I've got a quick project that might best be served by an ATTiny. I've got no desire to get up to speed on Atmel tools so I thought I would troll for one of my fellow forum peeps that is already up to speed. Please let me know your thoughts.
Application
Ditching the engine driven hydraulic pump on the Garrett TFE731-3 when installing it in an L39 Albatros. I would like to do an electric pump pack but really do not like the available aircraft options.
Soooooo, I am going to do a RC Brushless out runner motor in the 3.5 KW range and drive the ESC with a micro. The micro needs to look at hydraulic accumulator pressure (0-5 v) and direct the ESC to all on or all off (with some hysteresis). The ATTiny draws about .2 ma using the on board 128 KHz osc so I can use the ESC's BEC even when the input voltage is 28 Vdc. The tiny also has a watchdog and brown out along with PWM out and A/D in (or comparator) so everything is there. Decisions are made on a very slow basis so 128 KHz on the clock is not a problem.
Any takers? C would be best for supportability going forward.
Tks,
Bill
