 So now, what we need to validate before we first turn on our application. So before we switch the application on for the first time, please check the proper setup of the jumpers and soldering switches to choose the proper current reading topology, whether it's single or three shunt. Please check the speed sensor configuration, the order of the signals from the whole sensor, from the encoders, the proper supply for the encoder and the whole sensors, if possible, because there may be options for 5 and 3.3 volts, and the setup of the overcurrent and over temperature mechanisms. Further, we need to check the polarity and rating of the supply voltage and the setup and range of the DC-DC converters, if they are present on the board. Of course, it's usually to be sure that we use some isolation for mains supplies, for application and also for scope, and if you use some power supply, it's good to use current limitation to be sure that something is not wrong on your PCB. And if you have a DAC output, it's good to have a connection to oscilloscope. Okay, so when we turn on our application for the first time, we shall first check the supply current. If the motor doesn't spin, the current consumption shall be only a few tens of milliamps, and if the current is too high, it's beneficial if your current limitation on the power supply cuts the voltage down, and only if the supply is in the reasonable range, we can continue further. Second part, it's connect your application to PC through the USART communication and detect if your application running well. Okay, then when you command the application to start your motor, please check that the overcurrent is not reported either by the protection circuitry of your board or of the power supply. Then it's good to check DAC output if you see a good sinusoidal signal in current.
