Vector font with ugly result on SSD1306

Hello,

I come here to find an answer to a problem I meet with the "Vector" font on my screen SSD1306.

Is it a normal result, or is there a problem somewhere?

Here is the result I get:

• I admit that it remains legible but the result is still very ugly in the irregular contours of the characters.

If this is totally normal and that it is the same resource you get, would you please a solution with another type of fonts that would have a better result and similar size.

I have already traveled the wiki and the Espruino doc, so please, the answers with only the link to the page of the available fonts is not necessary.

Also, do you know if there is a way to use a font already included in an Arduino library, such as:

• https://github.com/iliapenev/ssd1306_i2c
• https://github.com/ThingPulse/esp8266-oled-ssd1306

I think it was @allObjects that detailed this, but I'm not able to locate the thread just yet.

In the mean time, this might help compliments of @nebbishhacker :

Are you running the latest Espruino firmware? There was a huge improvement with version 2v06.

@MaBecker , thank you for your reply!

I would like but unfortunately i performed several tests and the code only works with 1v95 firmware, the project is getting dated and the code has not been updated.

My little knowledges doesn't allow me (for the moment, because I learn quickly) to update the code so that it works on a more recent firmware.

Why is that?

If you run on ESP32 you can disable ble to have more memory, or use a ESP32 wroom that comes with srsam without any firmware modifications.

@MaBecker ,

Yes sorry, I forgeted to tell you that I use the code of this project:

• PhotoPizza

And it's in the code of this project that it use "vector" font.

But I'm very interested in how to disable the ble to save space. Could you tell me the procedure please?
