Dear Hantek Team,
Can you please help me with a document how to use the SPI and I2C Proptocol decoders
I could not find any information in the help file.

If I use my bench Scope with it SPI Decoder it is working prefectly as shown in PIC1
You decoder show some silly binary numbers that make no sense ,

How do I set the decoding to show Hex and the table view also does not show any data when a single capture is done and in Normal mode it shows the incorrced values and as I said I know
what the Hex values should be as I programmed my micro ou output 0xB7 and 0xBB which it does but the Hantek decoder shows some value

Hope to get some sort of help on this
Thank you
QMESAR

Hi Team

I have now tried everything with the decoder SW it not working correctly .
I have set the triggers to SDA (CH1) and CH2 on SCL and also changed it around this Trigger on SCL(CH2 ) and SDA on (CH1) it always show on the Screen the strange binary values and in the Table view the wrong hex value.
As you will see from the above screen prints the signal itself is correct the Rigol decoder decode correctly and the Hantek decode decode wrongly ,

Can you please assist to get this working I am in the middle of a SPI project for a customer .

Dear Amy
Please see screen prints
Question why is the Trigger always on the SCL line I cannot select the trigger on SDA ,if you change the trigger from edge to SPI it auto select the SCL line ?I send photos by email I canot get them to upload
Thank you

Refer this to update the FPGA software.

Both the data channel and the clock channel use the same trigger level. Please make the two channels in the same position to try.

The unit of overtime should be ns, and the software does not show it. Please set the overtime to be greater than or equal to the clock period. Such as 3000ns.
