IO Mapping

The Raspberry Pi Pico 2 exposes a single Peripherals module (ModuleId 1704) under the device node. All channels below appear automatically in the CODESYS I/O mapping view once the device is added to your project — see Getting Started.

Digital Inputs

Channel	Parameter ID	Type	Default mapping
Input 0	1000	BIT	IN0
Input 1	1001	BIT	IN1
Input 2	1002	BIT	IN2
Input 3	1003	BIT	IN3
Input 4	1004	BIT	IN4
Input 5	1005	BIT	IN5
Input 6	1006	BIT	IN6

Digital Outputs

Channel	Parameter ID	Type	Default mapping
Output 0	2000	BIT	OUT0
Output 1	2001	BIT	OUT1
Output 2	2002	BIT	OUT2
Output 3	2003	BIT	OUT3
Output 4	2004	BIT	OUT4
Output 5	2005	BIT	OUT5

Analog Inputs

Channel	Parameter ID	Type	Default mapping
Analog 0	3000	WORD	AN0
Analog 1	3001	WORD	AN1
Analog 2	3002	WORD	AN2

Onboard LED

Channel	Parameter ID	Type	Default mapping
LED	4000	BIT (output)	LED

System

Channel	Parameter ID	Type	Access	Default mapping
Temperature	5000	REAL (input)	read/write	TEMPERATURE
Vendor	393218	STRING	read-only	'nexo S.r.l.'
Model Name	393219	STRING	read-only	'IO'

Temperature reads the RP2350A’s internal die temperature sensor in °C.

Note

IN0–IN6, OUT0–OUT5, AN0–AN2 and LED are the same channel set exposed by Raspberry Pi Pico 2W — the two boards are I/O-identical, the W variant only adds WiFi configuration parameters.

See ST Examples for sample code using these channels.
