[Amforth] TWI question

[Jan K. <kro...@ho...>]

Hello,

I try to convert the arduino source :

Wire.beginTransmission(THERM);    
Wire.send(0);
Wire.endTransmission();
Wire.requestFrom(THERM, 2);    <======????
Temperature_H = Wire.receive();  <=====????
Temperature_L = Wire.receive();  <=====????

into the amForth without any success.

In this case I set the register index at zero, and I won't to read two bytes.

Can someone help me with this?

Thanks in advance and regards.

Cheers

Jan Kromhout

Did you check the following code from the repository?

http://amforth.svn.sourceforge.net/viewvc/amforth/applications/ewlib/

The I2C snippets do exactly what you want (IMHO)
