Thank You..

Return value works perfectly with the current program itself, I had not observed it properly. The last 13 bits are actually showing the status of the registers, but only if I write to ...

Thank You Experts...
I have changed approach as you suggested by you.
Also I am sending the register value twice which makes it happen.

But reading the register value back from the slave is a pro ...

Thank You for your grateful response.
I have changed the mode to MODE0. Still there are issues with SPI communication.

Need to understand more on how this SPI communication works.
Here in my code ...

Experts,
Please find program below:

#include "E:\EMBEDDED\PICDEM 2 PLUS Projects\SPI_L9942\SPI_L9942.h"

#use spi(MASTER, MODE=1, DO = PIN_C5, DI = PIN_C4, CLK = PIN_C3, baud = ...

Thanks for the great response.

Now there is a fractional 'pause' in the clock between byte #1, and byte #2, as the PIC SPI buffer is reloaded, but because of the synchronous nature this doesn't mat ...

Hello Experts,

I am quite new to SPI with PICs.
Please help me out with the basics of SPI communication.

PIC 16F877A datasheet mentions that SPI is for 8bits.

I want to communicate with L994 ...

PostForum: General CCS C Discussion   Posted: Thu Dec 27, 2012 11:04 am   Subject: gear check using 2 switches
I think switch bouncing and delay is the problem in my code.
Is it possible by using analog inputs?

I have used two DPDT press-release switches to find the gear shift in two wheelers. The idea is to scan the switches at each gear and relatively find the next. So I used a global declaration for integ ...
