Could you provide a bare bones code example that would give me a start on this?
I\'ve been unable to make any headway after considerable effort.
SPI is not really a standard, it basically means you have a couple wires that
are a serial interface to the peripheral.
This device falls into a class that might better be done with SHIFTIN
While I can't test it this should be pretty close (I assume that CSpin, CLKpin
and INpin have been #define 'd)
#define SHIFTpreSample ' because data is ready when CS goes low
#include
shiftCounts(0) = 32
IO(CSpin) = 0
shiftin (INpin,CLKpin,0,1) 'read the value
IO(CSpin) = 1
max6675_reading = shiftValues(0)
