Building firmware

[ErnestasRaitelaitis]

Hello people.
First of all I want to say that I'm new to GRBL and everything what it depends on.
But I have some knowledge building and uploading marlin FW.

I have read all issues of read.me files (which I found)

First I tried to build firmware with VS Code and platformio (it didn't go at all as I could not find any info on how to create platformio.ini file), then I have read LPC176x read.me and there was note about MCUExpress, so I have downloaded it.

Pulled the source: git clone --recurse-submodules https://github.com/grblHAL/LPC176x.git

Opened folder in MCUExppress, changed my_machine.h file
#define BOARD_BTT_SKR_14_TURBO
#define TRINAMIC_ENABLE 2209
#define SDCARD_ENABLE 1

everything else left commented.
tried to build got firmware.bin file (250KB)

flashed to board, and looks like in firmware missing some stuff.

Maybe can anybody pinpoint me in the right direction what I'm doing wrong and how to fix it?
Firmware.map.txt

Thank you for your time and effort

What is missing?

Thanks again.

And one more to annoy you (hopefully not very much).
My laser module pwm is 5V based, and I found that servo pin 2.0 is that I need.

So now I'm a bit puzzled. in board map file there are defines:

LPC176x/src/boards/btt_skr_1.4_turbo_map.h

Lines 156 to 166 in f5f52df

	#if DRIVER_SPINDLE_ENABLE & SPINDLE_PWM
	#ifdef SPINDLE_PWM_PIN_2_4
	#define SPINDLE_PWM_CHANNEL PWM1_CH5 // MOSFET3 (P2.4)
	#else
	#define SPINDLE_PWM_CHANNEL PWM1_CH6 // BED MOSFET (P2.5)
	#endif
	#define SPINDLE_PWM_USE_PRIMARY_PIN false
	#define SPINDLE_PWM_USE_SECONDARY_PIN true
	#define SPINDLE_PWM_PORT AUXOUTPUT3_PORT
	#define SPINDLE_PWM_PIN AUXOUTPUT3_PIN
	#endif

As I understand, that all redefines should be done in my_machine.h file.
so how do I redefine pwm pin?
I made some digging through the code and found:
https://github.com/.../f5f52df4.../src/grbl-lpc/pwm_driver.c
in this file there is PWM1_CH5, and it links to P2.4, so I assume, that changing:
this:
#define SPINDLE_PWM_CHANNEL PWM1_CH5
to this:
#define SPINDLE_PWM_CHANNEL PWM1_CH1
should do the trick...

but then the question: Should I add "#define SPINDLE_PWM_PIN_2_4" to my_machine.h? Then what this define should be equal to?
Or this is done in a different manner?

[terjeio]

Just change #define SPINDLE_PWM_CHANNEL PWM1_CH6 to #define SPINDLE_PWM_CHANNEL PWM1_CH1.

Thanks again.
I have changed this define, in board h file for now, just to try things.
Build firware uploaded it.
Called $rst command. Turned off and on machine.

Then with multimeter tried to look which pwm pin will get trigered, and it didnt worked... the same 2.4 is trigered, when i turn laser on, the servo pin stays always about 3V. What do I'm missing?

[terjeio]

When I test with a SKR v1.3 board the change works (I do not have a v1.4 board).

the same 2.4 is trigered

Did you add #define SPINDLE_PWM_PIN_2_4 somewhere?

When looking at the code I see that the 2.4 code is greyed out, which means that it is not used:

You see the same? You may have to rebuild the index first, right click on the project root in the Project Explorer and select Index >Rebuild.

[ErnestasRaitelaitis]

OMG, that was my fail :D
I had old code which worked. And wanted to start fresh, so I created another project, updated in new project, but firmware file I send was from old project. And I made it several times... :)

Now Everything is fine.
Man, that's why you have a black tuxedo...

Thank you very much!!!
