Update Readme with hardware hints

[popy2k14]

Upon building 3x clocks i had several hardware "issues" to solve to get it working.

First is the SH1107 Display:
I have got one with switchable SPI/I2C and todo the following to get it working.
Here is a link with some infos: https://simple-circuit.com/interfacing-arduino-sh1107-oled-display-i2c-mode/

• Solder Resistor from R3 to R4 to activate IIC
• Solder DS & CS to GND
• Solder RES to VCC (3,3V)

And some pictures:

• This device had an neopixel connected with an resistor to GPIO48, which is SDA for the display. To get it working i had to remove it.
• Also there is an not connected solder jumper which had to be connected to get +5V onto the +5Vin pin (for the amplifier).

Here is a picture:

To use the full 16MB flash i had to add this to my yaml.

And download the and rename this file and place it into the esphome folder: https://github.com/espressif/arduino-esp32/blob/f6e12eb7e900fd6484e186b4b681f5b9504d2e85/tools/partitions/default_16MB.csv

This font is missing in the fonts folder, please upload it.
In the meantime, i got it from here: https://cdnjs.com/libraries/MaterialDesign-Webfont

Can you please add all this to the readme or wiki?

thx

Nice, i have this display to and never found a way to get it to work. Will add it.

I have this one also, and it did also not work. Later I discovered that the usage of 5v is not needed for the MAX98357a, so your suggested alteration for the 5v is not really needed. As for the soldering for GPIO48, i think another GPIO can also be used. Will check this all out, but that will take a while before I can give feedback on that.

So, this is arduino based, and the current iteration of SOAS is arduino based but due to https://community.home-assistant.io/t/soas-full-featured-alarm-clock-with-home-assistant-integration/847108/22?u=ensconce I must switch to the esp-idf framework. Does this still apply?

I will upload the font a.s.ap.

thx

Take your time

ESP32-S3-N16R8 with 16MB Flash & 8 MB PRAM:
I don't know if this is needed with esp-idf framework.
It also ran stable for me without this change.
Just found this on googling other issues with board, so I added it for now on my devices.
