PICSimLab is a realtime emulator of development boards with MPLABX/avr-gdb debugger integration. PICSimLab supports microcontrollers from picsim, simavr, uCsim, qemu-stm32, qemu-esp32, and gpsim. PICSimLab has integration with MPLABX/Arduino IDE for programming the microcontroller's boards. As the purpose of PICSimLab is to emulate real hardware it does not have any source code editing support. For code editing and debugging the same tools used for a real board should be used with PICSimLab, such as MPLABX, Arduino IDE, or VSCode with PlatformIO. PICSimLab supports several devices (spare parts) that can be connected to the boards for simulation. Such as example LEDs and push buttons for simple outputs and inputs and some more complex ones like the ethernet shield w5500 for internet connection or the color graphic display ili9340 with touchscreen. The complete list of parts can be accessed in the documentation. Documentation at https://lcgamboa.github.io/picsimlab_docs/stable/

Check yafu on github for the latest code. YAFU (with assistance from other free software) uses the most powerful modern algorithms (and implementations of them) to factor input integers in a completely automated way. The automation within YAFU is state-of-the-art, combining factorization algorithms in an intelligent and adaptive methodology that minimizes the time to find the factors of arbitrary input integers. Most algorithm implementations are multi-threaded, allowing YAFU to fully utilize multi- or many-core processors (including SNFS, GNFS, SIQS, and ECM). YAFU is primarily a command-line driven tool. You provide the number to factor and, via screen output and log files, YAFU will provide you the factors. There is also an interactive environment similar to MATLAB or PARI/GP, where you can type commands and store results. YAFU is very customizable, through the optional use of many many command line parameters and a very capable expression inter

What is it? It's a Bootloader for Microchip, Atmel, NXP, TI and 8051 devices. A Bootloader is a firmware running in the microcontroler device which allows the user to send it's own firmware without the need of a programmer. This Bootloader consists of: - firmwares for many devices (this firmware need to be send to the device's flash memory with a programmer, only once) - a PC software which communicates with the bootloader firmware in the device and send the user's program in its memory Where does it come from? This Bootloader is based on "Tiny PIC Bootloader" made by Claudiu Chiculita. A special THANK to him!!! What can it do? It can program: - Microchip PIC10/12/16/18/24/32/dsPIC30/33 - Atmel ATtiny, ATmega - TI MPS430 - NXP ARM Cortex-M0+ - Silicon Labs C8051 And this: - with light modifications to the Bootloader firmware for new devices - without modifying your source code or using a special linker script - via GUI or command line prog - with automatic Reset

FastFlow is a C/C++ programming framework supporting the development of pattern-based parallel programs on multi/many-core, GPUs and distributed platforms. FastFlow run-time is built upon non-blocking threads and lock-free queues. Thanks to its very efficient CAS-free communication/synchronization support (e.g. few clock cycles core-to-core latency), FastFlow effectively supports the exploitation of fine grain parallelism, e.g. parallel codes managing very high frequency streams on commodity multi-core. FastFlow works on x86, x86_64, PPC, ARM, and Linux, Mac and Win XP/7. From Jan 1, 2018 code development migrated on GitHub at https://github.com/fastflow/fastflow

PPMScope is a do-it-yourself oscilloscope with an open source design. The intent is that the project can be constructed by an electronics hobbiest using the instructions included. The design is a compromise between features and cost. The bandwidth is lower than a commercial scope, so it's use is limited to signals of 500 kHz and below. It's sample buffer is also smaller than a commercial scope, however sufficient for most oscilloscope functions. This is a version based on the PIC16F877A microcontroller running with a 20MHz clock. The maximum sampling rate is 1 MHz with a 5 Mhz equivalent sampling mode. Currently, the computer interface supports USB, serial, and parallel ports. Good luck on the construction and I hope you enjoy your oscilloscope. I am happy to answer any questions or provide technical support for this design.
