Using TSS_Library with MQX-Lite

[ViniciusHoff]

Hi,

I am designing a MQX-Lite project with four touch button, using the TSS_Library. When

I use the TSS_Library in MQX project, no button is detected and TSS1_fCallBack0 is never called. If I use the TSS_Library, with same configuration, in bareboard project, the buttons work fine.

How I configure TSS_Library in MQX-Lite project?

Thanks.

Hi,

What else should I do to fix this?

Hello Vinicius:

A time ago I created a MQX-Lite project with TSS Library and the touch slider was not working properly. What I did is to reduce the SysTick timer period to 500 us (Component MQXLite -> Inherited TimerUnit_LDD -> Counter restart -> Period).

I am not MQX expert, so I don't know all the implications of this change, but at least it worked for my application.

Regards!

Hi Jorge,

Thanks for the tip, but my touch keys are not working properly yet. I modified the period, but nothing changed.

When I use TSS Library with MQX-Lite project, the interrupt occurs always that I call TSS Task() and each bit of the Faults Register is setted: Charge Timeout, Small Capacitor, Data Corruption, Small Trigger Period and NoiseMode.

Regards,

I am using only a task in the MQX-project, with one loop where I call TSS_Task().

Hi soledad,

I read the threads and I followed the tips, but the touch buttons don't work yet.

If I use the same program without the MQX-Lite, TSS Library works well. Could be because of the call time of the MQX task?

Have a great day,

Vinicius
