Thanks for your comments . I am using version V8.
I would like to use the value in an EMA calculation (1-alhpia) as part of a filter.
It seems to work in my 8 bit version of the program.

Sir I am trying to use the fround command to limit a floating variable to 2 decimal places. It appears not to work in the simulation.

EMA_APHIA = 0.90

EMA_APHIA = fround (EMA_APHIA,2)

when I run the simulation I get 0.899999976------------lots more.
Does this command work in the simulation or ...

Hi QMESAR
Thank you my friend. I feel such a fool.
It works now
Thank you

I am having an issue compiling to HEX for pic chip 16f1615.
The system returns a syntax error
test_16f1615.c: main()
480: FCV_VOLTS_IN = 0;
^ (195) expression syntax
(908) exit status = 1
(908) exit status = 1
The failure is always on the first line of the program after a C code box defining ...

Hi Chipfryer27
Sorry for the delay I was building the circuit board to try out the program. I am pleased to say I only needed to add one line of C code to turn on the port for RA2 .
I placed this line after the component MARCO to enable the DAC output .
DAC1CON0= 0xB0 .
Next I have the component ...

I am using PIC16F1709 and I want to use pin RA2 as the DAC output.
Flowcode8 does not allow me to set the DAC o/p pin. Default port A0.
Looking at the form it appears it I set C code for DAC1CON0 = 10110000 (0XB0) this will enable pin RA2 and disable Pin AO.
My question is my code correct in the ...

I am new to flowcode and pic programming in general, however I must say that with flowcode I managed to do what I want with one exception,
For my program to work I used a string usb slave port, all I do is in one line write a string to set outputs and in the same scan read in all inputs.
It is ...

I managed to get usb slave working with a program I wrote in vb.
The problem is that once I successfully introduce the slave into my project all other routine in the main menu work in the panel but not in the chip.
I have tried calling a macro from the main menu.
I am trying to pulse an ...

Is there a way to change the input amplification gain of an analogue in port.
The problem I have is my source signal is only 0 to 1 volt.
I can do this by amplifying the signal with an op amp however if it can be done in the chip it will be more convenient.

If I read an integer from an analogue in, how can i send it to the host via usb,
I tried converting it to a string and send it across,
It comes out in 4 registers. For the love of me I cannot figure how to get these 4 values back to a decimal again.

I have studied the examples and just cannot get it right, am I correct in saying the first 3 bytes sent are stored in the macro.a,macro.b and macro,c variables.
Macro.a determines the subroutine to be performed
Therefore if I send 0,0,50
We will output the first routine, setting outputs according ...

Thks i will study it carefully
However once this data has been sent how in the flowcode macro do i analize this
if i could have an example of how to put on an output and read in an input say a analohue in

Can someone tell me if I am correct in analizing the following instruction
lRetVal = ECIO_Transmit(bDataOut(0), 3, nTxDataCnt, bDataIn(0), 32, nRxDataCnt, 500)
bDataOut(0) this is the number of the board
, 3, this is the macro 3 that will run ie the 3 condition in the service macro
The rest does not ...

Is there a white paper available for the VB example that can help me in understanding the Syntax required to successfully read the inputs and write to the outputs.
All I need to do now is how to read the variables into VB From the pic and write to the variables in the pic.

Thks i manage to compile the 3 byte example and send it to the pic.

if i put a slave usb component macro to flowcode, just 1 macro i get the following message, wheteher it is my flowcode ot he examples supplied.
