where to connect XDCS and SDCS pin in ESP32PICO D4 from VS1053? please help to solve this Reply Deb Deep Sett September 9, 2022 at 11:21 am There is a mistake in info in UART pins usage. Mostly a typo. Check fo

With the ESP32 you can decide which pins are UART,I2C, orSPI– you just need to set that on the code. This is possible due to the ESP32 chip’s multiplexing feature that allows to assign multiple functions to the same pin. If you don’t set them on the code, the pins will be ...
You must use // 38400 or slower in these cases, or use some kind of external separate // crystal solution for the UART timer. // initialize device Serial.println(F("Initializing I2C devices...")); mpu.initialize(); pinMode(INTERRUPT_PIN, INPUT); // verify connection Serial.println(F(...
Enabling the ESP32 to wake up using a touchpin is simple. In the Arduino IDE, you need to use the following function—pass as argument the touch pin and the touch threshold: touchSleepWakeUpEnable(TOUCH_PIN,THRESHOLD); Code Let’s see how this works using an example from the library. ...
