Has anyone tried the X2 chips yet?

I just ordered a couple 28X2 chips for my porch gardening project, and the changes they listed in the info was sort of confusing.

I'm just wondering if any of you guys out there have tried them yet, and have any comments/gripes/tips/tricks about the newer chips.

I really wanted to try out the 28X2 module they made to compete with the Basic stamp, but I'm poor.

I tried them! They’ve got

I tried them! They’ve got some cool featured you should check out on the manual, i can only list a few here:

-3 interrupts

-advanced serial communications : this last thing is quite useful, you basically can receive serial data via the hardware serial pin on the background ( data gets stored in a temporary location (scratchpad)). Once something is received an interrupt can tell you this happened.

-higer speeds: up to 64MHz with the 3volts versions for a total of about 16 000 instructions per sec.

-every pin can be set to output/input, they’re not “fixed” anymore

-other things i don’t remember…

overall, i think they’re great, but this is just a personal idea from a user who deals very much with serial communication (that’s why i especially like them) and who cares much about speed.

**I havent used any X2 chips,**<br>I havent used any X2 chips, being an AVR/Arduino guy myself, but Im really interested to hear about this porch gardening project you are talking about because Im planning something similar by the sounds of it. Have you got any info about the project up yet Zanthess?

Yes, but I also considered
Yes, but I also considered how it would be nice to have info on the new X2 chips in the picaxe forum.

Cool thanks!I do like the

Cool thanks!

I do like the idea of more than one interrupt, but I haven’t really messed with serial communications, except for programming the proc and then debugging it.

It’s just a simplified

It’s just a simplified PICAXE version of the Garduino in the current issue of Make. Basically I’ll have it run a pump from a bucket (no water source on the porch) when the soil gets too dry. It’ll sense the soil dryness with two nails put in the soil and measuring the voltage drop between the two. I’m just waiting for the new chips to come in the mail, and then I’ll show pics of the project :slight_smile:
