Hmm that was not a very nice comment.... He clearly demonstrates an excellent summary of the product and I really value this review. I don't own a scope, but could use one for basic testing - and this has 100% helped me with my decision. Like he said "It's NOT a substitute for a real scope" ;)
@mikeselectricstuff12 жыл бұрын
I noticed that - not sure - could have been that the MCU is doing more in different modes, or maybe using internal RC osc.

Like I said it is NOT a substitute for a real scope, it's for situations where you need something smaller & more portable, like in-the-field testing & faultfinding.

Soft cores aren't always good value, as they use relatively expensive FPGA fabric compared to the optimised, dedicated silicon of a seperate MCU. This is why most FPGA vendors are now putting hard ARM cores on their chips. As to using two ATMegas, that's just plain bizarre!

that very yellow+blue OLED display is all over ebay. it's stupidly cheap, only a few dollars. the catch is there's no power supply on it so you have to provide your own (and it had that tab connection). The FPGA is amusing. The entire scope could've easily been handled IN the FPGA itself using soft cores and stuff. The code could easily have fit in blockRAM.
