I have a simple ATTiny project and would prefer not to take the time to get up to speed on the Atmel environment. Is there anyone in the WPB Fl area interested in a simple project? I'm looking for coding in C. The task is to monitor a voltage then switch on/off a (fixed duty cycle) PWM based on hysteresis. Side elements are watchdog and brownout (if available). The 128 KHz onboard osc. will be sufficient as I'm interested in sub 1 Hz system control and low power consumption. End application is maintaining an accumulator hydraulic pressure where a brushless (RC style) DC motor with an electronic speed controller (thus the PWM) is turning a gear style hydraulic pump. The pump switches on at one pressure and off at the set point. There needs to be a delay on power up and a watchdog to prevent the code from going off into space :) Thoughts welcome.
