Bosch GLM150 Range-finder Display..

[gamerpaddy]

I am looking for a Bosch GLM 150 Ranger Finder Display since the one in mine broke, its not officially available from Bosch, tho you can easily replace it (no glue, just clipped in, not soldered at all.)
i tried to find out how it works after not finding a replacement part for hours.

its a 128x128 i2c monochrome LCD that responds ACK to the addresses 0x70 and has its pixel data (128 transmissions with 32bytes each, 4 bits per pixel) on 0x72
it doesnt send any data back it just ACK's. 0x70 0x00 0x60 0x70 initiates a new frame, which is followed by 128 times 0x72 with 32 bytes of data.

size is about 48x43mm active pixel area or 50x52mm outter dimensions
it has a led backlight and a 6 pin ribbon cable, chip on glass, pinout is (in no particular order) Vbat, gnd, SCL, SDA, 3.3V and backlight pwm.

i wrote a program that lets me display its contents from a logic-analyzer capture to see how it talks to it. very simple protocol.

i also tried to use a esp32 microcontroller as a i2c slave to react on both 0x70 and 0x72 addresses (because without ACK, the range finder just hangs and retries) but its not quite up to the task.
it wont handle 2 slave addresses and the i2c sniffer just crashes the Serial port at 400khz bus speed when i let the broken displayed hooked up.
it might work when i dont use the serial port and directly process the data,  but its hard to debug without a debug console.


Does anyone know a display that fits these specs? pinout is my problem in the end.   
or any other solution to this?
