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...
Using an STM32H757-EVAL (don't use CM4) with CubeMX. Configured my ADC1 as follows:DMA is:Start the process as follows (both calls return HAL_OK):I allow the code to run for 10 seconds and break. The m_hv_status_values buffer still has the initial va...
hello,Which command is valid to do this? I see --skipErase, I have also seen --ske, or ske as possible commands to use. What is the syntax for this command? I dont see a reference in the manual...Please help thanks in advance.
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,...
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_...
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 ...
I have a custom board with the l452cc controller. I am trying to run an sd card with fatfs through spi. I have generated cubemx fatfs files, but there is no interface layer for spi to fatfs. Are there some examples I can reference off of, or what is ...
Hi I'm new to using STM Microcontrollers and I have the Discovery board as my development board, I have used Arduino religiously and thought I should learn something new.I have learnt how to modify data registers, for example, turn the 4 LEDs on and ...
I am having a very difficult time trying to read the file directory using the code I got from the web. I am able to get most SD card functions to work and I actually get the read directory function to work the first time but it only reads 6 of the 1...
