ICP DAS USA 3-axis encoder card, 2-axis stepping/servo, I-8091 2-axis stepping/servo Icpdas

I-8090 User Manual Version 1.0 06/2001

address: hardware address which defined at chapter 1.1

Return: “YES” : registration successful “NO” : registration failure.

Example: This example will assign I-8090 card address=0x080 as CARD1 (1). Then initial the I-8090 card and reset X,Y,Z axis encoder counter value to 0.

#define CARD1 1

…

i8090_REGISTRATION(CARD1, 0x080);

i8090_INIT_CARD(CARD1, ENC_QUADRANT, ENC_QUADRANT, ENC_QUADRANT);

i8090_RESET_ENCODER(CARD1, X_axis);

i8090_RESET_ENCODER(CARD1, Y_axis);

i8090_RESET_ENCODER(CARD1, Z_axis);

(2)void i8090_INIT_CARD(unsigned char cardNo, unsigned char x_mode, unsigned char y_mode, unsigned char z_mode)

This command will reset all three axis’s counter value of “cardNo” card, and assign its counting mode. The counting mode (S1,S0) has been explained in registers XCTRL, YCTRL, ZCTRL.

cardNo: 0~19, select which card.

x_mode, y_mode, z_mode: select the counting mode. 0x00 : quadrant counting mode

0x10 : CW/CCW counting mode

0x20 : Pulse/Direction counting mode

Example:

#define ENC_QUADRANT 0x00

#define ENC_CW_CCW 0x10 #define ENC_PULSE_DIR 0x20
