This is a port of Arduino to the RP2040 (Raspberry Pi Pico processor) and RP2350 (Raspberry Pi Pico 2 processor). It uses the bare Raspberry Pi Pico SDK and a custom GCC 14.2/Newlib 4.3 toolchain and ...

本期活动发放的开发板是Arduino Nano RP2040 Connect，这块主板上的主芯片是树莓派的RP2040。 RP2040是支持两路UART的。 可知这一路硬件连线实际使用的是RP2040的UART0，但是在Arduino IDE中如果想使用这一路硬件的话，需要使用对应的代码对象Serial1。 Arduino Nano RP2040 Connect的 ...

Client SDK to connect with ThingsBoard IoT Platform from IoT devices (Arduino, Espressif, etc.) ...

本期活动发放的开发板是Arduino Nano RP2040 Connect，这块主板上的主芯片是树莓派的RP2040。 在尝试使用nano控制外部继电器时发现实际硬件并不是任意一个IO都适合，就整理资料如下。 先说结论：在nano板上，适合控制外部的RP2040的IO有9个。 剩下的是可以在主板排插引 ...

Couldn’t a microcontroller talk to a VGA card too? Of course it can, and [0xmarcin] is here to show how it can be done with an Arduino Mega. The project builds on the work of another similar one ...

Arduino is a popular open-source development board used by engineers, hobbyists, and makers to develop electronic projects and prototypes easily.
