Program uploaded in arduino uno runs but in esp8266 not run

i had done program for rummy card dealer which can distributes rummy card according to no of players and no of cards

i am using A4988,keypad,16x2 lcd and DC motor when i run it in arduino uno that runs fine but if i run it in esp32 or esp8266 it not run instead of run it returns Watchdog timer error

It does not sound like you have a problem with an Arduino Nano ESP32 and hence your topic has been moved to a more suitable location on the forum.

3

Sounds like your program is running into the ESP8266's watchdog. If your loop function is taking more than a few seconds to complete, you'll have to call yield(); yourself to keep the watchdog from barking.

4

But when I run it with Arduino uno I just uploaded this code it runs fine without calling yield(). for esp board I just yield() that's ok?

5

Yes. And the slightest research on your part would have revealed why that is.

Google yield esp8266.

Read.

Think.

Learn.

i happy to say this thank you for your valueable time, i feared out the issue i put just in keypad pin section Add D before pin number like
instead of (wrong for esp series board)
byte pin_rows[ROW_NUM] = {6, 7, 8, 9};
byte pin_column[COLUMN_NUM] = {10, 11, 12, 13};

correct for (esp series board)
byte pin_rows[ROW_NUM] = {D0, D1, D2, D3};
byte pin_column[COLUMN_NUM] = {D4, D5, D6, D7};
