Good night,

I have a problem with my dsPIC33.
I when I turn on the dsPIC33 short time he turns off and then on again. And is always be connect and disconnect yourself. What can be?

hi After exploring the best forum I found this post. Joint now made a program in this post. http://www.matrixtsl.com/mmforums/viewtopic.php?f=29&t=8827&p=27054&hilit=SPI+Memory+Routines#p27054 I leave attached the program I've been to analyze the signals of the SPI. And chegei the conclusion that I ...

Hi
Was experiencing the file and did not work.
I have to put a resistance ... or something?
The rest of the EEPROM pin is necessary to connect?
Best Regards

Hello, The CAL_SPI is responsible for all low level SPI functionality. The SPI Master component has the CAL_SPI component built in but also provides some extra functionality in the form of macros and properties for the SPI E-block EB013 and Console data in the Flowcode simulation. Hello Can you tel...

Hello I'm trying to use an EEPROM 25AA1024. I got an example here in the forum. http://www.matrixtsl.com/mmforums/viewtopic.php?f=46&t=15031&hilit=25aa1024 But I am not able to get to work. The value of EEPROM shot is always 255. I ask for help to solve this problem. I leave my connections to my dsP...

Thank's

I have a Flowcode file to test. If you have a problem I say something.
Now only a curiosity, what's the difference between master and cal_spi spi?

Best Regards

Thanks for the reply

I have more questions, if you can help me grateful.
For SPI communication have the pin MOSI, MISO, SCK and CS right?
In the component properties not appear CS pin why?
What is the solution?

Origado

Hi

I'm trying to use the SPI function with my DSpic33EP256MU806.
I am beginner in electronica, I hope you can help me.
1º What the pins for the use of SPI communication (been to see the datasheet but not meeting the four channels SPI)


Best Regards

Hello,
No one can help me?
I am in need to solve this problem.
Always gives me 255 in variable.
Help me please

hello Benj
The problem is solved.
The CS3 was connected to the G9 pin and did not work, I moved to another pin and longer works. Not what was the reason for it does not work.

Thanks for the help

Best Regards

hi
I'm having trouble in it.
Always gives me 255.

I ask you to help me as fast as possible.

I'm desperate.

Best Regardshi

hi

Yes I apologize

I leave my program

I leave the pins lcd I'm connect

I leave the result that gives me in practice

Best Regards

Hey

I am not able to get this component working. They could do a sample program?

Best Regards

Hello,

I am using an DSpic33EP256MU806 but I am not able to use this component.
In the simulation gives perfectly. When I go to the chip it always displays the value 255.

I leave the program

Best Regards

Hello,

I bought this lcd

http://www.ebay.co.uk/itm/192x64-Graphi ... 43c14da9fd

But the pixels 124-192 do not work.
Know what can be?
And how to solve?

Best Regards

Good afternoon,

Any other opinion? I am desperate.
Does the configuration of DSPIC or perhaps viewing program records?
Attached leave the system I am using
Can I get help?

Hello
The file does not work. He just writes a record of each probe

It still says that the file I provided hasn't been downloaded yet so how have you been able to test it? edit: I just downloaded the file I provided and it instantly says it's been downloaded 1 time. I just wanted to make sure the information was accurate. In his commentary is a file. I test this fi...

good Morning

It does not work. Gives the same error

Any more suggestions?

greetings

Hello

I'm back to my project.
But still no progress.
I leave the record of my memory card.
490 490 records in practically the value gets spoiled.
Does not detect a change lines.
What could it be?
File in Excel

greetings

It looks like you pull the chip select low. send out a 0 to perfrom a read, then read a byte to collect the data from the register. Then raise the chip select to finish the transaction.

This might help.

Very good information
helped a lot
Thanks

Good night

Yes, you're right.
I apologize
Then leave the equipment

Thank you

Good night
I'm starting to study the SPI function. I found this table in the datasheet that will work.
My doubt is, how do I read the address 00h?

So if I have a dsPIC33 clocked at 4 MHz, and a prescale of osc / 4.
I'll take 500 kbits per second right?

Sounds right to me

4MHz / 2 / 4 = 500KHz.

Thanks for the explanation
Very good explanation

Hello, The SPI prescale is a division of the master instruction clock. So say the oscillator is running at 4MHz. PIC 8-Bit & dsPIC30 = Instruction clock = Osc / 4 = 1MHz PIC24 / dsPIC33 = Instruction clock = Osc / 2 = 2MHz AVR = Instruction clock = Osc = 4MHz So an 8-bit PIC with an Osc speed of 4M...
