 
this is SVN684 ESR tester firmware for AY-AT Colour-TFT  hardware ONLY.

this is for all the guy's at BadCaps forum.

------------------
what's new:
fixed a bug in frequency-generator

see here:

mains reference frequency's in frequency generator.

based on latest SVN version


after programming, you need to calibrate the unit. (preferably twice)
you need something to short all 3 inputs,
and an accurate capacitor between 100n and 1uf - i recommend a 220n polyester cap.
-
you also need a good stable capacitor between 10 and 30nF to calibrate the new small inductor mode.
if you dont have one, just ignore the cal message till it times-out

to test small inductors you MUST connect the small cap used to calibrate the unit in parallel with the inductor.
----------------------
SamplingADC is now enabled by default. The calibration procedure asks 
for a capacitor for L-measurement with the message "Cap for L meas?".
You should use a capacitor value between  10nF and 20nF for future 
measurement of little inductances. If your coil is only detected as 
resistor, or with little inductance, you should connect this known 
capacitor (10nF-20nF) parallel to the coil and repeat the measurement. 
The measurement is now possible between any test ports.
You can only measure little capacitors between TP1 and TP3!
