Hi ST community,I am interrested in using the STM32F767-Nucleo board for SPI communication. My system is as follows. I have one STM32F767-Nucleo board which is my SPI slave and a Raspberry Pi which acts as SPI master device. The Raspi should read dat...
Hello. I am trying to read ReRAM( FUJITSU: MB85AS4MT) by using HAL_SPI_Receive().But the LSB is recognized as 0 even the reply from ReRAM is returning 1 to LSB. (ex: '11111111' is recognized as '11111110', or '01010101''' is recognised '01010100...
I want to programme STM32 MCU connected to ESP8266 using USART now i want to programme these STM32 MCU using laptop at remote place connected to internet.how can i make this possible ?
do the USART ports be configured to support HDLC/SDLC protocol ?
There are two identical controllers with STM32F107VCT6. One of them is programmed, and another one is not. Memory protection is disabled. I haven't the original program project, and the task is to read and save program from the first controller and d...
Hi, I have imported the example project TX_CMSIS_Wrapper and I wanted to integrate SPI5 with it. After initialising SPI5 I could not see any clock signal generated. I am using STM32H747-DISCO development board. void MX_SPI5_Init(void){hspi5.Instance...
I'm trying to use the internal reference voltage of 2.048V in my application, since I'm powering the microcontroller with 2.8V. But when I select the reference source and enable the VRefBuff with this lines: HAL_SYSCFG_VREFBUF_VoltageScalingConfig(S...
HI , I am having an issue with STM32F205 controller CAN rx message reception. We used cubemx to generate the CAN driver at the baud rate of 250kbps. we want to receive CAN messages around 1100 messages per second. but we are missing CAN frames above...
I have enabled DMA for usart2 in pins PD5 and PD6 and I have attached my main file. I have tried uart transfer by polling mode and interrupt mode both are working fine. But when I try for DMA mode the data is not transferring .I don't know where I ha...
I am using an STM32 MCU. When I use the HAL_Delay function with a parameter of 1000 for example, I see that the delay is shorter than it should be. I have checked that HAL_IncTick(), but it works correctly and it is placed inside the SysTick_Handler....
