HSPI_HOST, VSPI_HOST and VSPI not declared

[dalymople]

I am trying to compile a program for a ESP32 C3 in Arduino IDE and I am getting compile errors that HSPI_HOST, VSPI_HOST and VSPI are not defined.

It looks like the HAL headers for the C3 use SPI2_HOST and SPI3_HOST instead, I can't work out the alternative definition for VSPI, but I am trying to use HSPI so I just defined it not to conflict. Defining these before including the library seems to resolve the error, but I haven't tested with hardware yet.

In the ESP32c3 file "spi_types.h" I found the following:

typedef enum {
//SPI1 can be used as GPSPI only on ESP32
    SPI1_HOST=0,    ///< SPI1
    SPI2_HOST=1,    ///< SPI2
    SPI3_HOST=2,    ///< SPI3
} spi_host_device_t;

This matches the deffinitions in "spi_common.h" from an older version of the ESP-IDF (V3.3):

typedef enum {
    SPI_HOST=0,                     ///< SPI1, SPI
    HSPI_HOST=1,                    ///< SPI2, HSPI
    VSPI_HOST=2                     ///< SPI3, VSPI
} spi_host_device_t;

I haven't found a reference to "VSPI" but it looks like it should be the same as "VSPI_HOST"
If I define these before calling "#include <ESP32SPISlave.h>" it compiles just fine, but goes in a boot loop, once I try to run the actual code.

I have fixed the issue and made a pull request: #12

That resolved my issues in PlatformIO as well. 👍
Somehow these changes don't seem to be merged yet, so I manually had to alter the ESP32SPISlave.h file... 🤔
