which dev board/microcontroller to purchase

[rhb]

Dev boards have become cheap because the Arduino scared the pants off the other vendors.  TI has repackaged the Arduino IDE as Energia.  I suggest getting one or two of several types.  You want fast ADC?  LPC has the LPC-Link2 programmer which you can use as a target board.  The LPC 4370 has an ARM and an 80 MSa/S 12 bit ADC.  And the Link2s are $20 from Digikey.  It should be possible to make a DC to 30 MHz waterfall display screensaver for a 4K monitor with 10 KHz resolution.

You might want to consider an Arduino M0 (pro) or MKR1000, giving you the advantage of a not too steep learning curve with the Arduino IDE + libraries and later on the nearly unlimited possibilities of Atmel Studio and real (JTAG) debuggers. Note that the MKR1000 does have a JTAG header, while the MKR zero for example does not. Both the M0 and M0 pro do have a JTAG header, but the Pro version has a USB debug port so you don't have to buy a J-Link or ST-Link.
It uses an Atmel/Microchip SAMD21 with an ARM M0+ based MCU.

If you don't fancy the Arduino ecosystem to start you might as well go for a Cypress PSOC4 (pioneer) board or an STM32F0 Nucleo. I personally like the Cypress IDE, but YMMV. Both feature a USB debugger, but the STM board has a ST-Link (= J-Link).

Thanks everyone for your advice!  I think I am going to go with he arduino and a psoc 4200.  I will start there and see where it takes me.

After getting too irritated by advertizements for some rotten fruit brand I forgot what I wanted to post here.

Sorry for that.
