== LCD usage == |
|||
LCD menu has few main screens: |
|||
[[File:ESP32Kiln LCD sample.png|300px|center]] |
|||
* Menu screen - where you can select other screens (you can always go here with long press >0,7s) |
|||
** Main screen view - where you can see running program, it's parameters and progress |
|||
*** screen 1 - basic informations on program status (Ready,Run,Paused,Failed,Ended), current time, start and ETA time. Target step temperature, current kiln temperature, ambient temperature and housing temperature. Step number and type (_r_un/_d_well), heating percent time (this is how long heater is working in "PID_Window" time from prefs). |
|||
*** screen 2 - simple graph of the program and current progress (inverses colour with progress) |
|||
*** screen 3 - action screen: start, stop, pause, abort |
|||
** Program list - you can browser all programs on your SPIFFS "/programs" directory |
|||
*** program description - program summary screen with name, short description, max. temperature and program time. |
|||
**** program show - all program steps |
|||
**** program load - load selected program to RUN memory - this is going to be your running program |
|||
**** program delete - removes program from disk |
|||
** Quick program - allows you to create one step program with desire temperature, time and dwell |
|||
** Information - some basic informations like IP, WiFi status, WiFi type |
|||
** Preferences - shows current (in memory, not from disk) preferences |
|||
** Restart WiFi - restarts WiFi stack. Can be useful after preference change or if you lost WiFi connection. |
|||
** About - where to find more informations |
|||
** Restart - restarts device |

== Main view - program screen == |
|||
Since there are many information on first program screen, I'll try to explain them all here. Idea was to have every important information visible on single screen. |
|||
[[File:ESP32Kiln LCD MainView1.png|300px|center|alt=Main View|Main View]] |
|||
From the top and left: |
|||
* First line is the program name |
|||
* First field of the second line is current program status - it can be Ready, Running, Paused, Ended, Aborted. When in Running mode, you will see three animated dots |
|||
* Second field is current time (this time is acquired from NTP servers if Internet is present, or from configuration file - if not). |
|||
* Next two lines are program start date/time (month-day hours:minutes:seconds) and estimated program END time. ETA is calculated based on the program but will change during it's run - depending on conditions and configuration. |
|||
On the bottom there are two lines with current temperature and program settings. This screen changes slightly depending on program status (Running or not). From the left: |
|||
* Ct - Current temperature - this is temperature currently measured with your thermocouple |
|||
* St - Set temperature - this is temperature currently designated by program progress |
|||
* Amb - Ambient temperature - since all MAX chips have additional temperature sensor for thermocouple compensation, this is temperature of the MAX chip, so also the ambient temperature of your working area |
|||
* Stp - Step - This is current program step number / total number of steps. There is also indication if this is _r_unning phase or _d_well phase |
|||
* Ht - Heat percentage - this is value predicted by PID algorithm and indicated how long heating element should work in "PID_Window" size (default 5s). So if it's 20% - heating element will work 1s every 5th second. |
|||
* Cse - Case temperature - if you have additional MAX and thermocouple, this is it's value. By design this should be temperature of the kiln housing. |
