I'm using stm32f030f4p6. The system clock frequency is 8mhz. uart1 setting 9600, n, 8.1. I am using the following program code. wotchdog stm32f030f4p6 uart is running smoothly when I send 18 123456123456123456 characters from my computer serial port ...
Hi all, I noticed in the SAI examples for the STM32H7 EVAL board that when selecting 48KHz for the SAI output, the actual output is only ~47.8KHz.Looking at the code, I see the following:/* SAI clock config: PLL2_VCO Input = HSE_VALUE/PLL2M = ...
Hi everyone! I am using STM32F446RE for a project of Tetris with a LEDs matrix (WS2812B). To communicate with my LEDs, I call HAL_TIM_PWM_Start_DMA(&htim2, TIM_CHANNEL_4, (uint32_t*)pixelsBuff, (uint16_t)pixelsBuffSize) every 500 ms. And this works w...
I'll tell you my sad story because of a bad manipulation of the device.Never take a call while you are sketching a project with the adc.Device: STM32F746G Discovery BoardWhat happened? : I fed the ADC3_IN0 pin with a signal of approximately 10V for a...
Hey guys, befor asking my question I want to give you a brief overview of the test case:TestCase: SPI Full DuplexMaster send [0-3](4) bytes and Slave returns received bytes [0-2](3) immediatly. (no register preload in slave)Example:Master <-> Slave0x...
Hi all,Just wondered if anyone had a similar experience with this. Currently i'm storing a devices current state and settings in the EEPROM. This information is accessed and updated at a high frequency during a part of the program. I have experienced...
I have encountered a strange power draw behavior of an STM32L0 device in a battery powered circuit. Using a Nordic power profiler kit, the device draws the nominal 5 uA current after entering Stop mode then seems to "wake-up" and draw 78 mA. The curr...
Hello, I want to implement an I2C slave on the Nucleo board with interrupt functionality. As a master, I have an Arduino ESP8266. The master queries data from the nucleo. Now I'm not so familiar with the STM32 and Nucelo and HAL. Is there a giagram o...
Posted on December 17, 2013 at 05:03Greetings all, I've been playing around with SDIO on an STM32F4 -Discovery card with the Embest Baseboard on it. My goal is to get it to work in polling mode, flow control mode, interrupt mode, and dma mode. This ...
Hey, I try to get timestamp from tamper event when mcu supplied with VBAT, but value oftimestamp still 0, can anyone help me ?
