FAQ / Frequently Asked Questions

Please teach me how to translate the data when the measured data of I2C bus is printed or converted into text format on the PC by using LE-series.
Example: Printed data
(Normal)
SD: A00001 A141
>>A00001>>A1##<<

(Translated)
A0a=>00a01a A0a<=41n

As follows, it indicates the finish when Master sends 2 bytes of 00h and 01h to Slave address, and receives 41h of 1byte.


[S][ADDR(A0)][W(0)][A][DATA(00)][A][DATA(01)][A][S][ADDR(A0)][R(1)][A][DATA(41)][N][P]

*Meaning
[S]:Start sequence(>>)
[P]:Stop sequence(<<)
[ADDR]:Address
[DATA]:Data
[A]:ACK(a)
[N]:NAK(##, n)
[R]:Reception at Master side (<=)
[W]:Transmission of Master side (=>)
* Codes in parentheses are indicated in the printed data.
