Hello Barry
I've also got DMR running with the ThumbDV now on the software I'm doing (slowly but surely).
DMR uses rate 33 mode on the AMBE-3000 chip. Exactly the same audio quality as Fusion DN (half

Re: Raspberry Pi 3?
The problem is that on the Pi3 the GPU clock frequency can vary, unless it
is locked to 250 MHz, then reducing performance.
There is a load of stuff about this on the PI forums.

Re: Raspberry Pi 3?
I’m not sure where you’re getting this from. The Mini-UART is clocked off of the “core” clock. The GPU is default off of this PLL. The firmware sets this speed to 250MHz on the RPi 2, and,

Re: Raspberry Pi 3?
Jeremy,
I think youve missed my point. The Pi3 now has /dev/ttyS0 where
/dev/ttyAMS0 used to be without adding any overlays. But by default its
speed will vary with the GPU clock, and will start

Re: Raspberry Pi 3?
show how much I looked into this.. in that case things look much better, but I didn't actually use the chip dummy repeater loads now and no errors with the test script.

Re: Raspberry Pi 3?
The device name has changed. You'll need to change it in both of them:
python AMBEtest3.py -s /dev/ttyS0
or
AMBEserver -i /dev/ttyS0

Re: Raspberry Pi 3?
Jeremy if you want to play with a rpi3 hit me up offline and I can enable your RDP/SSH into mine to play around with. has a GPIO DV3000 on it right now.

my testing is not definitive I quickly tried to put it back on the GPIO
... one yes it needs more power 2.5a to boot and I gave it 3a with the DV3000 GPIO
python AMBEtest3.py

Re: Raspberry Pi 3?
There have been some significant changesto the serial port (ttyAMA0 is now used for Bluetooth, and the new ttyS0’sspeed depends on the GPU clock), so probably not without some work.

Re: Raspberry Pi 3?
We don't have one for testing yet, but there shouldn't be a reason why it wouldn't. I'd start with the PI 2 configuration.

Re: Raspberry Pi 3?
We’re interested. I have three on order.
There actually is a set of solder pads on the bottom side of the board to solder in a connector. That being said, it’s not really “manufacturable”
