mariosgit / vfd_mn12864k

Arduino/PlatformIO lib for MN12864K

AdafruitGFX lib compatible driver for an MN12832JC VFD display.

Experimental !!!

Supposed to work with TeensyLC, could be possible on Arduinos too, just check the refreshDisplay interrupt call.

Todo

• GLAT is high in the connection drawing ???
• GBLK ???
• resistor at VDD2

Dependencies:

• mbLog, stdout style serial log, can be found in mariosgit/mbLog

Pinout, Connections

• These are hardcoded, see mbGFX_MN12864K.cpp
