Analog to Digital Converter (ADC) on ATMega8535
am in پاسخی ارسال کرد برای یک موضوع در زبان تخصصی برق
ATmega8535 provides the ADC with a resolution of 10 bits. ADC is connected to 8 channel Analog Multiplexer which allows formed eight single-ended input voltage is ADC0 to ADC7. Can also be configured into seven differential input channels with ADC1 as the common terminal and the other negative a...-
