Posted on February 11, 2018 at 15:00Hello everyone. I have encountered problem with USART1 on STM32F446RE. It seems it doesn't work for me. I have used multiple times USART2 and it works as it should, but USART1 with same configurations just refuse ...
Posted on February 11, 2018 at 08:07Hi, I'm interested in better understanding how SDRAM works with the on the STM32F4 Discovery development boards. For example, I have an STM32F429-Discovery. It has 64-Mbit SDRAM on the board.I've closely examine...
Posted on February 08, 2018 at 11:43Hi,for a new project I have to transfer data from a SD card to a serial line SDI (1 GPIO line). The data has to be synchronized with a 20 Mhz clock CK. At certain times , controlled by an external encoder signal, ...
Posted on February 10, 2018 at 11:39Hi all,Just wanted to check with the collective wisdom on this forum. I'm planning to do 3-channel ADC periodic sampling at 10kHz sampling rate. After reading up on the internet resources, two ways appeared to be ...
Posted on February 10, 2018 at 20:49 Hey everyone, I've got a small issue. I've got a Dma that fills a buffer(Double buffer so 2 actually) with data at every rising clock edge. I only want this clock to trigger the DMA 192 times until a reset s...
Posted on February 10, 2018 at 19:56How do I calculate the SPI baudrate in nucleo STM32F103RB?In reference manual it says, Bits 5:3 BR[2:0]: Baud rate control000: fPCLK/2001: fPCLK/4010: fPCLK/8011: fPCLK/16100: fPCLK/32101: fPCLK/64110: fPCLK/12811...
Posted on February 10, 2018 at 18:38Hello,I've tried accessing the MOOCs courses, I got a confirmation email about my registrations but I never received log-in details after registering for this. Are you still running this course? If so, how do I ge...
Posted on February 08, 2018 at 15:49 Hey everyone, I'm using a STM32f722ZE. I wanted to know if I allocate two 32KB buffers. One being in SRAM1 and the other in DTCM, With a double buffer DMA2, can the CPU and DMA run in parallel? To my underst...
Posted on February 09, 2018 at 14:52STM32F4xx HAL drivers V1.7.3 / 22-December-2017I get some data by HAL_I2C_Master_Receive_DMA() and HAL_I2C_Mem_Read_DMA()I found that a wrong Slave address could be sent when using the HAL_I2C_Mem_Read_DMA() due t...
