一、硬件准备 我这里用到了stm32f103c8t6、esp8266、7脚0.96寸oled屏幕。 二、stm32连接oled屏幕 我这里借鉴了大神得stm32连接oled屏幕 我这里用得是7脚得oled、他们得引脚有(需要了解更多看数据手册): 我使用的是通过硬件spi来控制oled屏幕,使用时先配置HAL库,我使用的SPI1,板子上学显示3个绿色引脚,分别是SCK...

主要介绍UART（通用异步收发器），是一种异步、全双工的通信方式。
// Parallel bus is only supported for the STM32 and ESP32 // Example below is for ESP32 Parallel interface with UNO displays // Tell the library to use 8 bit parallel mode (otherwise SPI is assumed) //#define TFT_PARALLEL_8_BIT // The ESP32 and TFT the pins used for testing are:...

LCD interface: The development board has a 1.28-inch screen with 4-wire SPI communication on board, the SPI rate can be increased to 80MHz, and the touch uses I2C communication (the development board uses GPIO2 to control the brightness of the backlight, and two MOS tube control switch co...
有人说ESP32没有CAN总线控制器,其实不然,只不过它被称作TWAI,two-wire automotive interface。这也是ESP32可以用来控制大疆M3508、M2006等电机的根本原因。由于官方放出的资料很少,所以不被大家所熟知。 ESP32的CAN控制器在功能上比STM32略逊一筹,同时技术披露较少,其硬件设计参数基本都是未知的。但从另一方面说...
一、首先配置并安装好platformio 可以参考我这篇帖子:如何安装 PlatformIO? 二、下载并安装对应的库文件 1.在PIOHOME的HOME里面创建一个工程配置如下 2.在PIOHOME的libraries里面搜索并安装这两个库到你的工程中 lv_arduino lv_arduino 添加lv_arduino到工程目录下 ...
