Hi.In AN5593, How to use the GPDMA for STM32 MCUs, on page 31, it says:"For some application needs, a timer request to GPDMA can be used to initiate a data transfer not involving timerregisters read/write, but other memory-mapped location, like for m...
I am starting to experiment with stm32f411vet6 (discovery), I have passion for STM32, looking forward to learn and help.When I turn on UART 6 and test, the default pins are PA9 and PA10, however it doesn't work (some error characters like question ma...
Hello, I'm trying to measure cyclic temperature on a dedicated task with FreeRTOS. For that, I set my ADC with DMA, based on the example provided here (at DMA section: https://wiki.st.com/stm32mcu/wiki/Getting_started_with_ADC#Configure_DMA) For ...
I can't get TIM15 or TIM17 to work on a Nucleo-F302R8 board. If I examine the peripheral memory where TIM15 (0x40014000) and TIM17 (0x40014800) should be, I always read back all zeros.For example, using gdb I write to the timer's ARR register and the...
Hi,I am using the continuous mode of the ADC to continuously sample a channel and transfer the data by DMA. I have set the ADC frequency to 32 Mhz , and the sampling CLK to 3.5 CLK. According to the manual , the whole sampling conversion time should ...
Hi everyone, I’m working with the STM32H747I-DISCO board and its onboard QSPI flash (Micron MT25QL512ABB). I’m encountering a frustrating issue: Problem: Writes to even addresses (e.g., 0x90000000, 0x90000002) work perfectly. Writes to odd addr...
Hello everyone,I'm encountering an issue with a circuit that incorporates an STM32F103R8T6 microcontroller. In my design, the MCU's VDD domain is powered by a battery, while an external supply is used for the analog reference (VDDA). When the circuit...
Hi,I am laying out aboard with STM32L073. I would like to add a debug header and a programming header. Do you know which pins i should connect these headers to? I see that PA13 and PA14 are involved in debugging, but which other pins do i also need...
Hello, I am using the STM32F407IET in one of my projects and I have timer 1 set us as follows below currently my channel 1 is used to record the positive rises on a incoming pulse signal and what I want to do is use the gated mode to be able to tell ...
Dear All,I am a student working on a project where I'm trying to use an STM32U585 microcontroller to drive an AMOLED display with an ICNA3306 driver IC via the OCTOSPI interface. I'm quite new to this, and I've been struggling to get the device ID fr...
