2.3.12 ADC
The Mini210S utilizes 6 ADC channels that the S5PV210 has for different purposes:
-
AIN0 is connected to an adjustable resistor W1
-
AIN1, 2, 3, 4 and 5 are connected to CON6 which includes other GPIOs as well
The S5PV210’s AD conversion can be configured as either 10-bit or 12-bit.
2.3.13 PWM
The on-board buzzer is controlled by PWM0, the diagram is shown below. PWM0
corresponds to GPD0_0 which can be configured as PWM output via software or used
as a GPIO.
