pyupm_lcm1602 module

class pyupm_lcm1602.Lcm1602(*args)

Bases: object

API for the LCM1602 I2C controller for HD44780-based displays.

ID: lcm1602

Name: LCD Display Driver for the LCM1602 Controller for HD44780-based Displays

Category: display

Manufacturer: adafruit sparkfun seeed

Link:https://www.adafruit.com/datasheets/TC1602A-01T.pdf

Connection: i2c gpio This supports all sizes of HD44780 displays, from 16x2 to 4x20. The controller has no idea of the actual display hardware, so it lets you write farther than you can see. These displays with such controllers are available from various manufacturers with different I2C addresses. Adafruit* TC1602A-01T seems to be a well-documented example. The driver also supports parallel GPIO connections directly to the HD44780 in case you are not using an I2C expander/backpack.

Example for LCM1602 displays that use the I2C busCode sample for GPIO based LCM1602 displays
