Re: ESP32-C3 SPI Pins as GPIO by Mateo4865 » Wed Mar 06, 2024 2:19 pm SPIHD (GPIO12) and SPIWP (GPIO13) Pins are available to use as GPIO? In the Pin Layout section (2.1) of the datasheet, Pins 19 and 20 (SPIHD and SPIWP) of the ESP32C3-FH4 are labeled as NC ...

I am trying to connect my ST7735 to my esp32 devkit v1 via HSPI pins. Unfortunatly, I can't make it work. My code: Code: Select all #include <Adafruit_GFX.h> #include <Adafruit_ST7735.h> #include <SPI.h> #define TFT_CS 15 #define TFT_DC 2 #define TFT_RST 4 #define TF...
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 ...
// Initialize the SPI bus using the default hardware SPI pins SPI.begin(); // Your setup code here } void loop() { // Use vspi for VSPI communication vspi->begin(); // Your VSPI code here vspi->end(); // End VSPI communication // Use hspi for HSPI communication hspi->be...
To use UART1, we have to redefine the pins. Because default pins of UART1 such as GPIO9 and GPIO10 are internally connected to the SPI flash memory. Also, on some ESP32 boards, they are even exposed on the pinout headers. Hence, we can not use UART2 directly without reassigning pins...
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); ...
