The MBSEQv4 beginner's guide is now up on the wiki with some images. I've used EsotericLabs' eps files (based on Wilba's design) for frontpanel overview images, I hope it's ok. In principle the guide is exportable as pdf and printable (there's a button on the right), though at the moment certain "table like things" don't get rendered correctly. I might replace the "tables" with images to take care of the problem. If you want to add sections and correct stuff, go ahead, that's the wiki way :-) The path to the guide from the wiki front page: MIDIbox Projects -> MIDIbox SEQ V4 -> MBSEQv4 Beginner's Guide http://wiki.midibox.org/doku.php?id=mididocs:seq:beginners_guide:start

Yes thanks for you old post. Very usefull :) I'm not sure the MIOS clcd driver initializes perfectly the 4 bits mod. http://svnmios.midibox.org/filedetails.php?repname=svn.mios&path=%2Ftrunk%2Fmios%2Fmios_clcd.inc Look at page 46 of the HD44780 spec : https://www.sparkfun.com/datasheets/LCD/HD44780.pdf The app_lcd.inc i attached follows it more strictly. Also i think the clear() commands should have a wait of 2ms. It's not very clear in the spec as the 1.52ms is mentioned for the "return home" function, but that was a bloker for my OLED to work, and it's what LiquidCrystal (HD44700 famous library) does. Best, Xavier
