<\/p>\n\n\n\n
With the initial prototyping of my IoT Controller now completed, and software performing as expected, I have started with the development of an add-on shield. The base device offers 2 built-in relays, and access to another 6 IO Ports on the PCF8574, as well as all the GPIO on the ESP-12E. This is all good and well and suits my initial purposes well, but
I do however now see a need to add more sensors to the device, as well as find an elegant way to power it directly from mains power, while not having lots of wires going anywhere.<\/p>\n\n\n\n
So the next steps will be:
Design an add-on-shield to provide me with the following:
– Analog inputs.
\u00a0The ESP-12E has only one, and that will be very limiting in some situations.
-Digital Inputs and Outputs
\u00a0While there are still unused GPIO ports on the existing board, native to the ESP-12E,
\u00a0having the ability to connect additional devices and sensors will definitely be a good
\u00a0option to have in future.
-Some sort of Display
\u00a0Small OLED I2C displays are cheap and easy to use. I can also go full colour with an SPI
\u00a0display…
From here on, I have to decide on how and what.
I can go the discreet chip route, by using dedicated I2C chips that provide all these functions, or I can add a secondary micro-controller to the shield, which would provide more flexibility, but can also add complexity to the final design…<\/p>\n\n\n\n
Please follow along and join me on the next part of this design journey. I can not promise
anything yet, but I do guarantee that it will be exciting…<\/p>\n","protected":false},"excerpt":{"rendered":"
