MPU6050 teapot with other microcontrollers

psevekar

greetings !! After successfully running MPU6050 DMP Teapot Demo for Arduino, Now i want to implement the same using other microcontroller ( cypress or PIC or Renesas ). Do i need to include any other libraries for this in processing ? What should be the packet format for data to be sent from other controllers. For arduino we used ...// packet structure for InvenSense teapot demo as- uint8_t teapotPacket[14] = { '$', 0x02, 0,0, 0,0, 0,0, 0,0, 0x00, 0x00, '\r', '\n' }; what does each byte represent in this format ?? Thanks.

I guess uint8_t means unsigned char maybe? :-??

I've just tweaked my previous "Efficient Serial ReadBytes" example from:
https://forum.Processing.org/two/discussion/15278/processing-arduino-flexiforce#Item_3

It's relying on Serial's buffer() & readBytes() methods in order to receive those 14 sent bytes within serialEvent():

2. https://Processing.org/reference/libraries/serial/Serial_readBytes_.html
3. https://Processing.org/reference/libraries/serial/serialEvent_.html

import processing.serial.Serial;

static final int BYTES = 14, PORT_IDX = 3, BAUDS = 9600;
final byte[] receivedBytes = new byte[BYTES];

void setup() {
  noLoop();
  final String[] ports = Serial.list();
  printArray(ports);
  new Serial(this, ports[PORT_IDX], BAUDS).buffer(BYTES);
}

void draw() {
  println(receivedBytes);
}

void serialEvent(final Serial s) {
  s.readBytes(receivedBytes);
  redraw = true;
}

dear gotoloop, Which microcontroller and sensor was used for your application. What consideration should be taken in to account while using processing environment along with other microcontroller and mpu6050. I am willing to model mpu6050's movement to processing using cypress/renesas microcontroller.

I don't have any of those hardware. It's completely a shot in the dark attempt. :-O
