I have two external clocks connected to TIM1 and TIM2 of the stm32f746 (disco). I'm basically trying to implement a frequency counter of the clock connected to TIM2. The TIM1 clock will act as window (driven by a TCXO). In my test setup the TIM2 cloc...
Hi,I have a NUCLEO-F429ZI board and am trying to get ADC1 to convert one channel (channel 3) when triggered by TIM2 (every second).As I don't have an oscilloscope I wanted to measure the conversion time - to make sure everything is configured correct...
Hello,I am trying to communicate with the UART bootloader (NUCLEO64 F446E) using a second board (NUCLEO32 L432KC).I am using USART1 (PA_9, PA_10), on which I am trying to send the 0x7F frame to activate UART bootloader (after having activated bootloa...
We generated ADC code for STM32H755 using CubeMx. ADC1 is setup a single channel, one shot conversion. We are using internal Vref at 2.5V. We are reading 0.9V as a test and the DR keeps changing randomly. What are we doing wrong? Thanks!// adc.c gene...
There isn't any PC14 PC15. Is it really inaxessible on this MCU and I'm have to find suitable HSE crystal in order to get high-presition RTC?
Hi guys, I read reference manual for STM32H745/755, where is mentioned that the both CPUs are after reset running on the same clock frequency, because they shared the same clock source and the prescalers are after reset in default state (no division ...
Hello All,I am using custom board using stm32f446ret7 controller. I am creating a sample project using CUBEMX for this stm32f446re controller and trying to flash using st-link/v2. But has got one warning as below. Can anyone help in understanding whe...
I have configured STM32l496RG as slave and am trying to send data from my STM32L496RG slave to ESP32 master upon reception of data into buffer array. I am trying to echo the same data back to the master. My master ESP32 transmits data 'hello' and r...
I created a project using the CubeMX software, as the basis for a music playing device.I then used the SD disk io dma rtos driver from the wav player/recorder as the cube generated code is broken.Can I put a project on github using the above code?I'v...
