Consult the Bascom help (start Bascom help, choose find and type 'AVR internal registers') and the AT90S2313 datasheet (table 1, page 15 and 16) Reading a rotary encoder or keyboard on interrupt Rotary encoders and small keyboards are typically read on interrupt. Now you know the basics of ADC let us see how we can use the inbuilt ADC of AVR MCU. The ADC is multiplexed with PORTA that means the ADC channels are shared with PORTA. Bascom bietet dafr den HighlevelBefehl GETADC an. GETADC stellt zuerst den abzufragenden Pin ber den Multiplexer ein und misst danach die dort angelegte Spannung mit dem ADC. Du musst dich selber um nichts mehr kmmern. Du solltest aber auch wissen, dass GETADC kein Wundermittel ist. Microcontroller understands only digital language. However, the inputs available from the environment to the microcontroller are mostly analog in nature, i. , they vary continuously with time. The one used by AVR is of the succesive approximation ADC kind. The following is a simplified scheme of the ADC. At the input of the ADC itself is an analog multiplexer, which is used to select between eight analog inputs. Tutorial on how to use ADC (Analog to Digital Converter) in AVR. Explained using LM35 Temperature Sensor and Atmega32 ADC. In order to do that we need a device called an ADC (Analog to Digital Converter) (60 Celsius degrees as an example).
