Class _ada: 12-bit analog to digital converter

This class is used by:

• STM32F103: adc0, adc1

ST Documentation:

• AN3116 - ADC modes and their applications
• AN2884 - How to get the best ADC accuracy in STM32 microcontrollers

Features

• 12-bit resolution, left or right adustement of the result
• ~1 μs conversion time
• Up to 16 multilexed single-ended input channels
• Internal temperature sensor input
• Internal 1,2 V bandgap input
• Vref-..Vref+ input voltage range
• Single / continuous / scan / discontinuous conversion mode
• Self calibration
• Analog watchdog
• Channel-by-channel programmable sample time
• Conversion on external trigger
• DMA
• Interrupts
• Temperature sensor

Note

The ADC input clock is generated from the PCLK2 clock divided by a prescaler and it must not exceed 14 MHz.

Relatives

• (ADC,irq): conversion completed IRQ

Interface

• get the number of bits of the ADC:

HW_BITS(ADC);
