Bonjour,I've been able to use I2C to communicate with I/O extender and display drivers with HAL. I'm now trying to use the I2C with HAL using DMA.The problem is that UM1785 Description of STM32F0 HAL and low-layer drivers is a bit vague on explanatio...
Hi everyone,I’m working with the STM32C011D6 in the SO8N package, and I’m a bit confused by the pinout and remapping notations in the datasheet.In the alternate function table, PA11 [PA9] and PA12 [PA10] are shown for pins 5 and 6 respectively. From ...
Hello ST Community,I’m working on a project using the STM32G0B0VET6 MCU where the ESP8266 Wi-Fi module communicates over USART5. The ESP module’s TX and RX are connected to PD2 (USART5_RX) and PD3 (USART5_TX) respectively.In my current working firmwa...
There appears to be a discrepancy between the STM32U073 reference manual and the header file for the part. Given that STM32CubeProg seems to agree with the header file, I'm inclined to think it's an error in the reference manual.I'm looking at progr...
I am working on a project using an STM32G4. I have a new board spin that I am bringing up and one of the four boards that I have brought up is exhibiting strange behavior exiting STOP1 mode.I have code that can put the micro into one of 2 low power m...
I have designed a PCB that connects an Artix-7 XC7A35T-1FTG256C FPGA with an STM32F469VET6 (LQFP 100) MCU. My goal is to transfer data between these two devices, with the MCU as the QUADSPI master and the FPGA as the slave. For communication, all Q...
I try to get the CAN working. But currently I'm not sure what I'm missing.I use the STM32CubeIDE v1.18.0. The boards I use is own hardware with SN65HVD232.The hardware seems to work well. on the picture you see the screenshot from my oscilloscope, CA...
Hi there!I've created a custom STM32F411CEU6 Board with external HSE und LSE. While the HSE works when running my user program, the Bootloader hangs within boot phase (i think).When starting bootloader, BOOT0=1 und BOOT1=0. I powered direcly on VDD, ...
I've read many posts here and on the web, even tried CoPilot, but I could not find how to get the USB controller to send data when the volume keys are pressed.My Host keyboard driver works perfectly, but USBH_LL_GetURBState() is not returning with da...
Hi, I have created a program to send UDP using NetXDuo on a Nucleo-H755ZI.I used the URL below as a reference.Creating a dual IPv6 & IPv4 NetXDuo UDP application for STM32H7 using CubeMX I checked the operation in debug mode and could see that it is...
