Our new high performance controller NL025 and new ZIF EVK boards have been released. (data sheet below)
An updated high speed NL024B controller is in the works and will be release later during July. (data sheet below)

Information regarding fonts and character sets in the NL022 controller:

By default we currently set in firmware the code page CP_1250 which sets the controller into a custom Hungarian font. Which is not to everyone’s liking. The general font for all other languages is the code page CP_437.

We will change the defaults in the next firmware release but for now, customers can just send the following commands to switch:

Default licensed font for latin chars please set the font code page to CP_437 after startup.
and set the charset to LATIN.

code page command:
#define CP_437    0
#define CP_1250   1

HEX:
0x74 0x00 will set it to CP_437

API:

1B 74 00 => Set to CP437
1B 74 01 => Set to CP1250

character set command for Latin:
Hex:
0x52 0x0B

API:

1b 52 0B
