display accelerometer code to LED

system · April 13, 2015, 5:20pm

I have to different code that work separately one that reads that numbers from the accelerometer and the other that displays that code to a 7 segment display 4 digit LED. I wanted to see if some can help me put the two codes together. I am trying to determine the max acceleration and display that on the LED.

any help would be useful!!!!
thanks in advance

the accelerometer code is:
#include <Wire.h> //Wire library enables I2C communication

// Slave Address
#define LSM303_ACC (0x32 >> 1)
//the 1 removes the last bit of the 8 bit address to get the 7 bit main address. The 8th bit is for reading or writing (1 or 0 tells it to read or write respectively)

//Used register addresses (from datasheet)
#define OUT_X_L_A 0x28
#define OUT_X_H_A 0x29
#define OUT_Y_L_A 0x2A
#define OUT_Y_H_A 0x2B
#define OUT_Z_L_A 0x2C
#define OUT_Z_H_A 0x2D

//Reads value from designated register address on the LSM303
byte LSM303_read(byte address) {
byte temp; //blank variable
Wire.beginTransmission(LSM303_ACC); //designates slave (slave starts listening, other slaves keep ignoring)
Wire.write(address); //designate register (every i2c slave has registers (deals with certain register)
Wire.requestFrom(LSM303_ACC, 1); //read from the register! (see what the current value is)
while(!Wire.available()); //do nothing until data is available
temp = Wire.read(); //turn blank variable into data point
Wire.endTransmission();

return temp; //return variable that is now data point
}

//Function writes value to a control register. (One that you write) Out register (only for reading)
//Writes the given value to the given address
void LSM303_write(byte address, byte data) {
Wire.beginTransmission(LSM303_ACC); //designates slave
Wire.write(address); //designates register
Wire.write(data); //gives register that value (write to the register instead reading from it) change what the register is holding
Wire.endTransmission();
}

void setup() {
// put your setup code here, to run once:
Wire.begin();
Serial.begin(9600);
delay(300);
LSM303_write(0x20, 0b10010111); // low power mode, 5.376 kHz, all accel axes on
}

//ConversionFactor according to datasheet
const double SCALE = 2;
const double conversionFactor = double(SCALE / pow(2, 15)) * 9.81;

void loop() {
// put your main code here, to run repeatedly:
// Create a variable for each axis to hold unitless acceleration values
// Get the least significant bit and most significant bit and combine them to get an integer value
// That reflects the acceleration of that axis
int z = (LSM303_read(OUT_X_L_A) << 8) | LSM303_read(OUT_X_H_A); //int turns 16 bit into integer
int y = (LSM303_read(OUT_Y_L_A) << 8) | LSM303_read(OUT_Y_H_A);
int x = (LSM303_read(OUT_Z_L_A) << 8) | LSM303_read(OUT_Z_H_A);
double accelX = (double)xconversionFactor; //double means decimal. Convert unitless values into m/s^2
double accelY = (double)yconversionFactor;
double accelZ = (double)z*conversionFactor;
Serial.print("x:\t"); Serial.print(accelX);
Serial.print("\ty:\t"); Serial.print(accelY);
Serial.print("\tz:\t"); Serial.println(accelZ);
delay(100);
}
and the LED code is
int aPin = 2; //
int bPin = 3; //
int cPin = 4; //
int dPin = 5; //
int ePin = 6; //
int fPin = 7; //

So combine it the usual way:
stuff before setup goes together
stuff in setup() goes together
stuff in loop() goes together
functions stay separate
No code to exist outside of a function (and setup() and loop() are functions)
Clear up any duplicate uses of pins, variable names.
Confirm the end functionality.

Hi Crossroads,

First of all, I'd like to thank you for responding so quickly.

I am his partner in the group project. I tried inputting the code but a few errors came up:

FORCE_CODE_D.ino: In function 'void loop()':
FORCE_CODE_D.ino:85:36: error: expected primary-expression before '|' token
FORCE_CODE_D.ino:85:60: error: expected ')' before ';' token
FORCE_CODE_D.ino:86:36: error: expected primary-expression before '|' token
FORCE_CODE_D.ino:86:60: error: expected ')' before ';' token
FORCE_CODE_D.ino:87:36: error: expected primary-expression before '|' token
FORCE_CODE_D.ino:87:60: error: expected ')' before ';' token
Error compiling.

Now, I looked online to see why this was and this came up:

Because the system memory.h is shadowing your memory.h, causing the #include to succeed without declaring your types. Several possible fixes:

Rename your file -- probably for the best in any case, to reduce potential confusion.
Include your file via a prefix subdirectory (e.g., #include <myproj/memory.h>).
Move your file into the same directory as the source file, allowing the #include precedence rules for filenames wrapped in " to take effect.
Ensure that your C pre-processor include path options place your project header path prior to the system header paths.

I tried renaming the code but that was not the problem.
I don't understand the second point (include your file via a prefix...etcetc)

I wonder what the problem is. Could you help? Thank you so much.

What code? Between the two of you, you REALLY should have read the sticky threads at the top of forum BEFORE posting.
