Version 0.3.20 fix for equipment records create and delete.
/** * @file task_ds18b20.h * @brief The FreeRTOS task to query the DS18B20 sensors on one or two * one-wire busses. Each bus must have only one sensor. That way * we don't need to care about the DS18B20 internal ROM address. * The task will update the DS18B20_State structure. * * Using a compile setting with make menuconfig it is possible to compile * a simulator instead of real hardware sensors. The simulator includes * fake kettles so that the temperature actually changes with the * activation of the kettle Solid State Relays. Only usefull for developers. */ #ifndef _TASK_DS18B20_H #define _TASK_DS18B20_H /* * Error codes in this task */ #define DS18B20_ERR_NONE 0 ///< No errors #define DS18B20_ERR_NOSENSOR 1 ///< No sensor detected #define DS18B20_ERR_TOOMANY 2 ///< Too many sensors #define DS18B20_ERR_CRC 3 ///< CRC read error #define DS18B20_ERR_READ 4 ///< Generic read error /** * @brief Structure containing the variables for the DS18B20 task. */ typedef struct { bool mlt_valid; ///< MLT sensor valid reading. double mlt_temperature; ///< Current MLT temperature. int mlt_error; ///< MLT error number. bool hlt_valid; ///< HLT sensor valid reading. double hlt_temperature; ///< Current HLT temperature. int hlt_error; ///< HLT error number. } DS18B20_State; /** * @brief The FreeRTOS task to update the DS18B20 temperature sensors. */ void task_ds18b20(void *); #endif
