JTAGulator alternative for RP2040 microcontroller based development boards including RPi Pico.
Connect the RP2040 microcontroller based development board running blueTag to your computer using USB cable. Connect the development board's GPIO pins (GPIO0-GPIO15 so 16 channels in all) to your target's testpoints on the PCB. Connect the development board's "GND" pin to target's "GND". Connect to your RP2040 using a terminal emulator. blueTag supports auto-baudrate detection so you should not have to perform any additional settings. Press any key in the terminal emulator program to start using blueTag. The firmware methodically pokes at all of the connected lines to figure out what kind of interface it is (JTAG, I2C, SPI, etc) and which line is hooked to which pin of that interface for you.
The ISA PicoMEM Extension board (For 8086/8088 PC) is a way to run Emulated ISA boards on a real PC. It currently connects the full 8Bit Memory and I/O Bus plus an IRQ to a Raspberry Pi Pico, through a multiplexor/Level shifter chip. The Pi Pico also has a 8Mbyte PSRAM connected in SPI and a MicroSD Slot. This GitHub Repository does not contains the Firmware at the moment, but PMMOUSE, PMEMM and PM2000 Source are available.
sf-hab.org's RP2040 based PicoBalloon Tracker PCB generation 1 for STEM education, designed by AG6NS.
The SIDKick pico ("SKpico") is a drop-in replacement for the SID 6581/8580 sound chips in the Commodore 64 and 128 computers. It has been designed as an inexpensive alternative to other replacements while not making compromises regarding quality. It consists of a simple interface board and a Raspberry Pi Pico (or compatible clone). The emulation is based on an extended version of reSID 0.16, and includes a few additional features.
Emulates the 6581 or the 8580 in single or dual SID mode. Has a built-in configuration menu that is accessed with a BASIC command (SYS 54301 for the c64, SYS 54333 for the c128). Supports stereo output if you hook a DAC up.
Uses surface mount components so this is not a project for the inexperienced or the faint of heart.
Welcome to 101 Things, a collection of projects that celebrate creativity and hands-on ingenuity. If you share a passion for making things, you've come to the right place. Each project uses simple designs, and basic tools, to push the creative boundaries of a home tinkerer. Join me on this exploration of crafting, coding, and constructing, as we unlock the magic of making, one project at a time.
This project turns the Raspberry Pi Pico into a USB I/O Board.
It implements the USB protocol used by the dln2 Linux drivers and in addition it supports 2 CDC UARTS.
