ESP32-C3 Pocuter word watch

Home
A small watch that displays the time in words in Dutch, English, French and German or digital on a tiny display.
The watch is able to receive time via NTP from the internet.
Settings can be controlled via a webpage, PC and Bluetooth LE.
If the watch is used stand-alone, without connections, it can be controlled with buttons.

Latest versions and updates on Github

The watch is built in a Pocuter One equipped with  a ESP32-C3 chip and SSD1131 OLED display built by www.pocuter.com
The software is written in the Arduino IDE 1.8.19 and IDE 2.0.0.

The software contains coding to use the:
1 Pocuter One with 96x64 pixels OLED colour display
2 BLE nRF UART connection with an option to send strings longer than 20 bytes
3 Get time zone corrected time with daylight savings from a NTP server via WIFI
4 RGB LED
5 RTC for time keeping when off line
6 Storage of the settings on SD-card.
7 Or storage of the settings in the ESP32-C3 SPIFSS Flash memory
8 Menu driven control of preferences with serial monitor, BLE and WIFI-html page
9 Buttons
10 Four languages to display time

Het was tien over tien 10:13:00 Il est dix heures et quart 10:14:00 Il est dix heures et quart 10:15:00 Het is kwart over tien 10:16:00 Es war viertel nach zehn 10:17:00 It was quarter past ten 10:18:00 Il est dix heures vingt 10:19:00 Es ist zehn vor halb elf 10:20:00 Het is tien voor half elf 10:21:00 It was twenty past ten 10:22:00 It was twenty past ten 10:23:00 Het is vijf voor half elf 10:24:00 Es ist funf vor halb elf 10:25:00 It is twenty five past ten 10:26:00 Es war funf vor halb elf 10:27:00

Installations 
There are two versions of this application.
One version has the option to store preferences on a SD-card. The a fast screen access is also possible.
In this mode the screen updates much faster.
The other version has a slower screen access. No SD card is needed because the settings are stored in the SPIFFS memory of the ESP32-C3.
There are to ino files and .bin version to upload available. The filename of the fast screen version end with FS.
If you compile the application your self locate this line in the top of the program and remove the // for fast screen access and the use of an SD card.
Compile and upload it into the pocuter

//#define FASTSCREEN     // Use SD for storage instead of SPIFFS. ....

When a SD card is used:
Insert a FAT formatted SD-card. Settings will be saved on it in both version.
In 2022 the SD-card reader does not read all SD-cards properly. Use an old slow (eg 80MB/s) 16GB or less card.
If the SD-card is omitted the data will be stored in the Pocuter when the slow screen access version is used. With the FS-version data will be lost when the
If the clock is connected to the internet it will seek contact with a time server.
The time zone is set to UTC+1 Amsterdam but can be changed in the menu.
To connect to a WIFI network a SSID and password must be entered.
There are a few methods:
- Connect the Pocuter with a serial cable to a PC and use a serial terminal. I use the Arduino IDE or Termite as serial terminal.

Sending the I for information will display the menu followed with the actual settings of several preferences

Control and settings of the clock

If there is no WIFI connection time and digital or word clock mode can be set with the three buttons.
Check at the bottom of the menu if WIFI is OFF.
The clock will start much quicker because it will not try to connect.

Top Left: + 1 hour
Right bottom: + 1 minute
Top Right: Toggle between word or digital display

As mentioned before the clock can be controlled with the WIFI webpage or BLE UART terminal app.
When the clock is connected to WIFI the ip-address is displayed in the Digital display (Press Top right button to select it).
Enter this ip-address numbers and dots (for example: 192.168.178.77) in the browser of your mobile or PC where you type your internet addresses (URL).
or search items.
Or
Open the BLE terminal app. Look for the WordClock to connect to and connect.
BLE connection can be made with my app BLE Serial pro on the app store for Apple IOS devices.
For Android  nRF UART terminal program and Serial Bluetooth terminal from Kai Morich
Unfortunately this Android apps can not read strings longer than 20 characters.
If you see a garbled menu enter and send the character 'Z' to select the slower transmission mode

Settings are set by entering the first character of a command following by parameters if necessary.
For example: To set the colours of the fonts in the display to white enter: Q2
To shown random all four languages every minute send L4.

Set the time by entering T130245. (130245 will also work)

Turn off WIFI by sending a W.

Reset the Pocuter with the letter @.

Reset to default setting by send R.

In the BLE connection the SSID and password will be shown.

Detailed description

With the menu many preferences can be set. These preferences are stored on a SD-card or in the ESP32-C3 storage space.
 
Enter the first character in the menu of the item to be changed followed with the parameter.
There is no difference between upper or lower case. Both are OK.
Between the ( )

A SSID B Password C BLE beacon name
Change the name of the SSID of the router to be connected to.
aFRITZ!BoxEd or AFRITZ!BoxEd
Then enter the password. For example: BSecret_pass
Restart the Pocuter by sending @
Entering a single 'b' will show the used password. This Easter egg can can used to check if a valid password was entered

D Set Date  and T Set Time
If you are not connected to WIFI you have to set the time and date by hand
For example enter: D06112022 to set the date to 6 November 2022.

Enter for example T132145 (or 132145 , or t132145)  to set the time to 45 seconds and 21 minute past one o'clock.

