C Bus Access
1) I
2) Slave Address
3) Write Format
4) Read Format
ex)
ST
Write measurement command and Read measurement result are done by I
specification of I
Slave Address is 2 types, it is determined by ADDR Terminal
BH1710FVC is not able to accept plural command without stop condition. Please insert SP every 1 Opecode.
