It depends on the nature of your code, and your data.

On TX, the supplied routines are fine, provided you ensure there is space before sending.
On RX, the supplied routines could result in the los ...

Thanks Ttelmah. I will go through the examples.

So are you suggesting I should implement my own buffer system instead of CCS provided one? Due to the issues it has?

Hi friends,

I just started doing a project with dspic 30F4013 and need to use its hardware UART.

In the wizard I can see these buffer options (RECEIVE_BUFFER,TRANSMIT_BUFFER) and it can be conf ...

Yes.

You can do the state machine in the interrupt, since though the code is large, it only ever handles one state.
However generally you don't do this in the interrupt, but in the main code. Tha ...

It's not going to be any more 'efficient' in terms of memory usage. Enough space is going to have to exist for the worst case somewhere, and dynamic allocation will mean more code, and more time.
Obv ...

Hi Guys,
I'm trying to read some data from uart.
the exact length of received data is not fixed and end of data is identified by a delimiter.

I'm just wondering is there any memory efficient way ...

Display the characters....

that is what i thought. I was looking for more lazy way Very Happy

thanks Ttelmah

Hi
sorry for reviving this old post. but my question is related to this.
@PCM programmer,

How can we know which chip is used in the lcd module we have?

I have some 16x2 lcd modules but their c ...

Problem is that you haven't got a variable called rcv, just a union declaration for it. Extern applies to a variable declaration. You need a variable name in the extern declaration. I'd suggest typede ...

hi guys;

I'm trying to define a union in main.c file and use it on another c file in Same project using extern key word,
but compiler fail to compile.

Ttelmah

it worked
many thanks Very Happy

aha
That means I should declare all variables by signed or unsigned ? Right?
Thanks.

Hi
I'm working on a battery charger circuit based on 12F683. I have encountered a strange issue. My compiler version is 4.084.

Problem is in the function charge_end().

Program is written such t ...

If you select a lower count value for timer1, the frequency goes up, and the available resolution goes down. So with 127 selected, you get 511 as the maximum value (0 to 511 = 512 values - 9bit reso ...
