I know that I said that it would be a while before the next beta but a couple of serious bugs surfaced so I thought it best to fix them immediately.

So an updated version (B37) can be downloaded from the usual place: http://geoffg.net/Downloads/Micromite/Micromite_4.7_Beta.zip (clear your browser cache first).

This fixes the "corrupt library" bug and a few more (see the file Changes.txt for the details). Again, my bug list is empty except for the Win10 USB issue.

This version also allows you to use any I/O pin for interrupts including the IRQ pin used by the touch controller.

As before, please let me know if you find an issue.

Thanks,
Geoff

Thanks for all your hard work and time spent fine Sir..!!

Will try out the new commands this weekend... (sweet)... Will be loading up the 170 28 pinners too...

THANKS Geoff.

By the way, in you change log, the last B37 entry reads as:
- With a non SSD1963 LCD using the BACKLIGHT command will now
cause an error.

Hopefully 'now' should be read as 'not' !

I will check this out later today (currently 07:30am).

Thanks again for all your commitment to the MicroMite; it really does keep getting better and better

Thanks for the update. One small change request. Would it be possible to specify whether the card detect pin on the SD card was active high or active low in OPTION SDCARD?

A possible syntax could be OPTION SDCARD CSpin, CDpin, WRpin, H/L, H/L

Many card slots seem to ground the CD pin when the card is removed and leave it floating when it is inserted.

Thanks

That's good thinking! I had to find a micro sd card holder with independent switch connections, which wasn't straight forward.

Here is a minor bug. MMBASIC doesn't catch the extra parenthesis.

Dim chars(900)), ASCIIptr(150,2), MsgData(maxbytes)

It does. It just saves it in flash for the next time that you forget the parenthesis.

That's where those unexplained errors come from... Two partial errors make a whole error and may only be revealed at the most inopportune time! It's Murphy's Law, you better know it, because you are going to live it.

Can someone please check the FILES [fspec$] command for me!

When I use FILES by itself, it mainly works ok (see later).
But with any 'fspec$' specified I get the message:
0 directories, 0 files

I mentioned above that 'FILES' mainly works ok. Sometimes it just 'hangs' with no response.

I have tried different SD cards, and different pins for CS, CD, and WP.

Thanks . . . .

@Geoffg

Just had the following error message whilst a program was running on B37:
CPU exception #7 (bus error on load or store) at address 0x9D04BF3C
Processor restarted

I had OPTION AUTORUN ON set, and I was browsing the web, so hence didn't see when it happened. But I have a ILI9341 setup on a 64pinner with SPI hardware running in a continuous loop.

Does the above error give you any clue as to what may have triggered it?

Thanks,
WW

Geoff, since the first release of MM+ this has been like a thorn in my b*** and I've always wanted to ask, why is the external crystal needed? The internal FRC in MX470 has 0.9% accuracy by specs and will be good for the USB. Isn't it possible to get rid of the external crystal, probably by an OPTION in order to keep compatibility with what's been done so far?

Another question (sorry, asking a lot recently, but that's because it is getting serious for many practical applications): would there be any possibility ever that a program may self-configure the device with all the needed OPTIONs and GUI CALIBRATE? Probably some function (maybe ISCONF(option id) is a possible choice) which will simply take a numeric parameter indicating the relevant option, and return 0 if that has not been configured, or 1 if it has. Thus the program will be able to find out whether certain options need to be executed only once. Of course they will need be to program executable as well as they are not at the moment.

@Geoffg

OPTION LIST is very useful. One thing that would be appreciated to be added to the list (albeit not an option!) is CPU speed.

I seem to remember matherp has posted CFunction details to do this but I think it would be a useful addition to incorporate the info into the OPTION LIST output.

Any thoughts . . . .

Page 17, Advanced Features manual.

The description for Font 4 reads "A bold version of font #4".

It should read "A bold version of font #3".

Thanks for the comments,

No, the change log is correct. Ie, BACKLIGHT only works with the SSD1963.

matherp said Would it be possible to specify whether the card detect pin on the SD card was active high or active low in OPTION SDCARD?

I will put it in the next beta. Obviously my exposure to SD card sockets is limited because I have not heard of this requirement before.

kiiid said I've always wanted to ask, why is the external crystal needed? The internal FRC in MX470 has 0.9% accuracy by specs and will be good for the USB. Isn't it possible to get rid of the external crystal, probably by an OPTION in order to keep compatibility with what's been done so far?

The problem is that the internal oscillator is NOT accurate enough for USB. Most of the time it will work but in a significant number of cases it will screw up the USB. I tried once to implement an automatic switch to the internal oscillator but that did not work (from memory there is a bug in the PIC32's auto failover). Finally, when designing the MM+ I figured that the MX470 was a complex enough device already (surface mount with many pins) that a crystal was not much of an added complication.

kiiid said would there be any possibility ever that a program may self-configure the device with all the needed OPTIONs and GUI CALIBRATE? Probably some function (maybe ISCONF(option id) is a possible choice) which will simply take a numeric parameter indicating the relevant option, and return 0 if that has not been configured, or 1 if it has.

Some people like the current system of saving the display options in flash, some don't. There are some good reasons for the way it is and the pros and cons have been debated quite a few times on this forum. For the moment I am sticking with the current system until I come across something MUCH better.

Greg Fordyce said Page 17, Advanced Features manual. The description for Font 4 reads "A bold version of font #4".

Thanks Greg and thanks to everyone for the feedback.

I am having problems configuring my MM+ touch control with beta37

> Micromite Plus MMBasic Ver 4.7 Beta 37
Copyright 2011-2015 Geoff Graham

> OPTION LCDPANEL SSD1963_7, RL, 4
> OPTION TOUCH 18, 21
Error: Pi

CPU exc

CPU exc

2 problems.
1. It is not happy.
2. I am unable to do anything other than re flash the chip to recover.

The same setup is OK on beta32. (I haven't tried it on beta36 yet)
OPTION TOUCH 18, 21, 50 which I normally use and is from the manual, gives the same error.

I don't know of any bug in that area and I have tested it extensively. It might be due to the subtle change in the OPTION LCDPANEL command introduced in B36.

You are using:

OPTION LCDPANEL SSD1963_7, RL, 4

Is the number 4 at the end intended to be the font or the backlight control I/O pin?

The new syntax is:

OPTION LCDPANEL controller, orientation [,LCD-A pin]

The default font has been moved to the OPTION LCDPANEL CONSOLE command.

The 4 is for the backlight control.
The LCD works as expected, it's just when I try to configure the TOUCH that I have problems.

My problem was pin 4.
It is used for SPI2 Clock.
By trying the setup commands in a different order, I was able to get a full error message without the continual rebooting.

> OPTION TOUCH 22, 50
> OPTION LCDPANEL SSD1963_7, RL, 4
Error: Pin 4 is reserved on startup
>

Now to find out why I used pin 4 in the first case...

Jim

Edit:
You are right, the 4 would have been the font size.
It would help if the OPTION TOUCH error message had time to display fully before rebooting.
