Parameters
New to the VK202-25 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:
In order to save new custom characters into a memory bank, fol-
low the same process as you would for creating a custom character, see
Section 6.2 on page 25, only use 254 193 [Bank Number] before sending
the [ID] and character [Data].
Yes
This command is used to load the custom characters into the volatile
memory so that they may be used. If custom bar graph or number
characters are stored in the memory banks, this command may be used
instead of initializing the bar graph / number. To use this command send
the command bytes followed by the [Bank] that contains the custom
character data that you want to retrieve.
