More CRO 'scope demos, but with a Microchip DM240013-2 on discount

Folks

I was looking to do one of the Youscope type demos last week, and in so doing was looking for a microcontroller to fit the bill that wouldn't need many external components like R-2R ladders etc. After a bit of searching, I chose a PIC24FV16KM202, for which there's also a micro demo board, on 35% discount on MicrochipDirect  (GBP12.35) and priced at Farnell at GBP11.66. This includes an onboard USB debugger.

The chip itself has some interesting features, including dual 8 bit DAC, and will run off 5V if that's what you want.

So I wrote some code over the weekend to reinvent the wheel a bit, you don't even need a soldering iron, just an old school CRO with X-Y mode. The code works either with the old MPLAB IDE (8.92) or MPLAB X (v2.26), and will compile and run with the free version of the XC16 compiler.

Very nice.

Nice job, and very nice scopes! Two of my favorites!

Dare I suggest that those purchasing decisions may have been slightly swayed by a certain youtube channel you may know?

I had a 2465B for some years, but sold it about five years ago, a decision I since regretted, so recently I got hold of a 2467B.
