Hello! Sorry for the late reply. I have attached a C file and a hex file of a 18F4520 program that I have used in the past. The program reads inputs from B0 and B1, and increments a 7-seg display accordingly, its basically just the MikroE program slightly modified. This program ran fine before, and ...

Hi, I have an EasyPIC5 board which has begun to act strange recently. I have been trying to program a 16f877, but I keep running into issues. It programs successfully according to PICFLASH, but it wont physically do anything. I have tried this with known working code and it seems as if there is some...

If you mean the one with the flashing LEDS that one seemed to work correctly.

Im not sure which code you mean? Did you send an email or PM or something?


Thanks

Anyone?

It looks like you have a 1 second delay after you 1 byte of the uart which wouldkeep you from receiving any other characters. I'll try to play with your code again later. Im a little confused as to what your saying? Im not sure which delay your talking about. I ended up getting my USB to RS232 conv...

Thanks for the replies! Il be trying this soon, I ended up installing Ubuntu on my desktop forgetting that I needed it for the UART terminal! I ended up ordering a USB to RS232 connector, so I will let you guys know how I make out soon.

This is killing me, I cant get anywhere. Ive hooked the receiver to the Terminal and I get no response what so ever. I send the values separately and together and I get no response. I figured I would clear the RCREG at the end of the loop, but im just kinda shooting from the hip. Any other insight i...

This did in fact end up working, im going to try and see if I can figure anything out with my actual code. Il post the results.



Thanks again!

I've been messing around with this some more, and havent gotten any where. the only thing i can think is that my device flags are not set right. What I have set is: WDT_OFF MCLRE_OFF INTOSC_OSC_NOCLKOUT Im not sure if Im missing anything, or if I shouldnt have one of these checked off. Thanks

Thank you very much, I really appreciate all of your help!!

The loopback works, if I send and A I get back an A, but if I send an "a" I get "aaaaaaaa" back.

Also the light wont flash if "A" is sent?


Thanks for your time!!

Thats what I meant, came out wrong... :oops: Ive been messing with this all morning and im still in the same place. I only used one 1s delay, because I dont want a delay in between the port changes. Now Im getting warmer, before I couldnt get the ports to initialize correctly, now PORTA is high and ...

The basic idea is to have 8bits high at all times, and then the status of PORTA that is transmitted will kind of be an inverted binary number eg- 1110 for 1 1101 for 2 1100 for 3 etc etc So by saying PORTA = 1 that only sets PORTA.F1 to 1? So the default output of PORTA would be 0001? Thank you for ...

Man, I never noticed that. They helped out greatly on the transmitter it works perfect.

Tx transmits: 49 49 65 PORTA 66 35

The receiver although, not as lucky. Is it necessary to call Usart_Data_ready before each number? Or am I sending those as one combined number?


Thanks again.
