Documentation indicates the 18X part has 9 outputs.

I am looking for 9 digital outputs but can only see 8

How do i get to use the 9th?

Thanks

The 9th output is the serial output (TX) channel. It can be used to send serial data (use the "sertxd" command for that) or even - with a small hack - as a standard output pin (there is a poke command, this was discussed some time ago on this webboard. Hippy will have more details).

18X has fixed in/out assignments so you cant change it, it has 8ouputs (9 with serout), its probally a error where you read 9.

Their product description onsite is
PICAXE-18X microcontroller chip. Supports 5 inputs and 8 outputs. Extended features include 8x memory and i2c support.

Thanks very much for the repsonses - I thought that might be the answer,

The 'Which Chip' Matrix simply states 9 outputs but I could not find anywhere a clarification of the 9th output in any Rev-Ed documentation.
I am looking for 9 outputs so i guess I'll have to get more creative or move tothe 28 series.

Thanks again
