Hello dejans,

No semaphore usage in SPI driver files under the path nor in SPI test code.

Hi,

Have you checked zephyr\drivers\spi?

This I saw in the documentation, rather I am asking for a sample code & project demonstrating the use of semaphore and these APIs.

Hi,

You could try searching for functions k_sem_define(), k_sem_give() and k_sem_take() from VS Code. For example, you could look at zephyr\drivers\spi.

Hello dejans,

I am aware of

I am requesting for a sample project on usage of semaphores.

Hi,

You can get more information about semaphores under Zephyr semaphores.

Hello sipan112,

[quote userid="113039" url="~/f/nordic-q-a/84221/request-a-sample-code-for-zephyr-semaphore-dependent-spi-api-calls/350336#350336"]check this[/quote]

This is just a sample app for SPI_Write() demo.

I am rather looking for a sample project demonstrating use of semaphore.

[quote userid="108934" url="~/f/nordic-q-a/84221/request-a-sample-code-for-zephyr-semaphore-dependent-spi-api-calls"]wherein i want semaphore in place at the HAL, which can avoid multiple slaves' concurrent access.[/quote][quote userid="108934" url="~/f/nordic-q-a/84221/request-a-sample-code-for-zephyr-semaphore-dependent-spi-api-calls"]Can you kindly point me to any such semaphore logic or sample program available.[/quote]
