some imperfections in the SRIO and MF handler have been fixed in this release. Additionally V1.1 provides following new functions:
MIOS_HLP_16bitAddSaturate : 16 bit addition with saturation. Usefull in conjunction with rotary encoders. Will be used by upcoming applications (MIDIbox HN already uses this function in hn_enc.inc)
support for detented encoders (see mios_tables.inc)
MIOS_DIN_PinAutoRepeatEnable , MIOS_DIN_PinAutoRepeatDisable , MIOS_DIN_PinAutoRepeatGet : an assignable autorepeat function for every button. Excellent for data entry. Used by Magic MIDI Delay and Motorfader Calibration App.
MIOS_CLCD_SpecialCharInit , MIOS_CLCD_SpecialCharsInit : allows to initialize the 8 special characters of a LCD.
MIOS_LCD_YAddressSet : allows to enable a second character LCD
The last function is now used by the MIDIbox LC application in order to drive two LCDs. This is a nice alternative solution compared to a graphical LCD - the characters are bigger and therefore the faders and V-pots can be arranged better on the panel (more space between the faders)
The inputs of the second LCD have to be connected 1:1 with the control lines of the first LCD. Just only the E (enable) input requires a seperate interconnection to the core module: J10:RC (pin RC.4 of the PIC)
It’s very hard to make photos from the LCDs due to unwanted mirroring effects. Here are the only tries which adumbrate how it looks like:
For comparison only the screen of a graphical LCD (sorry again for the bad quality…)
Hopefully I will find some time to documentate all the new stuff (instead of programming new functions ;-))
Best Regards, Thorsten.
P.S.: thanks to Axel/Frank/Rasmus (in alphabetical order) for beta-testing!
I think the configuration with two 2*40 LCDs is better but I think is cheapper to get one 128*64 Got to do some research.
I purchased the 2x40 LCDs for 5 Euro per piece at EBay.
The split mode for encoders: how many encoders support?
8 encoders or 16, if you replace the motorfaders by encoders. However, this mode is provided by the host application, it just swaps (alternates) the function of V-pots and motorfaders with one push of a button. So - 16 rotary encoders make only sense if you plan to use your box also with other MIOS applications. If you want to save money, use 8 encoders. If you find some nice faders (without motors), you can use them too.
Is there a particular way of cabling all the DINX4 together to achive the right orientation of mute solo etc?
See mios_tables.inc in the source archive. But you can also assign the functions to other DIN pins if you want.
sure the system architecture of MIOS is quite stable, everything has been pepared for more complex applications…
See: mios_tables.inc, where you can configure 64 rotary encoders
As I wrote in another article, a port of MIDIbox64seq to MIOS is planned, and the sequencer engine will be reusable for other types of sequencers. Rotary encoders and graphical LCD: no problem! But you have to enhance the application code by yourself or you have to hope that somebody else publishes his modifcations!
Got to do some research.
