Hi.
I am developing using nRF52832 & ST7789 round LCD.(softdevice : s112, SDK version : nRF5_SDK_17.0.0)
Currently, I am trying to develop using the gfx library, but there is a problem.
The Interface method used SPI Interface.
I proceeded gfx_init normally using the gfx_initialization() function.
The method of verification was to check the SPI with the oscilloscope, and it was also confirmed that the display did not turn on when the command called DISPOFF (display_off) was operated in the command list, and the screen rotated 90, 180, 270 well using the st7789_rotation_set() function.
I also confirmed that it works normally using the nrf_gfx_screen_fill() function.
But the problem is that text doesn't appear on LCD.
The text_print() function provided by nRF5_SDK_17.0.0/examples/peripheral/gfx does not output text.
I don't know what the problem is.
Help me.
Thank you.
