How to write the LCD5110 script of Python's TPYBoard driver
This article mainly introduces the relevant knowledge of "how to write Python's TPYBoard-driven LCD5110 script". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "how to write Python's TPYBoard driver LCD5110 script" can help you solve the problem.
TPYBoard driver LCD5110 of MicroPython
Let's take a look at the meaning of LCD5110 stitches (note: LCD5110 stitches are a little different)
The pins of TPYBoard correspond to the pins of 5110 as follows:
TPYBoard LCD5110 memo
-
# any Pin = > RST Reset pin (0=reset, 1=normal)
# any Pin = > CE Chip Enable (0=listen for input, 1=ignore input)
# any Pin = > DC Data/Command (0=commands, 1=data)
# MOSI = > DIN data flow (Master out, Slave in)
# SCK = > CLK SPI clock
# 3V3 or any Pin = > VCC 3.3V logic voltage (0=off, 1=on)
# any Pin = > LIGHT Light (0=on, 1=off)
# GND = > GND
If you still don't understand, just put the pin number on it.

-
Y10 = > RST Reset pin (0=reset, 1=normal)
Y11 = > CE Chip Enable (0=listen for input, 1=ignore input)
Y9 = > DC Data/Command (0=commands, 1=data)
X8 = > DIN data flow (Master out, Slave in)
X6 = > CLK SPI clock
VCC
Y12 = > LIGHT Light (0=on, 1=off)
GND
After connecting the ok, you can run main.py.
