Finished experimental code to drive the German HendiControl board. Added BoilPower and RampPower buttons during the while boil process. RampPower (going to boil power) is now adjustable. Added PWM driver code to the driver task.
/** * @file task_sdcard.c * @brief SD/MMC driver. This driver is for a slot for the user on * the front panel. It will detect an inserted card and then * mount it. It also detects the removal of the card and then * unmounts it. Be carefull, only do this in the main menu. * Also, brew logging is handled here and finished brewlogs * are copied to the SD card if it is mounted. * Recipes to import must go into the /sdcard/recipe folder * and have extension .xml and the contents be a beerxml file. * Backup and restore is also done to this card. */ #include "vfs_fat_internal.h" #include "driver/sdmmc_host.h" #include "driver/sdspi_host.h" #include "sdmmc_cmd.h" #include "diskio_impl.h" #include "diskio_sdmmc.h" #include "config.h" SDCARD_State *sdcard_state; ///< SD card status JSON_log *json_log; ///< JSON log array EventGroupHandle_t xEventGroupSDcard; ///< SD card events. static const char *TAG = "task_sdcard"; static sdmmc_card_t* s_card = NULL; static uint8_t s_pdrv = 0; static char * s_base_path = NULL; static uint8_t pdrv = FF_DRV_NOT_USED; #define SDCARD_HOST_SLOT VSPI_HOST ///< HSPI_HOST is used by the TFT #define SDCARD_PIN_NUM_MISO 2 ///< MISO pin #define SDCARD_PIN_NUM_MOSI 15 ///< MOSI pin #define SDCARD_PIN_NUM_CLK 14 ///< CLOCK #define SDCARD_PIN_NUM_CS 13 ///< Chip select pin #define SDCARD_DMA_CHANNEL 2 ///< Channel 1 is used by the TFT const int TASK_SDCARD_LOG_CLEAN = BIT0; ///< Clean spiffs logfile directory const int TASK_SDCARD_LOG_CLOSE = BIT1; ///< Close the logfile. extern time_t now; extern struct tm timeinfo; extern uint32_t TimeBrewing; extern bool System_TimeOk; void log_msg(const char *tag, const char *format, ...) { char *outstr, logfn[64], stamp[32]; va_list va_ptr; FILE *fp; outstr = calloc(1024, sizeof(char)); va_start(va_ptr, format); vsnprintf(outstr, 1023, format, va_ptr); ESP_LOGI(tag, "%s", outstr); if (System_TimeOk && sdcard_state->card_present == true) { snprintf(logfn, 64, "/sdcard/w/log/sys%04d%02d%02d.log", timeinfo.tm_year+1900, timeinfo.tm_mon+1, timeinfo.tm_mday); snprintf(stamp, 31, "%02d-%02d %02d:%02d:%02d", timeinfo.tm_mday, timeinfo.tm_mon+1, timeinfo.tm_hour, timeinfo.tm_min, timeinfo.tm_sec); fp = fopen(logfn, "a+"); if (fp) { fprintf(fp, "%s %s: %s\n", stamp, tag, outstr); fclose(fp); } } va_end(va_ptr); free(outstr); } void log_begin(time_t t) { struct tm timeinfo; /* * If there is an open logfile from an crashed brew, open that one. */ if (!
