interrupt on OCR0RA internally - AT90PWM3b AT90PWM3B has 4 PSC timer register (two output, two deadtime). I want to interrupt when OCR0RA is "on" so the ADC can measure current over a shunt. How would you do this... |

can you do two single adc conversion after each other? Can you start a conversion (ADCSRA |= (1<<ADSC)) wait for the interrupt, read the data, and then (after the interrupt) start a new conversion? |

Interrupts with AT90PWM3B I'm trying to get a interrupt when the PSC go high. It will then activate a ADC to measure current. The feedback from the shunt is connected to PSCIN0 pin (and the adc). Here is... |

To low voltage on a pin. [solved] I'm trying turn a LED on/off with 0.5s delay, It works but I barely see the light. I read only 2V out of the pin. I check the supply and it gives a steady 5V. LED is in series... |

high()/low() functions for C? In assambler you can use high/low functions for split a 12bit int to two 8bit registers. But how do you solve this in C? |
