Nice project

The Raspberry Pi Pico's features seem pretty impressive

RP2040 has good performance and is very powerful among M0 cores.

Aspberry Pi Pico also has a magical "programmable interface", I wonder if the OP has ever used it.

I don't know what it means

Programmable IO, state machine and fifo can be connected to IO port, which can be used for high-speed IO input/output operation without CPU participation, and can be used to complete some functions that can only be set by PFGA. This is my understanding, that is, universal interface, uart, SPI, I2C can all be used.

It seems to be similar to the Flex IO of some NXP MCU models, such as high-speed pulse acquisition. I wonder if the logic analyzer you recommend uses this function.

I haven't studied it carefully yet, but it does have this function and the dual-core is also very good.

I am looking forward to some dual-core reviews from the host.

In fact, there are already quite a few on the English forum

I really want to learn state machines, but I don’t know how to play them

Is this project a complete open source project? Is there any relevant website information?

Raspberry Pi Pico的功能看來是蠻牛逼的 !

I bought a Raspberry Pi 4B 2G version, but unfortunately I was so busy that it was covered in dust after I bought it. And the price was reduced by more than half later.

Now Raspberry Pi is a financial product

I have already lost money, what is the point of managing my wealth? I bought it for more than 1,000 yuan, but now it is only sold for 360 yuan

Isn't that what financial management is all about?
