All: I don't think Hamlib is going to be a viable solution as it is currently implemented. It makes resource assumptions that are simply beyond what can be expected from a Nano. Also, the Serial library that is standard with the Arduino IDE is written in such a way that it blocks while active. Both of these mean that you'd need to modify those libraries to shoehorn them into the Nano in a manner similar to what Allard pulled off. I have also written a "crippled" CAT, but for the X1M and a Nano. Still, to have a small xcvr tied to a PC kinda made it less useful to me, so I gave up on it. The CAT part was written in C# using visual studio, but could probably be ported over to C++ pretty easily. As always, I'd be happy to share that code with anyone who is interested. (It's pretty ugly as I haven't spent much time on it.)

I just can't put my finger on an example at the moment. cheers, Graham ve3gtc On 12/7/2017, "Ashhar Farhan" <farhanbox@...> wrote: >guys, > >i have implemented a very minimal version of CAT in the ubitx. it works >with fldigi, but it doesnt work with WSJTX. the reason. here is what is >happening: >The hamlib opens the serial port, which resets the Arduino Nano. >Hamlib immediately sends a command to the Arduino Nano >But the Arduino Nano waits a while for the programming commands before >executing the sketch code >So, the Hamlib times out! > >Is there a way out of this? > >- f > >On Thu, Dec 7, 2017 at 2:03 AM, Dimitar Pavlov via Groups.Io < >lz1dpn=[email protected]> wrote: > >> Hi, >> >> Check this links, I think will be interesting for You. >> This arduino source is Yaesu FT-817 transceiver emulator to computer USB >> port (COMx). >> Worked very slow with arduino, but with STM controller will be better. >> >> >> >> Peppermint-VFOsi5351 >> >> Peppermint-VFOsi570 >> <> >> >> >> >> >> 73! >> >> >> > > |
