Re: non blocking semaphore in task

yes, it does return a BaseType_t. if it is pdPass you successfully obtained the token, otherwise, you will get pdFALSE which indicated either the token was not available or timeout.
Wbt using an event group if you need to look into multiple conditions?

Re: RX buffer issue while reading same UART from two different tasks

yes u r correct, internally UART maintains the semaphore. so what happens is, when I switch to a different task through interrupt routine, UART gets blocked, and interrupt task cannot take the semaphore.

RX buffer issue while reading same UART from two different tasks

I have two freeRTOS tasks that receive from the same UART port. However, when moving from one task to another, my buffer gets filled and my algorithms can't proceed with this fault because I take the length which comes from uart_read_bytes() . I move from the first task to the second task when an in...

As you can see the API reference says how should we do it, but the conventional isr handers are missing in these APIs. can someone send me a...

Re: esp_http_client.h: No such file or directory

home directory

Code: Select all

cmake_minimum_required(VERSION 3.5)

set(EXTRA_COMPONENT_DIRS lib)

include($ENV{IDF_PATH}/tools/cmake/project.cmake)
under http directory

Code: Select all

idf_component_register(
    SRCS "HTTP.cpp"
    INCLUDE_DIRS .
)
Hope this is what you were asking for?

esp_http_client.h: No such file or directory

I am having a weird issue with ESP-IDF. In my project directory if I call esp_http_client from a main or from a library in the same directory It works. But when I shift the library to somewhere else, this particular library can not be imported. I already got RFID, gpio, and wifi libraries set up in ...
