Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi all,

I have only just joined the forum, but I have been reading it for a while.

I purchased an E100 kit last October and have been struggling with my 5" SSD1963 since then.

Reducing the CPU speed to 80 MHz improved things somewhat but did not fully resolve the problem.

I also did the LCD backlight mod described by matherp, but it did not make any difference for my 5" display. However it did have the collateral benefit of improving the efficiency of the display lighting by 34%, and reduced the overall 5V load of the backpack by more than 20%. (My 5"display looks identical to the one shown in Silicon Chip in August 2016.)

I have only just caught up with the latest developments on this problem and have just upgraded my MM firmware from V5.04.04 to V5.04.09_Beta_9. That has solved all my 5" display problems completely.

I'm happy to acknowledge the support of Graeme from Rictec in getting to this point, and the rest of you for your helpful posts.

Welcome aboard.
Good news on that LCD thing.
That's what we want to hear - that the bug-fixes are indeed fixing the bugs.

Hi all,

I have a new issue using the SD card with the same, originally problematic, 5" SSD1963 display, and also on a 7" SSD1963 (which has never given me a problem).

When I use SAVE IMAGE Screen$, with Screen$ = "Screen.bmp"

or more directly, SAVE IMAGE "Screen.bmp"

I get the message "SAVE IMAGE not available on thi"

I get this on both displays. I was not always getting a truncated message.  The full message was "SAVE IMAGE not available on this display",  or something equivalent.

I can load images OK, as in LOAD "tiger.bmp" or load T$, with T$="tiger.bmp".

I can also SAVE programs OK,  but LOAD-ing only works with the form

LOAD "ProgramName"  but NOT

LOAD P$ with P$ = "ProgramName".

I know that this query is not a good fit with this thread, but I did not want to start a new thread for such a trivial problem.  I guess I am just doing something silly.

I will be grateful for any suggestions.

Best wishes,

Lew.

PS  I updated the firmware from 5.04.09 Beta 4 to 5.05.03 today.  That did not make any difference.
