Microchip has made available 10 new and existing application-specific PICtail Plus daughter boards for the popular Explorer 16 Development Board platform, which supports Microchip’s 16-bit PIC24 microcontrollers (MCUs) and dsPIC33 digital signal controllers (DSCs), and the 32-bit PIC32 MCUs, through numerous processor-specific plug-in modules. PICtail Plus daughter cards can be used to adapt the board for specific applications, reducing prototype development time while providing additional reference design insight for the final design.
The daughter boards may be used in combination with each other and include the following variants:
* USB board including example circuits for USB implementation, and free USB 2.0 Embedded Host and on-the-go (OTG) stacks.
* Ethernet board, populated with Microchip’s 28-pin ENC28J60 MAC/PHY Ethernet controller, which interfaces to the SPI bus of the microcontroller.
* Motor Control Interface board with hardware support for sensor and sensorless applications, such as Hall sensors, optical encoders, back EMF and current sensing.
* Graphics board demonstrating Microchip’s graphic LCD display solution, including a graphics library for 16- and 32-bit processors. Contains a colour QVGA display with resistive touch screen capability.
* Speech Playback board implementing a fourth-order low pass filter, speaker amplifier, speaker and 1 Mbit SPI serial EEPROM for playback-only applications.
* Audio board featuring microphone or line inputs, plus line output and speaker output, for audio applications.
* Board for SD and MMC cards, a universal board that interfaces secure digital (SD) and multimedia card (MMC) memory cards to the SPI bus of the Explorer 16 processor.
* Prototype board, an expansion breadboard card for the Explorer 16, using any of Microchip’s 16- or 32-bit controllers.
* ECAN/LIN board to facilitate implementation and evaluation of applications that use controller area network (CAN) and local interconnect network (LIN) interfaces that are implemented on selected dsPIC33 DSCs and PIC24H 16-bit MCUs.
* IrDA board, expanding the functionality of the Explorer 16 to include IrDA communications.
Most PICtail Plus daughter boards have a significant software library repository to support their targeted applications. These include communication and file-management stacks and firmware drivers, compression and audio-processing libraries, motorcontrol libraries and graphics libraries, which are available for free download and evaluation.
