Register I2C Simulation Data
To receive data, it is necessary to register the same amount of dummy data.
□ I2C Master Mode
At first, set the slave address (including a read/write bit) and then set transmission/reception data. Start/
stop sequence are added automatically at the beginning and end of data.
To receive data, it is necessary to set the same amount of dummy data.
Touch “PE/MP” or press [SHIFT]+[E] to insert a re-start sequence.
e.g.1 : Transmit data (41h, 42h, 43h) to the slave address “1010000b” (7bit).
Register in the data table: A0h 41h 42h 43h
A0h (1010000b): Write request to the slave address
41h 42h 43h : 3byte of transmission data
e.g.2: Receive 3 byte of data from the slave address “1010000b” (7bit).
Register in the data table: A1h 00h 00h 00h
A1h (10100001b)
：
Read request to the slave address (bit 0=1)
00h 00h 00h
：
3byte of dummy data
e.g.3: Transmit data (41h, 42h, 43h) to the slave address “1010000b” (7bit), and then receive 3 byte of data
from the slave address.
Register in the data table: A0h 41h 42h 43h A1h 00h
00h 00h
A0h (1010000b): Write request to the slave address
41h 42h 43h : 3byte of transmission data
A1h (1010000b): Re-start + Read request to the
slave address (bit 0=1)
00h 00h 00h : 3byte of dummy data
Move the cursor to the “A1” then touch “PE/MP”.
□ I2C Slave Mode
Set the transmission data to send after receiving a request from the master. To receive data, it is necessary
to register the same amount of dummy data. Registered data (more than 1byte) is used repeatedly when it
receives data from the master, and when it transmits data after receiving a request from the master.
e.g.1 : Transmit 31h, 32h, 33h, 31h, 32h, 33h after receiving 6 byte of send request from master.
Set the I2C salve address (7bit address) : 1010000b from [MENU]->“
Configuration”.
Simulation mode: SLAVE
Address bit: 7 BIT
Slave address: 0A0
Register in the data table: 31h, 32h, 33h, 31h, 32h, 33h
Registering only “31h, 32h, 33h” in the transmission data table will be the same result.
e.g.2: Receive 16 byte of data from master.
Register in the data table: 00h
If there is nothing in the data transmission table, data cannot be received.
To receive data, press [RUN] to start measuring and then press a corresponded key with data transmission data table
No. before starting the communication from master. (Manual mode)
