STM32 MCUs Products

1.Hi Sachin here im using STM32L4R9AI chip for our design but i am getting a issue like where the flash size is showing 63KB Actually the flash size is 2MB. . 2.It only connecting in Hot plug mode & not able to erase also .

STM32G431 SPI MCU <--> MCU Communication

I have 2 PCBs, both with STM32G431 MCUs, and both MCUs should communicate with each other via SPI. Both PCBs are assembled in a chassis, the distance between the two PCBs is aprox. 10 cm. For max. Signal integrity I have chosen to use LVDS as a hardw...

i can't display in Tera Term using USB virtual com with my nucleo-G431RB, although every thing is alright ,the code is correct , the port is connected . Can you help me please

How to use two or more timers independently from each other using the stm32h7?

Hello everyone,I am still relatively new to STM32 especially the stm32H7. ( I am using the stm32h755)I have one timer with DMA that outputs a PWM signal, I am controlling an ARGB strip. For this I have Timer4 connected with Channel 1 and it does work...

Question on SAI DMA buffer

Hi Team,I am using a the SAI Peripheral from the STM32L5 family to read data from a master device. I am employing the DMA peripheral to read the data from SAI. I have a buffer of 32kb and I am using the STM board as a slave device. I am using the HAL...

Current consumption in sleep mode for STM32f401re

Hello Everyone ,I have a wrote a code to send STM32F401re to sleep with all peripherals on at 84Mhz , as per the datasheet i should be seeing a current consumption of 18-20mA, however I am seeing a consumption of 27mA. The code sends data through UA...

STM32 UART receives Null character(\0) on reset.

Project Details:The project consists of two STM32 MCUs connected over UART (without any external pull up resistors). One STM32L4 MCU (LPUART1) acts as an AT master and other STM32L0 MCU (UART 1) acts as an AT slave. AT slave is configured to wake up ...
