Function Documentation

Error_Handler()

void Error_Handler

(

void

)

This function is executed in case of error occurrence.

Return values

None

HAL_TIM_PeriodElapsedCallback()

void HAL_TIM_PeriodElapsedCallback

(

TIM_HandleTypeDef *

htim

)

Period elapsed callback in non blocking mode.

Note

This function is called when TIM6 interrupt took place, inside HAL_TIM_IRQHandler(). It makes a direct call to HAL_IncTick() to increment a global variable "uwTick" used as application time base.

Parameters

htim	: TIM handle

Return values

None

HAL_UART_RxCpltCallback()

void HAL_UART_RxCpltCallback

(

UART_HandleTypeDef *

huart

)

Callback function for the UART reception.

This function is called when a character is received from the UART3 peripheral. The received character is stored in the rxBuffer and echoed back to the terminal console connected to the UART2 peripheral. Supports backspace and Enter characters.

Parameters

huart

Return values

None

Note

The expected UART instance to receive data is USART3, which is connected to the HC-05 Bluetooth module. The UART2 instance is used to echo the received characters back to the terminal console, which corresponds to the USB virtual COM port from the Nucleo board.

main()

int main

(

void

)

The application entry point.

Return values

int

MOVER AQUÍ

SelectInputChannel()

void SelectInputChannel

(

uint8_t

channel

)

Selects the input channel of the Mux.

Sets the appropriate pin values to let a signal come from the desired channel, which can be 1 out 8 input channels

Parameters

channel

Channel to be selected

Return values

None

SelectOutputChannel()

void SelectOutputChannel

(

uint8_t

channel

)

Selects the output channel of the DMux.

Sets the appropriate pin values to pass a signal through the desired channel, which can be 1 out 8 output channels

Parameters

channel

Channel to be selected

Return values

None

StartExecuteCommand()

void StartExecuteCommand

(

void *

argument

)

Function implementing the ExecuteCommand thread.

Parameters

argument

SystemClock_Config()

void SystemClock_Config

(

void

)

System Clock Configuration.

Return values

None

Initializes the RCC Oscillators according to the specified parameters in the RCC_OscInitTypeDef structure.

Initializes the CPU, AHB and APB buses clocks

ExecuteCommand_attributes

const osThreadAttr_t ExecuteCommand_attributes

Initial value:

= {
  .name = "ExecuteCommand",
  .stack_size = 128 * 4,
  .priority = (osPriority_t) osPriorityNormal,
}
