I guess your not experienced with C programming then, and of course you<br>
wern't up to speed in the workshop to get help with this part because of<br>
your laptop problems.<br>
<br>
The port setup code goes inside the main() function.<br>
<br>
I have added the completed C code to the downloads on the meetings page<br>
on the website, you can see what it is meant to look like.<br>

i have been investigating bootloaders for use with the 12f1840 and other<br>
chips. It looks entirely feasible to lose just 100 - 300 words (of the<br>
4K word) program memory to a bootloader, which will allow people to<br>
re-program their devices at will without needing a dedicated programmer<br>
device, just using the usb-serial port devices we were using.<br>
<br>
So i am looking to put together another workshop for the near future,<br>
which will utilise a bootloader, talk through the serial port, and<br>
perhaps play with analog inputs.<br>
<br>
Would people be interested if i also offered the chance to keep the kit<br>
of parts after the workshop for cost ?<br>
