The program then executes in a loop continuously and increments a Of the program PORT B pins are configured as outputs, and bit 1 of PORT C (RC1) isĬonfigured as input. The operation of the project is described in the PDL given in Figure 7.6. Switch RC1 so that its output goes from logic 1 to 0 when the switch is pressed:ĭIP switch SW12 position PORTB, set to ON The following jumpers should beĬonfigured on the board to enable PORT B LEDs, and also to configure the push-button In this project the LV-32MX V6 development board is used. The microcontroller is operated from 8 MHzĬrystal connected between its crystal oscillator pins. A push-button switch is connected toīit 1 of PORT C (RC1) using a pull-up resistor. Of a dice are connected to PORT B of a PIC32MX460F512L microcontroller in currentsourcing mode using 120 U current-limiting resistors. The circuit diagram of the project is shown in Figure 7.5. Which gives the same resistor value of 120 U. In practice, the output voltage is about 3.3 V and the value of the resistor can be In this mode, the LED is turned ON when the microcontroller output port is at logic 1, i.e. The microcontroller output port and the cathode leg is connected to the ground through a Substituting the values into the equation, we get R ¼ 3:3'Īs shown in Figure 7.4, in current-sourcing mode, the anode leg of the LED is connected to ILED is the current through the LED (10 mA). VLED is the voltage drop across the LED (2 V) We can calculate the value of the required resistor as follows: The LED is turned ON when the output of the microcontroller is at logic 0, so that currentįlows through the LED. The current through the LED and this current can vary between 8 and 16 mA, with a typical The voltage drop across an LED is around 2 V. Vdd supply, and the cathode leg is connected to the microcontroller output port through a After 3 s, the LEDs turn OFF again.Īn LED can be connected to a microcontroller output port in two different modes:Ĭurrent-sinking mode and current-sourcing mode.Īs shown in Figure 7.3, in current-sinking mode, the anode leg of the LED is connected to the Pressing the switch generates a random dice number between 1 and 6 and displays on the LEDs are all OFF to indicate that the system is ready to generate a new number. Operation of the project is as follows: normally, the The block diagram of the project is shown in Figure 7.1.Īs shown in Figure 7.2, the LEDs are organized such that when they turn ON, they Integrated development enviornment (IDE) and then selecting (the following are the default This is done by clicking Project / Edit Project in the drop-down menu of the Of 80 MHz b configuring the built-in clock phase locked loop (PLL) module and the clockĬircuitry. Notice that in all of the projects in thisīook although the crystal frequency is 8 MHz, the microcontroller is operated at a clock rate Microcontroller operating with 8 MHz crystal. This is a simple dice project based on LEDs, a push-button switch, and a PIC32MX460F512L In this book, we will be using the PDL for all the projects. The following are provided for each project:Īlgorithm description (in program description language (PDL)) It is recommended that the reader moves through the projects in their We will start with very simple projects and proceed to A breadboard is used where necessary to include any additionalĬomponents required for the projects. Popular LV-32MX V6 development board (with an on-board PIC32MX460F512L 32-bit Most of the hardware for the projects is designed around the We will look at theĭesign of projects using light-emitting diodes (LEDs), push-button switches, keyboards, LEDĪrrays, sound devices and so on, and we will develop programs in C language using the
