I've connected a HD4478 LCD module to my Raspberry Pi 2 which is running Pi-Star.
The wiring is done like described in https://github.com/g4klx/MMDVMHost/blob ... ME.HD44780.
I'm not using I2c.
But it isn't working. posting.php?mode=post&f=3#
The Display shows nothing.
I've read that HD44780 support has to be compiled in to the mmdvmhost program.
Is the mmdvmhost version, contained in Pi-Star, compiled with HD44780 support?
If so, what do i have to configure to get the display working?
The usual things are already done: Set the "MMDVM Display Type" to "HD44780", in Expert Mode the MMDVMHost settings for "HD44780" are at their defaults. My Display is a 16*2 type.
Some lines from my /etc/mmdvmhost:
Code: Select all
[General] Display=HD44780 ... [HD44780] Rows=2 Columns=16 Pins=11,10,0,1,2,3 #I2CAddress=0x20 PWM=0 PWMPin=21 PWMBright=100 PWMDim=16 DisplayClock=1 UTC=0
