TACOS
This is the Trajectory Analysis Control OS (TACOS) that serves as a starting point for developing TACOS-based projects, by implementing threads in the App directory. TACOS is a subset of the features provided by ALPAKA. In particular, TACOS consists of the STM32-specific components of sta-core, rtos-2 and rtos2-utils.
Setting Up TACOS
Add this as a library an existing CubeIDE project using FreeRTOS. Generally, we advise you to add it as a submodule. Make sure that you add the include paths for Tacos, i.e. sta-core and rtos2-utils, to the project with the following steps:
Properties -> C/C++ General -> Paths and Symbols -> Includes -> GNU C -> Add...
Properties -> C/C++ General -> Paths and Symbols -> Includes -> GNU C++ -> Add...
Properties -> C/C++ General -> Paths and Symbols -> Source Location -> Add Folder...
Create a new thread via the project's IOC and call startALPAKA() from this thread. If your thread is called defaultTask
, the corresponding StartDefaultTask
generated in Core/Src/freertos.c
should look like this:
void StartDefaultTask(void *argument)
{
/* USER CODE BEGIN StartDefaultTask */
extern void startALPAKA(void *);
startALPAKA(argument);
/* Infinite loop */
for(;;)
{
osDelay(1);
}
/* USER CODE END StartDefaultTask */
}
Configuring TACOS
Be sure to add a "config.hpp" to the App/Inc/sta directory. This file could look like this:
#ifndef INC_STA_CONFIG_HPP_
#define INC_STA_CONFIG_HPP_
// Use the STM32F411 microprocessor.
#include <sta/devices/stm32/mcu/STM32F411xE.hpp>
// Doesn't really do too much right now. Has to be added for successful compilation.
#define STA_PRINTF_USE_STDLIB
// Enable debug serial output and assertions.
#define STA_ASSERT_FORCE
#define STA_DEBUGGING_ENABLED
// Activate the timer for microsecond delays.
// #define STA_STM32_DELAY_ENABLE
// #define STA_STM32_DELAY_US_TIM htim1
// Settings for the rtos-utils
#define STA_RTOS_SYSTEM_EVENTS_ENABLE
// #define STA_RTOS_SYSTEM_WATCHDOG_ENABLE
// #define STA_RTOS_WATCHDOG_ENABLE
// Settings for TACOS
#define STA_TACOS_MANAGER_PRIORITY osPriorityNormal
#define STA_TACOS_STATEMACHINE_PRIORITY osPriorityNormal
// Statemachine settings. Here, we only have a single state which is also the initial state.
#define STA_TACOS_NUM_STATES 3
#define STA_TACOS_INITIAL_STATE 0
#endif /* INC_STA_CONFIG_HPP_ */
