Chapter 1. Introduction to Curiosity Low Pin Count (LPC)

The Curiosity Low Pin Count (LPC) Development Board supports Microchip’s 8-, 14- and 20-pin 8-bit PIC® MCUs. Dual-row expansion headers on either side of the socket offer flexibility of connectivity to all pins on the PIC MCUs. Programming/debugging is accomplished through the PICkit™ On-Board (PKOB), eliminating the need for an external programming/debugging tool. This board provides flexibility for experimentation through an application header with a ground (GND) and supply voltage (VSS) connections. It is also a set of indication LEDs, mTouch® button and push button switches, and a variable potentiometer. Additionally, the Curiosity LPC Board integrates a MikroElektronika mikroBUS™ socket, which can accommodate a variety of plug-in Click™ Board modules that can be used for application development.

1.1 CURIOSITY LOW PIN COUNT (LPC) DEVELOPMENT BOARD KIT CONTENTS

The Curiosity Low Pin Count (LPC) Development Board kit contains the following:

• Curiosity Low Pin Count (LPC) Development Board

• Quick Start Guide

• PIC16F18446 MCU

FIGURE 1-2: CURIOSITY LOW PIN COUNT (LPC) DEVELOPMENT BOARD REV 4



Chapter 2. Getting Started

The Curiosity Low Pin Count (LPC) Development Board contains a PICkit On-Board (PKOB) which allows for both low-voltage programming and low-voltage in-circuit debugging for all supported devices. When used with the MPLAB IDE, in-circuit debugging allows the user to run, modify, and troubleshoot their custom software and hardware quickly, without the need for additional debugging tools.

2.1 PROGRAMMING THE CURIOSITY LOW PIN COUNT (LPC) DEVELOPMENT BOARD

Programming the Curiosity LPC Development Board can be accomplished through MPLAB X IDE (version 3.30 or higher for Rev 2 and version 5.20 or higher for Rev 4).

2.1.1 Programming Using MPLAB® X IDE

1. Connect the Curiosity LPC Board to the computer using the on-board micro-USB connector.

2. Open MPLAB X IDE and either create a new project or open an existing one.

3. Click on the Project Properties icon located in the project’s Dashboard window (as seen in Figure 2-1). Alternatively, the Project Properties window can be opened by clicking on File > Project Properties, or by right clicking on the project name in the Projects window and clicking Properties.

Note: The Curiosity LPC Board must be programmed using Low-Voltage Programming (LVP). The LVP bit of the Configuration Word(s) must be set (LVP = ON or ‘1’).


FIGURE 2-1: PROJECT PROPERTIES BUTTON

4. The Project Properties window will open. This window allows for the selection of the programming tool, compiler and PIC MCU. MPLAB X IDE refers to the Curiosity LPC Board as “Starter Kits” in the Hardware Tool selection window, as seen in Figure 2-2.

FIGURE 2-2: SELECTING THE CURIOSITY LPC DEVELOPMENT BOARD

5. In the upper left-hand corner of the Project Properties window, click on Starter Kits (PKOB). The window will now show the configuration options for the PKOB programmer, as shown in Figure 2-3.


FIGURE 2-3: PROGRAM OPTIONS FOR THE PICkit™ ON-BOARD (PKOB)

6. In the Option categories drop-down menu, select Program Options; ensure that the Low Voltage Programming mode is selected for Programming mode entry (Figure 2-4). The Curiosity LPC Board is now ready to be programmed.

FIGURE 2-4: ENSURE LOW-VOLTAGE PROGRAMMING IS ENABLED


7. Once the project is ready to be programmed, simply click on the Make and Program Device button, and MPLAB X IDE will build and compile the code and program the PIC device, as displayed in Figure 2-5.

FIGURE 2-5: DEVICE PROGRAMMING



Chapter 3. Troubleshooting

This chapter discusses common operational issues and methods to resolve them.

3.1 THE MCU WILL NOT PROGRAM USING THE PKOB

The Curiosity LPC Development Board’s PICkit On-Board (PKOB) uses low-voltage programming. Both MPLAB X IDE and MPLAB Xpress set the Low-Voltage Programming (LVP) bit to a ‘1’, allowing low-voltage programming.

1. When using custom firmware, the LVP bit must be set to ‘1’ in the Configuration Word. MPLAB X IDE will not allow programming using the PKOB unless the bit is properly configured.

2. When using a PIC microcontroller (one not included with the Curiosity Development Board) that has already been programmed using high-voltage programming and the LVP bit is cleared (LVP = OFF or ‘0’), the device will not be recognized and cannot be programmed using the PKOB. Reprogramming the device can be achieved by one of the following two methods:

a) Connect a PICkit™ 3 Programmer to the PIC device dual-row expansion headers, ensuring the appropriate ICSP™, GND, and VDD connections are made. Configure MPLAB IDE to use the PICkit 3 as the programmer, and ensure the LVP bit is set to ‘1’ in the Configuration Word. Reprogram the device.

b) Use an unprogrammed (blank) device and ensure the LVP bit is set to ‘1’ in the Configuration Word.

3.2 THE MPLAB PICKIT™ 4 ON-BOARD (PKOB4) DOES NOT PERFORM

Use the Hardware Tool Emergency Boot Firmware Recovery Utility to restore hard-ware tool boot firmware to its factory state. The recovery utility window can be opened by clicking on Debug > Hardware Tool Emergency Boot Firmware Recovery Utility in MPLAB X IDE.The Curiosity LPC Development Board’s PICkit On-Board (PKOB) uses low-voltage programming. Both MPLAB X IDE and MPLAB Xpress sets the Low-Volt-age Programming (LVP) bit to a ‘1’, allowing low-voltage programming.

Appendix B. General Notes

B.1 mikroBUS™ CLICKS

Module 1 is the main click socket, and Module 2 is the secondary socket. Both sockets are fully compatible with a 40-pin PIC device; however, when using 28-pin devices, not all pins are available.

All pins in Module 1 are available for use with the exception of the mikroBUS's Reset (RST) signal, which is tied to pin RD0. PORT D is not available on 28-pin devices. If the RST signal is needed, remove the solder blob jumper associated with the mikroBUS RST connection, and place a jumper wire between the via next to the solder blob jumper and the desired pin connection found in the J8 or J11 dual-row expansion headers (see Figure 1-1).

All pins in Module 2 are available for use with the exception of the mikroBUS's Reset (RST) signal (RD2), SPI Chip Select (CS) signal (RD3), and the PWM (RD1) signal. These signals are routed to the PORT D pins, which are not available on 28-pin PIC devices. If these signals are needed, remove the solder blob jumpers associated with the mikroBUS connection pins, and place jumper wires from the vias located next to the associated solder blob jumpers to the desired pin connections found in the J8 or J11 dual-row expansion headers (see Figure 1-1).

B.2 SOLDER BLOB JUMPER

Solder blob jumpers can be found on each Click module, push-button switch, LED, or potentiometer connection. This allows the user to utilize those pin connections for other applications.
