I am trying to use ADC with DMA on STM32H743XI. I set up ADC1 IN7~IN9 and use three uint16_t to store their converted values. I use DMA2 Stream 0 to transfer data. CPU ICache and DCache as well as MPU are disabled. ADC Clock Mux is set to PLL2P 50MHz...
Dear, I am trying to run the CAN Communication in STM32F407 discovery board, In CAN_INIT I have made controller state to Ready after that I have changed the controller state from ready to LISTENING in CAN_START function, but when I am trying to exe...
Hello,I tried to set a capture/compare register to a value beyond that of the auto-reload register, and the timer I used (TIM8) behaved as if the value had not been written. Reading back gives the expected value though. I haven't dug more but I'm cur...
[Not a bug report, explanation below, first post kept for context]I'm writing a USB host library for the STM32H743 rev V. Bits PENA and PENCHNG of register OTG_HPRT represent Port enable and Port enable/disable change. Port enable is supposed to be a...
I'm using an STM32F103C8 and I have an array of unit8_t that I want to save to a particular position in flash memory, where such position is specified at compile/link time. Eg. suppose the application resides in flash memory from position 0x08000000 ...
Hello, I'm wondering if there is an obvious way to generate a limited set of n pulses from an external trigger?At the moment i'm using TIM8 in one pulse mode with repetition but my problem is that i want the White pulse train to start with the risin...
I saw at least one person elsewhere mention this (but got no answers).On the STM32H503 (LQFP48 pin package)...This configuration:HAL_RCC_MCOConfig(RCC_MCO1, RCC_MCO1SOURCE_HSE, RCC_MCODIV_5);Produces no output on the MCO1 pinbut changing it to this:H...
Hii,I am working with stm32f100 series microcontroller, where I am having issue with NRST pin, I have connected a capacitor of 0.1uF(also tried 10uF) between NRST pin and ground. Microcontroller has an internal pullup. and it is showing 3.3V at the t...
Hi guys,I been working on this project for some time now on my "free time"...but so far without any success.In the first prototype I have assembled all the peripherals(QSPI, eMMC, SDRAM, some I2C and SPI slaves peripherals and DSI display.).Nothing s...
Hi i m working on H732 timer1 as PWM and its working fine, but when I try to implement DMA on timer1, there is no waveform. I enclosed the DMA code below, as I declare an array of 10 PWM duty cycle values..i suspect it's the Timer1 channel1 stream th...
