Need Help in Selecting an MCU Board for a Roadtest

Back in 2018, I have roadtested Infineon XMC 1100. Looking at the table and recommended MCU specification, I could suggest this one.

But, as you have already decided, RPI-Pico, that is also impressive.

I wanted to report back to you as soon as I heard back from the sponsor. I took your ideas and suggestions to the sponsor to get their feedback.

Their preference is the Raspberry Pi Pico.

Now, the focus on the roadtest is the 2 driver boards they make (BridgeSwitch). One is a 30W and the other is 70W.

But we are throwing in a Fan motor. Actually an entire floor fan. I have one right next to me desk in our office and its a decent size.

And of course, the Pi Pico will be included in the roadtest kit.

I am hoping to launch this roadtest this week.

Thanks.

I am currently busy so I will look at this tomorow but first thing which is hard to comply is combination Cortex-M0 and 96 MHz clock. Very few MCUs with Cortex-M0 cores has so fast internal clock but for example in a Cortex-M4 category there are plenty of them. I will look at this tomorow for more detials and some reccomendation.

It looks like a great kit.

I'm partial to Cypress PSoC which is now Infineon, but whatever IDE fits the available software best is the obvious choice. I don't think there any plans to merge DAVE with PSoC Creator or Modus Toolbox.

The fan motor control library is targeted for Infineon, in this code here:

It looks like XMC1300 part, and to save people needing to port too much code (otherwise there's a learning curve for PWM, ADC etc for whatever microcontroller is selected, rather than focus on the motor design kits), maybe the same part, or very similar part could be used for the microcontroller board.

This microcontroller board looks suitable:

But probably the sponsor should be consulted just to confirm if they can recommend this one or not.

O would guess that more members are likely to be familiar with NXP over Renesas. However, I'm sure everyone has their own preferred microcontroller family.

I followed one of the links for the Reference Design Kit and the manufacturer seem to provide some sample code for Cypress PSoC - https://www.power.com/design-support/downloads/bridgeswitch-code-library-fault-status-communication-interface
