Hello,I am new to STM MCUs and need to test the different peripherals of the STM32H745 to decide if it fits my project. I began with the GPIO_EXTI example, and it worked. Later, I tried to configure a USART for debugging purposes, but it didn’t work....
Hi,Currently I am trying to measure MCU junction temperature on the STM32U575 via ADC4 TEMPSENSOR channel (CH13). Upon reading the datasheet and reference manual of the chip, I have some questions regarding this implementation.According to both the d...
Dear Forum Members,I'm developing a hardware with a small LCD screen which is using a QSPI interface. I succeeded with an STM32H723 with its OCTOSPI interface through DMA, and I got good results, but I encountered memory mapping problems with the com...
Dear, Can you confirm that OCTOSPI P2 is available only on WLCSP208 and TFBGA216 packages of this series? I wanted to use both OCTOSPI interfaces in LQFP144, but noticed that there is missing only OCTOSPIM_P2_IO3 line in it, so my conclusion is tha...
I've been trying to get DMA to work on the STM32H7S3L8 with bare metal code. As far as I can tell, I have everything set up correctly(?). I get no DMA error flags. The DMA complete flag is never set and the target buffer remains empty.I have enabled ...
I used to use stm32f4 series and moved to stm32g4 series to use the latest mcu.But stm32g4 does not support sdio.What is the popular mcu among stm32 series that supports sdio?Thank you.
HI everybody，I purchased this batch of MCUS and found a difference in performance compared to my previous batch 19+，Unusual: The upper left corner is the standard source output setting, and the right side is the data detected by the product. Focus on...
Hello! Not sure it's the right place to post. I have a custom board based on STM32F767. I'm using USB with VCOM port to communicate by UART. Basically it works (I mean, I can receive bytes from a terminal (I'm working on Ubuntu with STM32CubeIDE v. 1...
Hello,I am working with an STM32 G4 series microcontroller and using the ADC in DMA mode to handle continuous conversions. My goal is to SET a GPIO (debug pin) at the start of an ADC conversion and RESET it at the end of the conversion.Currently, I a...
In order to make it easier for others to upload software, I decided to add the HID Bootloader:https://github.com/Serasidis/STM32_HID_Bootloader it is small and effiecient uploaded this to Bluepill (both jumpers in "0" position) $ ./STM32_Programmer.s...
