Unable to build with DHT from PlatformIO #210
Description
When compiling a project with PlatformIO, targeting Arduino Mega and Arduino Due, it seems that it is unable to find the DHT sensor driver.
Here's the code:
#include "simba.h"
#include "pins.h"
#include "config.h"
#include "events.h"
#include "sensor_threads.h"
#ifndef DHT_SENSOR
// Omitted
#else
static THRD_STACK(dht_sensor_stack, 256);
void *dht_sensor_thread(void *arg_p){
dht_module_init(); // Mega - W;Due - E:Implicit function declaration
struct pin_device_t pin_targets[] = DHT;
int pincount = sizeof(pin_targets)/sizeof(struct pin_device_t);
struct dht_driver_t sensors[pincount]; // E:Incomplete element type
for (int i=0;i<pincount;i++){
dht_init(&sensors[i], &pin_targets[i]); // Mega - W;Due - E:Implicit function declaration
}
while (1) {
int sensor_count=pincount;
float temperature_acc=0;
float humidity_acc=0;
for (int i=0;i<pincount;i++){
float temp, humidity;
int res = dht_read(&sensors[i], &temp, &humidity); // Mega - W;Due - E:Implicit function declaration
if (res != 0){
std_printf(
FSTR("Read failed from DHT sensor %d with %d: %S\n"),
i,
res,
errno_as_string(res) // Mega - W;Due - E:Implicit function declaration
);
sensor_count--;
continue;
}
temperature_acc+=temp;
humidity_acc+=humidity;
}
float temp = temperature_acc/sensor_count;
float hmid = humidity_acc/sensor_count;
if (temp > 30){
int mask = MAXTEMP_EVENT;
event_write(&temp_event, &mask, sizeof(mask));
}
if (temp < 10){
int mask = MINTEMP_EVENT;
event_write(&temp_event, &mask, sizeof(mask));
}
if (hmid > 50){
int mask = MAXHMID_EVENT;
event_write(&hmid_event, &mask, sizeof(mask));
}
if (hmid < 10){
int mask = MINHMID_EVENT;
event_write(&hmid_event, &mask, sizeof(mask));
}
}
}
#endif
void register_threads(){
#ifndef DHT_SENSOR
thrd_spawn(temp_sensor_thread, NULL, 2, temp_sensor_stack, sizeof(temp_sensor_stack));
thrd_spawn(hmid_sensor_thread, NULL, 2, hmid_sensor_stack, sizeof(hmid_sensor_stack));
#else
thrd_spawn(dht_sensor_thread, NULL, 2, dht_sensor_stack, sizeof(dht_sensor_stack));
