how to display data with PROS like Brain.Screen.printAt() of vexcode PROS is using Atom as its editor, which is much more conventient to use. but i can find PROS api do print simple things, it has LVGL, but not that friendly to use. and the Legacy LCD Emulator is not that cool . thanks

lv_obj_t * label=lv_label_create(lv_scr_act(),nullptr); lv_label_set_text(label ,"Hello ,Luo Qiang!"); You can try my graphics library. [image] GitHub - 3038922/ncrapi: 新世纪机器人学院 VEX-EDR V5图形框架新世纪机器人学院 VEX-EDR V5图形框架. Contribute to 3038922/ncrapi development by creating an account on Gi…

I would also look at this thread that talked about the LVGL Library Questions about LVGL & examples of V5 displays

This is what I use for making my auton selector but it can print anything you want on to the screen. For diagnostic stuff I use printf and the pros terminal. Which can be accessed with prosv5 terminal or through atom. pros::lcd::initialize(); //This only needs to be called once at the start of y…

I think @vex_lq doesn’t want to use the LCD emulator. I would recommend going to the LVGL GitHub page and going through the root code to form a better understanding of how the code works. That and using the examples.

Or instead of going through the source you coukd just read the docs: https://docs.littlevgl.com Keep in mind that the version of LVGL in PROS is 5.1.1, not the latest 5.3, so there may be some discrepancies between the docs and reality (images especially).

Here is a link to a pros project that show LVGL button and text examples.

right, i dont like the LCD emulator,

better than nothing… //user_display.h #ifndef USER_DISPLAY_H #define USER_DISPLAY_H #include “main.h” #include <stdarg.h> #include <string.h> extern lv_obj_t *label[11]; extern int line; extern bool display_print(int16_t line, const char *fmt, …); extern void user_display_init(); #endif /…

That’s very similar to the what one of the coders on the team I coach did. It looks like you have multiple “labels” where he only has one but stores multiple lines of text in a string array to be printed on different lines of the label. I’ve tried to get him to publish it but he’s spends all his fr…

Avoid C-style strings, they are difficult and messy to use.
