AN3097 The EVAL6460 controlled by the EVAL_IBU-STR7
Doc ID 16599 Rev 2 15/34
6. nRESET feedback capability
Figure 12. nRESET feedback capability
By closing this jumper the nRESET pin is directly readable by the EVAL_IBU-STR7.
3.1.2 Loads and board supply connection
1. Connect the DC motor to the DC1 (J3) and DC2 (J4) connectors
2. Connect the stepper motor to the DC3 (J5) and DC4 (J6) connectors
3. Connect the regulator loads:
a) 5.1 Ω - 50 W to VSWDRV (J9) connector
b) 1.5 Ω - 10 W to VswMain (J7) connector
c) 3.3 Ω - 1 W to VlinMain (J8) connector
3.1.3 The EVAL6460, EVAL_IBU-STR7 and PC interface
1. Connect EVAL_IBU-STR7 with EVAL6460 via a standard 34-pin ribbon cable interface
2. Connect EVAL_IBU-STR7 to the PC by a serial cable not crossed
3. Connect the EVAL6460 power supply (VSupply - J2)
4. Connect the EVAL_IBU-STR7 power supply (VS - J2): the VS LED turns-on together
with the 3.3 V LED (3.3 V is generated on board). VS must be in the range of 4.4 V to
36 V.
The EVAL_IBU-STR7 supply may also be provided by a USB cable. The 5 V LED turns-on
to display the presence of the USB supply.
3.2 Starting flexSPIN evaluation software
First of all copy the files - executable and COMset - in the same directory. The "com1set.txt"
file indicates by its name the serial port used as follow:
● com1set.txt ==> software uses COM1
● com2set.txt ==> software uses COM2
● com3set.txt ==> software uses COM3
● com4set.txt ==> software uses COM4
Confirm that the power supplies of the EVAL_IBU-STR7 board and the EVAL6460 board are
turned on then double click the "flexSPIN.exe" file.
A window with a drawing of the board appears, see Figure 13.
