    +

    下面要注意 :

    +
      +
    1. 在docker裡面 make
      2. +
    2. LINUX_DIR 要擺已經Build過的 kernel 位置
      3. +
    3. aarch64 tool chain 要有 : source /usr/local/oecore-x86_64/environment-setup-aarch64-poky-linux
      4. +
    +
    PWD := $(shell pwd)
+

    GPIO PWM執行輸出與佔空比設定

    +

    Export PWM

    +
    echo 0 > /sys/class/pwm/pwmchip32/export
+

    PWM 週期設定,單位為ns, gpioi12 輸出頻率為 100 HZ

    +
    echo 10000000 > /sys/class/pwm/pwmchip32/pwm0/period
+

    PWM 佔空比設定, 以下設定佔空比為 0.5

    +
    echo 5000000 > /sys/class/pwm/pwmchip32/pwm0/duty_cycle
+

    PWM 使能輸出

    +
    echo 1 >/sys/class/pwm/pwmchip32/pwm0/enable
+
    echo 0 會 export ，這個時候，會出現pwm0的節點
    +
    echo 0 > /sys/class/pwm/pwmchip32/export
+echo 20000000 > /sys/class/pwm/pwmchip32/pwm0/period
+echo 1000000 > /sys/class/pwm/pwmchip32/pwm0/duty_cycle
+echo 2000000 > /sys/class/pwm/pwmchip32/pwm0/duty_cycle
+echo 1 >/sys/class/pwm/pwmchip32/pwm0/enable
+
    PWM1 也是差不多的方式
    +

    echo 1 export ，這個時候會出現pwm1的節點

    +
    echo 1 > /sys/class/pwm/pwmchip32/export
+echo 20000000 > /sys/class/pwm/pwmchip32/pwm1/period
+echo 1000000 > /sys/class/pwm/pwmchip32/pwm1/duty_cycle
+echo 2000000 > /sys/class/pwm/pwmchip32/pwm1/duty_cycle
+echo 1 >/sys/class/pwm/pwmchip32/pwm1/enable
+

    SG90 伺服馬達說明

    +

    小巧輕便且輸出功率高。伺服馬達可以大約旋轉180度（每個方向90度），並且與標準的伺服馬達一樣工作，只是體積更小。

    +

    您可以使用任何伺服馬達的程式碼、硬體或庫來控制這些伺服馬達。

    +

    對於初學者來說非常適合，他們想要讓東西移動，而不需要建立帶有反饋和齒輪箱的馬達控制器，尤其是因為它可以放在狹小的空間中。

    +

    位置 “0”（1.5 毫秒脈衝）代表中間位置。

    +

    位置 “90”（約 2 毫秒脈衝）代表向右極限。

    +

    位置 “-90”（約 1 毫秒脈衝）代表向左極限。

    +

    簡單來說，這段描述了 PWM 信號的位置與對應的角度之間的關係。位置 “0” 代表中間位置，位置 “90” 代表完全向右轉的極限，而位置 “-90” 則代表完全向左轉的極限。這些位置對應於 PWM 脈衝的持續時間，可以控制舵機或其他類似裝置的運動位置。

    注意

    +

    100 Hz 是 :

    +

    echo 10000000 > /sys/class/pwm/pwmchip32/pwm0/period

    +

    Datashet 要 50 Hz

    +

    要寫成以下才會是50 Hz:

    +
    echo 20000000 > /sys/class/pwm/pwmchip32/pwm0/period
    +

    1 ms 的duty 我要給以下:

    +

    echo 1000000 > /sys/class/pwm/pwmchip32/pwm0/duty_cycle

    +

    1.5 ms 的duty 我要給以下:

    +

    echo 1500000 > /sys/class/pwm/pwmchip32/pwm0/duty_cycle

    +

    2 ms 的duty 我要給以下:

    +

    echo 2000000 > /sys/class/pwm/pwmchip32/pwm0/duty_cycle

代表中間位置，位置 \u0026ldquo;90\u0026rdquo; 代表完全向右轉的極限，而位置 \u0026ldquo;-90\u0026rdquo; 則代表完全向左轉的極限。這些位置對應於 PWM 脈衝的持續時間，可以控制舵機或其他類似裝置的運動位置。\n注意 100 Hz 是 :\necho 10000000 \u0026gt; /sys/class/pwm/pwmchip32/pwm0/period\nDatashet 要 50 Hz\n要寫成以下才會是50 Hz:\necho 20000000 \u0026gt;
