TMC7300示例腳本

Trinamic最近推出了一系列新的電池供電的電機(jī)驅(qū)動(dòng)芯片，其中包括TMC7300，TMC7300能夠驅(qū)動(dòng)1個(gè)高達(dá)2A的直流電動(dòng)機(jī)或2個(gè)高達(dá)2.4A（峰值）的直流電動(dòng)機(jī)。在本文中，將向您展示一個(gè)小的示例腳本，使用TMC7300-EVAL-KIT驅(qū)動(dòng)直流電動(dòng)機(jī)。

首先，通過使用Eselsbrücke連接器板將TMC7300-EVAL板與Landungsbrücke接口板連接來組裝評(píng)估套件。其次，將電機(jī)連接到評(píng)估板上。最后，插入U(xiǎn)SB-C電纜連接電腦，以使用TMCL-IDE直接訪問計(jì)算機(jī)。

設(shè)置完成后，可以調(diào)整TMC7300直流驅(qū)動(dòng)器IC，并立即在圖形用戶界面中實(shí)時(shí)查看電動(dòng)機(jī)運(yùn)行狀態(tài)。

使用TMCL-IDE，創(chuàng)建了一個(gè)簡(jiǎn)短的示例腳本，該腳本可移動(dòng)直流電動(dòng)機(jī)，如圖所示。電動(dòng)機(jī)PWM的占空比從0％變?yōu)?0％，再到50％，然后又回到零。之后，它在負(fù)方向上顯示相同的值。

以下是使用的腳本:
