I2c problems #46

Closed winny2809 closed 5 years ago

winny2809 commented 5 years ago

Is it possible to have some examples regarding the i2c device and if possible also of the device pcf8575?

I can't understand many things about it, and I would have some examples, maybe even an initial configuration :-(

UncleRus commented 5 years ago

See example

winny2809 commented 5 years ago

Thank you very much for the timeliness with which you helped me, very kind. I integrated his library into my esp-idf system in Platformio, it is, unfortunately it generates me a lot of errors and I can not find the cause. Could you tell me what I'm wrong?

lib_error

trombik commented 5 years ago

i cannot tell where the issue is, but looks to me that your build system is not correctly configured. more information would certainly help.

by the way, platformio does not support esp-idf very well, e.g. sdkconfig handling and other build-related issues. you need to understand and translate various build flags. the tool-chains they ship are often lagged behind.

winny2809 commented 5 years ago

Below, I attached the results of the compilation. Of course, as you say, platformer has problems especially with regard to "sdkconfig". Usually, however, I solve by inserting the various variables within the C file, such as in this case I put in the file i2cdev.c this definition: #define CONFIG_I2CDEV_TIMEOUT 1000 Unfortunately however, I do not understand the cause of all these mistakes, it will definitely be a nonsense to solve, but you need someone with more experience than me.

winny2809 commented 5 years ago

The main errors I find in these lines of code:

define I2C_DEV_TAKE_MUTEX(dev) do { \

    esp_err_t __ = i2c_dev_take_mutex(dev); \

    if (__ != ESP_OK) return __;\

} while (0)

define I2C_DEV_GIVE_MUTEX(dev) do { \

    esp_err_t __ = i2c_dev_give_mutex(dev); \

    if (__ != ESP_OK) return __;\

} while (0)

define I2C_DEV_CHECK(dev,X) do { \

    esp_err_t ___ = X; \

    if (___ != ESP_OK) { \

        I2C_DEV_GIVE_MUTEX(dev); \

        return ___; \

    } \

} while (0)

and also in the definitions of SEMAPHORE... It seems to me that the problems come from SEMAPHORE or at least from The Freertos. In my file c_cpp_properties.json i have this code:

"intelliSenseMode": "clang-x64", "cStandard": "c99", "cppStandard": "c++11", "compilerPath": "\"C:/Users/Winny/.platformio/packages/toolchain-xtensa32/bin/xtensa-esp32-elf-gcc.exe\" -mlongcalls"

I hope this will help you understand my problem

what would happen if you add #include <esp_err.h> to lib/i2cdev/i2cdev.h? something like:

UncleRus commented 5 years ago

I'm at a loss. I've never dealt with the PlatformIO. Could you try to manually build examples using make or idf.py?

winny2809 commented 5 years ago

Yes now i try it

winny2809 commented 5 years ago

OK, I've rethought it and it all went a good fine. Now come I proceed with visual studio code (platformio)?

UncleRus commented 5 years ago

Since the build of examples with the recommended method was successful, I believe that you should ask questions related to the platformIO or VisualStudio on the esp-32 forum. I am closing this issue.

daverathbone commented 2 years ago

Would like to say that UncleRus could program the I2C with the paths he claims he has , then try it on another PC with the advice he gives out , then he also would find it does not work!... it's not a native path in platformIO or Visual Studio plugin tools. Or Eclipse... Better I write one from scratch would have taken me less time... What a pain..........

trombik commented 2 years ago

we support esp-idf as a build system. I'm sorry to hear that your favourite tool doesn't work with the libraries. however, as the issue doesn't happen with the supported build system, I'd like to say that our efforts to help diagnosing the issue is only a best efforts basis. it would be faster to solve the issue if you ask someone who knows your tool than adding another "it doesn't work" comment without any details. thanks for your understanding.
