假设经过测试你确定用其中的两个引脚(例如标记为 PIN_A 和 PIN_B)联通时即表示按键被按下。 1.2 典型接法示例 目标:利用 Arduino 内置的上拉电阻,在未按下时输入保持 HIGH,按下时 PIN_A 与 PIN_B 接通后将输入拉 LOW。 电路示意: 将其中一个触点(例如 PIN_A)接到 D1 UNO R3 的数字输入引脚(比如 ...
Connect the V+ terminal on the power supply to the Vmot screw terminal on the grblShield. I used 16 AWG stranded wire. Connect the V- terminal on the power supply to the GND screw terminal on the grblShield. Confirm you have the wires between the power supply and grblShield connected p...
When you download thegbrl-masterand unzip the file, in the folder you will find a folder calledgrbl, inside that folder you find a folder calledcpu_map, inside that folder you will find 2 files,cpu_map_atmega328p.handcpu_map_atmega2560.h. As this shield is for theArduino NANO, the f...
