Description New to the LCD2041 has added ﬁve non-volatile memory banks for

custom character storage. This is intended to allow you to create your

own custom bar graphs, medium/large numbers and startup screen.

However, each memory bank may be used to store a set of any eight

custom characters; with the only provision being that memory bank zero

contains the characters that will be used in the startup screen. By default

the memory banks will be loaded as follows:

[Bank] Description

0 Startup screen characters.

1 Horizontal bars

2 Vertical bars

3 Medium numbers

4 Large numbers

In order to save new custom characters into a memory bank, follow the

same process as you would for creating a custom character, see Sec-

tion 6.2 on page 26, only use 254 193 [Bank Number] before sending the

[ID] and character [Data].
