Serial and Simple blink sketch pico2

[ledsynth]

Can anyone confirm if this is working with pico2
nothing seems to run

#include "Arduino.h"
#include <Adafruit_TinyUSB.h>
#include <tusb.h>
#include <SoftwareSerial.h>

//sketch works with pico not pico2

// SoftwareSerial for debug output (RX: GPIO26, TX: GPIO27)
SoftwareSerial myDebug(26, 27); // RX is unused

void setup() {

pinMode(25, OUTPUT); // onboard LED
// Serial.begin(230400);

Serial1.setTX(0); // GPIO0
Serial1.setRX(1); // GPIO1
Serial1.begin(230400);

Serial2.setTX(4); // GPIO4
Serial2.setRX(5); // GPIO5
Serial2.begin(230400);

myDebug.begin(230400);
myDebug.println("Debug UART started");

// Start MIDI UART output
// MIDI_UART.begin(31250); // Standard MIDI baud rate

}

void loop() {
digitalWrite(25, !digitalRead(25));
Serial1.println("Serial1 "); //working
Serial2.println("Serial2 "); //working
delay(500);
}

Make sure you set the board to Pico 2 in the menus. The Pico and Pico2 executable formats are very different.

Under Arduino IDE code runs on pico2. if I build the code in Platformio as Pico2 it doesnt run maybe my ini file is wrong

[env:pico]
platform = https://github.com/maxgerhardt/platform-raspberrypi.git

;for PICO2
board = rpipico2
board_build.mcu = rp2350-riscv

;for PICO
;board = pico

framework = arduino
board_build.core = earlephilhower

build_flags =
-DUSE_TINYUSB
-DUSE_TINYUSB_HOST
-DCFG_TUH_ENABLED=1
-DCFG_TUD_ENABLED=0
-DCFG_TUH_MIDI=1
-DCFG_TUH_CDC=1
-DCFG_TUH_MSC=1
-DCFG_TUSB_DEBUG=1

lib_deps =
adafruit/Adafruit TinyUSB Library

Any reason you're hard-specifying the board_build.mcu If you drop it, does it build and run ion ARM mode?

[maxgerhardt]

I don't understand this ini file at all-

• you enable TINYUSB_HOST
• explicitly try to override the USB device stack (TUD_ENABLED = 0)
• Enable a bunch of USB host support for midi, cdc and msc devices
• Then your sketch uses nothing of that and only the regular hardware UARTs and a software UART?
• you should not add lib_deps =adafruit/Adafruit TinyUSB Library because the Arduino core already has it builtin
• RISC-V mode used for particular reason?

If you just say

[env:pico] platform = https://github.com/maxgerhardt/platform-raspberrypi.git board = rpipico2 framework = arduino

with

#include "Arduino.h" #include <SoftwareSerial.h> // SoftwareSerial for debug output (RX: GPIO26, TX: GPIO27) SoftwareSerial myDebug(26, 27); // RX is unused void setup() { pinMode(25, OUTPUT); // onboard LED // Serial.begin(230400); Serial1.setTX(0); // GPIO0 Serial1.setRX(1); // GPIO1 Serial1.begin(230400); Serial2.setTX(4); // GPIO4 Serial2.setRX(5); // GPIO5 Serial2.begin(230400); myDebug.begin(230400); myDebug.println("Debug UART started"); // Start MIDI UART output // MIDI_UART.begin(31250); // Standard MIDI baud rate } void loop() { digitalWrite(25, !digitalRead(25)); Serial1.println("Serial1 "); //working Serial2.println("Serial2 "); //working delay(500); }

Is should just work.
