To get the full benefit of MMBasic 4.6B (hope that is what its called) is the

PIC32MX170F256B 28 pin PIC the best choice ? Does any other PIC (e.g. the 44 pin version ) offer any extra speed or RAM size ?

Is there a way of telling which version of Basic is on the PIC once you are accessing it ?

I've got loads of questions, such as is there a neat way of downloading or uploading programs into it and out of it ?

I use Linux Ubuntu 14.04 so I've found from the linux 'terminal' this works a treat:-

picocom /dev/ttyUSB0 -b 38400 -l (lower case L)

Any thought very welcome !

Hi TIM036,
Both the 28 pin and 44 pin versions of the MX170F256 running MMbasic ver 4.6B, have the same RAM and clock speeds. The only difference is the number of I/O pis available. The 28 pin MX170, being a DIP package offers 19 I/O pins and is Breadboard or vero board friendly. The 44 pin version has 33 I/O pins in a TQFP SMD format.
At the command prompt Type PRINT MM.VER (enter) this will tell you the MM basic version.
Check out the manual for XMODEM send/recieve and EDIT comands for retrieving/loading/editing Umite programs

Have you downloaded the manual from Geoff's web site, most questions will be answered there. To find the current version of software use the command MM.VER. As far as I know the 44 pinner only offers more I/O pins. Downloading and uploading can easily be done using MM EDIT available from the web site.
Paul.

Edit. There is a beta of the PIC32MX470 available that has more memory and speed.Edited by palcal 2015-05-22

Saving a mmbasic programs to my Laptop. Also to be able to load them into MicroMite from the laptop.

I use Ubuntu 14.04 Linux, so Windows solutions are not what I need. (not keen to change OS).

Best I've found so far is:-

Quote:-

Xmodem

the best way to pass a file through xmodem is to use 'sx'. In debian this application is part of 'lrzsz' package.

In debian:

apt-get install screen lrzsz

screen /dev/ttyUSB0 115200

Then press Ctrl-A followed by : and type:

exec !! sx yourbinary.bin

This will send the file to ttyUSB0 over xmodem protocol

end quote

For 'Edit' in the mmbasic manual, all I found was on page 45 and 46 and that was it.

______

I guess I'm having a typical 'Newbie' panic attack, on this detail of being able to save and reload software into MMBasic.

Is there an Idiots guide how to do it ?

(I'm note sure if there is such a thing as a VT100 emulator in Linux available software archives)

Practically every serious user must stumble into the same problem ? I feel a bit of a dumbo that I've not yet spotted it !

Any thoughts very welcome !

A puzzled,

Tim
