FY6900 Signal Generator USB PC interface

<< < (3/3)

mikejm:

The Arduino IDE works for me. I use the serial monitor under tools set at 115200. board is wifInfo and the port must be set. Use the Host Computer Protocol Specification. Most commands work the way all the other FY6900's work but Frequency commands are different on the FY6900-100M. In the other AWG's the decimal point is not used sending commands. Note the FY6900 display- The decimal point is assumed to be between 1KHz and 100Hz (000'000.000'000'000).
                                                                                                                                                             ^ Note
For the 100M version the decimal point is used and is necessary the way they solved the problem. The decimal point is between 1Hz and .1Hz (000'000'000.000'000).
                                                                                                                                                                                                                                ^ Note
If you send a WMF 54.32 command the AWG will change to 54.32Hz. Sending WMF123.456789 will change channel 1 to 123.456789Hz. If you send WMF0.0 clear the Frequency of Channel 1. There are bugs in their chosen solution. If you send WMF100000000. to set the AWG to 100Mhz it will display properly on the FY6900 display but send a read command (RMF) and the response will be all zeros.

You can also make the DDS Signal PC Software more-or-less work. This is how I get it to work
1 don't start the pc software
2 Plug the USB cable into the FY6900 and turn it on
3 Turn off channels 1&2
4 Turn off the FY6900 by using the button on the front of the unit
5 Start the PC Software
6 When it starts turn off channels 1&2 on the software, Delete any frequency minus signs, Don't delete decimal points but you can delete most of the zeros.
7 Turn on the FY6900 by the front button. The PC software MUST remain with (right bottom corner) MODEL: blank PORT:No Connected
8 Try turning on and off channel 1. For me the software find the FY6900 and Although none of the settings are synced they can be byt changing them on the PC.

Note that the Frequency and the decimal point work yet another way The Decimal point is between 1MHz and 100KHz.
Play with it if it runs for you and you will figure out how it works.

I hope this is helpful.

That's nice, but it doesn't help because it doesn't load what device is connected and what firmware it has. Yes, it can be controlled, but that's all, no firmware update.  |O

I had the same problem. I have 2 Toughbook laptops. 1 has Norton antivirus , the other does not. Norton must be interfering with the driver. The one without Norton works fine, but you do have to load the driver before installing the program. I have 2 of these FY6900 units which I control via a PIC chip. Unfortunately the one I bought 2 weeks ago has a fault. The frequency cannot be controlled by the USB program, all the other settings can be. I have sent some emails to Feeltech about this & asked if they have firmware that might fix this. They are not answering.

where did you find software to control it from PC? Mine arrived without CD disk...

Doesn't this work?
