Hi Team,
We are using the keypad interface to the processor GPIO’s pins below mentioned details. We are facing when key is pressed the GPIO4_IO_24 is low but should be high incase if we remove the debouncing circuit (40.2k and 0.1uF) so GOPI4_IO_24 pin will be high state once you press key. Could you please confirm can we have debouncing circuit if need please suggest the RC value.
| Sl no | Display Board | Processor Interface pin name |
|---|---|---|
| 1 | UP | GPIO4_IO_24 |
| 2 | DOWN | GPIO4_IO_25 |
| 3 | OK | GPIO4_IO_26 |
| 4 | HOME | GPIO4_IO_21 |
| 5 | ESC | GPIO1_IO11 |
