Why does the datasheet mention that using SPI pins as GPIO is not recommended instead of explicitly stating that you can't? Thanks again. Because technically, it's possible to add another SPI device in parallel with the flash, and you'd use those pins then. In practice, this has a ...
Re: ESP32 S3 MINI SPI Pins by lbernstone » Fri Dec 15, 2023 4:00 pm This sounds like normal operation for an SPI bus. If there is a lot of variability of the voltage level, that could imply you don't have enough capacitance and filtering on the devices. Look at the datasheets...

SPI receiver (slave) example. This example is supposed to work together with the SPI sender. It uses the standard SPI pins (MISO, MOSI, SCLK, CS) to transmit data over in a full-duplex fashion, that is, while the master puts data on the MOSI pin, the slave puts its own ...
可以使用硬件SPI也可以使用软件模拟SPI,只需要更改相应的引脚号即可 在文件的第203行下面定义ESP32引脚。 ESP32与屏幕链接引脚: // For ESP32 Dev board (only tested with ILI9341 display) // The hardware SPI can be mapped to any pins //#define TFT_MISO 19 ...
关键点:虽然pins_arduino.h中有I2C和SPI的引脚配置,但我们完全是可以根据我们的需求进行修改的,ESP32芯片也是支持的。 /* init code */ bool initialize() { if(!m_initialized) { /* Device Reset */ gpio_set_level((gpio_num_t)pin_res, 0); ...
By default, ESP32 has two SPI communication channels VSPI and HSPI and the following table provides the default SPI pins for both channels. But if we can also map these pins to other GPIO pins also in Arduino or esp-idf. You can read this in-depth guide on ESP32 SPI communication: ...
