Re: ESP32-S3-WROOM-1 preferred PINs for I2C and CAN PostbyESP_Sprite»Tue Sep 14, 2021 1:08 am You can; it's OK to use input-only pins for input-only functionality. (Thanks for pointing that out, it slipped my mind that CAN has a RX pin before the transceiver.) ...
Most of the I/O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-S3-DevKitC-1 on a breadboard. We particularly like that there's a debug UART/USB port and...
The ADC does not support qspi and is limited to SPI. I am planing to use an OLED (qspi) with touch(I2C) and a micro sd card (SPI). Yet to be added is a 16 Bit Shift Register with the remaining pins GPIO16,GPIO39-42. Can I use 3 stand SPI and one qSPI combination?

如果没有波形显示，可能是由以下几个原因导致的：1. **I2C引脚连接问题**：确保I2C的SDA（数据线）...
ESP32-S3 has four strapping pins: • GPIO0 • GPIO45 • GPIO46 • GPIO3 Software can read the values of corresponding bits from register “GPIO_STRAPPING”. During the chip’s system reset (power-on-reset, RTC watchdog reset, brownout reset, analog super watchdog reset, and ...
