Posted on February 11, 2018 at 19:03What is Software NSS and Hardware NSS in SPI? Which Nss mode should we select?Do we need to connect the NSS pin (between master and slave) in Software mode?I read the NSS pin management in Reference manual, but I ...
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...
