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...
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...
Hello, I’m working on a project with an STM32F446RE where I read data from a CAN bus at 500 kbps (CAN1_RX0) and also use I2C to control an MCP4725 DAC, plus timers and DMA for other tasks. The problem: When I test CAN alone, it works perfectly — I c...
Hi All,I am writing a code to generate an PWM at output. I want to drive an H-bridge outside.All initializations I have done.I am using TIM1 (advanced timer) for this purpose. I am using STM32F Discovery Board (Microcontroller is STM32F407) and STM32...
