Help on the program. Calibration.
« on: October 06, 2018, 06:51:20 PM »
Help with the program:
1) Does the software generator work?
2) "Setting-Termal" work?

Hardware generator: the "default" button does not reset the mode.
The "dc" mode is no change to "voltage".
The value "offset" is incorrect. According to the program 1 volt, in reality 0.91.
The "custom" generator mode did not work for me.

–°alibration:
1) Calibration VCC_DIG. ( Prog -> Real) : 1.5 -> 1.49; 2 -> 1.93; 3 -> 2.84; 4 -> 3.68
The measured value is lower than in the program.

How to make manual calibration of the analog channel?

1 & 2 it should both work. Software generator is for simulation purposes only.

For DC mode you have to adjust Offset setting, not Voltage.
Custom mode analog generator should work. Did you use the custom file: "/data/signal/custom.signal"?

Generator offset should be calibrated. You can change calibration settings manually in "data/startup/calibrate.json".

Yes, there is a bug in FPGA firmware for VCC_DIG output. Firmware is not setting both of the digital variable resistors. This will be fixed in new version. You can also change "generatorStep" manually in "data/startup/calibrate.json"

When are you planning to release a new version of the program?
