Re: Quisk conf.py Si570 QRP2000

Hi Yves,
Do you want to tune the SI570 VFO from Quisk, with a certain IF frequency offset?
Yes, exacty, eg 3.650(frequency to display on Quisk)+10.712 (IF)=14.362 (frequency of the QRP2000 signal generator)
Do you want to tune the SI570 via USB or via I2C? In the QRP2000 (SI570) signal generator an Atmel ATTiny85 Micro-ControllerATMEL connects to the PC via the USB port.
I have checked the ?hardware_usb.py in the configuration menu and set the IF in Bands as if the IF were a transverter but no luck. In Softrocks I believe the frequency is multiplied by 4 to tune, here I would just need a simple VFO (I don't even need I and Q), something that is more basic.

Hi Franco,
I'm not sure to understand the problem, could you explain a bit more what you want to achieve??

I think such functionality should be implemented in the Quisk hardware file, see the documentation for "ChangeFrequency(self, tune, vfo, source='', band='', event=None)".
I did that with I2C control of the SI570.
For USB control of the SI570 look in the softrock folder, file?hardware_usb.py; but I have no experience with it.
