ESP32-S3: SPI w/ Motion Sensor Help

ducvietnguyen2002 · February 16, 2024, 4:51am

Hi everyone, I am new to ESP32 and ESPIDF overall. I am trying to create a project using a ESP32-S3 with a Motion Sensor(PMW3389) to act as a mouse. Despite the project compiling, I couldn’t get the sensor to work and display the correct srom_id reading after downloading the SROM hex file. Any help is appreciated as I feel like I am losing my mind and don’t where to go from here. Thank you in advance for your time!

Link to the project:

Guide I am following:

github.com

mrjohnk/PMW3389DM/blob/master/Arduino Examples/PMW3389DM-polling/PMW3389DM-polling.ino

/*
 * This example bypasses the hardware motion interrupt pin
 * and polls the motion data registers at a fixed interval
 */

#include <SPI.h>
#include <avr/pgmspace.h>

// Registers
#define Product_ID  0x00
#define Revision_ID 0x01
#define Motion  0x02
#define Delta_X_L 0x03
#define Delta_X_H 0x04
#define Delta_Y_L 0x05
#define Delta_Y_H 0x06
#define SQUAL 0x07
#define Raw_Data_Sum  0x08
#define Maximum_Raw_data  0x09
#define Minimum_Raw_data  0x0A

Well if that project doesn’t work, try an Arduino library + sketch instead: https://github.com/dkao/Kensington_Expert_Mouse_PMW3389_Arduino
