XIAO RP2040

[Amrat]

As XIAO RP2040 is Arduino compatible. If to program with Flowcode, which device to select ? As no XIAO RP2040 in device select list.

Please advise.

Thanks in advance.

Hi

Just a guess but as the XIAO uses the RP2040 chip then selecting Pico > Misc > Raspberry_Pi_RP2040 might be a good start.

Thanks chipfrey27

But pin ID on XIAO RP2040 and Raspberry_Pi_RP2040 not the same !!
How to know which pin on XIAO RP2040 corespond to Raspberry_Pi_RP2040 pin ?

Thanks

Hi

From what I can see the XIAO uses the RP2040 chip but is packaged smaller meaning not all of the RP2040 pins are available, but these pins are "standardised".

By that I mean if you take a look at a XIAO pinout you will see that the pins used correspond to the RP2040 and therefore also to Flowcode.

If you look at the top left you will see P26 (which is also both an analogue input and digital I/O pin) and if you look at the RP2040 you will see that P26 corresponds to GPIO26/ADC0. Same goes for P27-29 on the XIAO, they correspond to GPIO27-29 / ADC1-3. The grey XIAO "P" numbers correspond with the RP2040 "GPIO" numbers.

In Flowcode, if you look at View > Target you will see an image of the RP2040 and the associated pin numbers which correspond to the above. If you "hover" over a pin Flowcode will tell you it's designation. Using P26 as an example (which is GPIO26) hovering over this pin shows that Flowcode calls it PORTA.26.

If you wanted to connect say an LED to this pin, in FC you would select PORTA.26

Hope this helps.

Dear chipfryer27,

Thanks for detail and very clear reply.

Thanks again
