In building "https://github.com/manuelbl/ttn-esp32" examples I have run across symbol or field could not be resolved errors. The programs seem to execute correctly so it appears this is an indexer issue. A particular symbol is "max_transfer_sz." It is found in C:/Espressif/frameworks/esp-idf-v4.4.1/components/driver/include/driver/spicommon.h but not in the project/esp_idf_components directory.
The errors go away when I enable "Index source and header files opened in editor" and open the spicommon.h file above.
I have not found an option to include this for the indexer nor can I get it to work by adding the directory to the include directories.
I'm not sure if this is a bug, or I just need to find the correct options.
This is on Windows 11

Re: Eclipse ESP-IDF Indexer Issue: Symbol could not be resolved
Hello,
I quickly configured the setup with the repo you mentioned.
As I see max_transfer_sz is defined in the spi_common and spi_slave so the indexer is unable to resolve conflict correctly. Let us look into this and provide a fix.
Could you also provide a small snippet of how you're using code with max_transfer_sz variable.
Thanks

Re: Eclipse ESP-IDF Indexer Issue: Symbol could not be resolved
The snippet is:
The only part I added here is initArduino().
All the spi_bus... symbols have the same error.
I don't believe spi_slave mode is necessary for this code.
Thanks for your response.
Code: Select all
extern "C" void app_main(void)
{
initArduino();
esp_err_t err;
// Initialize the GPIO ISR handler service
err = gpio_install_isr_service(ESP_INTR_FLAG_IRAM);
ESP_ERROR_CHECK(err);
// Initialize the NVS (non-volatile storage) for saving and restoring the keys
err = nvs_flash_init();
ESP_ERROR_CHECK(err);
// Initialize SPI bus
spi_bus_config_t spi_bus_config;
spi_bus_config.miso_io_num = TTN_PIN_SPI_MISO;
spi_bus_config.mosi_io_num = TTN_PIN_SPI_MOSI;
spi_bus_config.sclk_io_num = TTN_PIN_SPI_SCLK;
spi_bus_config.quadwp_io_num = -1;
spi_bus_config.quadhd_io_num = -1;
spi_bus_config.max_transfer_sz = 0;
err = spi_bus_initialize(TTN_SPI_HOST, &spi_bus_config, TTN_SPI_DMA_CHAN);
ESP_ERROR_CHECK(err);
// Configure the SX127x pins
ttn.configurePins(TTN_SPI_HOST, TTN_PIN_NSS, TTN_PIN_RXTX, TTN_PIN_RST, TTN_PIN_DIO0, TTN_PIN_DIO1);
All the spi_bus... symbols have the same error.
I don't believe spi_slave mode is necessary for this code.
Thanks for your response.

Re: Eclipse ESP-IDF Indexer Issue: Symbol could not be resolved
Hello,
Can you try turning off "Allow heuristic resolution of includes" from the Indexer preferences? I see all symbols and includes are resolved after this. Please find the screenshots.

Re: Eclipse ESP-IDF Indexer Issue: Symbol could not be resolved
That definitely helps. The errors disappear. They reappear when I change the editor window to another file and then back to main. This solves my problem, I don't have to sort through false errors.
Thanks for your help
