Vacuum Fluorescent Displays / M0216SD-162SDAR2-1 Jumper Settings
« on: March 25, 2016, 06:14:11 PM »
I am attempting to configure a M0216SD-162SDAR2-1 for serial interface, but cannot get the module to display anything.  I have the jumpers as follows:

J2 open
J3 short (solder bridge)
J5 short

J4 = 10k (default)
J6 = 0 (default)
J7 = open (default)

I have the connector signals as follows:
Pin 1: Gnd
Pin 2: +5V
Pin 3: Sdata
Pin 4: Strobe
Pin 5: N/C
Pin 6: Sclk

I am sending the following 16-bit groups after startup:

0xF838 (Function Set)
0xF806 (Display Entry Mode)
0xF80C (Display Enable)
0xF801 (Clear Display)
0xFA20, 0xFA30, 0xFA31, etc (Character data)

Display remains blank.  Any suggestions on what to check?  Many thanks.
