Looking for information on 20M

[gengis]

Does the 20 M support advanced commands similar to the 14M?

Where can I find documentation? Something similar to Appendix C of manual #1?

Flooby.

Until something better is found, try post #26 in this thread.

Thanks eclectic

Technical sums it up:
"The 20M supports all the 08M/14M commands with a couple of exceptions:
1) the i/o pins are always fixed so 'let dirs' (dirsc) etc. are not required
2) the 20M does not support pwm/pwmout/hpwm
3) it does additionally support the 'serrcv' command

Apart from this it is very similar to the 14M, supporting all the usual servo, serout, tune, pulsout type commands and with 256 byte capacity, around 80 lines of BASIC code."

For some reason searching the archives (on "20M"!) didn't get any matches

3) it does additionally support the 'serrcv' command

I think you mean SERRXD- the converse of classic SERTXD- which allows data to be received from the PC back down the programming cable. 28 & 40 X1/X2 PICAXEs also support this.

serrcv is a direct quote from Technical's post.

So it is for Technical to clarify

 

[Technical]

typo, serrcv was the original 'internal development name' for (what became) serrxd, and so the staff sometimes forget and call it that!

Part 2 of the manual shows all 20M supported commands, just look at the graphics on the left beside each command.

Flooby,

When doing a forum search and you get no results, try adding an asterisk at the end as a wild card.

So instead of 20M use 20M*

I found the same thing when looing for threads about i2c comms.
i2c gives no results but i2c* found lots.
