IWRL1432BOOST: UARTB Interrupt Mode Configuration on IWRL1432 for Level Sensing Application

Part Number: IWRL1432BOOST
Other Parts Discussed in Thread: IWRL1432, SYSCONFIG

Tool/software:

Hello TI Experts,

I'm currently working with the IWRL1432 for a level sensing application, and I need to enable UARTB in interrupt (callback) mode for reading. Below is a summary of my existing setup and the steps I followed to implement this feature, along with the issues I'm encountering.

Existing Setup:

I have enabled Quick Eval in the SysConfig file to hardcode the CLI configurations (in mmw_cli.c).
I'm currently sending the level sensing data via UART using the CLI_write function.
The transmitted data is successfully visible in a serial monitor (screenshot attached for reference).

Steps Taken to Enable UARTB Interrupt Mode:

In SysConfig, I changed the UART read transfer mode to Callback and assigned a read transfer callback function.
The callback function definition was added to level_sensing.c.
I attempted to reinitialize the UART and assign the callback each time the callback function is executed.

Issue:

After these changes, I encountered several errors as a Garbage. I have attached the modified code and error logs for reference.

I would appreciate your help in resolving the errors and ensuring proper implementation of UARTB in interrupt mode. Please let me know if additional information is needed.

Thanks & Regards,
Rakesh Amara

Hi,

Were you able to trace on where the error log was getting printed? Is this a custom log?

Did you take a look at uart callback example?

Regards

Hello Sharan,

It’s not a custom log — the statement you’re referring to is already present in the CLI_task function within the mmw_cli.c file.
Could you please help verify this against my current setup?

Thanks,
Rakesh

Sharan,

Any updates?

I went through the UART Callback example. Although it’s labeled as “callback,” the implementation seems to behave more like blocking mode — it waits for the data to be received, and only then the callback is triggered and the semaphore is released.

Could you clarify — is this truly interrupt mode, or is it a blocking mechanism with interrupt-based signaling?

Hi,

It looks like you have multiple threads regarding this. Which thread do you want to proceed further with?
