MikroElektronika EasyMX PRO v 7 |
It is worth noting for reference, some of the stuff that is out there for development at the level beyond what a Raspberry Pi would do.
For instance, from Serbia -- yes, Serbia, we have the US$ 169 MikroElektronika EasyMX PRO v 7, and this would go well with say the Rigol DS 1052E US$ 330 - 400 or so digital storage oscilloscope with spectrum analyser features. The EMP comes with an on-board programmer-debugger, an LCD screen -- that's a cheetah being shown -- and it takes a family of processor cards. There is a buzzer, temperature sensor, a USB bus interface as well as Ethernet, and it also interfaces with the automotive industry standard CAN bus.
The ARM of course, thanks to low power consumption, is used in a high proportion of cell phones and the like, so it is the most common processor family at this level.
And if you need a lighter duty, light on the wallet USB resident oscilloscope, it may be useful to look at something like the DPScope SE.
