Mini TFT 240x240

Post by stirucherai »

Got 2 Mini 1.3inch 240x240
One is working and second one is not working

Attached the picture which shows working and not working unit. Both were added to same RaspBerry PI Zero W unit (obvious after shutdown)

Thanks and Regards

Does anything show up in an I2C scan?

pi@BDLThirucherai:/var/www/html $ sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --

pi@BDLThirucherai:~ $ sudo python3 blinka.py
Hello blinka!
Digital IO ok!
I2C ok!
SPI ok!
done!
pi@BDLThirucherai:~ $

Please note for the working unit also the output is same. As mentioned earlier the base unit was same (with same OS install of micro SD card )

Thanks for the photo. There's a chance maybe the ribbon cable is not fully inserted? Worth trying at least. Do this unpowered. Push the little black retainer tabs (arrow) out to release, then push the ribbon cable in snuggly, and then push the retainer tabs back in.

You can use your other TFT for comparison. The product photo also appears much more inserted:
