reverting from SoftwareI2CLibrary to Wire library (help with wire lib)

Using Arduino Programming Questions
#1

I have been using http://playground.arduino.cc/Main/SoftwareI2CLibrary till now.
Now another library I am using, (display related) is hardcoded to using Wire.

The old code can be summed up like:

#define SDA_PORT PORTC
#define SDA_PIN 3
#define SCL_PORT PORTC
#define SCL_PIN 4
#define I2C_SLOWMODE 1
#include <SoftI2CMaster.h>
byte deviceAddress = 11;
#define CYCLE              //feature to read
void setup()
 {
 i2c_init();
}

void loop() {
//read a word
  i2c_start(deviceAddress << 1 | I2C_WRITE);
  i2c_write(CYCLE);
  i2c_rep_start(deviceAddress << 1 | I2C_READ);
  byte b1 = i2c_read(false);
  byte b2 = i2c_read(true);
  i2c_stop();
}

it just works

now I tried to convert that to use Wire library:

#include <Wire.h>
byte deviceAddress = 11;
#define CYCLE              //feature to read
void setup()
 {
Wire.begin();
}


void loop() {
//read a word
  Wire.beginTransmission(deviceAddress);
  Wire.write(CYCLE);
  Wire.endTransmission();
    
  Wire.requestFrom(deviceAddress,2);
  byte b1=0;
  byte b2=0;
  while(Wire.available()) {
  b1 = Wire.read();
  b2 = Wire.read();
 }

needless to say, it does not work - what am I doing wrong ?

The biggest difference I see between the software and the hardware version is that you send a STOP in the hardware version.

Change to

Wire.endTransmission(false);

to not stop the transmission.

Might not be the problem but it's a difference.

It is USELESS to say “it does not work”. You have shown NOT A SHRED of evidence that the code is not working flawlessly.

septillion: thanks - it work fine now.
