Dummy I2C writes
---

---

This is an example capture of some dummy I2C traffic, where the master writes
to a slave (an RTC) at address 0x51 (or 0x2a, if the read/write bit is
included) in an infinite loop. The slave does not respond.

## Logic analyzer setup

The logic analyzer used was a ChronoVu LA8 (at 1MHz):

Probe RTC chip pin

---

0 (green) SCL
1 (orange) SDA

## Data

This is what the decoded data should look like:

- S Wr:0xa2 A 0x55 A 0x66 A P

- The abbreviations used above: S = Start, Wr = Write, A = ACK, P = Stop

The sigrok command line used was:

sigrok-cli -d 0:samplerate=1mhz --samples 8388608 \
 -p '1=SCL,2=SDA' -o a2_dummy_write.sr
