Dear community,I've been playing with the STM32L4R9I-Eval board and it seems that I can't drive the PG9 pin.My plan is to use the UART1 with the following pins:PB7 (rx) PG9 (tx).I checked the documentation and to use PG9 you have to:Remove R236Open S...
Hi,I am facing an odd situation when I use HAL_Delay. In most of the functions I have it works well, but in some functions the program stays in this loop forever:while((HAL_GetTick() - tickstart) < wait) {}When I debug, the difference between two val...
What is the maximum frequency for SDMMC module when 4-bit mode is used??
When the boot mode activated in STM32F427VIT6 ( BOOT0 pin to HIGH level) , the pin PE13 in strong HIGH state (really 3.3V). Why? The PE13 pin goes to LOW level just if i begin download firmware by UART bootloader

On STM32F105 chip, i need to output a pwm, then adc caputure the voltage on pwm high stable level.So i try to set tim1 ch1 to pwm out, and then set tim1 ch2 as compare output wih no pwm to trigger adc capture with DMA. (CC2<CC1)Eventrually, i cannot ...
Are there any example that uses USART as SPI ? Currently I am using stm32g071kbt6 mcu for a project and i have to use USART peripheral as SPI. Other SPI peripherals on use. I found a few presentation about USART that says USART can be use as SPI and ...
I am working with a dual core processor for the first time & am wondering if i need to use a semaphore to block one processor while the other reads a peripheral register?In my application the M4 is being used as a slave for some concurrent processing...
Hello, I have stm32f4disc and baseboard, ov 9655 camera module, lcd screen. I want to make a camera. Who has guides or tutorials that can help me. Thanks
I am attempting to use the DMA to auto-load PWM values for a motor control application. An example very similar to what I want to do is given in the RM0090, section 17.4.20 (for STM32F427). However, I'm missing some detail and can't get the DMA to tr...
