Curiosity PIC32MX470 Development Board
pic32mx470_curiosity.jpg

The Curiosity PIC32MX470 Development Board uses the PIC32MX470512H MCU with a 120 MHz CPU, 512 KB flash, 128 KB RAM, full-speed USB and multiple expansion options. It is an excellent development board for Audio, USB and Bluetooth® applications. It has two MikroBus® expansion sockets from MicroElektronika and a connector to mount an audio codec daughter board.

This board has an on-board programmer/debugger. No external programmer/debugger (e.g., ICD4) is required.

The WiFi 7 click board from MikroElectronika uses the ATWINC1510-MR210PB IEEE 802.11 b/g/n module, specifically optimized for low-power IoT applications. It is designed to run on a 3.3 V power supply. It communicates with the target microcontroller over SPI interface, with additional functionality provided by the following pins on the mikroBUS line: PWM, INT, RST.

Harmony example projects

Detailed documentation on select projects can be found on the development board support page. All example projects included in the MPLAB® Harmony software framework are documented in the Harmony Help file under "Volume I: Applications Help". To find all projects that use this specific board, search the Harmony Help file for pic32mx470_curiosity. This is the name of the board support package (BSP) assigned to this development board.

The following projects are included in Harmony version 2.05.01:

Project Name Location Description
Audio Demonstrations
sdcard_player.X <install-dir>/apps/audio/
sdcard_player/firmware
The demonstration application creates an audio player that reads audio files (.WAV format only) from an SD card mounted on the click interface. The audio is played through the CODEC placed on the X32 header interface. It also provides the feature to switch to the next track on the media.
audio_tone.X <install-dir>/apps/audio/
audio_tone/firmware
In this demonstration application, depending on the configuration, the Codec Driver sets up the AK4384 DAC, AK4953 Codec, or AK4954 Codec. The demonstration sends out generated audio waveforms (sine tone and chirp) with parameters modifiable through on-board push buttons. Success is indicated by an audible output corresponding to displayed parameters.
USB
cdc_com_port_dual.X <install-dir>/apps/usb/
device/cdc_com_port_dual/
firmware
This demonstration application creates a USB CDC Device that enumerates as two serial ports on the USB Host personal computer. This application demonstrates the ability of the MPLAB Harmony USB Device Stack to support multiple instances of the same Device class.
msd_basic.X <install-dir>/apps/usb/
host/msd_basic/firmware
This application demonstrates the use of the MSD Host Class Driver to write a file to a USB Flash drive. The application uses the USB Host_layer , MSD class driver and the MPLAB Harmony File System Framework to enumerate a USB Flash drive and to write a file to it.
msd_multiple_luns.X <install-dir>/apps/usb/
device/msd_multiple_luns/
firmware
This application demonstrates the creation of a USB device with multiple logical units. The storage media, SD Card, acts as one logical unit, and the NVM acts as the second logical unit. Data transfer between a computer and the logical units (SD Card / NVM) takes place through USB MSD.
