I am getting this error on an ESP32C3 also.
Using version 2.0.4 of board install.
BUT.. still seems to mount some time later.

This code, generated by the free pfodDesignerV3 Andriod app, uses the bleBufferedSerial class to sends and receives unlimited UART data, in 20 byte blocks. Just write/read to/from the bleBufferedSerial (see https://www.forward.com.au/pfod/ESP32/index.html for a tutorial on using pfodDesignerV3 for E...

Here is an example of using the second UART on ESP32 C3 Remember to connect the ultrasonic TX to pin4 (ESP32 C3 RX) and the ultrasonic RX to pin5 (ESP32 C3 TX) // ESP32 C3 SERIAL1 (second UART) void setup() { Serial.begin(115200); Serial1.begin(115200,SERIAL_8N1, 4,5); //int8_t rxPin=4, int8_t txPin...

// ESP32 C3 SERIAL1 (second Uart) void setup() { Serial.begin(115200); Serial1.begin(115200,SERIAL_8N1, 4,5); //int8_t rxPin=4, int8_t txPin=5 } void loop() { if (Serial.available()) { // If anything comes in Serial (USB), Serial1.write(Serial.read()); // read it and send it out Serial1 (pins 4 & 5...

I am using the Arduino IDE ESP32 add on V1.0.2. A search of the code supplied with that package does not find CONFIG_WL_SECTOR_MODE which sets the performance/safe leveling when the sector size is 512, so I cannot change the from the default Performance setting in this case, the SD case. I dug a bit...

I found the
#if CONFIG_WL_SECTOR_MODE == 1
in esp-idf wear_levelling.cpp

but a search of ESP 1.0.2 package for Arduino does not include this define.

How can I set Safety mode for ware levelling in the Arduino ESP32 add on?

For Arduino timers see my instructable

Thanks for the tip.
I have enough pins for the extra CS.
The ESP32 docs says you can specify 3 CS pins for one SPI channel and then just use 'handles' to preform SPI on each device.
It is not clear how to do this in the ESP32 Arduino addon which does not use SPI handles.

I am trying to control 3 SPI slaves from one SPI connection using the Arduino add-on for ESP32. I can see that the 'standard' SPI is using CS0 but it is not clear to me how to set CS1 and CS2 and how to switch between them. The ESP32 docs talk about spi_bus_add_device( ), but the Arduino esp32_hal_s...
