Configurations options
1.9.1
UART selection for virtual COM port
It is possible to select either UART1 or UART3 to be relayed through the onboard debugger as a virtual
COM port available at the USB connector.
Depending on the selected UART, the jumpers on header J13 can be configured in two different ways.
The default configuration uses UART1 as shown in Figure 4. If you select UART3, configure the two
jumpers as shown in Figure 5 .
1.9.2
A1 and A2 analog in vs digital I/O
On the J2 socket connector, there are two pins - A1 and A2 that can be configured either as analog
inputs or digital I/Os in the 3.3 V I/O domain. By default, these two pins will be configured as digital
I/Os, as shown in Figure 6. To use them as analog inputs, configure the jumpers on pin header J26 as
shown in Figure 7. You can also use one pin as analog input and another as digital I/O as long as you
configure the jumpers accordingly. The analog level conversion down to the ODIN-W2 1.8 V I/O level is
handled by onboard voltage follower op amps.
To use the corresponding pins on the 1.8 V I/O level pin header, J23, remove the jumpers on J26 pin
header.
