spi protocol

I am using MG32F157VCT6 by Megawin for testing SPI based ethernet. The data is not transferring to SPI->DR (data register). This issue is happening even in the template example provided by Megawin. I have cross-verified all the steps for initializing and setting up the SPI. Need a solution. The...

Hello All, I am very new to embedded environment, so please bear with me. I am trying to read the values at all 4 channels of my ADC (ADS131M04EVM) using the EK-TM4C129EXL board. I am trying to do this over SPI. I found some work from Texas Instruments here...

Hello, I want to communicate with the STM32F4 Discovery card and the PLC Stamp Mini module via SPI. This module has a QCA7000 chip inside. I selected the SPI2 channel as SPI mode 3 (CPHA = 1 , CPOL = 1) and the Chip Select pin as PE4. I want to send the 0X1A00 data and embed it as 0xAA55 in...
