I would put a big polarised capacitor on the output 220uF or so to assist with surges

Try this

There are three hardware based serial ports (0,1,2) on the ESP32 without using hardware serial Have a look at an IO cross reference for the IO associated with each port You can use by calls such as this HardwareSerial Serial1(1); #define SERIAL1_RXPIN 25 #define SERIAL1_TXPIN 26 Serial1.begin(57600,...

Thanks for that I was using I2C at the same time.. When I removed the I2C the problems went away.. I am convinces that ESP32 is just not a good product if you attempt to use too many features.. So I have split my program into two ESPs, one for WIFI connect and one for logic. Works only because ESP i...

Serial1.setRxBufferSize(1024);

There are two ways In Arduino IDE the board manager can be used to select ESP32 and update the latest 'released to Arduino" ESp32 files. These are not the latest on Github If you use the Github then this can upload the latest version In both cases the files are located in a hardware folder in your A...

Downloaded the latest ESP32 to Arduino IDE and found that every time my PC or phone looks for the AP connection then the ESP32 crashes. Usually this is when 'seeking IP Address"
Has anyone had issues with this new version. Any fixes?

The USB connection actually uses TX0 and RXO so you can put another power supply on and use the USB only for logging via Serial.print etc.

You also have two other serial outputs that you can connect to a FTDI unit and look at the output with Putty or similar

If you search google Doit ESP32 you will find a lot of people with this problem. it appears that their design is susceptible to low voltage, especially if powered from a USB port alone. Most people have got over this by adding in another power supply to Vin or to 3.3V.. My solution is to buy from an...

I have deduced that reading an analog under a timed interrupt interferes with my digital interrupt. A Google search shows others have had this problem as well.. I tried some of the workarounds but no success Has anyone a proper solution for this. The attached code is a much simplified program. If th...
