[oopic] Re: Controll RFID module over I2C bus

okay lets ignore the previous code and work at one problem at a time.
Say i want to replicate code like the example i posted in the first
part of my post. With start signal, address,length,command,stop. Can i
just use simple layout like
i2c.value=ff *what variable type goes here? should i send it as 255?
i2c.value=00 *FF 00 is the start sequence for the RFID module it seem
i2c.value=42 *developer for i2c stated address is 42 but with 7bit
addressing mode you shifted right so 84 for write and 85 for read
i2c.value=81 *get firmware command
i2c.value=82 *checksum

places where it confuse me is PicMicro state the address of the slave
during the transmission sequence. OOpic seem to do this in the i2c.node
