OLED driver fixes (#10377)

2020-10-03T18:44:19Z

* Fix dirtying in oled_write_pixel() Set the dirty bit for the block only if oled_write_pixel() actually changed the buffer state. Without this check oled_write_pixel() could not be used inside the oled_task_user() code using the “redraw always” style, because the blocks touched by oled_write_pixel() would always appear dirty, and oled_render() would not proceed beyond the first such dirty block. * Fix oled_write_pixel() with 90/270 degree rotation Use oled_rotation_width instead of OLED_DISPLAY_WIDTH, so that a rotated display would be handled correctly. * Fix compilation with custom OLED_BLOCK_COUNT and OLED_BLOCK_SIZE Some OLED sizes (e.g., 64×48) may require a nonstandard value of OLED_BLOCK_COUNT. The documentation says that this value may be redefined in config.h, but actually trying to redefine it caused a compile error, because the macro was redefined in oled_driver.c. Make the OLED_BLOCK_COUNT definition in oled_driver.c respect any user override, and do the same for OLED_BLOCK_SIZE just in case. * Fix handling of out-of-range bits in oled_dirty If a custom OLED_BLOCK_COUNT value is specified, some bits in oled_dirty may not correspond to existing blocks; however, if those bits are set somewhere (e.g., by code with sets oled_dirty to ~0 or even -1), oled_render() would try to handle them and could access memory beyond oled_buffer and perform hardware operations with out of range values. Prevent this by masking off unused bits in oled_render(), and also avoid setting those bits in other functions. * Fix potentially wrong dirtying in oled_write_char() oled_write_char() tried to mark the position just beyond the written character as dirty; use (OLED_FONT_WIDTH - 1) to dirty the last position still belonging to the character instead. * Fix `#define OLED_BLOCK_TYPE uint32_t` on AVR Using uint32_t as OLED_BLOCK_TYPE did not work properly on AVR, because some bit shifts were performed using 16-bit int. Add explicit casts to OLED_BLOCK_TYPE to those shifts.
