#ANALOG TO DIGITAL CONVERTER CODE HOW TO#Īctual sound waves consist of continuous variations in air pressure.1 Analog to Digital Converter AN Application Note Introduction This application note describes how to use the EFM32 Analog to Digital Converter to convert an analog input voltage to a digital value.
Many aspects of the ADC, including inputs, references and the different operating modes are described.
This application note includes: This PDF document Source files (zip) Example C-code Multiple IDE projectsĢ 1 Analog to Digital Converter 1.1 Introduction.the world's most energy friendly microcontrollers The EFM32 ADC is a Successive Approximation Register (SAR) architecture.Ĭalibration routines for offset and gain are also included. The maximum resolution is 12 bits, and one million samples per second can be achieved at this resolution. The integrated input mux can select ADC-input from 8 external pins or 6 internal signals. With the help of PRS and DMA, the ADC can operate without CPU intervention, minimizing current consumption or allow the core to do other work.
The ADC can be clocked at different speeds, and run at different warm-up modes to reduce the energy consumption even further. This application note shows general operation and usage of the ADC. In addition, advanced features and power saving techniques are described.
Software examples of ADC operation both with DMA and PRS are included. Offset and Gain Calibration of the ADC is also described and included in the software examples. #ANALOG TO DIGITAL CONVERTER CODE SOFTWARE#įor extremely low power periodic ADC sampling, a software example which enter EM2 between each ADC sample is also included.
