Missing type declaration in i2c.html sample code (IDFGH-14295)

[wellssam100]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

In /esp-idf/en/v5.3.2/esp32/api-reference/peripherals/i2c.html there is sample code for using the Slave Read, written here.

On line 25, the following is written: s_receive_queue = xQueueCreate(1, sizeof(i2c_slave_rx_done_event_data_t));
Which should updated to be: QueueHandle_t s_receive_queue = xQueueCreate(1, sizeof(i2c_slave_rx_done_event_data_t));

Another example is given in components/freertos/FreeRTOS-Kernel/include/freertos/queue.h line 126, which uses the QueueHandle_t type for declaration.

I believe that this code was written with some variables declared outside of the scope of the code and this is an artifact of that.

Thanks for your report, and we will fix it. However, we have a more useful i2c slave since v5.4 called i2c_slave_v2, and we encourage you to use that one. For this old version of i2c slave, we will not treat it as a high periority fix. So I'm going to close this one and find proper time to fix this doc on 5.3, thank you!
