Dear Nikhil,
I attach one button of seeting, Because I only try to modify this dsRam parameter.
The current design is no problem, but it I want to add the adjustment method to change the sensitivity after production assembly.
In the test program, I added like red circled on the below.
When press num 4~9 can change num1 button finger threshold value.
Regards
Adam
Hi @AdamCheng,
The current design is no problem >>> Okay.
The procedure followed by you is correct. The finger threshold does get changed when you use
CapSense_dsRam.wdgtList.number1.fingerTh = <number>;
I am attaching my project here (done on the 4200M Pioneer kit).
In my project, I have the total scan time approximately equal to 5ms. In the code, the conditions are given such that for every 5 seconds, the finger threshold gets updated between 90 and 70 (I am starting the application with an initial finger threshold of 100).
You may verify the same by going to debug mode and observing the dsRam contents.
Figure 1: Initially, the finger threshold is equal to 100 (0x64)
Figure 2: After approximately 5 seconds, the finger threshold is changed to 90 (0x5A)
Figure 3: Again, after approximately 5 seconds, the finger threshold is changed to 70 (0x46)
Regards,
Nikhil
