LCD Library Enhancement request

January 07, 2010, 05:31:06 am

First, thanks for a great little product. I got a V3 from Seed Studio and it's already proving to be very useful.
I'd like to be able to use the LCD library with a different IO expander (which uses a different I2C address).
Is is possible to make the I2C address configurable at run-time?

(I've already added an issue to the google code about this, but then I thought that maybe I should have asked in here first?)

Thanks Matt,

I've added it to my list of to-dos for the next release. It probably won't happen until I get the new bootloader out because any extra code will start to reach into an unerasable memory location and that causes issues. After the new bootloader is installed we should have an extra 6K of space or so for enhancements though.

Thanks Ian.
In the short term, I'll try changing the hard-coded value and re-building the firmware

Please remind me if it isn't updated after the new bootloader is out, sometimes these things get lost in the shuffle and I really want to add this feature.
