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
Build using CMAKE with the appropriate command. (Check READ.ME file for ZP3.5) Building inside STM32CubeIDE will give errors as it does not build the code using CMAKE.
When flashing, go to debug configurations and change the C/C++ Application to point to ZeroPilot.elf
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. Set a breakpoint in the callback function and make sure it is being hit. Otherwise, unplug and replug the tracer or use a different board for testing.
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
