本帖最後由 hon829 於 2019-1-5 11:41 編輯
參考了網上開源項目,用ATiny85模擬keyboard送出Photoshop的shortcut key:
https://www.indiegogo.com/projec ... n-workflow-design#/
Signals Type:
Knob: "[" , "]" //編碼開關轉左或右分別送出中括號
Switch: "b", "e" //按鍵(用編碼開關按鈕代替),分別送出代表選取Brush或Eraser tools的"b"及"e"
用Digispark組裝樣子:
有了概念亦用慣Arduino IDE,故沒跟作者電路及程序,自己很簡單的編寫如下:
#include "DigiKeyboard.h"
#include <avr/wdt.h>
#define encoder0PinA 0 //Interrupt input
#define encoder0PinB 2 //regular input
#define encoder0Btn 1 //button input, 1 = has not been pressed
//pin 2, USB+ PB3
//pin 3, USB- PB4
int valRotary = 0;
bool Toggle_button = 0;
void doEncoder() { //Interrupt Service Routine
if (digitalRead(encoder0PinA) == digitalRead(encoder0PinB)){ //two input same, CW
valRotary=2;}
else{ valRotary=1; }
}
void setup() {
pinMode(encoder0PinA, INPUT_PULLUP);
pinMode(encoder0PinB, INPUT_PULLUP);
pinMode(encoder0Btn, INPUT_PULLUP);
watchdogSetup(1); //watchdog setup on, for 1 second
attachInterrupt(0, doEncoder, CHANGE); //attachInterrupt(digitalPinToInterrupt(pin), ISR, mode); UNO pin 2(int.0)/3(int.1)
}
void loop() {
DigiKeyboard.update();
if( digitalRead(encoder0Btn) == LOW ){
if( Toggle_button ==0 ){
DigiKeyboard.sendKeyStroke(KEY_E); //KEY_E, 0x08 // e
Toggle_button =1;}
else{
DigiKeyboard.sendKeyStroke(KEY_B); //KEY_B, 0x05 // b
Toggle_button =0;}
DigiKeyboard.delay(300);} //It's better to use DigiKeyboard.delay() over the regular Arduino delay()
if(valRotary == 2){ //CW
DigiKeyboard.sendKeyStroke(KEY_R_BRACKET); //0x30 "]"
DigiKeyboard.delay(100);
valRotary=0;}
if(valRotary == 1) { //CCW
DigiKeyboard.sendKeyStroke(KEY_L_BRACKET); //0x2F "["
DigiKeyboard.delay(100);
valRotary=0;}
wdt_reset(); //periodically reset the watchdog timer
}
void watchdogSetup(boolean on_off){
cli(); // disable all interrupts
wdt_reset(); // reset the WDT timer
WDTCR |= (1<<WDCE) | (0<<WDE); // Enter Watchdog Configuration mode:
WDTCR = (on_off<<WDIE) | (1<<WDE) | (0<<WDP3) | (1<<WDP2) | (1<<WDP1) | (0<<WDP0); // Set Watchdog settings:
sei();
/*
WDTCSR configuration:
WDIE = 1: Interrupt Enable
WDE = 1 :Reset Enable
WDP3 WDP2 WDP1 WDP0 Number of WDT Oscillator Cycles Typical Time-out at VCC = 5.0V
0 0 0 0 2K (2048) cycles 16 ms
0 0 0 1 4K (4096) cycles 32 ms
0 0 1 0 8K (8192) cycles 64 ms
0 0 1 1 16K (16384) cycles 0.125 s
0 1 0 0 32K (32764) cycles 0.25 s
0 1 0 1 64K (65536) cycles 0.5 s
0 1 1 0 128K (131072) cycles 1.0 s
0 1 1 1 256K (262144) cycles 2.0 s
1 0 0 0 512K (524288) cycles 4.0 s
1 0 0 1 1024K (1048576) cycles 8.0 s
*/
}
是可以如設計般操作的,唯間歇性的Windows不能辨識裝置.
為以防程序hang故加了watchDog作reset部份,讓它呆一陣!暫不知程序那部份出了問題?
(或許是USB lib.出事 但看不懂!)

你說特意加了 WDT, 那沒有 WDT 是不是就沒有問題?

應該唔關接觸不良或電流量問題.

以為clock的頻率不準,試了cal. OSCCAL值,都沒改善!
以為Digispark個boot loader影響, 剷走都沒改善!

感覺應該是操作到某程序program hang了,要reset隻ATiny85就冇事!

你在Loop 及 interrupt 都調用了digitalRead(), 有沒有確認過這function 是否reentrant 的?
此外, valRotary 這變數是16-bit 的, ATtiny 是8-bit MCU, 在 Loop 裡面 valRotary 當有interrupt 來時也不保證可以 atomic Read or Write, 而 interrupt 裡面也會修改 valRotary, 即使不Hang 機, 也是不safe 或會出錯的.

明白了
以為用中斷可增加對編碼開關的反應,但反而影響了USB的通訊,在轉動太頻密時使USB傻了!
#include "DigiKeyboard.h"
#define encoder0PinA 0 //Interrupt input
#define encoder0PinB 2 //regular input
#define encoder0Btn 1 //button input, 1 = has not been pressed
//pin 2, USB+ PB3
//pin 3, USB- PB4
bool Toggle_button = 0;
int encoder0PinALast = LOW;
int n = LOW;
void setup() {
pinMode(encoder0PinA, INPUT_PULLUP);
pinMode(encoder0PinB, INPUT_PULLUP);
pinMode(encoder0Btn, INPUT_PULLUP);
}
void loop() {
DigiKeyboard.update();
if( digitalRead(encoder0Btn) == LOW ){
if( Toggle_button ==0 ){
DigiKeyboard.sendKeyStroke(KEY_E); //KEY_E, 0x08 // e
Toggle_button =1;}
else{
DigiKeyboard.sendKeyStroke(KEY_B); //KEY_B, 0x05 // b
Toggle_button =0;}
DigiKeyboard.delay(200);} //It's better to use DigiKeyboard.delay() over the regular Arduino delay()
n = digitalRead(encoder0PinA);
if ((encoder0PinALast == LOW) && (n == HIGH)) {
if (digitalRead(encoder0PinB) == LOW) { //two input same, CW
DigiKeyboard.sendKeyStroke(KEY_R_BRACKET); //0x30 "]"
DigiKeyboard.delay(50);}
else { //CCW
DigiKeyboard.sendKeyStroke(KEY_L_BRACKET); //0x2F "["
DigiKeyboard.delay(50);}
}
encoder0PinALast = n;
}
程序改回用polling後,一切都很暢順了

我成日都想自己整啲shortcut key係公司用, 因為公司有IT管, 所以用唔到Admin裝野, 有師兄喱嗰方法, 有時間試下先
