To fix this, we need to explicitly switch pins PA5-PA7 to the SPI mode. Home » CCS C Compilers » Technical Information » C Language Features » #USE SPI () #USE SPI () Some of CCS's most powerful libraries have been the RS-232 and I 2 C libraries, which give users the flexibility of using multiple RS-232 and I 2 C ports at once using any set of general purpose I/O pins, and not tying the user to only using the hardware peripheral. Timer-2 is used to provide clock to SPI module, so you can not use Timer-2 for any other purpose if you are using SPI module. This means we can have a virtually unlimited number of devices on the same SPI bus. 123-456-7890 1: Takt ist invertiert: in Ruhe HIGH, ein Wechsel auf LOW zählt als steigende Taktflanke CPHA (Clock Phase) 1.

Compared to some peripheral devices like sensors, which can only run in slave mode, the SPI of the AVR can be configured for both master and slave mode. SPI exchanges the contents of the SPDR of master and slave. Introduction This Application Note provides to customers C and Assembler program examples for SPI. Simultaneously, a byte from a slave shifts into the SPI-data register. Ju_axib . Typically there are three lines common to all the devices: 1. Timely updates on new products, reference designs, design tools, technical articles and design resources. The programming is similar to the Arduino code. In this tutorial we are going to discuss the SPI ( Serial Peripheral Interface). 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?.
