additional info needed when using sainsmart st7735 tft about st7735_spi_stm32 HOT 5 OPEN

Just currently messing around trying to get this to work with libopencm3. Got it somewhat working with some cheap 128x128 screen. Still having issues with clears not filling the entire screen, and red showing up as blue and vice versa.

SCL == SCK (PB13 if your using SPI2)
I think RS/DC maps to A0 in this code (

Lemme know how you get on.

Ignore my comment about the blue <-> red thing -- http://cal-eng.com/?page_id=981. Just need to swap channels.

Also just fixed my issue with not filling the entire screen - just needed to add some calibration tweaks to the ST7735_AddrSet function (prob is a better way somewhere).

Hi illis. Thanks for the response. I got some time to work with it few weeks ago. Yes RS/DC goes to A0 and SCL is SCK. Using this code i was running into some wierd issues. I can print stuff on the screen now but only with 5x7 functions at 2x magnification. I see some unrecognizable scribbles with 5x7 1x, 7x11 1x and 2x . I havent tried any pictures yet on this display. I will try to get some snapshots of screen displays for various conditions and upload them here.

@RD2RTG One thing that springs to mind, could be the initization settings for the display - as there are a few variants (black/red/green/... tabs). I think I compared my init strings with some from here: https://github.com/adafruit/Adafruit-ST7735-Library/blob/master/Adafruit_ST7735.cpp#L138
