RP2040 ram and rom usage?

[Chadb]

Oh, and pin25 isn't defined in the PICO file. So I don't think that will work either. It would in the rp2040.

Hi Chad,
I now have this working (again)

The missing link is ...
Step 1
Add pico_multicore to target_link_libraries in CMakeLists.txt
C:\ProgramData\MatrixTSL\FlowcodeV10\FCD\PICO\batch

Code: Select all

target_link_libraries(flowcode pico_stdlib hardware_adc hardware_spi hardware_pwm hardware_i2c pico_multicore)

Step 2
In your project "Supplementary code" -> "Definitions" add the following (Ben: could probably go in the FCDs)

Code: Select all

#include "pico/multicore.h"

Step 3
Put the code that you want to run in the second core into a Flowcode macro, e.g. CORE2
Launch it from the following C code icon in the Main macro

Code: Select all

multicore_launch_core1(FCM_CORE2);

All done, delete any pre-existing build directory and recompile.

btw. (Using target Pi Pico) For the onboard LED you can use the following in a Calculation icon

Code: Select all

$PORTA.25 = 1

edit: Ah, and last but not least, be careful with using two cores, functions aren't necessarily thread safe

Hi Leigh

Huge thanks for this, works a treat.

With this extra power surely my world domination is a few steps closer

Best regards

That's great! I'll give it a whirl a little later.

Thanks,

Chad

*Edit: Works! Thank you.
