Hello, I tried to use the larger eyes default_lager from https://github.com/PaulStoffregen/ST7735_t3/blob/master/examples/uncannyEyes_async_st7789_240x240/graphics/default_large.h with an esp32c3 board (seeeduino xiao), but whe I use this file all I got was a blank display. It compiled without...

That's it! Forgot about this line. Thank's for the help! lab

Hi, I am using this code for toggeling debugging on/off: #define DEB_ON #ifdef DEB_ON #define DEBUG_PRINT(str) Serial.print(str) #define DEBUG_PRINTLN(str) Serial.println(str) #else #define DEBUG_PRINT(str) #define DEBUG_PRINTLN(str) #endif Unfortunately I get a compiling error...

I tried to change the baud rate - this didn't work at all. I got no messages from the esp at all. So I will give the #3 a try next. Greetings, Kai

Thanks for your answer and help! I will try your suggestions asap! Would it help to move the serial communication part into the setup? I only need to check the time at startup... Greetings, Kai

Hi, I am trying to get a NNTP time sync via esp8266 to my Teensy LC, following this guide: https://www.geekstips.com/arduino-time-sync-ntp-server-esp8266-udp/ for a word clock project. The esp part works like a charm, putting the unix time code out over serial as message like "UNX1509820636"...

Output is as shown on first post (last section). Will try yout ideas and report if it helped. Thanks for your help!

Ok, this is what I did yesterday: - changed the baud rate to 57600 and after that to 115200: no effect - I already connected the esp8266 to an ftdi adapter and tested it alone: in every single case the serial command was send. Today I changed the serial input pin on the teensy lc from Serial1...

Another observation: I put both serial routines into the code. When the serial1 function stops to work, serial (via terminal) stil works.

Ok, now I edited the post with the complete code... I also tried using the serial monitor as you suggested. It worked... So I have a part on the teensy working alone and a part on the esp12 working alone. But together they do not work :-(

Hi defragster, thanks for your ideas. I will try your suggestions. I don't think the problem is on the esp side because I have a led light up after serial data so I can see the part is executed and I tested the esp part by using it solitary and watching the commands on the serial monitor. Do...

Hi, I have a projekt where I want a esp8266 to serve a web page with some buttons. Click on these buttons sends serial data to a teensy lc and the teensy should evaluate the data. Generally it works but after a few cicles the teensy stops receiving the commands. I know that there are send...

The Reichelt one is only 5 € - but I neber managed to get DCF to work. I finally switches to a RTC clock module and set the time by hand ...

I commented out the Serial1.clear() and the serialCommand="". Didn't solve the problem. I am not sure, what you mean by arduino code base. I am using the arduino ide to program the esp8266. This is the code running: /* * * M O O D L I G H T WebControl * * Steuerung der...

When I first had this problem, the serial speed was 115200 on both sides. I changed it to 19200 because I thought it could be too fast ... I used a mix of different sources for my esp code - will post it later.

Hi Frank B, I changed sizeOf(serialCommand) to serialCommand.legth() - that should fit better... Thanks for the hint. Unfortunately it doesn't solve the problem. The serialComplete ist not used at the moment - but this should not be a problem, right? With the last two lines I tried to reset...

Thanks to all the feedback I made a lot of progress and i am very happy how far I got. But now I am stuck again. I got my sketch to work - mostly ... I re-programmed my esp8266 to work as a stand alone webserver: works great! I got him receiving signals from the web pag when a button is...

Thanks @wozzy and @defragster for the tipps! I already figured out I have to change my whole approach so the tipp from @defragster totaly comes at the right moment!. As I want to build a rgb matrix display that is controled via web interface I need the Teensy to control the matrix. To have a...

Hi. I am fairly new to Arduino/Teensy programming so please forgive if that is stupid question. I am using a Teensy LC connected to an esp8266 201 to serve a webpage. The html code is written to a string variable and send to the esp8266 via AT+CIPSEND. I found that the page is not served if...

Thanks, Xenoamor & mlu! Yes, that was the problem. It is compiling noow and I see data coming in. I still get no reasonable time information from the sensor. :-( Does anyone has used this sensor successfully before?

Hi, I am trying to build a word clock with a Teensy LC. Everything is working and I could use a rtc time moduel DS3231 with success. Now I am trying to get the current time from a dcf77 module (this one: http://www.pollin.de/shop/dt/NTQ5OTgxOTk- ) and the standard dcf77 library. But I get a...
