Arduino Compatible Connector
The mapping of GPIOs and XMC pin functions to Arduino compatible functions can be found in Figure 9. The
Arduino compatible connector supports
SPI interface (SPI_xxx)
I2C interface (I2C_xxx)
UART interface (UART_xxx)
PWM signal outputs (PWM0-3)
ADC input (ADC0-5)
Interrupt input (INT0-1)

Mapping of Arduino Functions to XMC Pin Functions
The
XMC4200 Platform2Go 5V
features bi-directional voltage level shifter and therefor supports 5 V Arduino
shields. Jumper JP300 (IOREF) determines whether the Arduino shield is driven with 5 V or 3.3 V.
Analog input signals ADC0-5 are limited to 3.3 V input voltage. Primarily ADC0 to ADC3 should be used as analog
input, because there is no additional circuit connected to these pins, whereas ADC4 and ADC5 have additional
circuitry and require an input signal with lower input impedance. ADC0 is also connected to the Potentiometer for
a variable value of the analog input (optional see Table 5).
Note:
Parallel operation of I2C and ADC4 / ADC5 is not possible, because they share the same Arduino pins.
