ESP Wordclock
Setup
Initial Setup
Install the firmware on the ESP: The ESP must be set into the bootloader mode, like this
The firmware can be downloaded with the following script:
cd os/ ./flash.sh ttyUSB0
Connect to the ESP via a terminal emulator like screen using a baud rate of 115200. Then format the filesystem and reboot the ESP with the following commands:
file.format() node.restart()
Then disconnect the serial terminal and copy the required files to the microcontroller:
./tools/initialDietFlash.sh /dev/ttyUSB0
Install the optional packages:
./tools/initialDietFlash.sh /dev/ttyUSB0 mqtt.lua ./tools/initialDietFlash.sh /dev/ttyUSB0 ds18b20.lua
Upgrade
Determine the IP address of your clock and execute the following script:
./tools/remoteFlash.sh IP-Address
Hardware Setup
Mandatory:
- GPIO2 LEDs
- GPIO0 Bootloader (at start)
- GPIO0 factory reset (long during operation) Optinal:
- ADC VT93N2, 48k light resistor
- GPIO4 DS18B20 Temperatur sensor
