SPI controlled registers in peripheral chips question.

Started by Martin Griffith February 29, 2008
Just been handed a possible job that requires a  encoder IC to be set
up via SPI, about 20  r/w 8 bit registers. I'm going to use a 8052
with a  2 line LCD that's memory mapped, just because I have a couple
of boards lying around

I'll add a few buttons, but I was wondering if there is any neat way
of organising the code (in  C ) to play around with the registers
while prototyping ( mucking around, really)

You could write up a little interpreter/debugger to do it. Ed

I was thinking of using the UART and terraterm to show the status of all the registers, in 0/1 and the LCD for some sort of menu martin
