Struggling to get the Library work on a Raspberry Pi #62

Closed Emmpunkt closed 6 months ago

Emmpunkt commented 6 months ago

Hello, i can´t get the library work on a Raspberry Pi. I think i missed something, but i don´t know what it is. I installed/make Bitbank_I2C first. By installing the ss_oled i got some warnings, but no errors:

root@IRadio:/home/emmpunkt/iRadio/display/ss_oled/linux# make
cc -c -Wall -O2 -I../src -D_LINUX_ ss_oled.c
In file included from ss_oled.c:4:

ar -rc libss_oled.a ss_oled.o ;\
sudo cp libss_oled.a /usr/local/lib ;\
sudo cp ../src/ss_oled.h /usr/local/include

If i try to make the samples, i get this:

So i guess something is missing. Sorry no clue what it is.... Regards Michael

Hi Michael, Probably easier if you use the version of ss_oled I adapted for the Pico SDK: https://github.com/bitbank2/Pi_Pico_C_Projects

If you're using Arduino, then it will be easier to use my OneBitDisplay library.
