I am puzzled by the fact that none of these functions (SPI-begin, SPI-transfer, SPI->set*) returns any kind of error code. SPI->transfer returns 0 no matter what pins I map in the setup, so I don't think the communication is actually happening. The...
I am new to the ESP32 and electronics design in general, so please be patient with me. I am trying to use the PICO-V3-02 with a display (specifically an SSD1351) controller connected via 4-wire SPI. However, I cannot seem to figure out the SPI configuration of the Pico-v3-02. It...

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 (Not Connected). However, in the table in section 2.3, they are designated as defau...

1.1 ESP32中SPI ESP32集成了两个通用SPI控制器,可用作片外SPI主设备驱动的从节点 SPI2,有时也称为HSPI SPI3,有时也称为VSPI SPI2和SPI3具有独立的信号总线,分别具有相同的名称。 SPI从驱动程序允许将SPI外设用作全双工设备。驱动程序可以发送/接收最长64个字节的数据,或者使用DMA发送/接收更长的数据。但是,...
I am trying to connect the ESP32 Thing from Sparkfun to 3 SPI slaves (ADCs) but I am not able to finalize my pin assignment regarding the Slave Select (SS or CS) pinsCould I do the following: GPIO 23 -> MOSI GPIO 19 -> MISO...
In this ESP32 ESP-IDF SPIFFS web server project, we will create and store HTML and CSS files in SPI flash file system, and through which we will build a web server that will control the output GPIO pins of the ESP32 module by toggling the onboard LED. ...
ESP32和无线收发模块SPI通信 一、例程介绍 此例程是运行FOMO 轻量检测模型实现物体检测,Demo中已包含训练好的模型参数,无需再训练。 FOMO(Faster Objects, More Objects) 是由 Edgeimpulse 工程师提出的一种轻量级的目标检测模型,其主要特点是模型非常小,计算量也很小,表现出来就是速度非常快,精度也不错。FOMO 的...
