I've got an issue with http://www.ebay.co.uk/itm/1-44-inch-Full-Color-128x128-SPI-TFT-LCD-Display-Module-replace-OLED-for-Arduino/252442556424?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649
I purchased it 6 months or so ago. and got it working a demo sketch on a Nano, icsp pins. But then my laptop died losing all my data and sketches, which was a bummer as I'd just bought a mega to play with.
I've just got a desk top, so am returning to playing with Arduino, but try as I might I can not get it running on the Mega (not tried my Nano again yet) the pin markings are misleading as the use of scl and sda makes it look like it's I2C not spi!?!? it's only 8 pins as there is no SD card on it, marked as follows.
1 GND (I know where this goes lol)
2 VCC (this too, 3.3v)
3 SCL (SPI clock) pin 52 on Mega2560?
4 SDA (SPI data in) pin 50?
5 RES (Reset)
6 DC (data command select) is this SPI SS? pin 53?
7 CS (chip select) which is either hardware set or I change the sketch to the pin I want to use.
8 BL (back light control)
So my question is am I getting the above correct, and therefore it's a library issue?
Many thanks for any help,
