+# Curiosity HPC Labs Using PIC18F47Q10
 
-# INTRODUCTION
+## Introduction
 
-The following labs in this demo code project are designed for Microchip’s Curiosity High Pin Count (HPC) Development board. This development board supports Microchip's 28 and 40-pin 8-bit PIC® MCUs. This MPLAB X project contains several lab exercises that demonstrate a large number of basic capabilities of PIC® devices and can also be used to test the condition of the board. Each lab contains a brief description of the lab and discussions to make you become easily acquainted with the different peripherals and registers of PIC® MCUs. These labs also make use of the MPLAB Code Configurator (MCC), an easy-to-use plugin tool for MPLAB X IDE. MCC can be used to setup the peripherals and also generates drivers which can be used in the application code. All labs are written in C language and are compatible with the latest XC8 compilers.

 #### Summary
-The LEDs are connected to the Input/Output (I/O) pins. First, the I/O pin must be configured as output. In this case, when one of these pins is driven high (LED_D2 = 1), the LED will turn on. These two logic levels are derived from the power pins of the PIC MCU. Since the PIC's power pin (V<sub>DD</sub>) is connected to 5V or 3.3V and the source (V<sub>SS</sub>) to ground (0V), a logic level of '`1`' is equivalent to 5V or 3.3V, and a logic level of '`0`' is 0V.

 #### Summary
-The PIC18-Q10 family of devices have an on-board Analog-to-Digital Converter with Computation (ADCC) with 10 bits of resolution. The converter can be referenced to the device's V<sub>DD</sub> or an external voltage reference. This lab references it to V<sub>DD</sub>. The result from the ADC is represented by a ratio of the voltage to the reference.

 This lab combines all previous ones to produce a variable speed rotating LED display that is proportional to the ADC value. The ADC value and LED rotate speed are inversely proportional to each other.

 ### <u>Lab 8: Interrupts</u>
 #### Introduction
-This lab discusses all about interrupts—their purpose, capabilities and how to set them up. Most interrupts are sourced from MCU peripheral modules. Some I/O pins can also be configured to generate interrupts whenever a change in state is detected. Interrupts usually signal events that require servicing by the software's Interrupt Service Routine (ISR). Once an interrupt occurs, the program counter immediately jumps to the ISR to clear the interrupt flag, and then resumes what it was doing before. It is a more efficient way of handling events than continuously polling a status flag.

 #### Hardware Effects
-Once this lab is in Running state, the WDT will start counting. While in Sleep mode, LEDs D2/D4 and D3/D5 are turned ON and OFF, respectively. Pressing the switch won't go to the next lab since the PIC is in Sleep mode. After the WDT has reached its period, which is approximately 4s for this lab, the PIC exits Sleep mode and the four LEDs, D2 through D5, are toggled.
