It may be possible to do this, yes. I believe that the TQFP parts (in Netzpfuscher's PCB) are basically a superset of the QFNs on the dev board, so that any pin selection that works for the dev board can also work for a TQFP based PCB.

Unfortunately the PCBs out in the wild (those from when Steve Ward built his, Netzpfuscher's and one that I have) are designed around a pinout that can't be replicated with a dev board, so there'll always be a need for a couple of different configs. None of this is particularly hard, it's just annoying as someone has to muck about changing stuff for every code release.

I reorganized the code and found a relatively good solution for the different boards. I split the code in a common code base and the board specific files. The common code is linked in the board specific folders. The _QFN projects are for the dev board and the _TQFP for the classic boards.

If someone gives me the pinout of the dev board version I merge it to the git. I only need the ".cydwr" file. Or clone the new repository and make a pull request.

common:
binary Binary files like the precompiled bootloader
ntshell Shell code
rtos FreeRTOS code
uart_ldr UART-Bootloader code
ud3core UD3 code

Here is what I have for the cydwr attached.  I also changed the clocks around as well.

Thanks,

Dan

There are a bunch of new features incoming. https://github.com/Netzpfuscher/UD3/tree/burst_mode

  • Ethernet support with a Wiznet W5500
  • Teslaterm with IP-Support
  • Teslaterm now has a MIDI-In. With a virtual MIDI-Port it is possible to send MIDI from every App you like
  • Teslaterm with support for a Korg nanoKONTROL2 controller
  • The UART is equipped with a protocol and transport layer for error detection and retransmission (https://github.com/min-protocol/min)
  • Burst mode interrupter

The Ethernet connects to the 8pin header on the UD3. I think Ethernet is a good choice. It is isolated, cheap and you don't need special Hardware. If you want to run a multi coil system, you can throw a switch between the coils and connect a fiber Ethernet to the computer. If I have the Firmware in a good state, I upload a release in binary form. I think it is much easier to flash a binary for someone who is no programmer ^^

We hit the 2m ^^

I've made several bugfixes. Ethernet is working, Teslaterm is more stable.

Actually I'm working on the duty cycle limiter for the MIDI mode. My first proof of concept works relatively good. There are no more big current spikes if a very high MIDI-Note is playing.

I've added a new synthesizer in the UD3. The new synthesizer "emulates" the famous SID chip. The UD3 interprets the music on a register level. The noise synthesis of the SID makes a very nice drum effects.

Very neat  :)
There was a short discussion on 4hv a few years ago on tricks to enhance TC sounds.

Cool, new stuff to play with :)
Unfortunately I haven't had time to do much work on coiling recently, but I will be giving your new code a go when I get a chance. I'll also be in NZ again at the end of the year, so will have my large coil to play with too (I have a 75% finished UD3 board to install into it). On that note, Uspring - I'll be having another go at the toroid current measurements I promised and failed to do in April, this time I will have a lot more time to spare and hopefully won't injure my back trying to lift the coil down out of storage like I did in April!

Great progress on the UD3 Netzpfuscher!

I will set it up as a goal for this winter to get a working UD3 with your software :)

One warning. The newest GIT-Version of the Dev-Board UD3 software has a messy pinout. I need to correct this before I merge it in the master branch. I use the dev-board for ethernet debugging so it is a little bit hackish. In general there is heavy work in progress ^^

I also work on a new PCB revision in Kicad with integrated Ethernet. Ethernet works so great and doesn't need special Hardware. I think it is better to go away from the expensive Altium ^^


Thanks to malte0811 the Teslaterm is growing. He added a scripting feature to automate the coil for show use.
In general the UD3 ist still fully functional with a normal VT100 Terminal.
