In your code you create a task called TaskBlink, where is TaskBlink in the code you posted?
If in setup you create a task:
xTaskCreatePinnedToCore( fFindDewPointWithHumidity, "fFindDewPointWithHumidity", 23000, NULL, 3, NULL, 1 );
Then the task needs to be defined:
void fFindDewPointWithHumidity( void *pvParameters )
{
TickType_t xLastWakeTime = xTaskGetTickCount();
const TickType_t xFrequency = 1000;
for ( ;; )
{
float temperature = oTemperature;
float humi = oHumidity;
//Celcius
float ans = (temperature - (14.55 + 0.114 * temperature) * (1 - (0.01 * humi)) - pow(((2.5 + 0.007 * temperature) * (1 - (0.01 * humi))),3) - (15.9 + 0.117 * temperature) * pow((1 - (0.01 * humi)), 14));
log_i( "%f", ans );
xLastWakeTime = xTaskGetTickCount();
vTaskDelayUntil( &xLastWakeTime, xFrequency );
}
vTaskDelete( NULL );
}
That does not define the task.
