Getting Code Running

Add these lines of your code to main.cpp.

/* Private includes ----------------------------------------------------------*/
/* USER CODE BEGIN Includes */
#include "SBUSReceiver.hpp"
#include "RCReceiver_config.hpp"
/* USER CODE END Includes */

/* USER CODE BEGIN 2 */
  SBus sbus_data;
  RCControl control_data;
  /* USER CODE END 2 */

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
    /* USER CODE END WHILE */
  	sbus_data = sbus_pointer->GetSBUS();
  	control_data = sbus_pointer->GetRCControl();
  	/* USER CODE BEGIN 3 */
  }

Building and Flashing

1. Build using CMAKE with the appropriate command. Building inside STM32CubeIDE will give errors.

2. When flashing, go to debug configurations and change the C/C++ Application to point to ZeroPilot.elf

3. Also, select the “Disable auto build” option.

Troubleshooting

If all the values do not change and have a value of 1000 even when you move the controller, your ioc is probably not configured correctly. Otherwise, unplug and replug the tracer.

To Do

• Configure Nucleo pins
• Test data with a logic analyzer and RC controller
• Debug with interrupts
• Transmit receive signal to nucleo to check if the data is similar
