Thanks for the examples. I've tried this and it really works! It feels somewhat slower (I'm using user-defined characters) but that probably doesn't warrant its own driver. So I'll contribute a documentation change that adds an example of how to use the I2C-enabled version of the display, this may be non-obvious to others. I'll start a new thread for this, stay tuned... @Miguel: Thanks for your detailed feedback on coding style, I'll use this next time ;-) Ralf -- Ralf Schlatterbeck Tel: +43/2243/26465-16 Open Source Consulting www: www.runtux.com Reichergasse 131, A-3411 Weidling email: off...@runtux.com
