Re: Problems with the UART decoder

Can you repeat the test with a teensy board.

I f this gives the same result I suspect the internal scope oscillator is about 2.2% off.

According your .psdata the measured baudrate of the signal is 117.7 kbps

Re: Problems with the UART decoder

Now the key question which of the timing is off, the scope or de Arduino. I guess the Arduino. Can you make a .psdata file of something with a exactly known frequency at the highest sampling rate possible with your scope. Be sure you set the number of samples to the max (100MS) as in image below 202...

Re: Is it possible to make the Picoscope software use complete data for math channels and measurements?

I think there is a misunderstanding. The math data is always calculated by the windows PC, but there are 2 situations. 1. live view (the math channel data is calculated and shown from the downsampled data) this is because during live view (in all situations ?) there is only downsampled data send to ...

Re: Problems with the UART decoder

Looking at the data again it could also be 7N1 witch makes more sense.

As of why it is not the default 8N1 needs investigation.

can you try with
Serial.begin(115200,SERIAL_8N1);

Re: GUI Refresh rate depends on Time/Dev in Win10, witch is really annoying if you want to do sub Hz mesurement.

Are you using the scope in streaming mode with this slow timebase ?

Tested this with my 3403D scope and I can not reproduce your problem.

Re: Math tools and 12 bit resolution

Do you have a .psdata file.

It looks like black and blue are both math channels.

Re: Problems with the UART decoder

You have initialized the port with no stop bits.

See attached and fixed settings.

Re: Problems with the UART decoder

Some hints on setting up the right way
1st set your scope to +/- 10V instead of 5 because you have overvoltage and the decoder can have problemens with overvoltages.

2nd your signal seems te be inverted so you need to setup as shown below.

Re: Difference between A and B

You can expand the y-axis by clicking on the smal box at the bottom

so if you set the scale to 10 you can see the difference
Remember this a 8 bit scope.

maybe you can do something with the math channels.

Re: Measurement between cursors on Voltage scale?

Yes it works only on the horizontal ruler, (time) and not on the vertical ruler (V)

What are you trying to measure on the wave ?
