Firmware 20170503 and st7735

[angr77]

Hi!

I just for fun updatated my MD (Arm 120 MHz) and a 1,8 color screen (st7735) to fw 20170503.

The update went through great but I have problems with the LCD back light. After 3 seconds it disappears because it goes to the defined LCD dimmmer settings. In that stage I am trying to change the setting...and raise the dimmer settings using MDM but nothing seems to happen.

How does this work?

Best regards from a old MD friend

I'll check it today.

I just tested it and it works fine. The LCD becomes visible with LCD contrast above ~70.

Hi!

Yes, you were right Dmitri, a contrast value above 70 made the trick. (I was maybe locked on the old display...where a value above 50 would do the trick

I just played around with the settings...it looks like the MDM/MD implementation is generating a lot of timeouts when trying pressing the "Get All" or "Send All" on the global part of the MDM. (It is red more or less all time) I am using a USB 3 port on my computer with W10 Anniversary Update.

But it works better if you just do Get All/Send All for each individual areas - like misc, hi-hat or PADs. Then you are able to read/write settings to the MD.

The latest of course!

Looks like it is Windows specific. Please try this version: http://www.megadrum.info/downloads/Inst ... 170507.exe

Hi!

No - it still does not work with the 20170507 version of MDM for PC.

Also, please set SysEx delay to 100ms. It will not slow down MDM<->MegaDrum communication as in older MDM versions. This is now actually a maximum timeout between sending a Sysex and getting a response from MegaDrum so MDM will do next Sysex as soon as previous Sysex was confirmed.
