yep thought it may have been the lcd option causing this , but i can read the ports directly so see if they are 1 or 0 also the lcd option is output segments , the ports are configured as inputs , both have analog options on them but i believe i have set this correctly for both ports
The only thought i have is that cos the ports F & G are not in the mem bank 0 , then pulsin does read the information correctly and not able to use them ?
but if some one has a chip that has ports that not use mem bank 0 - usually above port E , and pulsin works then that theory is shot , but be nice to know
hears the code relating to the tests and part of the chip config as it relates to port F and G

testing port F at the moment
Code:
' ------- Setup port F Variables ----------
ANSELF = %00000000 ' Set Port F - Digital I/O , 0 = Digital 1 = Analog
TRISF = %11111111 '( ports input)
currently Port G is setup for output ( except G.5 which is always input and config 1 " MCRLR is used for reset and not a digital input pin)
Port G has 6 I/O only
but when confirming test with pulsin
TRISG = %00111111
Code:
' ------- Setup port G Variables ----------
ANSELG = %00000000 ' Set Port G - Digital I/O , 0 = Digital 1 = Analog
TRISG = %00100000 ' setup Port G input=1,output=0 for I/O pins - portG.5 always input ( internal pullup) VPP/MCLR
PORTG = %00100000 ' Clear Outputs
test 1 - test pulsin with a clock source time period of 1ms high pulses applied on each port
Code:
DEFINE OSC 32 ' Timing reference for pause , pauseus commands
DEFINE PULSIN_MAX 5600 ' Maximum counts( clock ticks) allowed before pulsin times out( 5600 ^ 1.25us = 7 ms)
Main:
pulsin PORTF.2,1,Leader
if leader > 0 then
write $A0 , Leader.highbyte ' debug only
write $A1, Leader.Lowbyte 'debug
goto main
Test 2 - read logic level of port and write something to show if it was a 1 or 0 to eeporm
Code:
if PORTF.2 = 1 THEN LEADER = $1234
if PORTF.2 = 0 THEN LEADER = $5678
write $10,Leader.highbyte
write $11,Leader.lowbyte
