ESP8266 Internet Clock, Weather Station and Information Display

Another quick project. Quick - because I had almost everything ready. The only thing I had to learn is JSON and HTML parsing from the internet sources.
Features:
- my old ESP-01 module which I finally found good application for (now you can buy better cheap ESPs)
- 6x LEDMatrix module with MAX7219 driver
- supplied directly from USB port thanks to convenient 3.3V voltage regulator with USB plug
- all data are synchronized every 7-8 minutes
- time and date are taken from google.com
- weather informations are grabbed from openweather.org JSON api
- currency rates are grabbed from HTML page
- in the future also other news and infos grabbing can be possible
- no hardware RTC clock is necessary
- no temperature, humidity or pressure sensor
Connections are pretty trivial:
- DataIn to GPIO2
- Load/CS to GPIO1
- Clk to GPIO0
- CH_PD connect to VCC via pullup resistor 10kohm
- 100nF capacitor soldered between VCC and GND
- both resistor and capacitor are soldered directly to ESP8266 module
- 3.3V is taken from voltage regulator module with USB plug, connect it to free VCC/GND pins in last LED Matrix
- soldered extra VCC line between last and first matrix module (to avoid voltage drop)

Most cameras have issues when it comes to recording LED's. I think the clock looks absolutely fine. I would slow down the scroll a touch but other than that, I say it is nice.

@HariWiguna 8 лет назад

That's a cool project! Looks great even with the camera artifacts! Well done! BTW, I discovered that my cellphone camera syncs with fluorescent light and that seem to interfere with multiplexed displays. Incandescent or natural daylight seems to work better.

@cbm80amiga 8 лет назад

Thanks. I will have to test different settings in my camera in the future. Probably some sort of filter would also help because recorded LEDs are not red as in reality.

Another great project. It seems that everyday I stumble across another of you awesome projects. I am currently working on a couple more recent ones using Nokia 5110/HX1230. Really like the LED ones like this and will "copy" it.....thanks. Do you have or would you consider a project like this that has wireless temperature using HC-12 or NRF24L01 or similar. Huge fan of all things on your channel! Thank you for making it possible for me and others to make projects like this that we would not be able to do otherwise. For me it's not just copying your work, but I am able to learn some stuff and in some cases add or change things that i want.

@pfeerick 8 лет назад

Hm, the extra pull-up resistor probably explains the two ESP-01s that commit suicide due to thermal runaway. I neglected to factor that the module didn't have them on itself! Number 3 has been running perfectly - but it also hasn't been unplugged or reset, so hasn't had a chance to go stupid on me! Another great project!

@cbm80amiga 8 лет назад

Thanks. Regarding pullup resistor - I've seen many people just connect it directly to VCC which is not correct.

@pfeerick 8 лет назад

lol... indeed... The ESP8266s are nice chips, but it's unfortunate some of the pins are fussy about their high or low states on powerup. Would have been nice if the module developers had taken the time to put the couple of SMD parts on that would have made them so much more reliable! :-O

Sorry for being a bit puzzled here, but how are 7219 outputs connected? It is an 8x48 matrix and the 7219 outputs are 8x8. I was just wondering how the matrix is connected (and what kind of displays are used?) Thanks Mike

I used popular and cheap Chinese 8x8 LED matrix modules. You can connect them to have wider display. Here there are 6 modules.

Hi friend! Great project! I have a few questions: 1) The code is working but my nodeMCU gets "Connecting and getting data" from time to time. 2) What this String means: weatherLang = "xxxxx = xx"; 3) I have 8 matrix modules: how can I centralize the text (Hours) in these 8 modules? Thank you very much

@cbm80amiga 6 лет назад

1. because it looses internet/WiFi or there is other instability. Try to add high value capacitor at ESP8266 power rail 2. It just sets language for weather messages 3. Extend buffer memory for scr[] / NUM_MAX and change values in digPos[] array

Could you explain where you find GPIO1 pin on ESP-01? In all specifications I see only GPIO0, GPIO2, RX, TX, GND, VCC, RST, CH_PD. Also, how do you think, could this work with Max72xxPanel lib?

@cbm80amiga 7 лет назад

GPIO1=TX and GPIO3=RX. Look at the source code - it is mentioned there. If the lib you are mentioning doesn't use hw SPI it should work using bitbanging like in my code.

You can use 0, 90 or 270 value for rotate, but matrixes I know are rotated 90 degrees or are not rotated at all.

please explain the code below: float UTCOFFSET = 7; // what does it mean Long localEpoc = 0; //what does it mean Long localMillisAtUpdate = 0; // what does it mean I come from Vietnam, the installation of how that value.

@cbm80amiga 7 лет назад

local* variables are local and they keep current epoc and start time when it was updated from google server. utcoffset keeps offset in float type so you can define for example +9.5h - it just adds offset to utc time returned from the server. In case of Poland it is defined as 1h (winter time). In case of Vietnam just use 7. You don't have summer time so it helps a bit.

@mrwizworks 7 лет назад

can you please help me? i got your code to run but the characters are 90 degress counter clockwise. how to change?

@cbm80amiga 7 лет назад

There is a patch where you have to define ROTATE 90, but better use newer version of this project - link in the description.

@mrwizworks 7 лет назад

Ok found the patch - thank you. The other problem I noticed is that when I set the UTC offset (-5) the date is incorrect late in the day. For example, right now it is 23:39 (friday) but though the time is correct, the date is wrong. Seems the date is a few hours ahead because it's saying saturday feb 25th when it's still Friday night, the 24th. Can you tell me what to do to correct this offset issue?

Good afternoon! Tell me the details of your code, that is?? 12.USB to Serial programming 13.ESP-1 from rear, FF to GND, RR to GND before upload 14.Gr FF -- Bl 15.Wh -- RR Vi FF? RR? Gr? Bl? Wh? Vi? Thank you!

@cbm80amiga 7 лет назад

FF is GPIO0 - during flashing ESP it must be LOW, RR is RESET and should be LOW just before flashing. Gr? Bl? Wh? Vi? are just colors of my wires :) ESP-01 should be connected as descibed in the code GPIO 2 - DataIn GPIO 1 - LOAD/CS GPIO 0 - CLK
