i have different code work separately 1 reads numbers accelerometer , other displays code 7 segment display 4 digit led. wanted see if can me put 2 codes together. trying determine max acceleration , display on led.
any 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 last bit of 8 bit address 7 bit main address. 8th bit reading or writing (1 or 0 tells 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 designated register address on 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 register)
wire.requestfrom(lsm303_acc, 1); //read register! (see current value is)
while(!wire.available()); //do nothing until data available
temp = wire.read(); //turn blank variable data point
wire.endtransmission();
return temp; //return variable data point
}
//function writes value control register. (one write) out register (only reading)
//writes given value 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 value (write register instead reading it) change register holding
wire.endtransmission();
}

}
//conversionfactor according datasheet

const double conversionfactor = double(scale / pow(2, 15)) * 9.81;

so combine usual way:
stuff before setup goes together
stuff in setup() goes together
stuff in loop() goes together
functions stay separate
no code exist outside of function (and setup() , loop() functions)
clear duplicate uses of pins, variable names.
confirm end functionality.
