| CLC problem |
 Posted: Wed Feb 22, 2023 3:44 am |
 |
|
I used MPLAB X IDE GUI. I copied the resulting code and added it with getenv(). But when I compile I get an error. The error I get is: Expecting an identifier Bad SFR name.
CCS C 5.114
| Code: |
#include <18F57Q43.h>
#use delay(internal=64MHz)
#byte CLCSELECT = getenv("SFR:CLCSELECT")
#byte CLCnPOL = getenv("SFR:CLCnPOL")
#byte CLCnSEL0 = getenv("SFR:CLCnSEL0")
#byte CLCnSEL1 = getenv("SFR:CLCnSEL1")
#byte CLCnSEL2 = getenv("SFR:CLCnSEL2")
#byte CLCnSEL3 = getenv("SFR:CLCnSEL3")
#byte CLCnGLS0 = getenv("SFR:CLCnGLS0")
#byte CLCnGLS1 = getenv("SFR:CLCnGLS1")
#byte CLCnGLS2 = getenv("SFR:CLCnGLS2")
#byte CLCnGLS3 = getenv("SFR:CLCnGLS3")
#byte CLCDATA = getenv("SFR:CLCDATA")
#byte CLCnCON = getenv("SFR:CLC1CON")
void CLC1_Initialize(void) // CLCIN0=0,CLCIN1=0,CLCIN2=1 CLCOUT(F0) = 0 else = 1
{
// Set the CLC1 to the options selected in the User Interface
// SLCT 0;
CLCSELECT = 0x00;
// G1POL not_inverted; G2POL not_inverted; G3POL not_inverted; G4POL inverted; POL not_inverted;
CLCnPOL = 0x08;
// D1S CLCIN0 (CLCIN0PPS);
CLCnSEL0 = 0x00;
// D2S CLCIN1 (CLCIN1PPS);
CLCnSEL1 = 0x01;

CLCnSEL2 = 0x02;
// D4S CLCIN0 (CLCIN0PPS);
CLCnSEL3 = 0x00;
// G1D3N disabled; G1D2N disabled; G1D4N disabled; G1D1T disabled; G1D3T disabled; G1D2T disabled; G1D4T disabled; G1D1N enabled;

// CLC1OUT 0;

// EN enabled; INTN disabled; INTP disabled; MODE 4-input AND;
CLCnCON = 0x82;
}
void main(void)
{
CLC1_Initialize();
while(TRUE)
{
}

It looks as if getenv doesn't know all the CLC register names. Report it
to CCS. Meantime the automatic file generator (in tools), happily generates
an include file for CLC as:

I sent an email to CCS. I added what you did to the code. There was no problem in compiling. But I didn't see any movement at the exit.

You seem to be trying to setup a 3 input OR gate. (AND, with all the
inputs inverted, using three physical inputs, and one pin wired high).
You don't show the PPS setups for CLCIN0, CLCIN1 or CLCIN2.
Remember you have to enable the TRIS on the pin used as the CLC
output. By default all pins are set as inputs. |

output_drive(PIN_F0);
Otherwise it is set as an input.
Also B0 is used as an input, but you have it set as an output:
set_tris_b(0x00);
Needs to be:
set_tris_b(0x01); |

I added these 2 codes. But again it didn't work.
| Code: |
#use FAST_IO(f)
set_tris_f(0x00); |
I typed wrong. PIN_D0 , B0 is not used.

Er. You said:
CLCIN2 PIN_B0
But you have this pin set as an output. |

just a comment..
be REAL CAREFUL about using FAST_IO() and SET_TRIS...() !!
If you edit code wrongly, you'll run into problems !!
For now, stay with STANDARD_IO() and let the compiler handle it. |

However, since he is manually programming the CLC, not using CCS
functions, he will have to manually program the TRIS for this. |

Now I rearranged it.
I used mplab GUI.
Inputs/Outputs;
CLCIN0 = A0
CLCIN1 = A1
CLCIN2 = B0
CLCOUT = F0
No error occurs when I compile. However, it does not work correctly. It works when I do the same operations with the CCS C compiler. Where is the mistake?

What you post as the MPLAB version, does not show PIN_SELECT entries.
The CCS version does.
You need these. The gate will not work without these. |

So how do I do this? Do I add the same lines?

Yes.
Or just use the CCS code version.
Why if you are using the CCS compiler, would you want to directly write
the registers?. |

The GUI is much easier to use. By the way, I did what you said and it worked. Thank you very much. Yes it works with CCS. Actually, I can go on. But I want to solve this problem too. It's not that hard after all. But not working is very frustrating..
