With my annual holiday coming up, I was trying to decide what tech to take. I normally take something to keep me amused if there's a rainy day. So I've put this together. It's a pair of Pico's back to back on breakout boards. One will be flashed to run Micropython, the other flashed to run BASIC. Nothing else needed as I'll have a laptop with me already.

 

 

The breakouts are really cheap and come from a company called Cytron.

#1 Hardware Problem? https://www.avrfreaks.net/forum/...

#2 Hardware Problem? Read AVR042.

#3 All grounds are not created equal

#4 Have you proved your chip is running at xxMHz?

#5 "If you think you need floating point to solve the problem then you don't understand the problem. If you really do need floating point then you have a problem you do not understand."

The double row sockets is a clever feature.

With the PIO units and the relatively large 256kB SRAM, I could see it being used for a nice little logic analyzer.

$4 Logic Analyzer Based on Raspberry Pi Pico – EEJournal

by Steven Leibson

August 22, 2022

[24-bit, 100Msps, 32K samples]

...

Instead, Dr. [Agustín Gimenez] Bernad harnessed the power of the two PIO (programmable I/O) engines designed into the device.

...

Even these PIO state machines are not capable of sampling at 100 Msamples/sec with trigger conditions, but gang all eight together with some imaginative hackery, and you have a logic analyzer.

...

[edge trigger at 100Msps, complex pattern trigger at reduced speed, fast pattern trigger for five channels at 100Msps]

...

Dr. Bernad has already implemented an SPI protocol analyzer for the logic analyzer and plans to implement additional protocol analyzers for I2C and RS-232, and system bus analyzers for old computers with sixteen address bits and eight 8 data bits.

...

[level translator PCBA]

...

Dr. Bernad developed his own GUI for the logic analyzer, explaining that it’s easier for him to develop his own Windows-based GUI than it is to use a 3rd-party GUI framework.

...
