  Hi All,

  Not sure if anyone at all has even tried to make this project, or done any variant of this to add a TFT to their reflow oven?

  
  I've been distracted with my other hobbies (R/C aircraft!)... but I've finally gotten back to finishing up my EE lab, which brought me back to needing to use my oven again :)

  
  ewWin/embedded graphics continue to improve and get easier to do, my biggest complaint about this project in it's current status, is I'm a terrible graphics designer :)   My GUIs in their current shape are 'ok', but definitely not pretty or make you go 'wow'..

  I'm going to try and take another stab at this, using all the latest ewWin tools and see what I can do, plus I never did finish up the WiFi code, and implementing a 'wifi' firmware update feature.. really need to do that...

  Been a while since I worked on this!   Took some time off to work on some other things, so I'm finally coming back to this.  I did work on the WiFi setup code, etc a couple months ago, but just didn't have a chance to test it out and debug it up.

  Now that I'm coming back to this I'll finish up the WiFi code, and start looking at adding the capability to upgrade the software over the WiFi.  This may be quite tricky, so I'll see shortly if it's do-able or too insane to work out...

  I would like to eventually have a windows app that would allow a remote/RDP type capability, utilizing the WiFi, so you can essentially control your oven remotely over the wifi link, that would be awesome, and was a main part of the reason I wanted wifi in the first place.... 

  Maybe I can get lucky and find a developer that makes nice pretty windows GUIs to help out with this!  :)   I can make ok windows Apps, but I"m certainly not the best at it...

  Updated the software to version 1.2.0, enhancing the manual 'draw' function a bit to have the touch interrupts and draw functions run out of ram to speed up execution a little.  (not too much improvement there yet since the gui library STemWIN still runs out of flash).

  Also cleaned up some more bugs and cleaned up some menu item things, etc.

  Now that things seem more stable, will focus on the WiFi code, as I got sidetracked looking for and fixing any remaining bugs.  I would like to add the capability to flash the firmware over the wifi connection, so I"ll be looking into this as well while working on the WiFi stuff.

  Cleaned up this project page, and removed all redundant files that are already included in the main github repo (software link for this project)..

  software verson 1.1.0 will be posted tomorrow, contains a bunch of cleanup items, bug fixes, and the initial Wifi setup page, it's non-functional except for the enable/disable of the wifi module...

  (hopefully working WiFi setup will be in a 1.2.0 release in the next month or so )

  Added an initial 'USER GUIDE', it's far from being complete, but wanted to get something going so you all can get a better idea of what these menus look like, etc.

  
  I currently don't have any easy way to export the actual screen contents from the board to my debug PC, so I can show the screens without having to take pictures of them with my phone camera!  but for now it is good enough.... they do look much nicer on the screen then these camera phone pictures show :)

  Finally, I marked this project as COMPLETE!!

  
  I've finished and verified the latest 3.5 board is working, and the wifi add-on works, jumpers and header work for flashing, etc.  At this point there will be NO more hardware updates, the PCB design is complete.

  From this point moving forward, all updates will be SOFTWARE ONLY  :)

  I hope to have a v1.1.0 release within the next month or so, which will have initial wifi setup included, NO actual wifi usage with the oven, only the setup GUI that will allow you to configure and connect to your wifi, display the connection info, etc..

  Also in the coming weeks I will enhance and finalize the build instructions, installation instructions, etc (adding the info for the 7.0" resistor changes for the backlight power), and also start working on a USER'S GUIDE, which will have photos and explanations of all the menus, sub-menus, etc.

  Received the rev3.5 board from the fab, working on populating it now, will finish it up this weekend, and will verify that the added updates for the ESP32 wi-fi board work, and it can be flashed, comms, work, etc.

  
  Once I verify that the esp32 board works, and everything else works as it all should, I will then post the update and will get back to working on the wifi menus, etc..

  Alright, got the WiFi module added into the design, wired one up to my current board, and got it working, using a free GPIO pin to control the enable of the module, so we can have a checkbox in the settings GUI to enable/disable the entire module.

  
  Pretty sweet being able to do wifi and/or bluetooth, using a $3.80 part.

  First thing I'm going to get working for this, is to have the wifi settings page working with the module, so you can set your personal wifi settings, so the module can talk to your access point.. also allowing custom settings of IP or use DHCP.

  Wow, this is awesome:

  https://www.digikey.com/product-detail/en/ESP-WROOM-02/1904-1009-1-ND/8544304/?itemSeq=298085688

  
  

  Actually, probably going to use this one, as it has WI-FI & BLUETOOTH..

  https://www.digikey.com/product-detail/en/espressif-systems/ESP32-WROOM-32D/1904-1023-1-ND/9381732

  (and it's only $3.80, vs. $2.70 for the wi-fi only one)

  I wanted from early on to have a simple way to do Ethernet/Wi-fi on this thing, but didn't have enough pins on the STM32 to use their built-in lan interface, but with an all-in-one wifi module, I can add this on without having to do any TCP/IP crap, as it's all built into the module..

  
  I'll look at seeing how easy it is to add this on as a cable-up connection to the UART2 header already on the current PCB, as well as seeing if it's easy enough to add this footprint to the bottom side of the PCB and possibly do another PCB update..

  
  we shall see, but the reason I really want network of some kind, is at least to do:

  1) network monitoring of real-time reflow, etc

  2) Software upgrades over the network, so you don't need to open up the oven at all!

  And for $2.70!!!   that is insanely cheap..

  Working on two documents currently, to help installation and a user's guide... so hopefully this week I will add these two docs (here as well as in the github repo)

  1) Installation Guide

  2) Users Guide

  I will have pictures of all the GUIs/Menus, and some explanation of each, so you can better understand how it all works, and how to navigate around, etc..
