removing chip cause unexplainable artifact.
I have a st chip (HT35) with the STM32H735G-DK Discovery Kit. Projects was complete and running fine. We then had to remove the OCTO SPI nor flash chip because we need access to Pe2. but after removing the chip the app froze after MX_TIM4_Init(). The...
Stop flag is not generated with STM32H743BI manually written i2c driver.
Hello, I am trying to write manual I2C driver for STM32H743BI controller. Here system clock is configured for 200MHz and APB1 clock for 50MHz. Below is my initialization code. While testing stop flag and TXIS flag is not set after setting CR2 registe...

Issues using HAL_UARTEx_ReceiveToIdle_DMA(...) and HAL_UARTEx_RxEventCallback(...)
Finally I used the HAL_UARTEx_ReceiveToIdle_DMA(...) function and the associated HAL_UARTEx_RxEventCallback(...) Interruptcallback. It works nice now, but I had some issues, which have been not so easy to explore. So I want to share them here. Maybe,...
STM32L4 - SMBus and Melexis MLX90614
Posted on May 23, 2018 at 17:49Hello,I'm trying to read temperature values from a Melexis MLX90614 sensor with SMBus but something seems to be wrong.I used the HAL_SMBUS_IsDeviceReady to see if I can connect to the sensor and I can.#define MLX90614_...
Resolved! SDMMC DATA_TIMEOUT occurs when bus is idle
I'm using an STM32F779 on a known working custom board connected to an EMMC chip (8 wide). I'm using the SDMMC2 peripheral with a DMA channel for Rx as well as Tx and the SDMMC interrupt enabled. My application has two modes, in the first I log data ...
