### Packages' Patches
#### 1. For RP2040-based boards
***To be able to automatically detect and display BOARD_NAME on RP2040-based boards (RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040, GENERIC_RP2040, etc) boards***, you have to copy the file [RP2040 platform.txt](Packages_Patches/rp2040/hardware/rp2040/1.2.1) into rp2040 directory (~/.arduino15/packages/rp2040/hardware/rp2040/1.2.1).
#### 1. For RP2040-based boards using [Earle Philhower arduino-pico core](https://github.com/earlephilhower/arduino-pico)
Supposing the rp2040 core version is 1.2.1. This file must be copied into the directory:
#### 1.1 To use BOARD_NAME
- `~/.arduino15/packages/rp2040/hardware/rp2040/1.2.1/platform.txt`
**To be able to automatically detect and display BOARD_NAME on RP2040-based boards (RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040, GENERIC_RP2040, etc) boards**, you have to copy the file [RP2040 platform.txt](Packages_Patches/rp2040/hardware/rp2040/1.4.0) into rp2040 directory (~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0).
Supposing the rp2040 core version is 1.4.0. This file must be copied into the directory:
- `~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0/platform.txt`
Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz
This file must be copied into the directory:
- `~/.arduino15/packages/rp2040/hardware/rp2040/x.yy.zz/platform.txt`
With core after v1.4.0, this step is not necessary anymore thanks to the PR [Add -DBOARD_NAME="{build.board}" #136](https://github.com/earlephilhower/arduino-pico/pull/136).
#### 1.2 To avoid compile error relating to microsecondsToClockCycles
Some libraries, such as [Adafruit DHT-sensor-library](https://github.com/adafruit/DHT-sensor-library), require the definition of microsecondsToClockCycles(). **To be able to compile and run on RP2040-based boards**, you have to copy the files in [**RP2040 Arduino.h**](Packages_Patches/rp2040/hardware/rp2040/1.4.0/cores/rp2040/Arduino.h) into rp2040 directory (~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0).
Supposing the rp2040 core version is 1.4.0. This file must be copied to replace:
- `~/.arduino15/packages/rp2040/hardware/rp2040/1.4.0/cores/rp2040/Arduino.h`
Whenever a new version is installed, remember to copy this file into the new version directory. For example, new version is x.yy.zz
This file must be copied to replace:
- `~/.arduino15/packages/rp2040/hardware/rp2040/x.yy.zz/cores/rp2040/Arduino.h`
With core after v1.4.0, this step is not necessary anymore thanks to the PR [Add defs for compatibility #142](https://github.com/earlephilhower/arduino-pico/pull/142).
