| Using Pin select and CLC's on Pic16F18346 |

Hi
I have been struggling in understanding in using the CLC functions with CCS compiler. I originally posted some code using PIC16F1619 but used the Microchips Code Configurator not the CCS internal CLC functions. I got it working using by assigning values directly to the CLC registers from code generated from Code Configurator with also including with using CCS #pin select definitions. This was with compiler version 5.052. I had to upgrade to the PIC16F18346 because I needed more code space. CCS v5.052 did not support PIC16F18346 so I use the device editor to add chip and got it to compile. I was not sure if I had done it right, but found the CLC selection and Timer 3 and Timer 5 as counters did not work. So I decided to upgrade the compiler to v5.074 $$$$  . To my surprise it still does not work.
The code posted below compiles with both versions modified v5.052 & v5.074, and works only with the generated code from Code Configurator code, not using CCS CLC functions.
Most CCS examples never show real schematic to code. I have tried to understand the use of CCS CLC functions based on schematic also below.
What am I doing wrong

This just test code.
The code above starts a motor rotating with attached encoders for 1 second CW then reverse direction CCW and displays timer counts.
Timers
T0 & T1 works shows counts
T3 & T5 does not work, these did work with PIC16F1619
| Code: |
#pin_select CLC1OUT = PIN_C5
#pin_select CLC2OUT = PIN_C0
#pin_select T3CKI = PIN_C5
#pin_select T5CKI = PIN_C0
#pin_select T0CKI = PIN_C5
#pin_select T1CKI = PIN_C0
|
I assigned both CLCXOUT pins to both sets of timers above, but also tried them using timer T3 & T5 separately, still does not count.
My overall objective is to understand how to use the CCS CLC functions with a real example.
The timers T3 & T5 is possibly a compiler issue?? But need to get it working with T3 & T5.
Schematic at link below:
[img] https://s29.postimg.org/bjke6nkfr/CLC_Example.png [/img]
Original Schematic used CLC1 RA3 & RC7. This code is using RC4 & RC7.
Sorry for long post and explanation.
Thanks in advance.

Can you post two source code programs:
1. A program done with direct register access, that works correctly.
2. An equivalent program done with CCS functions that doesn't work.
If you can do that, I can compare the .LST files and see what's missing
from the CCS functions and hopefully fix it for you.
Make these programs as short as possible, and don't put any commented
out code in them. In other words, I just want simple clean programs that
I can compile and look at.
Both programs should be for vs. 5.074.
The reason I want you to make two separate programs for me is that
I don't want to try to take apart your posted code by myself. It's better
if you do it, because you understand what you want in the programs. |

Have a look at this thread:
<http://www.ccsinfo.com/forum/viewtopic.php?t=56448>
Haven't checked whether your chip might have the same problem, but on this chip only the low 4 bits of the selection value was being written by the CCS function. As you will see CCS have acknowledged this and will fix in the next release. The CCS 'values' still work correctly, but only if written directly to the actual selection register for any one needing setting to a value above 15.
Most (all) of the last generation of CLC's only had 3 or 4 bits for the selection value. MicroChip's own configurator tool gives the same fault if you use an old version. |
