Hello everyone! I want to use some MOSFETS to individually power up/down sensors on a PCB. Here's the schematics : The MOSFET is a DMG1012T-7 (N-Channel) and here's it's datasheet : https://www.lcsc.com/datasheet/lcsc_datasheet_1809050424_Diodes-Inc...
I'm working on a project using the STM32H563RIT6 microcontroller where I need to receive data over UART using DMA with idle line detection. The data is sent from a Python script using 'pyserial'. My setup is as follows: typedef enum{ IDLE, SE...
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...
