How to use FreeMASTER for touch tuning?

sandhyash — Wed, 28 Aug 2019 14:06:53 GMT

Hello all,

I am using the NXP Touch software (NT) library for my development. I am working on the MKE15Z128VLH7 controller and we have a custom hardware.

I need to tune the touch parameters using uSAFA key detection algorithm.

I was trying to use the FreeMASTER software to tune the touch parameters.

I am able to successfully execute the following steps when using FreeMASTER version 2.5.

1. Establish connection with the hardware, using Plug-in mode - FreeMASTER Segger/JLink Communication Plug in.

2. Load the .out file to monitor the variables.

3. Add the variables to monitor in the Oscilloscope block.

I am failing to execute the following steps:

1. Not able to view/capture a waveform upon the touch event.

2. Not able to view the Control Page.

(as mentioned in the - NXP Touch Library Reference Manual - NT20RM. "The FreeMASTER automatically generates
the HTML pages for visualization touch quantities in real time according to the current configuration of the embedded application using TSA tables". )

When I checked the code for Freemaster - freemaster_cfg.h. I found that the following communication interfaces are available which needs to be set accordingly.

#define FMSTR_SCI_BASE_DYNAMIC

#define FMSTR_DISABLE
#define FMSTR_USE_SCI
#define FMSTR_USE_LPUART
#define FMSTR_USE_FLEXCAN
#define FMSTR_USE_USB_CDC
#define FMSTR_USE_PDBDM

#define FMSTR_FLEXCAN_TXMB
#define FMSTR_FLEXCAN_RXMB

When we use the JLink which of the above would be applicable?

Also, the FreeMASTER version is 2.0

/* Define global version macro */
#define FMSTR_VERSION 0x00020000 /* 2.0.0 */

Is it okay to use 2.5? I was not able to connect with JLink using 2.0.

Could you please suggest the next steps I need to follow?

Thanks and regards,

Sandhya Sharma

Hello Sandhya Sharma

The steps to run the freemaster can be found on this link: https://community.nxp.com/docs/DOC-341890

The file that opens the control panel is an xxx.pmp file and can be located at src file in your project folder.

About the macros I suggest you to download the fmstr_example_uart file from the SDK. That example can be used as reference.

Let me know if this is helpful

Best regards,

Omar
