- Wed Sep 23, 2015 4:09 pm #29724 the constructor should find line 1170:
static int16_t ucg_com_arduino_4wire_HW_SPI(ucg_t *ucg, int16_t msg, uint16_t arg, uint8_t *data)

but it did not !

you need Linux to run sh create_release.sh
if you are running Windows download Cygwin
The default download does not include the ZIP program which is needed so before you download open the Archive Package and select the ZIP program to be included in the download.

The create_release.sh will create a ZIP which you install into your library folder

To speed up the rendering add:
SPI.setFrequency(40000000);
to your sketch is the setup() section

Thanks spapadim

After many hours of trial and error I managed to get this thing working.

Fantastic!
Sorry for not being able to provide more guidance (I've always been a Unix person and even on laptops, where Unix is a bit of a PITA, I always had Cygwin to "survive" -- and when Windows 8 happened, I just switched to a MacBook ).

As for larger screens (> 2.8") with SPI, not really -- at least not with ucglib. There are some out there, but without a breakout PCB (just bare FPC). Breakout boards with larger displays that I've found so far either have unsupported TFT driver chips, or are hardwired for parallel i/f (which the ESP doesn't have enough pins for). If anyone finds one, I'm also interested (and also interested in IPS modules). Otherwise, someday I'll hack together a breakout and ship it out to DirtyPCBs or sth...
