hi recently i tried example sketches for STM32 bluepill. the i2c work but SPI not compiling,

DisplaySSD1306_128x64_SPI display(PA3,{-1, PA4, PA2, 0,-1,-1}); Showing Error "narrowing conversion of '196' from 'int' to 'int8_t' {aka 'signed char'} [-Wnarrowing] ".

Hi,

Please, use Arduino environment pin numbers, but not STM32 pin id's. Arduino pin numbers start from 0, while STM32 pin id's start from 0xC0. Internally Arduino environment converts Arduino pins to your hardware platform.
