Thank you for the reply.
Using VSPI and HSPI at the same time affects the overall speed of both?
Recently I had an issue. I ran different tasks with SPI SD card and another with gyro I2C. The I2c often returned -1 instead of the correct value. This is was caused by SPI that block the I2C ...

ESP-Wroom-32D external ADC - SPI or I2C?
Hello everyone,
I am struggling with a huge problem (for my inexperience)!
I am using a ESP-Wroom-32D ad I'm making my own PCB.
I need to acquire at 1000Hz analog signals form external sensors and I noticed that the ESP32's adc is not very usable for high precision measures. So, I decided to use ...
