调用spi_bus_add_flash_device()将片外FLASH作为从设备挂载到SPI总线,并分配内存、填充esp_flash_t结构体、初始化CS信号线 调用esp_flash_init()与芯片进行通信(注意:目前多个FLASH芯片可以连接到同意总线,但尚不支持在同一个SPI总线上使用esp_flash_*和spi_device_*设备) 访问FLASH 一般来说应尽量避免对主SPI ...

After a break of a couple of months I came back to do firmware developement and big surprise can't flash my ESP32. At least on my desktop. Still works on my laptop. So: - I rather think it is not a hardware issue since it works on my laptop. - It is not a USB HUB in betw...
如何使用ESP32C3驱动SPI NAND flash 最近收到了一片国产工业级SD NAND,可以替代SD卡,容量大,贴片封装,非常适合做飞控"黑匣子"。 不用写驱动程序自带坏块管理的NAND Flash(贴片式TF卡),尺寸小巧,简单易用,兼容性强,稳定可靠,固件可定制,LGA-8封装,标准SDIO接口,兼容SPI/SD接口,兼容各大MCU平台,可替代普通TF卡...

注意: GPIO0 和 GPIO2 是 strapping pin, 它们可能会影响启动. GPIO1 和 GPIO3 是 REPL串口 TX RX 引脚. GPIO6-11 一般连接到 SPI flash. GPIO34-39 只能被设置为输入模式,并且软件没有上拉/下拉功能。 ADC (模数转换)¶ 详见machine.ADC: ...
开发板管理器中,搜索esp32,安装2.0.13版本(需要安装2.0.16之前版本,不然不匹配tft_eSPI库,程序会重启)。 img 2. 安装tft_eSPI库 2.1. 驱动库安装 库管理中,搜索tft_eSPI,安装最新版本2.5.43。 img 2.2. 库代码修改 这里需要修改引脚代码,适配st7789驱动。
