PIC24FJ128GA010 and spi
PostPosted: Tue Dec 22, 2009 11:47 pm     Reply with quote
Hi all
I am now working on spi and pic24fj128ga010.

I have run the sample code in mplab C30 compiler but now I want to program for explorer 16 board in CCS PIC C.

In Explorer 16 board spi is connected to eeprom.
Now how to program for that eeprom to read and write data?

Actually I am new to world of PIC and doing everything on my own.
Thats why I am facing alot of problems.

For a SPI flash replacing the original EEPROM , I used the below settings on an Explorer16 board

Code:
#define SPI_CLK_DIV_2    0x001B
#define SPI_CKE          0x0100
#define SPI_CKP          0x0040
#define SPI_MODE_0 (SPI_CKE)
#define SPI_MODE_1 (0)
#define SPI_MODE_2 (SPI_CKP | SPI_CKE)
#define SPI_MODE_3 (SPI_CKP)

setup_spi2(SPI_MASTER | SPI_MODE_0 |SPI_CLK_DIV_2);


They should work with 25LC256 as well. As discussed in previous threads, it's the most simple method to use spi_read() for both read and write with PIC24.

I am new to world of PIC.
I want some good tutorials on using spi and other peripherals in PIC by using CCS C compiler.

Can anyone tell me about some good website for it ?
