. I configured as belowhadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc...

Problem with setting up LIS3DH SPI with STM32F0x ??!!

Hi Everyone. I have encountered a problem in using LIS3DH SPI with STM32F0x MCU. I used to configure and set LIS3DH accelerometer with ATXMEGA families without any issues but this time I really can not understand the origin of my fault. I'm using bar...
