LCD3310 on A13

[fractor]

Hi,

I am trying to get the MOD-LCD3310 going with my A13 WiFi board. I found the imx233 demo but obviously, the underlying  gpio-mmap.h is not compatible. Moreover: Shouldn't the UEXT port be used with i2c rather than GPIO?

Any help appreciated getting the LCD going...

Thank you!

Hi all,

I am glad to be able to say that I can respond to my own email question. So in case anybody is interested, I got the LCD3310 working on the A13,. It seemed, however, an unfeasible amount of work to do that using the standard connector and UEXT. This involves re-patching the kernel from I2C to SPI and also not being able to use the RTC module :-(

Instead, I connected the LCD to the GPIO2 port and rewrote the iMX233 demo code from the Olimex GIT repository (https://github.com/OLIMEX/OLINUXINO/tree/master/SOFTWARE/iMX233/MOD-LCD3310) to reflect the wiring.

As a bonus, I threw in a PBM decoder, so one can display graphic files (converted from monochrome PNG, BMP, PDF and others) on the LCD3310. Load your old Nokia logos!

Good luck with it!
