I can receive the JSON string from the server with this function but it is truncated - the end is not a correct ending for a JSON string. I believe I have buffer overflow. How can I change the buffer size? Using Arduino IDE 2.2.1 and Espressif ESP32 board 2.0.14. Thanks, Theron WIerenga // Retrieve ...

Changed priority on core 0 from 1 to 0. Flickering remains, perhaps a little worse. Not sure how to do I2S peripheral in parallel ('LCD') mode to more-or-less automatically scan your LEDs without using any CPU time. Can you point me to an explanation. Attached the schematic of my circuit so you can ...

I have a working digital clock program using 7 segment LEDs. Both cores are used, core 0, set at priority 1, simply scans the LEDs by using 8 GPIO pins to set the 7 segments and then enabling that digit. Core 1 does everything else. 1. Checks if WiFI is still connected. 2. Checks the RTC to see if a...

Found my problem, I had pin 12 held high. 12 (MTDI) If driven High, flash voltage (VDD_SDIO) is 1.8V not default 3.3V. Has internal pull-down, so unconnected = Low = 3.3V. May prevent flashing and/or booting if 3.3V flash is used and this pin is pulled high, causing the flash to brownout. See the ES...

Greetings,

Looks like I've damaged my bootloader on ESP32. How can I re-install the bootloader?

Thanks, Theron Wierenga
