Push a font up by a small number of pixels

[russ627]

Hi,

I am using u8x8_font_inb46_4x8_n on a 256x50 display unfortunately the bottom part of the numbers are cut off, is there an easy way of moving the font up by a couple of pixels? Its easier to see the problem in the attached picture.

Thanks in advance!

Decrease the y position.

Hi again, I moved to a esp32 devkit 1 as nano does not have the space for the u8g2 libraries and the u8x8 works as expected however when I try to compile the u8g2 library I get this error message

***_initializing argument 1 of 'U8G2_GP1287AI_256X50_1_4W_SW_SPI::U8G2_GP1287AI_256X50_1_4W_SW_SPI(const u8g2_cb_t, uint8_t, uint8_t, uint8_t, uint8_t, uint8_t)'

I know that the esp32 uses a different compiler that is a lot more fussy about types and have managed to knife and fork simple programs so that the datatypes match but this is a bit complex for me. Is it a simple fix?

Which version of u8g2 do you use? Did you use an official version for Arduino IDE? All in all, answers are difficult without knowing more about the code. At least for me u8g2 compiles without problem.

Hi, Its Arduino IDE 2.1.0 on Linux and the library is 2.33.15 from arduino library. The processor is ESP32 DEVKIT V1 If I compile it for this processor it gives errors but if I change the board to Mega 2560 it will compile without errors.

I tried to install esp32 within my own Arduino IDE, but failed until now. I will create an issue for this. However I am not sure, when I will find time to test this for myself.

#2177

I did some more tests. The above mentioned error does not appear on my test system.
I will close the issue.

Hi,

It fails on this line in my system,, I have downloaded 2.33.8 which on the latest arduino update installs OK.

what are you using?

OK got it, the arduino version does not have an example so the format is wrong and at the time the latest version on githum would not install but after an upgrade today does.
