ChibiOS Free Embedded RTOS

Yeah , found it and now it works perfectly fine.
thanks

I can't find this macro in hal_pal.h and hal_pal.c.
Do I have to define this macro PAL_STM32_OTYPE_OPENDRAIN in the header file of hal_pal.h???
Or this macro is already defined somewhere and I just have to make it TRUE.

These are my lines dor configuring the GPIO pins for stm32f407 discovery at ...

where is this macro defined???

Well, i2cstart() is called, it is not visible in the pic you can checkout main.c from git repo which I shared.

And when I enable the Debug assertion in chconf.h, I got following thing

does this mean my i2c clock is not ser properly??
what I can ...

What I mark out just know is that in logic analyzer output, as you can see
after the start signal both SCL and SDA lines are kept low for a period of time,
can that be the reason ????

I know and have checked that thing, as you can see in the logic analyzer,
MAG I2C 7 bit slave address is 0b0001101
and that is what I am sending from code and its reflected in Logic Analyzer output.

I even tried with another I2C slave device, but it every time shows this, I2C slave address not Ack ...

I have written a simple I2C Code for stm32f407 using the chibios HAL for interfacing mag QMC5883.
It's a Basic Single thread code, just trying to understand the Chibios HAL API for different peripherals.
Code is this: m

But on running the code, it always gives Error +4, meaning Slave address Not ...

Yeah, correct and I too have done and tried that.
So then when u connect to gdb via CLI and list the threads by info threads command, did it show u all the threads as it shows in chibistudio debug window.

Here I have attached the images again

Yeah I am using GDB and Openocd both for debugging, I started the openocd session via Chibistudio only
like this Screenshot 2021-07-21 093910.png and then just launching ...

Hi to all, I am new to Chibistudio and debugging its threads.
Now the thing is that when I use the debug window of chibistudio, it lists all the threads which are running as shown in this image.
