# I/O
Pins in my ESP32S3 board. Use menuconfig to change the values
| Function | Pin |
| ----------------------------- | ----- |
| CONFIG_SD2IEC_SD_PIN_MOSI | 47 |
| CONFIG_SD2IEC_SD_PIN_MISO | 41 |
| CONFIG_SD2IEC_SD_PIN_CLK | 48 |
| CONFIG_SD2IEC_SD_PIN_CS | 42 |
| CONFIG_SD2IEC_PIN_CLK | 1 |
| CONFIG_SD2IEC_PIN_DATA | 2 |
| CONFIG_SD2IEC_PIN_ATN | 40 |
| CONFIG_SD2IEC_PIN_SRQ | -1 |
| CONFIG_SD2IEC_PIN_LED_BUSY | -1 |
| CONFIG_SD2IEC_PIN_LED_DIRTY | -1 |
Use a level shifter for CLK,DATA and ATN pins.
# Building
Use [ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/stable/esp32/get-started/index.html) to compile.
```
cp sdkconfig.esp32s3 sdkconfig
idf.py menuconfig
idf.py -p /dev/ttyUSB0 build flash monitor
```
# Storage
SD2IEC have a concept of partitions. These are not FAT or SD card partitions.
Partition 0 is the FAT file system in SDCARD.
Partition 1 is a part of board flash as a FAT file system. You can use it for storing utilities like file browsers and fast loaders.

# Notes
Fastloaders do not work reliably
M2I is broken.
Changelists are broken.
Simple file loading and saving works.
