STM32H747i-Disco Display

[AStew.1]

I am using an STM32H747i-Disco board for a time critical application. I would like to periodically output simple text messages to the display.but I don't want to use an RTOS, so TouchGFX is not an option. In LCD.c there appear to be no functions to simply display text at a location on the screen.

Do such functions exist? If so where?

So you have some timer, to decide when a message should be coming. Then - just show it.

Whats your LCD.c ? any kind of lcd driver lib ? There should be something like :

WriteString(uint16_t x, uint16_t y, const char *str, FontDef font, uint16_t color, uint16_t bgcolor)

In the BSP package for STM32H747i Disco there is "stm32h747i_discovery_lcd" it only has functions to draw lines, no "WriteString" function.
