Bodmer,
Thank you for your time and patience in posting and troubleshooting these displays. It looks like there are several iterations of this display using the same designations. Unfortunately, I'm still struggling to get mine to work. I am getting streaking, static, and ghosts.
All,
I bought several of the "KMR-1.8 SPI" "ST7735" displays from eBay. The parts bags have the following identifiers: SKU276159 EVK 122--300503--300503." The display itself has the following identifier on the top edge: MYT-1610-180-M2015-10-27" Please help me get this display running.
I am using an Uno clone.
Using the identification script (post #13) My display comes up as "unknown"
TFT driver register values:
===========================
Register 0x01: 0x00
Register 0x04: 0x9102
Register 0x09: 0x610000
Register 0x0A: 0x08
Register 0x0B: 0x00
Register 0x0C: 0x06
Register 0x0D: 0x00
Register 0x0E: 0x00
Register 0x0F: 0x00
Register 0x2E: 0xFFFFFF
Register 0xDA: 0x00
Register 0xDB: 0x91
Register 0xDC: 0x02
===========================
Looks like driver chip is: Unknown
Wiring:
Uno Display
8 (DC) A0
9 (RST) RESET
10 (CS) CS
11 (MOSI) SDA
13 (SCLK) SCL
GND GND
5V VCC
GND LED-
3.3V LED+ Note: this is temporary LED will be PWM on pin 3 eventually with a resistor inline (R value unknown)
Drivers attempted:
TFT_ST7735.h (INITB, GREENTAB, REDTAB, BLACKTAB, GREENTAB2)
TFT_S6D02A1.h
TFT_ILI9163.h
ADAFruit ST7735
TFT_ST7735.h BLACKTAB worked the "best" but none were right.
I also tried adding a 1K2 (1.25k 1%)Resistors on 8,9,10,11 and 13. Unfortunately, not will all drivers. Alas, no worky.
As a neophyte and have been researching to make as much progress as I can. But, I'm at an impasse. Driver code doesn't appear to work properly and I'm struggling with the resistors. Do I need them? on which leads? I have not yet tried a voltage divider. Do I need a voltage divider?
Attached are front of display, rear of display, flex circuit of display, and an example of the display errors.
Thanks in advance.
