使用到的是rp2040的UART0,SPI0,SPI1,I2C1等接口,Pin角分布如下 SD卡和显示屏分别占用两个不同的SPI口。 2.程序烧写 烧写程序之前首先按住BOOT按键,然后按下RST按键,正常情况下系统将识别到一个usb大容量存储器。 3.相关资料地址(更新中) 链接:https://pan.baidu.com/s/1NxTLMia0J-86ML_2cyypqg 提取码...
I realized that I have another SD card setup, a Xiao expansion board, and I also happen to have a Xiao RP2040 that I haven't tried. I checked the schematic and the expansion board uses SPI0 for the SD card. So, time for some experiments... ...

PicoMemcard simplest device to build, only requires a Raspberry Pi Pico / RP2040-Zero PicoMemcard+ more complex but capable device. Supports additional features such as multiple memory card images but requires additional hardware (namely the microSD SPI expansion board). This approach was choosen...
The .vlw files must be uploaded to the processors FLASH filing system (SPIFFS, LittleFS or SD card) for use. Alternatively the .vlw files can be converted to C arrays (see "Smooth Font -> FLASH_Array" examples) and stored directly in FLASH as part of the compile process. The array bas...

and 1Kb would probably be too little for anyone who wants Eeprom. It has 2MB of Flash which can be used as if Eeprom if one only wants to store configuration settings or updating infrequently. It's easy enough to add Eeprom, SD Card and, one day hopefully, USB Memory stick and USB HD...
