Having trouble with SERIN command and MAX6675

[emerson]

Hello again. I'm trying to have a 16f630 receive serial data from a MAX6675. I read the SERIN section in the help topic but I still can't understand how to set it up. here are the datasheets for the chips and my code as well:

http://pdf1.alldatasheet.com/datashe...IP/16F630.html

INCLUDE "modedefs.bas"

'Setup MAX6675 - Thermocouple
MAXData	var    porta.5   ' MAXpin7
MAXcs	var    porta.4	' MAXpin6
MAXClock  var    porta.2  ' MAXpin5

MAXResult var word
THC	var word	' degrees Celsius (* power of 10)
THF	var word    'stores degrees F

Main:

  low MAXcs	' select chip
  serin maxdata, N2400,maxclock, [MAXResult\16]	' get data
  high MAXcs	' start new data apture
   
THC= (MAXResult/32) ' Deg. C
THF= (((THC*18)/10)+32) 'Conversion to Deg. F

lcdout $fe, 1
lcdout "Temperature: ", dec THF, "F"] 'display temp. on LCD

pause 20 'give time between read cycles for MAX6675 to work right

goto Main
