EK-TM4C1294XL and BOOSTXL-K350QVG-S1

Hello Ivan,

You can check the booster pack compatibility using the following cloud resource

Hello Amit,

Thank you very much. The checker is amazing. A couple of questions. 

For my configuration it says that pin #40 on BP #1 has no PWM function while the User Guide for Launchpad says it has. Which one is correct?

For TOUCH XN and TOUCH YN signals there is no AIN function on corresponding PINs. How could it be handled?

Ivan

Hello Ivan,

There are 2 booster pack headers BP1 and BP2 on the EK-TM4C1294XL. Which one are you referring to?

Hello Amit,

Please sorry for the late reply. Bpchecker indicates the same discrepancies on both boosterpacks. But let's talk about BP1.

Hello Ivan

And what about BP1?

The question is:

For TOUCH XN and TOUCH YN signals on the BoosterPack itself there is no AIN function on corresponding PINs on the BoosterPack interface. How could it be handled? Should I reroute somehow IO of microcontroller pins which are able to work as AI to the corresponding pins of the BP interface?

Ivan

Hello Ivan,

That is not needed. XP and YP are analog Pin.

To measure X position, set XP as digital high, XN as GND and YN as tristate. When the finger touches the screen, the measure of the voltage on YP to get the distance from XP.

To measure Y position, set YP as digital high, YN as GND and XN as tristate. When the finger touches the screen, the measure of the voltage on XP to get the distance from YP.
