在单片机中使用I2C通信协议的时候, 需要编写程序去模拟I2C总线的通信, 对于I2C通信协议需要补充的一点是: 在实际通信传输数据时, SCL总线拉高的时间只要大于1.5μs都能够正常传输数据. 这块128x64 OLED的裸屏是由SSD1306驱动的. 该芯片专为共阴极 OLED 面板设计, SSD1306 中嵌入了对比度控制器, 显示 RAM 和晶振...
Its simulation is lightweight, modeling the Uno’s ATmega328P chip with enough fidelity to catch logic errors, though it skips advanced protocols like I2C or SPI. I’ve used it to debug state machines, like a traffic light controller, when I needed results fast without graphical fluff. Avail...
