I'm using I2C2 engine of the STM32F767ZI MCU on PF0 & PF1 pins as master to communicate with 4 slaves at 75khz. The operation is not using Interrupt on tx/rx or DMA and with FreeRTOS environmentSCL and SDA are pulled up on board with 4.99K.The pollin...
Hello,I am using ADC1 on STM32U5 to sample two channels periodically using the DMA and a TIM6 trigger. I am doing this in bulb mode since I would like for the ADC capacitor to charge for the entire duration.I had thought that the ADC would sample th...
Hello, I have had a problem and it is that I make a simple program, in this case the blinking of the led of the "NUCLEO-F401RE" board and I use the gpio that comes by default. The point is that when I try to debug main.c, another file is opened (whic...
Is it possible to set transfer from sdram to SPI. I have set all necessary MPU regions and FMC is configured properly. When I use this with LTDC, it works fine.(not using standard DMA for that).But, when I try to send from 0xC0000000 to SPI, DMA1.str...
Hi Experts,I'm working with the MCU "STM32F427VIT6" and the flash memory "GD25B16ETIGR" and I have a problem when I try to read the "read status register (05h)" I get 0xFF. However I know I have no problem on the SPI connection because I can read the...
Hi, I am using stm32f769Ni evk for a project. Here I am interfacing stm32 with a wifi module using spi dma . The communication fails during reception with HAL_SPI_ERROR_DMA after /* Enable the Tx DMA Stream/Channel */ if (HAL_OK != HAL_DMA_Start_IT(...
Hi,We're building our system based on STM32F407 with AZure Threadx + NetxDUO. One of the scenarios is as below:1) One 250 HZ task is responsible for sampling on 6 sensors connecting to 3 I2C.2) One UDP thread is receiving command from PC with 250HZ.3...
The STM32F446RET6 and STM32F446RCT6 are similar except for Flash size. Is it possible to create a .hex file that programs the RE version that could program both chips using the ST-Link V2?
