Monitoring STMTouch driver variables using STM

Studio

The main parameters to trim a touch sensing application are:

•

The channel references, the “Ref” element of an array of TSL_ChannelData_T

structure

•

The channel deltas, the “Delta” element of an array of TSL_ChannelData_T structure

•

The object states, the “StateId” element of an array of TSL_TouchKeyData_T structure

or a TSL_LinRotData_T structure

This list is not exhaustive and will depends on the application.

The following procedure provides an easy way to import such variables:

1.

Open STM Studio

2.

Right-click in the “Display Variables” tab and select “Import...” or select the “File/Import

Variables” menu

3.

In the “Import variables from executable” window,

a)

select your application Elf file (.elf, .out or .axf) Through the “Executable file” field

using the browse button

b)

check the “Expand table elements” check-box

c)

Select the “Store executable path relatively to the user setting file” check box to

use relative path.

d)

enter “Ref” in the “Show symbol containing...” text box

e)

select “Add variables to the display variables table” in the Variables list box

f)

select the “.Ref” ended variables and click on “Import” button or Ctrl+Click to

operate an uncontinuous multi-selection

g)

repeat step d) and f) with Delta

h)

repeat step d) and f) with StateId

i)

click “Close” button
