Pico-Kubik, a tiny quadruped robot

I'm building a very small spider-like robot, and VoCore seems to be the perfect choice for its brains. I didn't want to muck about with PWM drivers, so I decided to make a simple servo controller out of an Arduino Pro Mini, and I plan to communicate with it from VoCore trough TTL, from a program running on Micropython.

You can follow that project here: ... uped-robot

However, I can't seem to be able to get /dev/ttyS1 to work. Do I need to change something in configuration somewhere to make the other UART (not the one on which the console runs) available?

Ok, I found telling me how to enable the second UART. Turns out /dev/ttyS1 is used internally and is not the second UART.

I have all parts of the robot connected and working, and some simple example programs prove, that it works. Now I need to work on real software for it, and maybe a better chassis.


By the way, I noticed that sometimes (not sure why, weaker battery maybe?) VoCore boots with less memory available than usually:

Code: Select all
root@OpenWrt:~# free
             total         used         free       shared      buffers
Mem:         13312        12712          600            0          804
-/+ buffers:              11908         1404
Swap:            0            0            0

Any idea why that may be?
