資源簡(jiǎn)介

實(shí)驗(yàn)器材:

戰(zhàn)艦V3\精英STM32F103開(kāi)發(fā)板

實(shí)驗(yàn)?zāi)康?
學(xué)習(xí)ATK-2MD4850 步進(jìn)電機(jī)驅(qū)動(dòng)器的使用，學(xué)會(huì)使用驅(qū)動(dòng)器控制步進(jìn)電機(jī)相對(duì)定位和絕對(duì)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(zhuǎn)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(jìn)電機(jī)驅(qū)動(dòng)器控制信號(hào)線如下
DRIVER_DIR <-------------> PC0 (OV_D0)
DRIVER_OE  <-------------> PC2 (OV_D2)
STEP_PULSE <-------------> PC7 (TIM8_CH2,OV_D7)

實(shí)驗(yàn)現(xiàn)象:
本實(shí)驗(yàn)通過(guò)usmart或者板載按鍵調(diào)用單片機(jī)里面的函數(shù)，實(shí)現(xiàn)對(duì)步進(jìn)電機(jī)驅(qū)動(dòng)器的控制，從而控制步進(jìn)電機(jī)的相對(duì)定位和絕對(duì)定位;
按下KEY0,步進(jìn)電機(jī)以500HZ的頻率順時(shí)針轉(zhuǎn)動(dòng)200個(gè)脈沖的角度(相對(duì)定位);
按下KEY1,步進(jìn)電機(jī)以500HZ的頻率逆時(shí)針轉(zhuǎn)動(dòng)400個(gè)脈沖的角度(相對(duì)定位);
按下KEY_UP,步進(jìn)電機(jī)以500HZ的頻率回到絕對(duì)原點(diǎn)(絕對(duì)定位);
同時(shí)DS1 以1s的周期閃爍，提示代碼正在運(yùn)行。

注意事項(xiàng):
1,串口波特率為115200.
2,請(qǐng)用USB線連接在USB_232,找到USB轉(zhuǎn)串口后測(cè)試本例程.
3,P4(P3精英板)的PA9/PA10必須通過(guò)跳線帽連接在RXD/TXD上. 
4,驅(qū)動(dòng)器接收脈沖頻率范圍 20Hz~100KHz.
5,這個(gè)測(cè)試代碼不支持電機(jī)加減速控制，所以一定注意電機(jī)的啟動(dòng)轉(zhuǎn)速不能設(shè)置過(guò)高(≤180rpm)，否則可能導(dǎo)致電機(jī)堵轉(zhuǎn)!!
6,驅(qū)動(dòng)器控制信號(hào)線占用了OV_D1,OV_D6,OV_D7，所以這個(gè)例程不能使用攝像頭模塊.
