Gruvin board vs erSky9x Board - whats the difference

Post by hamburger »

aehm,
does ERSKY9x stand for a firmware or is it the label of a replacement hardware as well?
I fould the gruvin hardware board (v4.1?) mentioned somewhere.
How do these two compare, please?

There are two different boards in the mix.

ersky9x is both a new firmware & board being done by the er9x team.

xxxx (no name yet?) is a new board being done by the gruvin team to run their new gruvin system.

The boards have been designed independently so are pretty much completely different.

It will be interesting to see which one becomes the lead system in the next year or two!
Slope Soaring, FPV, and pretty much anything 'high tech'
...........if you think it should be in the wiki.. ask me for wiki access, then go add it!

AFAIK the Gruvin board is using an ATMEGA2560 AVR device. This is compatible with the compiler used to compile the standard (alternative) software, and the inbuilt peripherals are very similar, if not the same, as the ATMEGA64 used on the stock board. The ersky9x board uses an Atmel ARM processor. This requires a different version of the GNU compiler, and the inbuilt peripherals are different, so require new, low level software drivers. Drivers for many of these are in the early development versions of the ersky9xsoftware.
The Gruvin board appears to be available now, while the ersky9x prototype boards are being tested, and a revised version of the hardware is about to be made.

You guys pretty much have it. The Gruvin V4.1 board (the current one) has the ATMega2560 100pin 256Kb device. Same tool chain as mentioned. Less of a leap software wise than the ARM board, so we haven't had all the hard low level work to do, but not as quick a processor. Overall hardware feature list will be similar on both once completed best I can tell.
