Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hi ST community,I am using the B-L4S5I-IOT01A board to record 3 sec of 16 kHz audio using DFSDM + DMA, and then transmit it offline via UART (after recording is complete). Since two MP34DT01-M microphones are connected to DFSDM Channel 2, I configure...
Hi, I am having issues with threadX tx_byte_allocate throwing a hard fault exception. This only happens after some time of byte allocate and release. There are still plenty of available bytes according to the pool. But somehow in _tx_byte_pool_searc...
I'm trying to implement a USB touchscreen on a NUCLEO F446ZE. I'm making a full-speed device using ST's USB library (Custom HID class) and I'm testing it with on a Windows 10 host. The first contact registers, but when I try to press another, it doe...
I am currently experimenting with STM32F030RCTX and STM32F030CCTX devices.My goal is to use RS485 with auto-baudrate detection, since I have modules that operate either at 115200 baud or 500k baud.On STM32F030RCTX, I use USART1.On STM32F030CCTX, I us...
Hi,Master：MCU: stm32h743iiIDE:keilQuestion：There is a 32M external SDRAM, and the scatter file is as follows:LR_IROM1 0x08000000 0x00200000 { ; load region size_region ER_IROM1 0x08000000 0x00200000 { ; load address = execution address *.o...
Hi STM community,I’m working on a project with an STM32L031K6 paired with a Fujitsu FRAM MB85RC256V and an SHT31-D temperature/humidity sensor (on a breakout board). Both peripherals are on the I²C bus PB7 = SDA, PB6 = SCL.I’m trying to test the setu...
Hi everybody,On my project, my µC receives data from a rapsberry pi on a serial bus.For another project, I've used this method : https://github.com/MaJerle/stm32-usart-uart-dma-rx-tx/blob/main/projects/usart_rx_idle_line_irq_F4/Src/main.c to receive ...
NUCLEO-F411REI am trying to read data from a ADXL1002Z.I have set up my board to use PA1 (A1 on the Arduino header) as ADC1_1/* adc.h */ #ifndef INC_ADC_H_ #define INC_ADC_H_ #include <stdint.h> void pa1_adc_init(void); uint32_t adc_read(void); vo...
Recently, I encountered a tricky problem, I used STM32F405VGT6 this IC, but I found that it could not enter DFU mode normally, after repeated troubleshooting, I found that when the chip was USB probed, HSE was detected and did not vibrate, I also saw...
I have followed the article (https://community.st.com/t5/stm32-mcus/how-to-create-a-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308#memory-layout ) to get it working for ethernet but I am facing hardfault. In H7S3L8 I am using AXI-SRAM at...
