Tutorial - Graphic LCD Quickstart Guide
about 2 years ago
Has anyone tried this using the logic level converters? It looks from the picture that the D/C, SCLK, MOSI, and RES pins are all are connected through the TX pins on the logic level converters. Since all these pins send data from the microcontroller to the screen, shouldn’t they be connected to the RX lines?
If they do need to be connected to the RX lines, then one could simply produce the same exact circuit by connecting another 10K resistor from each signal pin to ground. This would create a voltage divider exactly like the logic level converters do. (of course, the vcc pin should be connected to 3.3 V for power!). I have tried this (voltage dividers and connecting to 3.3 V) and it seems to be working pretty well. I’m new here, is there a place I can upload the circuit I am using to benefit others?
