If you do embedded firmware and hardware, www.ee101.com now has a $29 Maker version of their EE101 Insight-Pro with real-time current measurement, firmware debugger, logic analyzer, oscilloscope and I2C spi and UART decoding. I use the Pro version every day and it’s a really helpful tool.

 

This is a Cypress PSOC 5LP. You have to buy the board, $ 10,. and the $29 is for the
firmware which you program the board either with PSOC Creator or Programmer,
either free -

Not sure if they sell the source or the binary to burn into board. I assume it includes
PC GUI that it communicates to ?

Yes, that is a powerful little board for just $10. They give you the binaries to program it with and it runs their analyzer software on both PC and Mac.
