which one is RX and which one is TX

The RP2040 microcontroller (U4) doesn't directly label any of its pins as RX (receive) or TX (transmit) in the provided text description. Instead, it uses general-purpose input/output (GPIO) pins.

If you're implementing a UART (Universal Asynchronous Receiver-Transmitter) interface, some GPIO pins can function as TX and RX. The excerpt [1] suggests that GPIO4 and GPIO3 can be used for UART transmission (TX) and reception (RX) respectively in the example program from the RP2040 datasheet.

However, this is a bit flexible, as different GPIO pins can be used as RX and TX pins depending upon the Pico SDK or libraries you're using.

So you would typically define this in your software based on which GPIO pins you're using for the UART interface. You can reference your software libraries' documentation or the RP2040 datasheet for more specific details on UART configuration.

In the RP2040 microcontroller (U4), all GPIOs (General-Purpose Input/Output) can be configured as digital inputs. Therefore, GPIO pins from GPIO0 to GPIO29 could all function as digital inputs.

Here's the list of the pin designations that can be used as digital inputs:

GPIO0
GPIO1
GPIO2
GPIO3
GPIO4
GPIO5
GPIO6
GPIO7
GPIO8
GPIO9
GPIO10
GPIO11
GPIO12
GPIO13
GPIO14
GPIO15
GPIO16
GPIO17
GPIO18
GPIO19
GPIO20
GPIO21
GPIO22
GPIO23
GPIO24
GPIO25
GPIO26
GPIO27
GPIO28
GPIO29

However, please note that the GPIO functionality can be configured by the user (programmer) to use appropriately as per the need of the project, unless these pins are not being used for other purposes in the specific configuration[1].
