The datasheet says: Free Running mode is selected by writing the ADFR bit in ADCSRA to one. The first conversion must be started by writing a logical one to the ADSC bit in ADCSRA. Now in the Register Summary there are given 2 adresses for ADCSRA: $06 ($26). Which one should I use? The bits to write are: â?¢ Bit 5 â?? ADFR: ADC Free Running Select â?¢ Bit 6 â?? ADSC: ADC Start Conversion If I want to set bit 5 and leave the other bits unchanged, what should I do? My guess is: 1. Read the register value 2. OR this value with 0b00100000 3. Write the result to the register Is this correct? Regards, Pepe | ||
