Hello,I have a custom hardware using STM32H725 board, sometimes(2/10) I am trying to debug the board using ST Link v2 and It is not getting connected and showing me the error to connect if device supports debug authentication enable it.in order to c...
Hello,I am currently evaluating STM32s for use in professional developments.I'm going to substitute them for Microchip's AVR DB family microcontrollers.I still have one point to evaluate: is there an EEPROM built into the STM32s that allows parameter...
Hello,It looks that empty check on STM32G071GB is causing some problems to my boards due to high, low signals on pins. I am trying to omit empty check procedure and program my MCU using st-link by SWD. Is there any procedure for such scenario? When c...
@mƎALLEm @TDK @Andrew Neil Hi! I am trying to drive a 40 pins TFT screen by myself, but it's been a little difficult to achieve this. First -> I did this schematic to connect the screen to my microcontroller: I thought it would work fine, since ...
hello, how can i know the first pin of STM32H750VBT6 chip for proper connection on board
I use NUCLEO-H7S3L8 to evaluate our new solution. I want to use GPIO port P to control a few external components.I add some test code into NUCLEO-H7S3L8\Examples\GPIO\GPIO_IOTggle project, like the below snapped code:__HAL_RCC_GPIOP_CLK_ENABLE(); GPI...
Does the STM32H743XGH6 have a pull-up/pulldown resistor built into the JTAG pin?Is it necessary to add external resistors?We ask this question because the AN4488 application note does not cover this product.
Hello ST experts, i need help about using STM32H747i-discoI'm testing Uart Tx(DMA)-Rx(Interrupt). My goal is 10Mhz uart tx-rx.The problem is that i success 750khz, but fail to Rx when baudrate 1Mhz~10Mhz. I set the disco 480Mhz setting (hw SB setting...
Hello! This is my first post here. I'm currently designing a DIY loop pedal for guitar, which basically records samples of audio and plays them in loop.I'll be using a STM32H743VIT6, embedded on a WeActStudio dev board. The audio CODEC is the PCM3060...
Hello, I'm using an STM32C011J6M6 with the Arduino IDE to register with theST25DV64KC-IE6S3 's EEPROM. I previously used the ATTiny85 and would like to replace it with the STM32C0 to maintain the entire solution with ST components. I made some change...
