pinout
Image 2 - Arduino UNO family (pinouts and PINOUT) - NOB's Arduino Diary! - Yahoo! Blog
Arduino Uno, Mega, Micro, etc. are listed in an easy-to-understand manner.
It's the easiest to see that I've ever looked into.
Setting for high-speed PWM
How to use Timer and PWM in AVR | Ushiko log
The book contains detailed and easy-to-understand instructions on how to set a fast PWM setting and how to set clock division.
sample
void setup() { pinMode(9,OUTPUT); pinMode(10,OUTPUT); //TCCR1A = 0b10000010; //10:コンペアマッチAでLOW,10:高速PWM動作 TCCR1A = 0b10100010; //10:コンペアマッチAでLOW,10:高速PWM動作 //制御レジスタB TCCR1B = 0b00011001; //11:高速PWM動作, 001:分周なし //最大値 ICR1 = 649; //0から数える. 全体時間 65ms //0.000001 * 65000 : 65ms //HIGHの時間(クロック数) OCR1A = 324; //0から数える. High時間 32.5ms //0.000001 * 32500 : 32.5ms //OCR1AはPB1ピン OCR1B = 324; } void loop(){ }
