Testing 3D printed enclosure for #ESP32 TFT project #IoT, looks and feels much more finished now π

Stocking tens of TFTs with touch π

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 π 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 π . 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 π
@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
Lost some self-confidence after seeing my @SparkToro's fake followers audit say 36.2% of my followers are spam/bot/non-active https://sparktoro.com/tools/fake-followers-audit
Connected devices are no longer an innovation, rather an expectation. Sensor saturation has become reality. There is absolutely nothing special about connecting a device to the internet and collecting data from it anymore.#IoT as a buzzword describing the future is probably dead?

..receiving pleasure from reading C code: byte swap without a helper variable

Pushing an ILI9341 TFT to its limits with 60MHz DMA-enabled SPI on #ESP32 Correction: SPI can only run on 80/n frequencies [n between 1 and 8], so 8MHz, 8.89MHz, 10MHz, 11.43MHz, 16MHz, 20MHz, 26.67MHz, 40MHz, 80MHz . Setting SPI clock to 60MHz actually meant it got mapped to 40MHz, anything>60MHz meant setting to 80MHz. Thatβ¦

LiPo batteries for an upcoming #ESP32 e-paper display project arrived

Did another PCB revision to my #ESP32 TFT project to allow the use of a resistive touchscreen. Did that after seeing my daughter push the screen on a prototype of my non-touch version with a finger in an attempt to use the GUI.. obviously, button-controlled GUI is not intuitive

Made some moisture sensor PCBs for a flood detection #IoT project

Found a bug on my hardware designs
