Posted on February 12, 2018 at 08:18CDC has 3 endpoints (IN, OUT and Interrupt). I have no problem with sending messages via IN and OUT (bulks), but there is a problem when I try use interrupt endpoint (0x82). I created similar method to USBD_CDC_T...
Posted on August 04, 2016 at 17:11Timer3 runs 2x faster than expectedI know what many readers are thinking but read onI set my STM32F746 (DISCOVERY PCB) for SysClk=216 MHzAHB Prescaler set to �1 thus HCLK = 216 MHzAPB1 prescaler set to �4 thus PCLK1...
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...
