Interest in tinysa without display

 

Dear all
I would like to integrate a spectrum analyzer to a laser oscillator for supervising the quality of a laser beam via photodiode. This photodiode will be routed to spectrum analyzer over a TIA. The result will be send to PC application or to a microcontroller to make further actions. Because the SA is integrated in a device there is no need for a display. My questions are:
1. Is possible to run tinysa without display to save power?
2. I guess the protocol regarding extraction of data out of sa is open and documented?
3. To readout data is it possible to make access over rs232 not USB? Is there a native USB communication on this board or is a rs232 to USB converter?
4. I guess that this problem with dual peak is solved for this type of device?
Best regards

Not without modifying the SW, which you can do yourself
?

See:?https://tinysa.org/wiki/pmwiki.php?n=Main.USBInterface
?

The USB interface is native. There is also RS232 HW available on the PCB but currently does not fit in FW so it is commented out but you can remove unneeded parts and enable the serial interface
?
4. I guess that this problem with dual peak is solved for this type of device?
No double peak with tinySA
?

Simon,
You could probably surgically disable the display backlight to save power (without any firmware change).
