Hi Dave , With a 1khz 5v square wave output to dc/trig or ac input to measure on the Frementec Frequency display changes depending on which gate setting I use ,on 1S reads good ,10S reads 10khz ,on 100S mode reads as 100khz. Also at power up gate reads 'Mode' not 1S 10S or 100S. I just did the same test on Fy6800 and it properly displays 1khz on all gate settings . My earlier issue with the Trig input was down to the patch cable . While making adjustments to the measure panel on the pc I did get a couple of crashes where the program just closes after an error message . |

Were you seeing the wrong values on the front panel or the PC? I haven't flashed my FP yet, but the PC software shows 1.000kHz, 1.0000kHz and 1.00000kHz, which is as you'd expect. I've only managed to find one glitch so far, and that's on the Calibration Panel, when it does the same error behaviour. It's looking pretty resilient and stable otherwise. |

Theres a few small changes required for the FP software to be working right , I believe the bluepill software is a little ahead in that respect . Fp adds the extra 0 like you see Dave ,but looks like it forgets the decimal point ,so the number looks wrong . I have an idea which might be a nice feature to add, The abillity to arrange and automate a sequence of tones or arb waveforms , that would be incredibly usefull for test purposes . Rs232 is available ,would another usb to serial link connected to backpanel tx rx and gnd be the best way to go that way its entirely seperate from the internal usb used for the pc software . https://www.partsnotincluded.com/midi/how-to-send-receive-messages-over-serial/ that might do it |

Thank you very much for these efforts! Still didn't get anything from Feeltech - i owe you a beer at least ;) --- End quote --- Thank a lot for the feedback! It is still in development but what about beeing involved in testing the firmware? ;) --- End quote --- sure, hopefully this weekend i'll get to this, and try to dig a bit into testing... |

I loaded up the fy6600 serial protocall in open office calc ,seems to display nice ,but I havent a clue how it works , I saw the link to the guy who made WSPR the transmitter from the fy6600 , It seems like a way to automate the output of the generator would be really usefull for radio http://www.arrl.org/files/file/QEX_Next_Issue/May-June2019/Steber.pdf In this case a way to transcribe a text message into a waveform which is then uploaded to an empty slot in the Feeltech and schedualed for transmission at the next time interval, all automatically , I did have some limited success with the with the serial to midi I mentioned in my last post , I was able recieve a signal after power on from the Feeltech via midi in my daw , but I dont know how to send a meaningfull control signal the other direction . The idea of being able to use the feeltech in conjunction with midi and a sequencer seems to appeal to others as well . For audio testing the excellent 'Room Eq Wizard' by John Mulcahy has a midi and serial connections tab , if it had the abillity to control a generators output via serial that would be nice . I get the impression everything in the above wish lists is easily possible , all the hardware is there , the control protocall is there in black and white , its more like just hooking up the numbers in software . https://www.eevblog.com/forum/testgear/feeltech-fy3224s-24mhz-2-channel-dds-aw-function-signal-generator/550/ He seems to have made his pwn dedicated remote |
