SSPSR is the shift register used for shifting data in or out. Reading character data from the Display Memory, when in 16-bit Operation Mode, is a 24-bit operation (8-bit address + 16-bit data). The master device originates the frame for reading and writing. The following code demonstrate, how to write a program to use SPI (serial peripheral interface) in slave mode. All gists Back to GitHub. Created Sep 21, 2012. At each pulse, data will be sent and received. The master is the one that sends the clock pulses. I tried treating eeprom as a character file in C, but the obtained data are incoherent (I did a test in bare-metal code and the SPI device works), maybe because I don't know how data has to be send, Could somebody explain me with a piece of code, how should I read/write to SPI EEPROM?. LPC1768: SPI Programming . What project(s) will these Maxim parts be used in?
