board profiles: pre-configured pin layouts about ems-esp32

[bbqkees]

Yes board profiles are not exclusively tied to BBQKees boards. It's for all common configurations.

Was discussing this with BBQKees today. We decided to call it a Board Profile, which is basically a drop-down list in the Web settings that sets the default values for GPIOs (Rx, Tx, Dallas, Ethernet, LED invert) that match his gateway boards and auto-fill in the settings on the page.

Also a build option -DBOARD_PROFILE= that sets the default values in the firmware so Kees can upload onto the board and it'll work out of the box.

sounds good. Please support also the Wemos MINI D1 ESP32, which works out of the box right now.

Made the first steps in the web. Next is to have EMS-ESP send a list of valid profiles to the Web UI with the GPIO configurations.

Still To Do:

• Modify the console command 'set ethernet ' to 'set board_profile '
• Remove the ethernet profile. This is now determined by the board profile, and no longer configurable
• Detect a -DBOARD_PROFILE and if the filesystem is empty, create based on the profile. This is so pre-configured pin settings can be uploaded in the firmware
• EMS-ESP stores the profiles in the C++ code and sends GPIO pins to the Web on selection (only rx, tx, led, button, dallas)
• create a GPIO validator for the web that excludes some GPIO pins like 1, 6-11, 12, 14 & 15. But allowing 0
• test for valid GPIO in code on startup to prevent crashes

some settings which I'll use for reference:

Wemos MINI D1-32 (rx=23, tx=5, dallas=18, led=2, pbutton=0)
Lolin D32 (rx=17, tx=16, dallas=14, led=5, pbutton=0)
BBQKees Gateway S32 (rx=23, tx=5, dallas=4, led=2, pbutton=0)
BBQKees Gateway E32 (rx=5, tx=17, dallas=4, led=2, pbutton=33, phy_addr=1, power=16, mdc=23, mdio=18, clockmode=0_IN)
Olimex ESP32-EVB-EA (rx=5, tx=17, dallas=4, led=2, pbutton=33, phy_addr=0, power=-1, mdc=23, mdio=18, clockmode=0_IN)

still to add the ethernet and compile build flags.

all done now and ready to test
