Liquid Crystal Library for STM32

Liquid Crystal Library for ARM STM32

This library allows a STM32 ARM microcontroller to control LiquidCrystal displays (LCDs) based on the Hitachi HD44780 (or a compatible) chipset, which is found on most text-based LCDs. This is a port of LiquidCrystal library from Arduino.

This library currently supports the following functionalities

• En/Dis Autoscroll

• En/Dis Blink

• En/Dis Cursor

• Custome Character

• On/Off Display

• Scrol Left or Right

• Serial Display

• Set Cursor position

• Changing Text Direction

Tip	The examples have been built for the STM32F3 Discovery, but the library should work on any STM32 ARM microcontroller.

Note	This library and its examples are originated from http://www.arduino.cc/en/Reference/LiquidCrystal

stm32liquidcrystal's Issues

Cursor position

Hi
When trying to print on the last column (on a 4x20 display), it does it on a different line. for example printing abc....xyz (I know they are 26 characters) from column 3, has the following output

_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 
y _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 
_ _ _ a b c d e f g h i j k l m n o q
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 

(BTW, I was testing scrolling the display but no scrolling is applied to the above output)
