In a project I want to use one of these tiny display. First I bougth an I2c and made a test, it work fine, but when I see other who had used them with Arduino IDE it is very slow programmed with FC8 no change when I increase the Baudrate.
Then I bougth a SPI and make the same test, It is a little bit faster but still slow compared with others who used Arduino IDE. Even if I set the Fosc/4.
Is there something I forgot in config or properties or is it max speed FC8 can do with these devices, please.
