Firmware upgrade question

Thanks for the info I’ll try that. So what’s the difference with pauls firmware 1.5 and what I will now call the official seeedstudios firmware?

I am concerned however as I didn’t realise I was buying some sort of clone. I bought it on ebay as a DSO nano 201 it has E-Design on the back, I just assumed they were all the same. I didn’t even look at the seeedstudios website as I thought I had enough info from the seller to at least decide to buy.

Is there a difference in the design of the Seeed and E-Design versions as I found a Sparkfun forum post saying they were the same. I can’t compare the two circuit diagrams as I can only find the Seeed version online.
