Matrix user forums

Thanks Martin that worked.

Hi Guys

I want to configure a PIC16C770 but when I go to the chip configuration I get a message (from the Matrix pic micro programmer) unrecognized chip on command line <PIC16C770> I have tried with other PIC16C and 12C but the problem is the same, how can I solve this issue?

Best regards
Xavier

Cab anyone help?

Sure thing Benj

All the best

Hi guys I'm using timer 0 in main then timer 2 in a macro but this timer dose not go to the interrupt, could you tell me if I have something wrong in my settings ? Timer 0 set to internal timer, clock speed 19660800, oscillator set on HS, watchdog timer off, power up timer on. Need to say that this ...

Well I thought that I followed all the steps to the letter but it seems that I did a boo boo LOL

Cool thanks Martin I'll give it a go, may take me a while though LOL will get back to you no mater what.

Best regards

Hi Martin Sorry for being away for so long but had a bad case of chemotherapy but all is well now so i'm :D again (till the next bad one) any ways I got all the code working just like I wanted it to and i must say that I'm quite pleased with it, however I have come up against an obstacle and I have ...

Hi Martin

Well got it working, sending numbers like I want it to now will I be able to get it to work in the programme the same way is another matter. Will keep you posted.

Hi Martin

Been having Internet problems on my end for the best part of the day so I'm not sure if you received the email that I sent you, could you please confirm. Also could you post the two FC files that you used for testing as I think that I mesed things up on my side.

All the best Xavier

Hi Martin

It's sending and receiving but I do have an issue, if I send only once I do not receive but if I do a continuous send then I receive the data. I think that I mesed up either the TX or thr RX flow chart. Got your PM and am going to send you all relative info.

Best regards

Hi Martin Haven't been feeling great today so have done very little but I do have coms between the two pic's I sent a string and it came up on the LCD so that is one thing out of the way. Now I just need to be able to send a number. How can I post a schematic? I wanted to post a jpg yesterday but I ...

Thanks Martin I will look into that tomorrow, I'm starting to make stupid mistakes now so will give it a rest.

All the best and thanks for the help
Xavier

Hi Martin Well I'm at a complete loss now Martin. I decided to go back to the basics that worked before but now I get this when sending a string. Ho I just found out that I can't post a jpg OK then when I press the send button the displayed "RS232" comes out looking like this #$÷×/"^:€*!/ and more c...

Hi Martin

I got no results with the 25, tried sending 57 and got no results either. My LED does not flash this should mean that I do not go out of the loop. That is if I got the FC correct.

Xavier

Hi Martin I'm going to have to study all that you have said very carefully (very interesting stuff) in the meantime I was having a bit of fun trying out some stuff on my own, but alas the results are poor. Here are the two files TX and RX so that you can see what I've been trying to do. I don't use ...

I noticed that we both gave our new file the same name, could you rename it to RS232_RX V1.3 (the one that I sent you)

Xavier

Hi Martin

I was just going to send you the FC file with some questions in it. Actually I will send it to you, never know what can come out of it. I'm now going to have a look at the new one that you posted. Thanks for all the help Martin much appreciated.

Xavier

Thanks Martin

I will have a look at it in the morning he he almost morning here. Will be sure to let you know if it will do the job or not.

Hi Martin The oscillator speed is my fault, what I did instead of sending you a huge file I copied the part that's giving me the problem and I forgot to change the settings for the oscillator speed in project options. Yes I would like to be able to send a number from 0 to 220 so I could be sending 7...

Ok well here are the two files one for the tx and the other is the rx

Hi guy's I've been looking on the forum but don't seem to find what I'm looking for. I would like to send numbers from 0 to 220 from one pic 16f690 to another pic16f690 using the Rs232, I can send a string no problem but numbers either give me 0 or 255 now how difficult can it be to send the number ...

Thank you so much Kenrix2 you have been a great help, l have been taking a good hard look at the way that you work with interrupts and timing and have come to the conclusion that I have to find a tutorial on the subject. Any suggestions?

All the very best to you
Xavier

Thanks Kenrix2 I had thought that perhaps the only way to do it was with a lookup table. Could you tell me why when I use an interrupt of 100, 000 the LCD stops working? Using a round number as an interrupt becomes manageable, I made up a formula for it using the interrupt frequency/1000, 000 I then...

Managed to get the file.

Hope that this will make more sense.
