I need to usesimple ASCII commands which I plan to write a Automated test program in LabVIEW.
Should I getHA7E is a RS232 to 1-Wire interface? or can HA2 - RS232 1-Wire Host Adapter do the same function?
I have a DS1820 I need to use the CRC algorithm Specified by Dallas and
perform the following Tests:
Read 64 bit ROM of DS18S20, Resultant byte from CRC algorithm must match
the eight (last) byte of ROM.
Read 72 bit Scratchpad of DS18S20, Resultant byte from CRC algorithm must
match the ninth (last) byte of Scratchpad.
Next, I have to:
TH byte is downloaded from E2 memory to scratchpad. TH byte in scratchpad
TL byte is downloaded from E2 memory to scratchpad. TL byte in scratchpad
Finally, I need to read Temperature, which is read via data in
bytes 0,1,6 & 7 of the Scratchpad.
Can I accomplish this by MANUALLY typing the commands over the RS-232 Comm
Port from a PC?????
If anyone has any comments or am I taking the correct path? your help appreciated.
