I am using STM32L072RB MCU is in while loop of main function. with Timer6(for Blinking and LED every 2sec) and systick timer is running.Now i call function : adc_spi_chip().I am waiting for PA2 pin to become low but i found that waiting for it using ...
Hi!I'm trying to share one UART in both cores of the dual-core STM32H745. I'm using the HAL library.I've achieved to transmit (in polling mode) from the two cores using a semaphore to manage access to the UART.However, I can't receive using interrupt...
Hi,I am trying to assign an address to a pointer the following way:#define FM_P_ADDR 0x0807F800uint64_t * addr = ((uint64_t *)FM_P_ADDR);However, running the line will direct the execution to the Hard Fault Handler routine.What is happening? What ...
Hi,I have designed a keypad with 11 touchkey's. For this I have used TSC group 1,3,4 and 6. As FW i have used the STM32_TouchSensing_Library and I have a problem. All groups are working ok, sensing touch corectlyexcept group 1. This group has the sam...
Suppose I use an oscillator instead of the suggested resonator for LSE. Will that even work, i.e., will the internal RTC continue to function when in battery mode? I assume that I'd have to power both oszillator and STM32 (using Vbat)?
Hi,It seems that in some events the I2C data setup time (Tsu;dat) is not respected by the MCU.Please let me know if I am wrong.I am using the I2C1 of an STM32F745 at 100kHz with the HAL library.The I2C setup was done using the CubeIDE.When using HAL_...
I use the TIM3+DMA function of STM32F103VCT6 to generate PWM. I need to generate a series of adjustable frequencies, adjustable duty ratio and controllable pulse number.Such as 10KHz, 200KHz, 500KHz, 1MHz, 2MHz, 5MHz.I modify the VALUE of TIM's CCR b...
Hi, I've worked a bit on STM32 before (STM32F7 to be more precise), so I have little knowledge about the STM platform. I normally don't need to ask question on forum because Google is a very good professor, but this time I'm not sure to have found en...
Hi everyone! I'm trying to learn how to program microcontrollers with C and stuck with trivial task.I have blue pill, stlink v2 and ssd1306 oled displayI'm trying to enable all pixes on the display via i2c: https://gist.github.com/ksevelyar/5e6c0335a...
I'm working with STM32F405, not sure if I'm asking question in right place, or if it matters... I'm working on a self-test for CRC FLASH (can't use libraries, just basic code). I notice that, for non-optimized code, the generated BIN file matches FLA...
