Here is SD example code from esp-idf. Here is one header file for esp32 fatfs. use 4-line SD mode, consider the 10K pullup resistors on data lines code page: FF_CODE_PAGE : CONFIG_FATFS_CODEPAGE 437 US What is the biggest micro SD card for esp32 fatfs? 16GB? FAT = file allocation table FAT32 individual files on a FAT32 drive cannot exceed 4GB size limit. FAT32 partition must be less than 8TB. exFAT file system: extended file allocation table....
Use an Airport to setup a WiFi network. Then download the binary of Jaguar. Run the following commands one after another. The second command requires the WiFi credentials. Use CTRL+C to stop the third one. To run the forth and the fifth command, put your computer on the same WiFi network as the esp32 device. $./jag setup $./jag flash $./jag monitor $./jag scan $./jag run hello.toit
Stumbled on this repo. Run the modified code on one snowflake with 25 RGB LEDs (ws2812b-2020). Check the video tweet.
Start to look at the toolchain for Rust on ESP32 family modules. After some googling, here is the first result. Clearly the toolchain is working in its early stage. $ cargo build OK. Both espflash and espmonitor are working. Reference: Rust on ESP32 rust esp32 std demo
