OLED屏是一种常见的显示屏，下面以0.96寸OLED模块为例，用IIC的DMA来实现OLED屏幕的刷新。 采用DMA方式不需要程序一个个字节发送，通过启动DMA自动完成整个屏幕的刷新，可以节约大量的CPU时间。 该屏幕分辨率为128x64，每个点占用1bit，于是整个显存占用128x64/8 ...

OLED是非常常用的显示设备，可以由4线、3线的spi驱动，也可以使用2线的IIC来驱动。百问网提供了spi_OLED的驱动例程，这次使用IIC来驱动，并且使用基于面向对象的编程来实现。 1.配置IIC，打开RASC后，在栈中增加rau_master_I2C，并设置channel为0b20即通道2，选择SCL为P112 ...

这款基于 Arduino 的双模式科学计算器是一种多功能且高效的工具，可用于基本和高级计算。在普通模式下，它用作标准计算器，通过 4×4 键盘执行加、减、乘、除。结果清晰地显示在 OLED 屏幕上。按钮开关可在模式之间无缝切换，以增加灵活性。 本文引用地址 ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

Anyone who follows my articles here at TweakTown knows that I am a sucker for new Arduino-compatible development kits, and I especially like the micro-sized boards that are easily hidden inside ...

Those of you that enjoy using the Arduino platform to build electronic projects, a new WifiDuino device which has this week launched over on the Indiegogo crowd funding website, ma be worth more ...
