在Arduino编程中，理解和使用数据类型是关键步骤。其中，uint8_t、unit16_t和unit32_t分别代表不同长度和数值范围的无符号整型数据。首先，我们来了解一下uint8_t。它实际上就是unsigned char类型，用于表示一个无符号的8位整型数，其数值范围从0到255，占用一个字节的内存空间。紧随其后的是unit16_...
二、实验器材 UNO 控制板:1 块 1602 液晶显示器:1 块 面包板:1 块 面包板跳线:若干 三、连线示意图 图8-1 四、硬件连接图 图8-2 五、硬件知识要点 本次试验使用arduino 直接驱动1602 液晶显示文字 1602 液晶在应用中非常广泛,最初的1602 液晶使用的是HD44780 控制器,现在各个厂家 的1602 模块基本上都...
unit8_t led_state = LOW; unit8_t btn_pre = HIGH; void setup() { pinMode(btn_pin, INPUT_PULLUP); pinMode(led_pin, OUTPUT); } void loop() { //poll for button push unit8_t btn_state = digitalRead(btn_pin); if ((btn_state == LOW) && (btn_pre == HIGH)) //电位下降 {...
我们知道在MCU(Microcontroller Unit)中运行的是CPU硬核,比如Intel的8051核,ARM的Cortex-M核,Arduino板上用的AVR核等,各大半导体厂商在CPU Core的基础上集成了各种各样的外设模块,以适用于不同的应用需求。用户需要关心的就是这款MCU有哪些资源,寄存器如何配置。如果我想根据自己的应用需求来定制一款MCU,但是半导体厂...

() function to improve performance on processors that do not have a hardware Floating Point Unit (e.g. RP2040). Here are two demo images, on the left smooth (anti-aliased) arcs with rounded ends, the image to the right is the same resolution (grabbed from the same 240x240 TFT) with...
An even more accurate solution could be to use a dedicated timer with an input capture unit, that can store the timestamp of a change on the DIO0 pin (the only one that is timing-critical) entirely in hardware. Experience shows that this is not normally required, so we leave this as ...
