How to use the AN4636(Application note)

[MinHyukKim]

Hello STM,

currently, I am confirming the AN4636 document

This document is about LC sensor.

My require is as follows,

​I want to know how to use the firmware provided.

I am currently trying to use the firmware provided using stm32cubeMX or stm32cubeIDE, but it does not work.

I am testing with a nucleoboard based on the stm32L4xx series, and I have tried many times to use the provided firmware 'STM32CubeExpansion-LC-Sensor-L4-V1.0.0' 

but I found it impossible.

I want to know what kind of environment I need to configure to use this firmware.

Thanks​

Hello @MinHyukKim​ and welcome to the Community :smiling_face_with_smiling_eyes:

After downloading the firmware in question from here

You can either use stm32CubeIDE by following this path :

X-CUBE-CSENSOR_V2.0.0\STM32CubeExpansion_LC_Sensor_L4_V1.0.0\Projects\STM32L476RG-Nucleo\SW4STM32\AN4636_STM32L476RG

Or you can use IAR workbench by following this path :

X-CUBE-CSENSOR_V2.0.0\STM32CubeExpansion_LC_Sensor_L4_V1.0.0\Projects\STM32L476RG-Nucleo\EWARM

Hi, Sarra

Thanks you for your reply

I replied using my company email. If you didn't receive the mail, it could be occurred a security problem by the attached file. If so, please reply to me again.

Hi Sarra

Thank you for your reply.

I already imported the project you suggested from stm-32-CUbe-IDE and tested it and confirmed that it was not being built.

By default, the header of the hal-driver is not referenced.

Also, because of this problem, I have created a blank project and implanted AN4636 example.

As a result, it can be built, but when I ran it in debug mode, I found that it stopped in an infinite loop in the first-cal part.

I will attach the project I made, so please check it.

** When I created this project, I didn't use cubemx and implemented it only with code.

Thanks.
