Hi ,

     I am using CY8C4014 SXI -421 SOIC 16 device for capacities touch application.

two key is used in this project. one is to On/OFF the relay and another one is to increase/ decreases the PWM.

during the testing i found the controller is not working as expected. so i just made one simple 4 LED blinking code. that also some time its working some time only one LED is working.

i think there is some Power on reset problem.

could you please help me to solve this problem. i have attached my code here.

thank you.

Hello Hari,

Thanks problem is resolved.

Actually the internal actually the internal reset pin was used as a output pin(P1.6). after changing the PIN drive mode its working.

Thanks for your support.

Hello RARA_2227736

The code that is shared is straightforward and will work under normal operating conditions. Please share the schematic and layout of the board that you are using so that we can verify the design.

You can refer to PSoC 4 Hardware design considerations for recommendation on decoupling capacitor on power lines and reset (XRES) pin. Please make sure that this is being followed in the design.

Thanks and regards

Hari

Dear Hari,

Thanks for your update,

Please find the schematic attached.

I am not getting core operation voltage at VCC pin. Its zero voltage. Its connected with 0.1uF capacitor.

Thank you

Hello RARA_2227736

You must be observing regulated digital voltage of 1.8V (±5%). Please verify the supply in the layout and make sure that the decoupling capacitors are present close to the IC.

Thanks and regards
