Hi,there.I am using DAC60508 with my STM32F7，60508 is 12 bits precision，and with 24 bits command-length，SPI interface. After initialize the SPI，I send 3 bytes separately，and I use a oscilloscope to check the wave of SCL�?SDI�?CS，its seems right，but i...
My main goto board ATM has been an Arduino Due as it has heaps of pins, 3.3v, 32 bit , 96K or SRAM, 512K of flash and easy to program straight from Visual Studio.One thing I hate about it is all they all seem to ship with female header pins and the l...
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...
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 ...
