dspic33ck curiosity sent loopback demo

Summary

The project depicts the usage of SENT module demo with loopback data transfer from two SENT peripherals, where one acts as a transmitter and other as receiver on dsPIC33CK Curiosity Board using MPLAB® Code Configurator.

Setup

Hardware Setup

• Connect a micro-USB cable to port J7 of Curiosity board to USB port of PC
• Connect a jumper wire from SENT_Tx (RD0) - SENT_Rx (RD1)

MPLAB® X IDE Setup

• Open the dspic33ck-curiosity-sent-loopback-demo.X project in MPLAB® X IDE
• Build and program the device

Serial Port Setup

Operation

• The demo auto triggers two operation modes of SENT - Asynchronous and Synchronous, once the device is programmed.
• The very first state is the Initialization state where the user configurable SENT Payload details are being initialized. User can edit the data inside the function if required.
• In Asynchronous mode operation where the SENT_TX sends the data and SENT_RX peripheral receives the same data. On success the result will be printed on terminal and green LED starts glowing.
• Succeeding the state is the Synchronous mode of operation, which also sends the data from SENT_Transmitter and receives in SENT_Receiver. On success, the result will be printed on terminal and green LED starts glowing.
• Finally the SENT peripherals are reset to POR (Power On Reset) state at the deinitialization.
• Note that printf() is redirected to UART1 by the compiler for this device
