Suggestion for a first 18 series PIC for use Flowcode/PPP

Hi Guys,
I was thinking of trying out an 18 series PIC using the HP-488 board and mainly using Flowcode.
Any suggestions of a chip that is fully supported and preferably has a fast AtoD and plenty of memory?
thanks,

Most of the 18F devices will be acceptable. Just make sure that they are compatible with PPP. Some of the devices listed in Flowcode are not supported by PPP. You can see the PPP supported devices by selecting expert mode and scrolling down the list of chips.
The 18F's that we use frequently here are the 18F4455.
Other 18F devices that have been tested here include
18F2550, 18F2439, 18F2410, 18F2515, 18F4680, 18F4550, 18F4410, 18F2585, 18F2520
Your best bet is to decide how much memory you need, how many I/O pins, what features eg. USB, PWM etc. and then find a device that is suitable and available in PPP.

I wouldn't opt for the 4455, or any other USB-enabled chip, unless I sepcifically wanted the USB features. You'll find that other chip ranges are also designed for a particular application (e.g. ECAN, motor control).
The 18Fxx10 chips probably have the fewest bells and whistles, but are still pretty powerful compared with the 16F chips. The 4610 has 64kB of program memory and loads of RAM. I'm not sure if any 18F chip has particularly fast ADCs, though.
