Edit: Should it be usefull, Modulation functions and Sweep functions can work together ... --- End quote --- Hi there! Sorry for the long break but the last year has been quite hard … That's just life… Here is revision 0.8 of the bluepill software with the corresponding modified PC Software. This works with a FY6600 with version 3.2 but this should also work with version <3.2, not with v3.3 All the existing functions of a FY6600 v3.2 are now integrated in this revision plus: - Sweep on CH2 - Over voltage protection - Variable load adjustment - Manual output range selection - Last config on startup available - Factory reset function - Amplitude, Offset + VCO-IN Calibration - CH1 modulation, CH1 & CH2 sweep and measure are independant functions and can be activated simultaneously. Thank you for your feedback! If someone is also interrested in testing , the same version is also available for the front panel with keyboard and lcd function but all the views are not finished (Channels, sweep, modulation and measure views are finished, system and configuration are still to be done). All the functions are anyway available through the PC Software. Although you don't need it, the bluepill version also works with a LCD, a keypad and an encoder but it is not 100% wired like the FY6600 so the binaries are not the same. If you have the hardware, you could also try the Bluepill with it (I would have to give you the modified wiring). I have a FY6800 and a FY6900 waiting to be connected to the logic analyzer ;-) The idea is to have at the end the front panel software working with the FY6600, FY6800 and FY6900, idealy with the same FPGA version if possible... |

This looks very impresive , you changed that shitty screen layout with many leading zeroes , better fonts and so on . I have v3.1 , the firmware will work ? |

It doesn't work with a V3.3 eeprom but as I don't have a V3.3 front panel, I can't see what changed in the FP-FPGA protocol for v3.3. |

Is this a cure for corrupted V 3.0 front panels? It looks *very* nice. F***Tech sent me a V 3.1 front panel. They are *supposedly* sending replacement '103 chips to other forum members with corrupted units though I've not gotten confirmation yet they have arrived.. I've got an ST-Link V 2.0 and am about to jump into working on the nanoVNA FW. If it is possible to load your front panel FW into a V 3.0 panel, I'll install jumper pins and try it out. Adding the SWD pins would be much less work than swapping out the chip. It would be really nice to see FOSS code that would allow other Chinese OEMs to clone the F***Techs and improve them. It could not happen to a more deserving company. Have Fun! Reg BTW if you use one of these as an RF source, checkout the nanoVNA. But be warned, the groups.io list is like trying to drink from a firehose. |

I'll need to get my brain into FY6600 mode again and dig out the STM programmer, but I'll certainly do what I can to help with the testing. The new FP display looks to be a massive improvement in legibility! Regards, Dave |
