I have a project with the ESP32-C3 chip, and I need to use the SPI pins (SPICS0, SPICLK, SPIQ, SPID) as GPIOs since I don't have any more available pins. I understand that these are internally connected to the
spi.readinto(buf, 0xff) # 读取到给定的缓冲区,并输出在MOSI输出0xff spi.write(b'12345') # 向MOSI写5个字节 buf = bytearray(4) # 创建一个缓冲区 spi.write_readinto(b'1234', buf) # 写MOSI并同时读取内容到缓冲区 spi.write_readinto(buf, buf) # 写buf内容到MOSI并读取MISO内容到buf 1....

Hello! I wondered if there are specific pins to use for I2C and SPI for the ESP32-C3-MINI? I haven't been able to find this in a datasheet/ anywhere else. Is there room for both I2C and SPI ? Thanks in advance!MicroController Posts: 2181 Joined: Mon Oct 17, 2022 7:38 pm ...
Re: ESP32 S3 MINI SPI Pins by James_7122 » Fri Dec 15, 2023 7:03 am Now it's getting very strange. I wanted to test the pins themselves, so I used the following "blinky" code and tested with a multimeter. Pin 36 fluctuates between 3.3V and 2.4V, and pin 37 fluctuates betwe...
