The Commercial edition allows to use an external SPI Flash to store fonts. The EXT3-1 extension board includes an external 8 Mbits = 1 MBytes x 8 SPI Flash memory, labelled U1
.
The corresponding chip select pin is numbered 8
on the EXT3-1 extension board.
Configure¶
The fonts need to be uploaded to external SPI Flash.
Optionally, new fonts van be generated.
Use¶
