Hello BenF
The firmware v3.40 Benf is not working well on the Nano V2, contains noise … the larger the scale v / div contains more noise.

thanks

The firmware v3.40 Benf is not working well on the Nano V2, contains noise … the larger the scale v / div contains more noise.

In order to verify that your Nano is working ok, a good start is to test without USB power (using the internal battery) and the probe connected to the frequency generator with a 1 kHz test signal. You should then see an image similar to this:

Is the source for this about, or will it appear in the svn repo? Apologies if I just haven’t looked in the “standard” place.

Thanks!

Hello BenF

With the old firmware v2.4 both could measure 80Vpp!
Now we can measure how many Vpp with the current firmware BenF v3.33 and v3.40 ?
With this new firmware BenF v3.40 can measure 110v and 220v AC?

Thanks

The source for V3.11 and related project templates for IAR 4, IAR 5 and GCC is available from google code:

Max Vpp with the standard 1x probe is 80 Vpp (10V/Div) and 800 Vpp with a 10x probe (100V/div). There is now an additional 0.2V/Div for 10x probes, but apart from this, choice of attenuation is unchanged.
