ESP32-WROOM-32D and ESP32-WROOM-32U are powerful, generic Wi-Fi+BT+BLE MCU modules that target a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding....
烧录了MicroPython固件后的内存占用情况。 The WROOM device has 4 MB of Flash and about 500k of RAM. The Flash memory is used for the firmware and the file system. Most of the RAM is used by the RTOS and MicroPython interpreter itself, such that for the Python Heap 110k of RAM remain. ...

ESP32-WROOM模组没有预留外接PSRAM的接口,游戏机只能运行1024K以下大小的游戏,载入速度慢,无JPG与PNG图片解码支持,界面简陋。 ESP32-S模组预留外接PSRAM的接口,ESP32-S模组 + PSRAM = ESP32-WROVER模组。性能更强,游戏载入快。 软件方案 根据GitHub上的NCAT项目修改而来。使用Arduino开发 NCAT项目地址:GitHub - ...

首先你需要一块ESP32开发板,本人使用的是一块ESP32-WROOM-32核心板,关于ESP32各个型号的区别可以进入乐鑫官网查看。 其次是一块屏幕,我使用的是一块2.8寸(240*320)的tft屏幕,原作者使用的屏幕尺寸较小,故换了块大的,驱动是ST7789,使用spi通信协议。 电脑,这个不用说了。 能开热点的手机,因为ESP32无法连接处...

我用的模块是ESP32-S3-WROOM-2 N32R8V,Flash是32M的,PSRAM是8M的 问题: 1. 我用IDF4.4编译的时候,Flash设置最大支持到16M,压根没有32M的选项,在不改变IDF环境的前提下,如何设置成32M? 2. menuconfig打开 Support for external, SPI-connected RAM 选项后,通过gc.mem_free()得到的数值是3663856,也就是...
