Yes Ttelmah, I did change the fuse to HS and made the alteration that you said regarding the UART. But the software was asking for PIN setting(PPS). and once that was chosen it is working now. Once a ... |

The actual problem was the crystal in the board. It is marked 8Mhz but it
produces about 10.21 or something like that Mhz. Used the internal oscillator and everything is fine.
I would like to thank ... |

Thanks Ttelmah.
I changed all those things you said. and moved PIN_B1 to some other pin and it worked thanks for your help once again. |

Thanks temtronic for your reply.
The spi device is 23lc1024 and it is mode 0.
actually it was working when i had the spi device in default pins namely PIN_B5 SDI1,
PIN_B4 SCK1,
PIN_C7 SDO1.

Ttelmah you nailed it. The return value from the function did convert the value to BCD2BIN.
Thanks for pointing it out. |

I figured it out.
for some reason for loop is not working. i try a while loop and it works just

Some one can please clarify.
thanks |
