When will you offer the BeagleMIP?
about 6 years ago
I have just started a github MPLABX project using a 24F as a secondary processor to control this board. It is a work in progress, but I have some time off after the 4th. The theory is that the 24F will expose a pin to the main CPU as a signal that a button has been debounced. The main CPU will communicate via SPI to the slave to set LEDs, leg brightness, and read the switch states.
some will not like it because it is object oriented, but you get what you pay for (free)
I have no idea when it will be finished, but if someone wants to design or code the SPI interface, then have at it. The SPI interface does not have to be OOPs, but it has to be "clean code" so that one can read it and maintain it.
Next rev of the board should have an optional 2N7000 placed on the LED_GND[1-4].
This is useful to rapidly cycle through the LED columns to reduce total current
I don't know of many controllers that can sink many ma of current.
And it would be useful to have optional series resistors because no RGB led has the same luminosity, forward voltage, current specs for each color. I'll be doing an ARM SPI driver with MCP23S08 (switches) and MCP23S17 (or 74lv154) for LED. Has anyone measured the debounce interval yet?

Ok, I will just complete the installation of the new SparkFun "you will become irresistible to women" module. Hum, is it the blue wire or the red wire, well, given your track record, we shall soon know!

"Pair", you keep using that word. I do not think it means what you think it means
I am happy that you are now bicycle commuting. But you know, we do have a shower.
You know when you sit on a chair, lean back on two legs, and you almost fall over but at the last second you catch yourself? Well, I feel like that all the time. How is it going with you?
You think you could warn me when you are about to sneeze?
I think the boss said "pair" not "chair"!
No public wish lists :(
