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 folks,I'm sampling 8 microphones using 4xI2S peripherals using DMA and a double buffer, which I then use to write to 4xWAV/PCM files on a USB drive and am getting buffer overruns intermittently!I believe I've narrowed it down to the FatFS file wr...
There is a bug in stm32f7xx_hal_i2c.c!!!!!!!!!!!static HAL_StatusTypeDef I2C_Disable_IRQ(I2C_HandleTypeDef *hi2c, uint16_t InterruptRequest) { uint32_t tmpisr = 0U; if ((InterruptRequest & I2C_XFER_TX_IT) == I2C_XFER_TX_IT) { /* Disable TC an...
Hello,When using cmsis_os (with freeRTOS), osTimerCreate , does it utilize the real HW timers, or only use the OS timer ? Thank you,ranran
Hello,I have a problem with VCP on NUCLEO with STM32F767. There is no demo for STM32F7 and I have no idea how to start. My idea is to use USB periphery of STM32F767 for communication via VCP. Can you help me, please how to start or where I can find s...
Hi,I am using STM32F405 micro-controller and interfacing enc28j60. The enc28j60 communicates on SPI, so I utilized SPI1 peripheral for that purpose using following pins:-PA4 - CSPA5 - SCKPA6 - MISOPA7 - MOSINow SPI1 works perfectly well with micro-co...
Hello,I am considering to develop a small secondary boot loader for STM32F030xx.My idea is this BL checks the CRC of the application image and jumps to it if CRC matches. A second fallback image would be jumped to should the primary one be invalid (e...
Hello,I have some strange behaviour:After adding external flash configuration to my application, the Ethernet stopped working (no ping).I validated that the following added code is responsible for this failure, but I don't understand why these config...
I am using STM32F756 Eval board and trying ADC+DMA example.Example, is about one ADC conversion and the data is stored in variable using DMA.I am looking out for changes to be done in the configuration such that,After I start ADC conversion, I must ...
Hi,I am writing a 16bit register 0x3f of i2c device connected at 0x09. After write, if I read the value of 0x3f register it is always '0'. I2C communication is working fine on device.Below is a code.#include "main.h" #define I2C_ADDRESS 0x09<<...
