I have a new beta version (B32) for the Micromite and Micromite Plus and it can be downloaded from the usual place: http://geoffg.net/Downloads/Micromite/Micromite_4.7_Beta.zip (clear your browser cache first).

The big feature in this version is that it supports the 100-pin chip

. The User Manual (included in the download) has been updated to list the pinouts for the 100-pin chip (page 12).

This module is useful if you are experimenting with the 100-pin Micromite Plus: http://www.microcontroller-board.com/snadpic-board-32/14-snadpic-pic32mx470f512l-development-board.html#/crystal_oscilla tor-20mhz/crystal_rtcc-no_without_crystal_r

This is the company's standard PIC32 experimental board modified to suit the Micromite Plus firmware (it has a 20MHz crystal and does not include a RTC crystal). If you are purchasing this board make sure that you specify these two details and the words "For Micromite" in the comments field.

On this module the SD Card Chip Select (CS) signal is on pin 14 and the Card Detect (CD) signal is on pin 18. So, to enable the SD Card on this module the command is: OPTION SDCARD 14, 18

Note that on the 100-pin Micromite Plus pin 18 is used for driving a SSD1963 based LCD panel and will conflict with its allocation as Card Detect. In this case the zero ohm resistor J3 on the underside of the SnadPIC board must be removed so that SD Card Detect is no longer on pin 18. Another pin may be selected via the CD pin on the top of the board.

Hi,

tried it with the modified snadpic rev 1.02 (it has a 20MHz crystal and does not include a RTC crystal).
I use an External Power Supply, Power Switch to EX.PWR.
USB shows a new com Port (3).
But with terraterm no Output.....

What do i wrong ?

What PINs on the snadpic are used for serial console?

@Geoff,

From MM Advanced Features (Page 14):

Quote To seek to a record within the file you would use the SEEK command which will position the read/write pointer to a specific byte. The first byte in a file is numbered one so, for example, the fifth record in a file that uses 64 byte records would start at byte 257. In that case you would use the following to point to it:
SEEK #1, 257

Should this not be 231? I am currently reading about SD file access (not in a position to try it just yet) and am either missing something, or, this is a 'typo'?

Please can someone confirm . . .

WW

EDIT

GOT It now! my mistake (can't add up at the moment!!

I just tested it on a SnapPIC and the USB console works fine. It must be something in your configuration of Tera Term.

Thanks and I do apologise. It is impossible to test all variations of commands like this and there always seems to be a bug hiding where I did not look. This only occurs on a MM+ when there is no LCD panel configured.

I will fix it in the next beta.

Hello,

what is the default baudrate for USB console?

Device manager shows a Microsoft Driver, is this as expected?

I use WIN 10!Edited by atmega8 2015-09-28

The MM+ ignores the baud rate so you can set it to whatever you want.

I have not tested the USB on Win 10, that is next.

I've had an enforced holiday in hospital, so just catching up. In the latest (b32) advanced manual there are no pin numbers listed for the Displays to connect to the 100 pin chip.

Best wishes to you, Paul.

I hope it was not a long stay in hospital, and hope you have a speedy recovery.

Paul.

In the micromite manual page 12, the 100 pin pins are labeled with the display pin descriptions so it should be relatively easy to work it out.

I will try and fill out the table sometime today....

Thanks Grogs, 4 days but they can make a mess in that time with a scalpel. It's been 2 weeks and I'm still very sore.
BTW I wasn't reporting an error in the Manual, I have a SnadPic board up and running and want to connect a display, I need the pinout.

Sorry, I missed that. I have updated the manual in the download (http://geoffg.net/Downloads/Micromite/Micromite_4.7_Beta.zip - clear your browser cache first).

Another update required to the Advanced Features manual. Find and replace this sentence

'#ref' is the control's reference (a number from 1 to 50).

with

'#ref' is the control's reference (a number from 1 to 100).

to reflect the increase in controls from 50 to 100 in beta 29.

I was going to ask if this could be increased as I need 51 controls!

Thanks.

On another subject addressed to everyone. I have to report that fixing the USB and Windows 10 issue will take much longer than I anticipated. There appears to be two issues - the first is that Win10 is not enumerating the USB correctly on the initial connection. I believe that I have fixed that but the second issue (the Win10 driver hanging after the initial connection) is much harder, mostly because is proving difficult to identify the culprit.

The current MM+ beta works fine with Windows 7, so that points the finger at Win10. But the Maximite (which runs essentially the same USB code) works fine on both Win7 and Win10, so that implies that there is a subtle difference between the MX795 and MX470 chips. If you ask Microchip about this they say use the code from Harmony (Aaaggghhh). To make it worse the problem seems to be a timing issue as sometimes it almost works and other times it does not.

So, for the moment the MM+ USB and Win10 are incompatible.

@Geoff,

Please could you consider adding a 'default' backlight parameter to the OPTION LCDPANEL SSD1963.... command (ideally in-between the 'default-font' and the 'optional backlight pin)?

This should work in the same way that the 'default-font' works, i.e. on a reset or power-up, the backlight is set to the default value. Any other time, it can be changed by the existing BACKLIGHT command.

Thanks for your consideration,

WW

MM Advanced Features manual (Page 13):

Quote CLOSE #nbr [,#nbr] ...
Close the file(s) previously opened with the file number �nbr�.

To keep consistency, each occurrence of '#nbr' should be replaced with #fnbr

ALSO, in the same section:

Currently there are three 'SD-file' commands incorporating #fnbr, and also having one other parameter (as follows):
LINE INPUT #fnbr, variable$
SEEK #fnbr, pos
INPUT$(nbr, #fnbr)

Can I suggest that #fnbr always comes first and hence the last command becomes INPUT$(#fnbr, nbr).

I'm not sure if the above follow any 'standard' forms of BASIC, but keeping things 'simple' can only be a benefit to a user (and it saves repeatedly looking at a manual to work out which sequence parameters need to come in for 'similar' commands)

Just a suggestion . . . .

Strange restarting issue (bug?)

My usual set-up (SSD1963, PS2, standalone system) with latest Beta

OPTION ERROR CONTINUE
OPEN "test.dat" FOR RANDOM AS #5
if MM.ERRNO = 1 then print "No SD Card"
if MM.ERRNO = 2 then print "Write Protected"
SEEK #5,1
A$=INPUT$(100,#5)
? A$

With SD card in then I see data within the 'test.dat' file.
With SD out, then correct message: 'No SD Card'
If I then switch WP on (on the SD card), then system resets
Subsequent running with WP on results in the expected message: 'Write Protected'

Seems like this may be a bug . . .

WW

Now I can't get this 'error'??? Working correctly 100% of the time without a single reset . .

Please can anyone else try this to see if you get any strange resets? Thanks
