Resolved! when exactly void HAL_I2C_ErrorCallback(I2C_HandleTypeDef *hi2c) will be triggered and i have enabled the error interrupt in IOC setting but i could not understand occasion of this happening .
HAL_I2C_IsDeviceReady is good option to check sensor presence but while i2c sensor working incase of error occurrence will error interrupt will be triggered ?
Is anyone using Rust here , any toughts?
Does it deliver what it promises? (you could helloworld a web page and a microcontroller with no big code difference)Is it worth the hussle of learning it?Is there any real example of a situation where Rust saved the day?
I have UART1 and UART2 configured. I am looking to bridge the two together. UART2 (115200) & UART1 (9600). UART2 (PC VIA USB) and UART1 [DMA, Circular (word)] (Connected to external device UART interface).
Code snippet```while (1) { HAL_UART_Receive_DMA (&huart1, UART1_rxBuffer, 100); HAL_UART_Transmit (&huart2,UART1_rxBuffer,sizeof(UART1_rxBuffer),100)}void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart){ uint8_t UART1_rxBuffer[100]...
Resolved! Software migration from STM32F207IGH (Cortex-M3) to STM32F427IIH6 (Cortex-M4)
STM32F207IGH used in the existing product. We see that we need more Flash & SRAM to include more software features. STM32F427II is having double the size of both Flash & SRAM. What is the process to migrate software to STM32F427II? Micrium RTOS used ...
Noise in accelerometer reading when gyro enabled on LSM6DSR - connected to STM32H745
Hi All,I'm interfacing LSM6DSR IMU with STM32H745 over I2C (1mbps). The accelerometer data looks good and consistent with pretty low noise. However, as soon as I configure the Gyro as well to turn on - the accelerometer has really wild noise.Attached...
How to write doublewords to flash on an STM32F411RE
I could get HAL_FLASH_Program to write WORDS, as soon as I moved to FLASH_TYPEPROGRAM_DOUBLEWORD the last error returned is alwasy PGA | PGS flags in the SR. PGA = alignment, PGS = sequence. I referred to every internet article I could to figure out ...

Resolved! UART DMA Transmitter and receiver issue
i'm using STM32F730 as uart receiver and STM32f0 as uart transmitter baud rate 9600, 8 bit data representation. i'm using DMA with interrupt for the communication. i'm using HAL for programming on IAR workbench. The transmitter is continuously transm...
Hard fault invalid state
I'm trying to inject a simple wrapper around my timer interrput handler written in C - primarily for debug purposes to simplify debugging the state of registers and stack before the C code gets in and messes up the stack and state pushing all the jun...
