Your custom PCB should have a reset circuit, usually a resistor to Vcc and a capacitor to ground, on the EN input. Do you have that?

Thanks for your answer. Yes I have both

Hi all,

I have an ESP32 on a custom PCB, and I use this board to program the ESP - I hooked the ESP-Prog board to my PCB with wires:

Hi, I'm having issues with changing operating modes of an ESP32 chip.
Some details: I'm using Arduino IDE, and I want to program the ESP32 and run it with my code. For now I'm using a very simple code that just prints to serial. I have access to the GPIO0 and GPIO2 and I can also manually connect ...

Hi,

I'm using the SPI on an ESP32 chip. I need to read a stream of data on the ESP SPI master at 2MS/s, each sample is 1 byte. So I have 2 Mbytes each second.
For now I'm using a for loop that reads x amount of samples, I have 16MHz SPI CLK which is enough, the problem is that there is a delay ...

Hi,
I'm following this https://github.com/espressif/vscode-esp-idf-extension/blob/master/docs/tutorial/install.md
at step 5, when I do ESP-IDF: Configure ESP-IDF extension >> Install, it fails with error 404:

Hi all,

I'm writing a code for the ESP32 in Arduino IDE with C++ objects defined in C++ files. The code works like this, it configures an interrupt on a pin of the ESP32 and when it receives the interrupt, it reads a message on the SPI as master and then it prints the message to serial.
1) I had ...

Even though the datasheet says "Notice:", I didn't notice that! Thank you

Hi,

I have an ESP32-PICO-D4 chip and a very simple Arduino that toggles its pins using digitalWrite(pin, HIGH/LOW);
I can toggle different pins, no problem, but specifically pin no.25 which the datasheet reports as
Name: IO16
Functions: GPIO16, HS1_DATA4, U2RXD, EMAC_CLK_OUT

doesn't work. Any ...

Hi all,

I have a TinyPico board which has an ESP32. In my Arduino code I have a class that defines the callback onWrite to read Bluetooth messages.


class MyCallbacks: public BLECharacteristicCallbacks {

// on received bluetooth message
void onWrite(BLECharacteristic *pCharacteristic ...
