Dstike V1 watch

[josephchrzempiec]

Hello i have a Dstike watch i got from ebay https://www.ebay.com/itm/383846316645. It works and all but its very hard to program for me that is. My skills are in hardware not really software but I'm trying. The watch only contains a esp8266mod and a 1.3" oled looks like it's using a SH1106 library. I have look for one online and found this one https://github.com/wonho-maker/Adafruit_SH1106. It looks like it was based off of adafruit library. But i can not confirm it.

i have tired it and i can not get it to work. I went into the Issues area and posted a problem for a delay problem. I found out the delay is for AVR not a 32bit micro processor. I can not find something that works for the Esp8266 and this display. i know this is not a dafruit product. Can someone please help me?

Hello i still can not figure this out. And why i do not get nothing on the screen. I'm posting a code below for this.

Code: Select all

#include <TimeLib.h>
#include <Wire.h>  
#include "SH1106Wire.h"

SH1106Wire display(0x3c, D7, D5);  // ADDRESS, SDA, SCL
//SSD1306Wire  display(0x3c, D7, D5);
// Include the UI lib
#include "OLEDDisplayUi.h"

// Include custom images
#include "images.h"

// Use the corresponding display class:

// Initialize the OLED display using SPI
// D5 -> CLK
// D7 -> MOSI (DOUT)
// D0 -> RES
// D2 -> DC
// D8 -> CS
// SSD1306Spi        display(D0, D2, D8);
// or
// SH1106Spi         display(D0, D2);

// Initialize the OLED display using brzo_i2c
// D3 -> SDA
// D5 -> SCL
// SSD1306Brzo display(0x3c, D3, D5);
// or
// SH1106Brzo  display(0x3c, D3, D5);

// Initialize the OLED display using Wire library
//
//SSD1306Wire  display(0x3c, D3, D5);
// SH1106 display(0x3c, D3, D5);

OLEDDisplayUi ui ( &display );

int screenW = 128;
int screenH = 64;
int clockCenterX = screenW/2;
int clockCenterY = ((screenH-16)/2)+16;   // top yellow part is 16 px height
int clockRadius = 23;

// utility function for digital clock display: prints leading 0
String twoDigits(int digits){
  if(digits < 10) {
    String i = '0'+String(digits);
    return i;
  }
  else {
    return String(digits);
  }
}

void clockOverlay(OLEDDisplay *display, OLEDDisplayUiState* state) {

}

void analogClockFrame(OLEDDisplay *display, OLEDDisplayUiState* state, int16_t x, int16_t y) {
//  ui.disableIndicator();

  // Draw the clock face
//  display->drawCircle(clockCenterX + x, clockCenterY + y, clockRadius);
  display->drawCircle(clockCenterX + x, clockCenterY + y, 2);
  //
  //hour ticks
  for( int z=0; z < 360;z= z + 30 ){
  //Begin at 0° and stop at 360°
    float angle = z ;
    angle = ( angle / 57.29577951 ) ; //Convert degrees to radians
    int x2 = ( clockCenterX + ( sin(angle) * clockRadius ) );
    int y2 = ( clockCenterY - ( cos(angle) * clockRadius ) );
    int x3 = ( clockCenterX + ( sin(angle) * ( clockRadius - ( clockRadius / 8 ) ) ) );
    int y3 = ( clockCenterY - ( cos(angle) * ( clockRadius - ( clockRadius / 8 ) ) ) );
    display->drawLine( x2 + x , y2 + y , x3 + x , y3 + y);
  }

