Flowcode Support Board

not able to complete compile to target. looks like fc is not finding pico-sdk path, however it matches location. also looks like it cant execute a cmake command. any suggestions to fix? some of the downloads in the fc installation are dated/not available or archived. I followed as close as possible incl setting path during install.

Hi.
I have just installed the Pico Toolchain and RP2040 compiles for me.
Link for visual studio
I downloaded Build Tools for Visual Studio 2019 (version 16.11)
Hint, use ctrl f and search for build tools
Link for CMake
You might be best uninstalling, then reinstalling using the above links.
I know with the ESP, if later versions are used than suggested within the install guide, then compiling does fail.
I can't see the Pico toolchain being any different.

If ESP32 is already installed and working, you will only need to install Build tools (I installed v16.11) and the PICO SDK.

Martin, uninstalled--->reinstalled with links you provided. seems to have worked (small program compiled and downloaded). something in vs build tools or cmake I guess. Thank you

FC/Matrix- Another thing I can't figure out.

First program loads fine after power up with bootsel held down. compile to target or drag/drop of uf2 both operate fine for first program file load.

How are subsequent program files loaded (without power cycle + boolsel)?
compile to c, hex and to target disconnect the rp2040 drive image from the PC so not possible to drag/drop uf2 file. Is power cycle + bootsel the only way to load a project?
looks like compile to c will not generate a new uf2, but compile to hex & target will.

I am evaluating various hardware platforms for our product development and it feels like there should be more documentation about how FC software interfaces with specific platforms (ESP32, rp2040 specifically).

That's great, I'm glad you are now up and running.
Thanks for letting us know.
As far as I'm aware, in order to program the Pico you have to have USB disconnected, hold the BOOTSEL button down while reconnecting the USB lead.
It should then create a virtual drive at that point for Flowcode to save the required files on.

Ok, thank you for confirming. I was looking to use it like a micropython main.py file. I see how it works now. Thank you!

Martin,

I don't want to constantly lean on you guys, but I don't know what to do with this error. I added in the ws2812 object to 3d panel. The command dout to pin16. Up to this point, fc will compile the project. Once a component is inserted to the flowchart, the compiler chokes on something to do with the nop's used in the timing. Only need to add the initialize component to get this. When I compared it against moodLightStrip2 example, and it doesn't look any different.

uc is rp2040 with wiznet w5100s-evb-pico. At first, I thought the nop count generated was too high, but throttling back the cpu clockspeed didn't do anything. here's the compiler message:

Hi.
We are looking into this and hopefully, a fix will be available as soon as possible.

A tip.
Connect a tactile switch from Run to GND.
When you want to program, do this in the following order.
Hold the new tactile switch down
hold BOOTSEL switch down.
Release the new tactile switch.
Release BOOTSEL switch.
If in program mode and you don't want the PICO to be in program mode, press and release the new tactile switch.

Hello,

RP2040 should now be working correctly with the latest version of the WS2811 component on the update system.

Many thanks for letting us know.
