Board hardware common setting

Power setting:

Connect J19 pin2 and pin3 Connect J12 pin1 and pin2 Connect J13 pin1 and pin2 Connect J15 pin1 and pin2 Connect J16 pin2 and pin3 Connect J17 pin1 and pin2
Onboard OSJTAG debugger setting:

Leave J5 open Leave J6 open Note: J6 is only used(connected) when firmware update for onboard debugger OSJTAG. Connect J11 pin 1-2, 3-4, 5-6, 7-8, to setup onboard debugger OSJTAG. Note: when use external debugger(connected to J10), leave all J11 pins open.

Connect J1-16 to J3-8(VDD) with a 10K resistor. Caution: the 10K resistor must be used in series within J1-16 and J3-8.
Probe the pwm signal using an oscilloscope
- At J3-15
- At J3-13
- At J3-11
- At J3-7
All PWM signals have the same frequency. The J3-13/15 PWM signal is a pair of duty cycle constantly changing complementary signals with a fixed dead time. The J3-11 duty cycle is half of J3-15, and J3-7 duty cycle is half of J3-11.
Connect J1-16 to GND with a 10K resistor. Caution: the 10K resistor must be used in series within J1-16 and GND. Then J3-15/J3-11/J3-7 PWM signals will be disabled.

Connect USB cable between the host PC and the JM60 USB(J8) port on the target board. It setups OSJTAG and COM port in PC device manager.
Open a serial terminal with the following settings:
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
Download the program to the target board with OSJTAG debug configuration.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo. Please be noted that default FCF(flash configuration field) setting makes MCU boot from bootloader. So after reset button press, it will wait 5s(wait in bootloader) to run the application code.

When the example runs successfully, the following message is displayed in the terminal:
