nazarijtipusak080/esp32-sd-card-read-write-append@0.0.3
Contains nodes for working with an SD card on ESP32, also for the example I added nodes for working with a string.
In order for the SD card to be initialized and opened, it must be formatted as FAT16 or FAT32 (if it works with arduino, then everything is fine). IT IS IMPORTANT THAT THE FILE NAME MUST BEGIN WITH "/". OTHERWISE OPENING OR CREATING A FILE WILL BE A NODE ERROR. The example was tested on a regular ESP32. SPI PINS (MOSI -GPIO23, MISO - GPIO19, SCK - GPIO18) ARE INDICATED IN THE CODE. ESP32 MODELS OF DIFFERENT TYPES NEED TO BE SPECIFIED WITH THE DOCUMENTATION!!!
| Node | Description |
|---|---|
| parse-tabular-copy | Splits the incoming string line into parts depending on delimiter character. Outputs the specified part of string line |
| parse-tabular-byte | No description |
| string-namber-to-byte | Transforms a string into a number |
| string-number-to-number | Transforms a string into a number |
| parse-tabular-number | No description |
| sd-write-esp32 | The node allows the ESP32 controller to write files to the SD card. Data is written at the beginning of the file. IT IS IMPORTANT THAT THE FILE NAME MUST BEGIN WITH A "/" CHARACTER. OTHERWISE OPENING OR CREATING THE FILE WILL BE A NODE ERROR. |

| sd-read-esp32 | The node allows the ESP32 controller to read data from the SD card. IT IS IMPORTANT THAT THE FILE NAME MUST BEGIN WITH "/". OTHERWISE OPENING OR CREATING THE FILE WILL BE A NODE ERROR. |
| sd-append-esp32 | The node allows the ESP32 controller to write files to the SD card. Data is added to existing content. IT IS IMPORTANT THAT THE FILE NAME MUST BEGIN WITH A "/" CHARACTER. OTHERWISE OPENING OR CREATING THE FILE WILL BE A NODE ERROR. |
