i have recently delved into the world of dallas semiconductors and have come across the ibuttons (a keyring form of data storage/ ID requiring a simple 1 wire touch to a pod to be read) i have adopted the commands in the proton compiler as the same as that of the 1wire dallas command for example reading the temperature from the 1 wire thermo semiconductor. i have had reasonable success with reading the serial numbers of these devices however the current code patten is just looping on owrites and oreads and if the button is placed on the pad at the right moment (im assuming ) then it will read the 64 bit code which is great as i am developing a security access panel involving a RTC for time stamping but just need a reliable basic code to read these things 1st time round. is it possible to put the program into a trap until it detects the presence of the buttons? has any body had any experiences of these in other suitations?
