Hello, I'd like to ask a little bit help. I downloaded the mcb517_i2c aplication note. I try to read the LM75 tempereture sensor with the bit_bang i2c routines. The problem is... There is a 16 bit temperature register and I can read only the high byte . I use the following program . . unsigned char data_in; i2c_start(); i2c_write(0x91); data_in=i2c_read(); i2c_stop(); I try to use the unsigned int instead unsigned char and modified the i2c_read routin to read 16 bit but no succes. Any advice? Cheer George
You can also test the LM75 with my I2C-Simulation DLL. You'll find it in http://www.c51.de part µVision2 DLLs