E Set Timezone E<-02>2 or E<+01>-1
At the bottom of this page you can find the time zones used in 2022.
It is a rather complicated string and it is therefore wise to copy it.
Let's pick one if you happen to live here: Antarctica/Troll,"<+00>0<+02>-2,M3.5.0/1,M10.5.0/3"
Copy the string between the " "'s and send it with starting with an 'E' or 'e' in front.
E<+00>0<+02>-2,M3.5.0/1,M10.5.0/3

Time zones and daylight savings should be ended and replaced by one universal date and time for the while planet cq universe.
But that is my opinion.

Make own colour of: (Hex RRGGBB)
F Font G Dimmed font H Bkgnd
You can set the colours of the highlighted and dimmed characters and  the back ground
The time is shown with the colour defined with Font when Display choice Q3 or Q4 is chosen and the rest of the not highlighted characters are coloured with the setting in Dimmed font.
The format to be entered is hexadecimal. 0123456789ABCDEF are the character that can be used.
The command is 2 digits for Red followed with  two for Green and ending with two digits for Blue.
To colour the characters intense red enter FF0000 prefixed with the letter F, G or H.
To set the background to intense blue enter: H0000FF
To set the dimmed character to dark gray enter for example: G191919. You get gray if red, green and blue has the same intensity.

I To print this Info menu
Print the menu to Bluetooth and the serial monitor connected with an USB-cable

L L0 = NL, L1 = UK, L2 = DE, L3 = FR, L4 = Wheel
You can choose between four languages to display or show them randomly every minute.

N Display off between Nhhhh (N2208)
With N2208 the display will be turned off between 22:00 and 8:00.

O Display toggle On/Off
O toggle the display off and on.

Q Display colour choice (Q0-6)
Q0 Yellow Q1 hourly Q2 White Q3 All Own Q4 Own Q5 Wheel Q6 Digital display

Q0 will show the time with yellow words.
Q1 will show every hour another colour.
Q2 shows all the texts white.
Q3 and Q4 uses you own defined colours.
Q5 will follow rainbow colours every minute.
Q6 is the digital display with the IP-address and date until seconds are 00.
You can also press the top right button.
The selected choice is displayed at the bottom of the menu.
Send an 'I' to display the latest's settings

R Reset settings
R will set all preferences to default settings, it also clears the SSID and password.

@ = Restart Pocuter
@ will restart the Pocuter. This is handy when the SSID, et cetera are changed and the program must be restarted.

W=WIFI, X=NTP, Y=BLE, Z=Use SD
Toggle WIFI, NTP on and off.
Enter the character will toggle it on or off. A the bottom of the menu the stated is printed.

Z Fast BLE
The BLE UART protocol sends default packets of 20 bytes. Between every packet there is a delay of 50 msec
The IOS BLEserial app, and maybe others too, is able to receive packets of 80 bytes or more before characters are missed and
Option Z toggles between the long and short packages. 

Because not all Pocuter functionalities in the Pocuter library were described or could be found by me at the moment of writing this program several standard ESP32-C3 DEV functionality was used.
In this software version only the Pocuter Button and OLED screen functionality were used

Settings are stored on the SD-card or if no SD is present in the SPIFFS space from the ESP32-C3

The following libraries are used.

#include <Pocuter.h>
#include <NimBLEDevice.h>      // For BLE communication  https://github.com/h2zero/NimBLE-Arduino
#include <ESPNtpClient.h>      // https://github.com/gmag11/ESPNtpClient
#include <WiFi.h>              // Used for NTP tme and web page
#include <AsyncTCP.h>          // Used for webpage   https://github.com/me-no-dev/ESPAsyncWebServer
#include <ESPAsyncWebServer.h> // Used for webpage   https://github.com/me-no-dev/ESPAsyncWebServer
#include <Preferences.h>       // Used for SPIFFS file system

To compile the software some standard setting must be changed.
First copy the Pocuter libraries in the libraries folder where your sketches are saved.
In my case copy from here: c:\Program Files (x86)\Arduino\libraries\Pocuter\ to here c:\Users\ednie\Documents\Files\Arduino\libraries\Pocuter\
Now we do not change the original Pocuter library and we keep all the non-standard Arduino libraries in one place.

To be able to compile the ESP32 Arduino boards must be installed and the ESP32 C3 DEV board selected.
Maybe the latest Pocuter board also compiles fine and you can use Fast screen mode with SPIFFS storage.

Global variables use 44044 bytes (13%) of dynamic memory, leaving 283636 bytes for local variables. Maximum is 327680 bytes. 

Some lessons learned:

• Use pocuter->begin(PocuterDisplay::BUFFER_MODE_DOUBLE_BUFFER);  for a fast screen display
• To print to the Serial monitor and receive input from it
  Use USBSerial instead of Serial.  Serial.print is USBSerial.print
• Saving of a file in ESP32 memory with EEPROM, Preferences libraries in the Pocuter ESP32 memory does not work in combination with the fast display mode.
  ( pocuter->begin(PocuterDisplay::BUFFER_MODE_DOUBLE_BUFFER);  )
  Use: pocuter->begin();
  

If the Pocuter hangs or rests constantly uploads are not possible anymore you can place the pocuter in upload mode
Press the button near the pins, keep it down, press and release the reset button near the USB-port and release the button near the pins.
It is a little fiddling with the small buttons but it worked for me always to upload again after dozens of crashes due to bugs and programming errors
