MPLAB® STARTER KIT FOR INTELLIGENT.INTEGRATED.ANALOG USER’S GUIDE Chapter 1. Introduction to the Starter Kit Thank you for purchasing the MPLAB Starter Kit for Intelligent.Integrated.Analog. This board is intended to introduce the PIC24FJ128GC010 family of advanced analog microcontrollers and demonstrate its wide range of on-chip analog features. This chapter introduces the Starter Kit and provides an overview of its features. Topics covered include: • • • • 1.
MPLAB® Starter Kit for Intelligent.Integrated.Analog User’s Guide 1.2 WHAT’S IN THE KIT Your MPLAB Starter Kit for Intelligent.Integrated.Analog should contain the following: • MPLAB Starter Kit board • USB cable (A to mini-B) • An insert card with links to the web site for this manual and the demo application 1.3 HARDWARE Figure 1-1 identifies the major features of the Starter Kit.
Introduction to the Starter Kit 1. PICkit On Board (PKOB) USB Programmer/Debugger and Connector The PKOB is used to program the PIC24FJ128GC010 MCU on the Starter Kit. It connects via USB to MPLAB X, Microchip’s programming and debugging environment, and eliminates the need for an external hardware programmer. For more information on loading your own application into the Starter Kit (or reloading the original application), see Section 3.1 “Reprogramming the Starter Kit Using the PKOB”. 2.
MPLAB® Starter Kit for Intelligent.Integrated.Analog User’s Guide 9. Digital Temperature Sensor (U9) and Jumper, JP7 The TC77 is a digital temperature sensor in a SOT-23 package. It uses an SPI interface to communicate to the microcontroller. The TC77 is powered as part of the SWITCHED_VDD bus. When installed (default), jumper, JP7, connects the TC77 chip select to port pin, RE9. If the TC77 is not needed, removing JP7 allows port pin, RE9, to be used as a general purpose I/O resource. 10.
Introduction to the Starter Kit 14. Breakout Connectors (J7/J8) Connectors, J7 and J8, provide a direct interface to select functions of the PIC24FJ128GC010 microcontroller. Connector, J7, is a standard riser and can accept standard 0.025” square posts. J8 is a parallel connected set of through holes. The mapping of microcontroller pins to riser pins is listed in Table 1-1. Many of the microcontroller pins are multiplexed with several functions. Refer to Appendix A.
MPLAB® Starter Kit for Intelligent.Integrated.Analog User’s Guide 1.3.1 Power Sources The Starter Kit can be powered in one of three ways, depending on the usage: • PKOB USB Connector (J6). This will power the entire MPLAB Starter Kit board, including the PICkit programming circuitry. Jumper, J10, must be placed into the USB position (Pins 2-3), which is the default position. Both power LEDs (D4 and D5) will light. • USB Device Port (J3).
MPLAB® STARTER KIT FOR INTELLIGENT.INTEGRATED.ANALOG USER’S GUIDE Chapter 2. The Demonstration Application This chapter describes the preprogrammed demonstration on the Starter Kit. The application is essentially free-standing and does not require a host application running on a computer. The board can be powered from either USB mini-B connector (J3 or J6). 2.1 START-UP DISPLAY The application displays a 24-hour clock (hh:mm, with flashing colon).
MPLAB® Starter Kit for Intelligent.Integrated.Analog User’s Guide 2.2.1 Clock Demo The 24-hour clock is the home page for the demo. This is a 24-hour clock with a blinking colon for seconds. The clock uses the on-board 32 kHz Secondary Oscillator (SOSC) for an accurate time base. To set the clock to the proper time: 1. Press when the LCD is displaying the clock. 2. The display shows, hh:mm, where ‘hh’ is the current hour and ‘mm’ is the current minute.
The Demonstration Application 2.2.3 Pipeline A/D Demo This section of the demo uses the 12-bit Pipeline A/D Converter. For more information on this module and its operation, refer to the “PIC24F Family Reference Manual”, “12-Bit, High-Speed Pipeline A/D Converter” (DS30686). The Pipeline A/D demo uses two analog input channels of the Pipeline A/D Converter to display a pair of bar graphs. The bar graphs extend, left-to-right, across the LCD.
MPLAB® Starter Kit for Intelligent.Integrated.Analog User’s Guide 2.2.7 Audio/Microphone Demo This section uses a bar graph display to represent the output of the unamplified electret microphone. The 12-bit Pipeline A/D Converter is used to measure the amplitude of the output signal. To use this section, it is necessary to first connect MIC OUT (J7/J8, Pin 5) to ADC1 IN (Pin 11) with a jumper wire (22 gauge recommended).
The Demonstration Application 2.3 OTHER HARDWARE RESOURCES ON THE STARTER KIT Connector, J2, is configured as a USB host. As it is connected in parallel with the USB device port connector, J2 cannot be used while J3 is in use. A footprint (R5) is provided on the board for an add-on thermistor. The footprint is designed to accommodate an NTC thermistor in an 0805 package size. Typical values are 10 kΩ and 47 kΩ.

MPLAB® STARTER KIT FOR INTELLIGENT.INTEGRATED.ANALOG USER’S GUIDE Chapter 3. Developing New Applications The MPLAB Starter Kit for Intelligent.Integrated.Analog may be used with MPLAB® IDE, the free Integrated Development Environment available on Microchip’s web site. MPLAB IDE allows the starter kit to be used as an in-circuit debugger as well as a programmer for the featured device.
MPLAB® Starter Kit for Intelligent.Integrated.Analog User’s Guide MPLAB X refers to it as “Starter Kits (PKOB)”; see Figure 3-2. In the MPLAB X example, the Serial Number (SN) of the board will differ from the one shown. In all cases, be sure to select PIC24FJ128GC010 as the device name in the Project window. FIGURE 3-2: SELECTING THE PKOB The application originally included with the Starter Kit is not protected; you may overwrite it with your own code.
Developing New Applications 3.2 HARDWARE CONSIDERATIONS FOR NEW APPLICATIONS When developing your own application for the Starter Kit board, it is important to set each pin on the microcontroller’s I/O ports to the proper type (analog or digital) and to the proper state (input or output). Certain I/O pins on the PIC24FJ128GC010 microcontroller (and the corresponding pin on J7/J8) can be used as general purpose I/Os.

MPLAB® STARTER KIT FOR INTELLIGENT.INTEGRATED.ANALOG USER’S GUIDE Chapter 4. Troubleshooting This chapter discusses common operational issues and how to resolve them. 1. The demo application does not run. The Starter Kit board must be plugged into a powered USB hub, computer or other USB host device. Start by plugging into the USB device port, J2. LED, D4, should light when VBUS is detected. If D4 is not lit, verify that the USB host side port is functional.
