I am trying to work on a project where I am using the MCB1700's display. Here, I get the joystick input and enter one of the apps that I display in the main screen. So, I have a Photo Gallery and a retro Game. For the game part, just to be creative I want the user to be able to choose a level: Easy or Hard and then he/she can enter the Game. I am trying to use multi-threading here in this instance with RTX v1 and CMSIS-RTOS v1 API. I am having some difficulty here, I basically have three functions here: joyStick, selLev and displayLev. When I run this code in debg mode, I see that all threads run but when I run it on display, I see only joyStick and selLev running but even here, I cannot toggle the joystick. I am also pasting the copy of the code. Any help would be great.
Code:
