FeelTech FY6600 60MHz 2-Ch VCO Function Arbitrary Waveform Signal Generator

soundtec:
I discovered the way the left right arrow buttons work while in wave select mode , to change bank from preset to arb thats a handy feature.

Everything just feels more snappy now with the new code , its not like the original s/w where the machine seems to have a little yawn before doing what its told , same can be said for the new pc front end software , when you change something on the pc screen theres no decernable delay in whats taking place in the unit itself.

One thing I've never liked much about the F'tec was the need to  press the channel button twice  in order to mute or switch on the output channels , if channel select(to top of screen)  and on or off could happen in a single key stroke it would be much handier for cueing and mixing the outputs for test signals or even if the unit was used in a musical context . 

So apart from the frequency select mode issue on the encoder push button  and the extra zero's that appear in front of the selected field which I thought were unessesary ,I cant fault one single other thing in the new UI , it has a definate edge in terms of intuitiveness of usage compared to Ftec 3.2 , I also like the way the parameters visible and available to modify changed depending on the waveform in use , it helped me focus better on the job at hand .

The new measure ,mod and sweep pages are a revelation compared to 3.2 , and full independent mod/sw  features on both channels  not to mention  my formerly 15mhz machine now goes up to 62.5mhz   :palm:
you have truly spoiled us sir !

The firmware  upgrade was easy , Id had the St32 programmer software on my pc before so once I got the header implanted,3 wires  and the driver clicked  in  ,once Id ok'd overwrite warnings , took about 30 seconds ,the machine rebooted itself , and it runs off the new UI without a glitch since.

Fremen67,

Do you have an estimate when you will have a version that will work with a FY6800. I have a 60mhz FY6800 board version 1.7 FW V1.7.1. If you need help testing let me know. Also what LCD are you using with the bluepill.

Thanks
Mike

JTCK to SWCLK, JMS to SWDIO and GND … to GND. Keep the 2 ribbons connected as the power supply will come from them.
In short you switch on the FY6600 , launch the STM32-utility, click Target/Program&Verify,  select the .hex file and start!
You will find the software for the ST-Link here: https://my.st.com/content/my_st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-utilities/stsw-link009.html

I just flashed my bricked V3.0 - worked like a charm! Thank you very much for these efforts!
Still didn't get anything from Feeltech - i owe you a beer at least  ;)

Here's what i had before your cure, and what i have now:

I completely forgot to describe the new UI funtionnalities but it seems that you discovered them all by yourself...
For the others who do no have it in front of them:

Waves:
- First click on Wave button change to edit mode but does not change the current selection (big pain with the original firmare ...)
- Encoder +: change current wave to the next one
- Encoder -: idem for previous one
- Right Arrow: go to Arb1 wave
- Left Arrow: go to Sine vave
- Encoder click: end edit mode

Numerical parameters (frequency, ampl, ...):
- First click on corresponding function key change to edit mode
- Right, left arrows: select next or previous digit
- Encoder +/-: inc/dec selected digit
- Encoder click: select default parameter value (0V for Offset, 50% for Duty, 0° for phase, etc ...)
- Second click on corresponding function key end edit mode

Text parameters (sweep source, source direction, etc ....):
- First click on corresponding function key change to edit mode
- Right, left arrows, Encoder +/- : select next or previous choice
- Second click on corresponding function key: show possible choices for parameter on function keys for direct selection
- Encoder click: end edit mode

OK I will do it!

I will change the behaviour of the encoder click when on frequency (revert to defaut value at the moment). It's in my todo list, before the rounded corners but after the system menu  ;)
As for the leading zeros appearing on edit mode, it has been done on purpose to ease digit selection but other solutions could be used later on (like adding zeros only to the right of the cursor).

Thanks a lot for the compliments  :) (Sweep on both channels but modulation on channel 1 only as it is done by the FPGA...)

Some days ago I was on the idea to release only the bluepill version to test the functionnalities and now the front panel version is already installed on some units... I even did not finished to test all the programmed GUI functions. :scared:
You are the Indiana Jones of the FY6600 ! No fear!

I found and corrected yesterday 2 bugs in the version you have. The counter reset function did not work anymore and the encoder driver had some issues when activating a sweep function.
I will give you another version in some days.

Hi Mike,
I have to focus on finishing the remaining menus (at least system menus) before switching to FY6800. The first step will be to analyze the protocol between the front panel and the FPGA to see the differences with the FY6600. I suppose that it will not impact a lot the new firmware (this plus some different keys on the 6800 front panel) but I can't be sure now. I will say one or two months... I will anyway do the modifications for the 6800 and the 6900 in parallel to same time.

The new firmware will be a big improvement for the sweep function of the FY6800 as they ruined it. Try this:
connect an oscilloscope and sweep a 0V DC wave from -1V to +1V at 0.01s or even at 0.1s sweep time. The ramp obtained is a disaster on my 6800 which is V1.6. May be different on the V1.7 but I have doubts.

In the meantime if you have a way to backup the flash eeprom on the main board that would be interesting for me.
The LCD that would work for the bluepill is a ILI9341 with SPI.
