Re: Are all ESP32's created the same??

I also have had similar reboot problems which seems to be due to the USB connected power supply. Once the ESPs are powered remotely with a stable supply no problems.. There is quite a power draw when the ESP connects to WIFI and it looks as if the USB power supply was limiting the unit. Been using E...

Hope this assists someone out there.... /* Measures the frequency of a square wave appliet to a digital input Uses a free running timer/counter fo...

ESP32 Github Core-- Is this a joke

Late last month I went through the , IMHO, crazy setup of the ESP32 into the Arduino IDE. This morning I updated using the same system. Maybe I am naive and old fashion but I understood that the whole basis of the Arduino environment was to provide a low tech high level entry into the AVR world. Thi...

Re: ESP32 not recognized by PC. No COM port problem!

I just purchased a new ESp32 yesterday and have exactly the same problem..I can see the USB connection and the correct port. The unit broadcasts an AP SSID of ESP_85EE26.
I cannot get any other activity...

Downloading to Excel mainly The CSV also allows easy use of parseInt() and definition of the length of the data If you do a search on SD cards one of the most usual application is data logging, so integers and floats from sensors You can of course write the data sequentially without the posn, but if...

Found it here is a second version using the same crude way to add and retrieve floats #include <SPIFFS.h> // This variation is based on the work of copercini //List Directories // Example:Spiffs_List_Dir(SPIFFS, "/", 0); // Lists down to number of levels required //========================...
