Raspberry Pi SPI to Samsung VFD
Did a crude translation of the adafruit SPI_VFD arduino library to python on the raspberry Pi, with the target being the Samsung 20T202DA2JA vacuum fluorescent display.
I'll do a longer write-up when I have time. You need to install spidev as a prerequisite.
The key to getting output is sending a series of integers in a call as below:
def text(string):
L = [VFD_DATA]
for char in string:
L.append(ord(char))
spi.writebytes( list(L) )
text("Hello, World!")
