Function Documentation

adc_task_run()

void adc_task_run

(

ADCTask *

adc_task

)

Executes the current state of the ADC task.

Executes the current ADC task state.

This function checks the validity of the current state, then calls the corresponding state handler from the state's function pointer list.

Parameters

adc_task

Pointer to the ADCTask structure containing state and hardware info.

adc_task_state_0_init()

void adc_task_state_0_init

(

ADCTask *

adc_task

)

Initializes the ADC task.

Initializes the ADC task (state 0).

Sets the task's state to 1 and starts the ADC with DMA to fill the dma_buffer.

Parameters

adc_task

Pointer to the ADCTask structure.

adc_task_state_1_read()

void adc_task_state_1_read

(

ADCTask *

adc_task

)

Reads ADC values from DMA buffer and assigns them to respective photo resistors and controllers.

Reads and assigns values from the ADC DMA buffer (state 1).

This function maps each DMA buffer value to its corresponding sensor's adc_val.

Parameters

adc_task

Pointer to the ADCTask structure.
