In my debugging, I noticed something wierd with this line of code from HAL_SPI_Transmit macro :hspi->Instance->DR = *((uint16_t *)hspi->pTxBuffPtr);pTxBuffPtr being the Transmit Buffer which, in my case, is txBuff[1] the first element of a one-elemen...
Hi,i am using STM32F334C6T.i try to set my PWM as Center Aligned mode and generate interrupt at counter overflow. my code as below.whatever i do in my code, i can not take just one interrupt which is counter overflow. everytime it generates two times...
Hi ST Community,I am using the RTC on the STM32l100RBT6 µC to display the date and time every hour. It is battery powered and therefore at some point i would have to change the batteries, therefore, the µC will lose power. I have thought of using the...
Hello all,I am trying to get started with a STM32DISCO board, like described here:https://www.st.com/en/evaluation-tools/32l476gdiscovery.html#documentationHowever, I can't get it powered.I use the USB USER connector to power it with my laptop.SB set...
Hello,I'm learning to use the SPI module. I'm using an STM32F446RET development board. I want to configure the SPI1 module and send some message 'out into the world'(this means I only have one master devices which sends some bytes and no slave to rec...
The blocking version (HAL_I2C_Mem_Write) works nicely, now I'm trying to use HAL_I2C_Mem_Write_DMA. Here are the settings as given in the configuration tool.The resulting code generated by the configurator (I removed some comments for brevity):static...
I'm using SPI to output a signal for addressable RGB LEDs, as described here. https://innomatic.home.blog/2018/12/24/ws2812sk6812-control-with-spi-and-dma/Since this signal requires only the MOSI pin, it would be great to be able to use the CLK pin f...
Hello I am trying to use STM32H743ZI (NUCLEO-H743ZI2) for classic CAN but I am totally confuse how to set the configuration. I am using 480HMz with 8MHZ(HSE) for CAN.Please advice me how to set the FDCAN for classic CAN.I attach the screenshot of Cu...
Hi, ive been trying to understand how to program arm processors and I come from Arduino, but I never understood where the instructions that a machine understands come from, where are they all listen?
Hi, i would like to understand how to program arm processors in general but i need an in depth explanation or tutorial to show m ehow to find the commands or letter combinations( words) that make the MCU do something. if i were to compare written cod...
