Hi Mike, I had a look at what you requested and I since what you are doing is more advanced I thought of the simplest way to add two procedures for advanced users so that you can do anything you want. BTW. I noticed that setting the precharge to 0 is an invalid value according to the datasheet.
These are the two procedures I added to the library: procedure ssd1306_send_command(byte in command) procedure ssd1306_send_command_parameter(byte in command, byte in parameter) This version wil be in the next bee package (ready on Sunday). Kind regards, Rob ________________________________ Van: [email protected] <[email protected]> namens Rob Hamerling <[email protected]> Verzonden: zaterdag 17 oktober 2020 14:29 Aan: [email protected] <[email protected]> Onderwerp: Re: [jallib] Re: JAL Library for SSD1306 graphic display module. Hi Mike, On 14/10/2020 16.24, 'Mike' via jallib wrote: Just a note...The dimming ability of the display can be greatly extended by using the SETPRECHARGE and SETVCOMDETECT commands. I am able to make the display very dim - much dimmer than just using the contrast - by setting all three parameters to zero. This could be very useful for battery powered devices. I'm using ssd1306 (and sh1106) in other environments (ESP8266/ESP32 with Micropython, and Teensy 4.0 with C/C++). I am interested to extend some of the oled support libraries for these environments for better contrast-control. But the datasheets were not helpful (enough) for me. Could you point me to more elaborate information w.r.t. the above commands (meaning, explanation and format)?
