Python the LCD (ACM1602NI) connected to the Raspberry Pi
I tried to connect the lcd display (ACM1602N1) by referring to the site above.
After configuring the kernel module, i2c-bcm2708, i2c-dev to load, you can find the
dmesg | grep i2c
I can't find a description of bcm2708_i2c when I run .
Instead, i2c-bcm2835 was running, so I tried to run i2cset as it was, but
I suspect that the write failed, so it is not compatible with the lcd display.
I have confirmed the wiring defect, but how can I activate bcm2708_i2c?
Or is the difference between bcm2708 and bcm2835 irrelevant?
Thank you for your cooperation.

Check your Rapsberry pi version.
bcm2708 is the CPU used in Raspberry Pi Model B (Kernel 4.4 series) and not in Raspberry Pi 2 Model B.
Note: Note: How to Determine Raspberry Pi Board Revision
Also, bcm2835 seems to be related to Broadcom's SoC chip BCM2835 which is included in the first generation Raspberry Pi.
Raspberry Pi 2 Model B uses "BCM2836".

This seems to have caused confusion because the information on the site you are referring to is old.
Update rapsbian to the latest version.Also, wouldn't it be better to use the following article to enable I2C?