  // display second hand
  float angle = second() * 6 ;
  angle = ( angle / 57.29577951 ) ; //Convert degrees to radians
  int x3 = ( clockCenterX + ( sin(angle) * ( clockRadius - ( clockRadius / 5 ) ) ) );
  int y3 = ( clockCenterY - ( cos(angle) * ( clockRadius - ( clockRadius / 5 ) ) ) );
  display->drawLine( clockCenterX + x , clockCenterY + y , x3 + x , y3 + y);
  //
  // display minute hand
  angle = minute() * 6 ;
  angle = ( angle / 57.29577951 ) ; //Convert degrees to radians
  x3 = ( clockCenterX + ( sin(angle) * ( clockRadius - ( clockRadius / 4 ) ) ) );
  y3 = ( clockCenterY - ( cos(angle) * ( clockRadius - ( clockRadius / 4 ) ) ) );
  display->drawLine( clockCenterX + x , clockCenterY + y , x3 + x , y3 + y);
  //
  // display hour hand
  angle = hour() * 30 + int( ( minute() / 12 ) * 6 )   ;
  angle = ( angle / 57.29577951 ) ; //Convert degrees to radians
  x3 = ( clockCenterX + ( sin(angle) * ( clockRadius - ( clockRadius / 2 ) ) ) );
  y3 = ( clockCenterY - ( cos(angle) * ( clockRadius - ( clockRadius / 2 ) ) ) );
  display->drawLine( clockCenterX + x , clockCenterY + y , x3 + x , y3 + y);
}

void digitalClockFrame(OLEDDisplay *display, OLEDDisplayUiState* state, int16_t x, int16_t y) {
  String timenow = String(hour())+":"+twoDigits(minute())+":"+twoDigits(second());
  display->setTextAlignment(TEXT_ALIGN_CENTER);
  display->setFont(ArialMT_Plain_24);
  display->drawString(clockCenterX + x , clockCenterY + y, timenow );
}

// This array keeps function pointers to all frames
// frames are the single views that slide in
FrameCallback frames[] = { analogClockFrame, digitalClockFrame };

// how many frames are there?
int frameCount = 2;

// Overlays are statically drawn on top of a frame eg. a clock
OverlayCallback overlays[] = { clockOverlay };
int overlaysCount = 1;

void setup() {
  Serial.begin(9600);
  Serial.println();

	// The ESP is capable of rendering 60fps in 80Mhz mode
	// but that won't give you much time for anything else
	// run it in 160Mhz mode or just set it to 30 fps
  ui.setTargetFPS(60);

	// Customize the active and inactive symbol
  ui.setActiveSymbol(activeSymbol);
  ui.setInactiveSymbol(inactiveSymbol);

  // You can change this to
  // TOP, LEFT, BOTTOM, RIGHT
  ui.setIndicatorPosition(TOP);

  // Defines where the first frame is located in the bar.
  ui.setIndicatorDirection(LEFT_RIGHT);

  // You can change the transition that is used
  // SLIDE_LEFT, SLIDE_RIGHT, SLIDE_UP, SLIDE_DOWN
  ui.setFrameAnimation(SLIDE_LEFT);

  // Add frames
  ui.setFrames(frames, frameCount);

  // Add overlays
  ui.setOverlays(overlays, overlaysCount);

  // Initialising the UI will init the display too.
  ui.init();

  display.flipScreenVertically();

  unsigned long secsSinceStart = millis();
  // Unix time starts on Jan 1 1970. In seconds, that's 2208988800:
  const unsigned long seventyYears = 2208988800UL;
  // subtract seventy years:
  unsigned long epoch = secsSinceStart - seventyYears * SECS_PER_HOUR;
  setTime(epoch);

}


void loop() {
  int remainingTimeBudget = ui.update();

  if (remainingTimeBudget > 0) {
    // You can do some work here
    // Don't do stuff if you are below your
    // time budget.
    delay(remainingTimeBudget);

  }


}

I'm not sure what else i can do. I really need help.

Joseph,

We don't sell this watch or this exact hardware, but there are some Tindie sites that link to options for programming the older esp8266 Dstrike devices.


https://github.com/SpacehuhnTech/esp8266_deauther

I went with the LilyGo which is ESP32 based supports micropython and has some solid docs. The newer Dstrike models (ESP32) have similar support.
