I'm using I-CUBE-LRWAN but i have a problem with the wakeup pin (PA0): i can't "wake up" the micro from low power mode with the pin PA0 (WKUP1) of STM32L072CZY.At PA0 I put a pull-down and a button connected to 3V3 to generate a rising edge.I tried t...
Hello,I have F746 discovery board and i want to play a video file stored in SD card. I have successfully able to do file access(txt file) with sd card and file system. to play a video file what are the software modules i have to integrate into my pro...
I am working with the STM32F405-microcontroller and I'm writing my code inside Eclipse (NOT System Workbench) and I'm compiling with GCC and I am debugging using GDB OpenOCD Debugging. My project only has a debug-configuration, it does not have a rel...
Hello,I do some SPI communication, which in general works fine, now I want to get an interrupt at the end of transmission. I use only TxFifo, so TSIZE is left 0. It works fine to load some data into TxFifo via TXDR. Now I enabled SPI interrupt and se...
I have setup the spi connection, and i'm testing it with a logic analyzer.It all works great. BUT, the Transfer half complete interrupts occurs before any data is transferred when i use;(HAL_SPI_TransmitReceive_DMA(&SpiHandle, (uint8_t*)aTxBuffer, (u...
For the spi mode CPOL = 1 and CPHA =1 does the master(stm32f103 controller) receives data on MISO line at the rising edge and also sends data on the MOSI line at the rising edge? Similarly for the spi mode CPOL =0 and CPHA = 0 does same happen as fo...
I am trying to modify the example given for neucleo - LP14R5ZI and port for my custom board.User button in example is similar to PA0 in my codeand similarly for LEDThe device does not go into shutdown mode. I have attached main.c of my modified code
Any example or link to STM32F4 Discovery for ranging an ultrasonic sensor in real time with freeRTOS
