DVPi schematic final version
I know some nice PCBs are designed for DVPi. I also ordered 5 samples of the PCB designed by EA7GIB and recently received it.
However, I had to add one LED and one switch to the needs of users. But this is just an option. Add this feature only if you need it.
You must read the document below link before reading this document.
This document is an extension of the document at the link above. Most of the DVPi's hardware is explained in the link above.
This document describes only recently added hardware.
2.1 Added TX Led (transmission)
An LED has been added to indicate TX (transmission).
This can also be replaced by the PC817, just like the RX Led.
It can be used usefully when using the PTT button on touch screen or Vox function .
2.2 Fun2 S/W
The final version of DVPi supports Dual VFO and D-Star.
Function 2 switch can be used in Dual VFO or mode change (DMR <-> D-Star) according to user's selection.
GPIO_FUNC2_TYPE=1 : Function 2 switch is used to change VFO (Vfo A <-> Vfo B)
GPIO_FUNC2_TYPE=0 : Function 2 switch is used to change Mode (DMR <-> D-Star)
Again, DVPi can be used without any hardware. Just, if you need, you can add any hardware you want as RX Led, rotary Encoder ...
Recently, the hose.brandmeister.network server went down. So, Talk group information is not displayed in DVPi.
I'll wait a few more days and look for other ways before DVPi 1.0.
We can bring the Lastheard information from https://brandmeister.network/ but it will require quite a bit of network traffic.
Let's find a better way together.
Could you make V. 0.8 available so we can test everything ..ReplyDelete
Thanks Maurizio I3YBD
I'm doing some tests to get the D-Star and Dual VFO builtin. I will release Version 0.8 in a few days.Delete
Thank you for your supoort.
Thank you for all the functions and circuits of DVPi.ReplyDelete
In Korea, we are working on a joint production of DVPi.
Design and PCB Artwork will be finalized soon.
Many OMs, including me, thank you.
I think DVPi will contribute a lot to the development and expansion of DV communication.
Thanks for your interest.Delete
Just test Version 0.8 and distribute the stable Version 0.9.
There are no functional additions from Version 0.8. I will only stabilize it until Version 1.0 is reached.
For the hardware, this is the final version.
I applaud your passion and dedication. Everything is ready. We look forward to the launch of the program. Thank you.ReplyDelete
Thanks for your interest and support.Delete
I just released Version 0.88
i applaud alsoDelete
Hi Ian, appreciate your efforts on DVpi, and I love it. Another fun of DVpi is to watch YouTube with cute 3.5" LCD screen, response time is slow, but still fun. In the future, will you consider to set screen resolution to 640 x 480? instead of 720 x 480? if so, I do not need to change resolution when I watch Youtube. Thank youReplyDelete
That's a great idea. In fact, I don't do DMR communication very often, so I was looking for another use of DVPi.
Good morning LanReplyDelete
I noticed this anomaly .. maybe not, if the DVPi is being listened to on a Talk Group and we want to change it to another TG it is not possible to switch to another one and it does not change even confirm it with the group selection button ... is this normal?
Thank you, 73 I3YBD Maurizio
Yes it is normal.Delete
That's because it doesn't change immediately on the DMR network. I tried processing with a different timeslot, but there was no big difference.
You can manage your sessions on the brandmeister homepage.
is 2.2 Fun2 S/W located in file dvpi.ini?
I released Version 0.8 today. This is a feature in Version 0.8 IanDelete
it took me a while to figure out that the way to use the rotary encoder was to rotate to the desired TG # shown at bottom and then wait until the panel displaying the selected TG blinked and disappeared .... and then depress the encoder button down. All functions working great ... waiting for Version .8/.9 to try DStar.
I have just purchased 5 of the Version 4 boards do you have access to the documentations for this version I can only find the version 3 information. de VK6NJP
I am waiting for the new version of the Front Panel that will have the button to select the Dstar or DMR that the Korean colleagues are preparing it.Delete
hi, will it be possible to implement bluetooth functionality to use wireless microphones?ReplyDelete
If I buy a Bluetooth Microphone, I will test it by enabling Bluetooth.
We have everything ready to go to Version 0.9 how are the tests you are doing going ... ??? do you think you can find the time to put it at your disposal ???
I just released Version 0.88Delete
From Version 0.9 to Version 1.0, we will continue to stabilize.
Fun DVPi is created with your efforts.
