Program rests

[antonadc]

Hello ME team

I am using a pic32mx130f64b chip reconfigured the rx and tx pins to port b14 and 15. all works great . I wrote the following simple routine to see how it works. At 10 000 the routine resets. Why is that so. Any help will be appreciated. I have even tried it with longword..The crystal I am using is a 20mhz and configured it to 50Mhz divide by 4 multiply 5 divide2

Code: Select all

program Led_Blinking

 dim hold as uint64
 dim holdstr as string[20]

main:
  JTAGEN_bit = 0                     ' Disable JTAG
  ansela=0
  anselb=0
  Unlock_IOLOCK()
  PPS_Mapping(_RPB15, _OUTPUT, _U1TX)' Sets pin PORTB.B2 to be Output and maps UART1 Transmit to it
  PPS_Mapping(_RPB14, _INPUT, _U1RX) ' Sets pin PORTB.B3 to be Input and maps UART1 Receive to it
  Lock_IOLOCK()
  TRISA = 0                          ' Initialize PORTA as output
  TRISB = %0100000000000000          ' Initialize PORTB.b14 as input
  UART1_Init(115200)
  LATA = 0                           ' Set PORTA to zero
  hold = 0
'-------------------------------------------------------------------------------
  while TRUE
    hold=hold+1
    LATA = not PORTA                 ' Invert PORTA value
    Delay_ms(100)
    UART1_Write_Text("Hello World = ")
    uint64tostrwithzeros(hold,holdstr)
    UART1_Write_Text(holdstr)
    UART1_Write_Text(" 100ms")
    UART1_Write(13)
    UART1_Write(10)
  wend
'-------------------------------------------------------------------------------
end.

Thanks
