資源簡介
實驗器材:
戰艦V3\精英STM32F103開發板實驗目的:
學習ATK-2MD4850 步進電機驅動器的使用，學會使用驅動器控制步進電機相對定位和絕對定位。
硬件資源:
1,DS0(連接在PF9).
2,串口1(波特率:115200,PA9/PA10連接在板載USB轉串口芯片CH340上面).
3,按鍵KEY0(PE4)/KEY1(PE3)/KEY_UP(PA0,也稱之為WK_UP) .
4,步進電機驅動器控制信號線如下
DRIVER_DIR <-------------> PC0 (OV_D0)
DRIVER_OE <-------------> PC2 (OV_D2)
STEP_PULSE <-------------> PC7 (TIM8_CH2,OV_D7)
實驗現象:
本實驗通過usmart或者板載按鍵調用單片機里面的函數，實現對步進電機驅動器的控制，從而控制步進電機的相對定位和絕對定位;
按下KEY0,步進電機以500HZ的頻率順時針轉動200個脈沖的角度(相對定位);
按下KEY1,步進電機以500HZ的頻率逆時針轉動400個脈沖的角度(相對定位);
按下KEY_UP,步進電機以500HZ的頻率回到絕對原點(絕對定位);
同時DS1 以1s的周期閃爍，提示代碼正在運行。
注意事項:
1,串口波特率為115200.
2,請用USB線連接在USB_232,找到USB轉串口后測試本例程.
3,P4(P3精英板)的PA9/PA10必須通過跳線帽連接在RXD/TXD上.
4,驅動器接收脈沖頻率范圍 20Hz~100KHz.
5,這個測試代碼不支持電機加減速控制，所以一定注意電機的啟動轉速不能設置過高(≤180rpm)，否則可能導致電機堵轉!!
6,驅動器控制信號線占用了OV_D1,OV_D6,OV_D7，所以這個例程不能使用攝像頭模塊.
