HiI wrote a little CEC application. Unfortunatly communication with other devices didn't work well.I used a logic analyzer to find the problem.The error is in the IRQ function HAL_CEC_IRQHandler:[...] if((reg & CEC_FLAG_TXBR) != RESET) { if (hcec-...
Is it possible to use self-powered STM32F072 as USB peripheral, permanently connected to Raspberry-Pi host on USB?My worry is during recovery from STM32 power reset/ watchdog reset, raspberry-pi getting powereup alone , whether the USB-VCP-CDC will r...
I need a CAN hal example code for stm32f103.
Hi guys i am trying to find alternate function map to AF0,AF1 and so on but i did not find that in datasheet where is that i am using stm32f303re from nucleo-64.
Hello guys, I would like to examine compex codes using FreeRtos, I need to see hard application to better idea
My daily use IDE is Atollic, my board used to have a single 6 pin connector for programming, and everythin worked fine since I can remember.The new hardware guy decided to add another connector to program the MCU (STM32F4), and our new board ended up...
Hi All,We are using STM32L4R5Zi-p nucleo - 144 board for our development activities. We tried to create a UART code using cube mx. But it seems like data is not sending through TX pin. We checked the TDR register of UART and we can see the data going...
With nucleo-f429ZI board, I want to measure the signal fminance in imputCapture (tim3_ch1) with dma + dac to generate a known frequency signal. but :When doing rcc settings like this, imputCapture calculates the correct frequency. On the dma + dac si...
Posted on August 20, 2013 at 09:54Hello,I need to design a 20 pin capacitive touch board and I am planning to add a driven shield. But it seems that there is no detailed design guidelines about the topic. I could use some help at least about key sub...
I am working on STM32F4-Discovery board with STM32F412ZG. Trying to work CAN communication between MCU and PC with the help of kvaser canking tool(SJW=1, bus speed=125 kbps). I got success in transmitting data to PC successfully and I am getting corr...
