CH1116 driver

[olikraus]

There is a discussion for on the CH1116 driver IC here:

#2030

There might be a constructor for this driver in the future.

Meanwhile use SSD1309 or SH1106 constructor

• CH1116 with external VPP power: Use SSD1309 constructor
• CH1116 with internal VPP generation (Charge Pump): Use SH1106 constructor

Often it is not visible from outside, which constructor is required. If the display only has a flex cable connections, then probably the SH1106 constructor should be used. If the display is mounted on a PCB and the PCB includes a step up converter circuit, then the SSD1309 must be used.

How can I modify the SH1106 code to make it compatible with the CH1116?

[olikraus]

From my perspective it should be compatible already. What else should be changed?

I can light up the SSD1306 using the initialization code for the SH1106 with a 128x64 resolution, but I can't get the CH1106 to light up with the same SH1106 configuration code. In theory, the SH1106 configuration should be compatible with the CH1106, but it doesn't seem to be working. I'm not sure what the issue is. Could you help me understand why this is happening?

Could you help me understand why this is happening?

Probably not. The only person who could tell you what to do is the display vendor. Only the creator of the display can tell you which init code to use.

According to my research, the initialization code for SH1106 only appears in the image mentioned above, and there is no initialization code for OLED anywhere else. How can I adapt it to CH11116 by modifying the initialization commands? Or which part of the code in the u8x8_d_ssd1306_128x64_noname.c file should I modify? Could you please help me with this?
