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...
Hello,I've started to develop with the Riverdi STM32 Embedded Display and I'm trying to use the CAN BUS to display data, but unfortunately I can't. I'm not receiving any data. The CAN on the board is a FDCAN and I've set it to classic, because that's...
After STM32H5 I3C initialized as a controller, without any IBI, HotJoin Enabled, pull low SDA line will case SCL unstopped-toggle, as figure I had searched STM32H563 Errata 2.5.13, and got something likes this behavior :I3C controller: unexpected f...
Hello, I'm developing RTOS environment of dual-core in STM32H757.To write the data, I'm using function "HAL_FLASH_Program".The stack size of the task : 512 * 4float32_t g_temp_data[70]; // the data 1. Is it common for data to be written to Flash Ban...
We need to continuously DMA a single 16-bit word to the SPI transmitter. (Neither the memory address nor the peripheral address would increment.) Can this be done without intervention? I.e. do we have to use a DMA Complete interrupt to set a flag and...
