![]() ![]() The purpose of pin connect block is to configure microcontroller pin to desired function. Initialize a microcontroller system, which take care setup procedure like powering up peripherals, set clock rate etc.Ĭonnect necessary pin using pin connect block. While writing an application to blink LED, we have to follow general steps: Writing zero does not have any effect and hence it can’t be used to drive a pin to Logic 1 This register can be used to drive an ‘output’ configured pin to logic 0 i.e. For driving pins LOW IOxCLR is used which is explained as below: Writing zero does not have any effect and hence it can’t be used to drive a pin to Logic 0 i.e. This register can be used to drive an ‘output’ configured pin to logic 1 i.e. Setting a bit to ‘0’ in this register will configure the corresponding pin to be used as input while setting it to ‘1’ will configure it as output. This is the GPIO direction control register. It gives the current state of GPIO pin when read. Now I have added four states in the circuit, when I make any state one that stator got magnetize and the motor. ![]() Now design the circuit as shown in the below figure: This circuit is just for understanding purposes. First of all, add the below two components from the Proteus library in the workspace. Regardless of the direction set for the particular pins. Stepper Motor Drive Circuit in Proteus ISIS. This register can be used to read or write values directly to the pins. Lpc2148-keil-LED-BLINKING-using-keilv4-proteus. ![]()
