// devices_common.cpp's create_st7123_touch). No custom init-sequence is supplied - unlike ST7123,

|
// the M5Tab5 UserDemo runs the ST7121 panel with the esp_lcd_st7121 component's own built-in
|
|
// default bring-up sequence (see esp_lcd_st7121.c's vendor_specific_init_default), so
|
|
// init_sequence stays null here too. Timing values (vsync_pulse_width/back_porch/front_porch) are
|
|
// per the UserDemo's is_st7121 branch in bsp_display_new_with_handles_to_st7123() - the only
|
|
// values that differ from V2/ST7123.
