ST7735 inverted colors

I’m following on from issue #79 which has now been merged.

I bought a similar LCD display from pimoroni Works great, however, if I run python3 examples/colors.py -f conf/st7735.conf the colours are inverted. For ‘red’ I get yellow, ‘green’ turns magenta, etc. Same goes for any example, not just color.py.

And I have no idea what the --bgr flag does but it didn’t make a difference for me.

For this display I changed the conf file to

--display=st7735
--interface=spi
--spi-bus-speed=16000000
--gpio-data-command=9
--gpio-backlight=19
--width=160
--height=80
--backlight-active=high
--spi-cs-high=true
--spi-device=1
--v-offset=26
--h-offset=1

Does anybody have a suggestion? Thanks

@jackjameshoward try sudo -H pip3 install -U Pillow

Yes, updating Pillow worked. And the --inverse flag works now too.

I could also revise luma.core.bitmap_font to support versions using the older code.

What do you say @rm-hull?

sorry for non-reply, … i get so many notifications from github that they often get classified as spam and end up in the junk folder.

@jackjameshoward I’ll add your conf file to the examples repo
