MQTT-ed my Christmass tree lights using TFT32 powered touch control. It sends Tasamota flashed Sonoff S20 commands over MQTT using #Arduino #littlevgl #ESP32 #TFT source code: https://github.com/mharizanov/TFT32/tree/master/examples/gui/mqtt_controller Buy TFT32 https://harizanov.com/product/tft32/ Merry Christmas!
Working on TFT32 product wiki https://harizanov.com/wiki/wiki-home/tft32/ , I will include Arduino example code soon #IoT #ESP32
Just finished setting up a small e-shop for the TFT32 project on my blog grab one from here (I have only a few to sell): https://harizanov.com/product/tft32/
New product: TFT32 https://harizanov.com/product/tft32/
20 pcs #ESP32 TFT project ready 🙂
Even better idea: switch to cURL for #ESP32 OTA, that will enable OTA over gzip compressed http(s) sources, (s)ftp, ssh #IoT
Idea: compress OTA images to reduce OTA time, similar to UART flash on #ESP32
Added GUI to monitor OTA updates to #ESP32 TFT project
Found this today, now #brexit makes sense. Agree?
Testing 3D printed enclosure for #ESP32 TFT project #IoT, looks and feels much more finished now 🙂
Stocking tens of TFTs with touch 🙂
Experimenting with SQLite DB running on #ESP32, the database itself on a SPIFFS partition. I have some pretty interesting use cases in mind.. https://github.com/siara-cc/esp-idf #IoT
Moving #ESP32 graphical GUI resources to dedicated shared R/O SPIFFS partition to reduce main code partition sizes. This also decouples the code from GUI, allows easier branding/styling of the final product, but complicates OTA updates..
TO-DO: research project feasibility: swap the RFM69 for a LoRaWAN on my #ESP32 TFT project and use it as SIM-less urban car telemetry/location tracker
Planning to do a tach talk on topic "Developing connected thermostats" sometime in February, details will follow. http://dev.bg
Three-point resistive touch calibration GUI is now complete #ESP32 #IoT
20 PCBs for revision 6 of my #ESP32 #TFT project arrived. I think that it is complete now, need to stop shelling money on perfecting it at least 🙂 Now awaiting components delivery to run a small batch SMD assembly. I will have few spares to sell late December
I originally thought resistive touchscreen calibration is a mere interpolation of measured and actual coordinates, little did I know..Just finished implementing high precision three-point resistive touchscreen calibration functionality using TI's guideline http://www.ti.com/lit/an/slyt277/slyt277.pdf
Working on native #ESP32 OTA over MQTT (TLS), the use case is that I have devices behind restrictive firewalls that block outgoing HTTP(S) connections but allow MQTT over TLS
#ESP32 GUI translation proof of concept works well. Thanks for the translation tips! #IoT
Working on GUI multilanguage support using Google translation. Hopefully no 'lost in the translation' situations 🙂 . I speak no German, so need help: how do you abbreviate 'Einstellungen', too long to leave as is..
Running around the house and cars to adjust dumb clocks due to the DST change. Happy that this archaic madness ends next year in the EU..
Toying with some funky touch GUI icons
Experimenting with thermostat touch GUI with iPhone style setpoint selector #ESP32 #IoT
Porting various SPI/I2C peripherals drivers to #esp-idf #RTOS has been a major #PITA, but I'm almost done… phew #ESP32 #RFM69
The 3D-printable enclosure for my #ESP32 TFT display project is taking shape, but still WIP.. #IoT
Burned a MCU due to ESD the other day, will use antistatic gloves from now on 🙂
@spectrenoir06 no, my own version
Touch driver for the #ESP32 GUI implemented, looks and feels lovely
Working on a 3D-printable enclosure for my #ESP32 TFT #IoT project
#ESP32 driven touch workins well :).. and I am bad at drawing
Touch display arrived today. Did some SMD soldering by hand, all works well at first glance. Tons of coding ahead.. #ESP32 #TFT #IoT #RFM69
