XC8 Compilers - Discussion

[Manuel]

I Just checked the PICC side to be honest.

Can you share the "corrupted" file to ... check ?

or share the project so that can try same checking...

take care

Hi,

I have attached the AVR ATTiny412 project.
The source file is simple generated file.

[Manuel]

It get compiled with just one warning on Xide 6.20.

There should be some issue on your side i think.


take care,
X!

Hi,

I installed version 6.20 MPLABX.
Getting this error below:
Keep getting
note: Please reinstall the compiler

Could it be because files are not patched properly.
Could you please reply with steps required to patch properly.

Check Reply #141.

.... "the renamed file can stay in the same directly" before apply the "final solution".

take care,

Functional safety v2.49 released.

Functional safety v2.49 released.

Xo!

Has patch method？

[Manuel]

The TOP is perfecly working...

X!

[Manuel]

Updated to v2.50.

Xo!

[Mr. Spock]

Just wondering why people still use PIC 8 bits when you can get an ARM Cortex-M0  PY32F002A (SSOP20) from PUYA for US$0.075

[Manuel]

I understand your point of view, but consider that many application just accept industrial level product.

Anyhow, the PY32L020 is quite nice, but missing some peripheral.

take care,
X!

[patchjack]

I Request XC8 Functional Safety Compiler Evaluation License. For a 15-day evaluation license.
Add this license to the License path folder C:\ProgramData\Microchip\xclm\license.
2.46 and 2.49 generate exactly the same object code.
2.49 is Functional Safety Compiler. 2.50 is the latest version. The generated object code is different from the first two. The generated object code is smaller.
I no longer pursue the feature safety version. Because it just has one more functional safety certificate.
Attached is a detailed comparison.

hi

in the last version of Proteus, 8.17SP4, I open the sample project: DHT22 Low Cost Humidity Sensor & PIC18
and I try the last xc8 compiler 2.50 in various optimization levels by applying the Top patch or the xclm-hack.exe or the XC8Fs.lic from the last post of patchjack.

To make Proteus consistent with the xc8.exe optimization options, I modified the xc8.xml (C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\VSM Studio\compilers\xc8.xml) from this:
<OPTION NAME="--opt=" DESC="Optimization options" PARAM="CHOICE">
      <PARAM VALUE="1" DESC="Level 1"/>
      <PARAM VALUE="2" DESC="Level 2"/>
      <PARAM VALUE="3" DESC="Level 3"/>
      <PARAM VALUE="4" DESC="Level 4"/>
      <PARAM VALUE="5" DESC="Level 5"/>
      <PARAM VALUE="6" DESC="Level 6"/>
      <PARAM VALUE="7" DESC="Level 7"/>
      <PARAM VALUE="8" DESC="Level 8"/>
      <PARAM VALUE="9" DESC="Level 9"/>
      <PARAM VALUE="asm" DESC="Optimize asm code generated from C"/>
      <PARAM VALUE="asmfile" DESC="Optimize assembler files"/>
      <PARAM VALUE="speed" DESC="Favor code generation for speed over space"/>
      <PARAM VALUE="space" DESC="Favor code generation for space over speed"/>
      <PARAM VALUE="all" DESC="All"/>
      <PARAM VALUE="none" DESC="None"/>
      <PARAM VALUE="default" DESC="Default" DEFAULT="1"/>
    </OPTION>

to this:
<OPTION NAME="--opt=" DESC="Optimization options" PARAM="CHOICE">
      <PARAM VALUE="1" DESC="Level 1"/>
      <PARAM VALUE="2" DESC="Level 2"/>
      <PARAM VALUE="3" DESC="speed over space PRO"/>
      <PARAM VALUE="local" DESC="Localized optimizations"/>
      <PARAM VALUE="asmfile" DESC="Optimize assembler files"/>
      <PARAM VALUE="g" DESC="Favor code accurate debug"/>
      <PARAM VALUE="s" DESC="space over speed PRO"/>
      <PARAM VALUE="all" DESC="All the above"/>
      <PARAM VALUE="none" DESC="None of the above"/>
      <PARAM VALUE="default" DESC="Default" DEFAULT="2"/>
    </OPTION>

Each time, I changed the optimization parameter only in the linker (LD) tool, since I had first added the --opt option. In the compiler (CC) and assembler (ASM) tool you don't need to add the --opt option.

I got the following results:

Hi,
Does someone know the XC8 pic tutorial using the compiler in
command line mode without using the mplab ide.
