mongoose-os-libs / ssd1306 Goto Github PK

MongooseOS is wonderful, mjs is very sweet, the only pity is mjs can't use many useful libraries directly.

According to the document, it is possible writing wrapper to use struct argument C functions, but I have to say it too hard for normal users...

I get an error when call drawString function.
As far as I understood, the function should return _drawString instead of _drawStringColor.

drawString: function(x, y, txt) {
return this._drawStringColor(this._oled, x, y, txt);
},

If you are using a 128x32 0.91" OLED display, you have to set the com_pins configuration to be 0x02. With the default value of 0x12, the output on the display is compressed.

config_schema:
- ["ssd1306.com_pins", "i", 0x02, {title: "Screen COM pins configuration, depends on physical attachemnt of the panel to the chip; 0x02, 0x12, 0x22 or 0x32 are valid values"}]

Can you add a note to the README?

When displaying text, there is a log message on loglevel INFO for each single character. If needed this should be done on LL_TRACE or maybe LL_DEBUG. Logging this on LL_INFO
appears to be a bug.

This issue is solved by #3 and #6
