14M readadc

[markhommer]

I am using a picaxe 14M. I am needing two adc's for my project. I am using the ADC 4 (on physical leg 3) and this one is working. But I have tried using ADC 0 (on physical leg 7) but I get the following compile error message "Error pin0 cannot be used with this command", where my command is readadc 0, b4.

I have tried to use the "let dirsc" command to redefine the portc pins for adc's but I get the following message "Error: let dirsc command not supported in this mode!".

I am using program editor ver 5.1.5 and I have 14M selected as the picaxe mode in the options.

Does anyone know where I am going wrong with this readadc command? Or are there other pins that can be used as ADC's.

Thanks in advance.

Mark.

Copy the line below to the top of your code -
#picaxe 14m

Should work ???, have a look at Picaxe manual 1 Appendix C for other analog inputs on pins 8, 9 & 10

Flashes led on output 5 while reading ADC pin0

#picaxe 14m
do
    toggle 5
    pause 500
    readadc 0,b0
    debug
loop

Sets all portc as inputs and C2(output5) as output

#picaxe 14m
let dirsc = %00000100
do
    toggle 5
    pause 500
    readadc 1,b0
    debug
loop

Checked both of these in the 14M and they worked ok

Thanks for the quick replies.
I learned something...
The readadc 0,b0 & let dirsc commands only work when you have Enhanced compiler selected. I had the Standard compiler selected.

Thanks again.
