recently I bought some new version (disc1) these start working by connecting USB,but they don't start by 5v external supply without USB connection to PC,I have to connect USB connection to PC and external 5v to proper pin then it starts working , now...
Hi.I downloaded some IWDG example code from Keil because I will use the IWDG-feature of my STM32F107. Configurations/init are located in this procedure://__inline static void stm32_IwdgSetup (void) { static void stm32_IwdgSetup (void) { RCC->...
I'm feeling really stupid about this. We were unable to debug in our circuit, so to check, we have a standalone STM32L021D4Px, mounted to a solderless breadboard. 3.3V is connected to Pin 14, ground to pins 9 and 1, NRST to pin 4, SWDIO to pin 13 and...
I successfully write to FLASH but when I try to read I get 0.First I read some data from keyboard to initialize "inter" variable.Then I store it in FLASH, but I can't read it.Here is what I've added to linker .ld file:/* Specify the memory areas */ M...
Hi I am a newbie to ST microcontrollers.I want to connect a simple I2C slave device to my NUCLEO-L152RE board. I also used CUBEMX to configure the I2C and generated the code.Does anyone know a simple step by step tutorial for the communication itself...
Hi,Here is the code from CubeMX generated BSP module for hts221 sensor./** * @brief Read generic device register * * @param hts221_ctx_t* ctx: read / write interface definitions * @param uint8_t reg: register to read * @param uint8_t* d...
Hello, Although in the X-NUCLEO-IHM02A1 datasheet specify that has been tested only with NUCLEO-F401RE, NUCLEO-F302R8 and NUCLEO-F072RB, I would like to know if anybody has tested it with a "NUCLEO-144 - F767Z". Could I suppose that the 2 axis extens...
Hello,I dont find a graphic "consumption versus frequency" to have an idea of the slope.I am looking for different modes like run, sleep, stop and standby.Thanks for help,
I am using Stm32F411RCT chip and using BMP280 pressure sensor * 2 ea and hdc1080 * 1ea. I made the code for three sensors to act as a polling.however, in order to reduce the amount of time that data is read and written, I am changing that function...
I'm using stm32h753-eval, when I use LTDC demo, if i use BSP_LCD_Clear(LCD_COLOR_WHITE) , the program will crash. I need help, thank you very much
