The ICP2GANG-DS Production Quality ICSP Secure GANG Programmer is a 4-channel in-circuit programmer (expandable up to 64 channels) that operates with a PC or as a standalone unit and simultaneously programs Microchip® 8-bit PIC MCUs and serial EEPROMs. The secure programming feature dramatically reduces the risk of unauthorized reconstruction of hex files, and also limits how many times the hex file can be programmed. It features ultra fast programming, 250mA Vdd drive current (per channel), programmable Vdd (2.0 to 5.5V) and Vpp (2.0 to 13.5V), programmable delay between Vdd and Vpp (0.1 to 250 ms), programmable clock/data speed (500KHz to 2.5 MHz), on-board 1MByte flash memory (per channel) and Windows® DLL functions and command-line interface for high volume automatic programming.

The SEC4CH-DS Secure Programming Upgrade can be applied to any Softlog ICP2GANG programmer. It dramatically reduces the risk of unauthorized reconstruction of hex files, and also limits how many times the hex file can be programmed. The secure programming upgrade must be installed by a user with administrative (ADMIN) privileges, and internet access is required. Once installed, the programmer can be delivered to a contract manufacturer or other un-privileged user. Programming is then controlled by environment files created by the ADMIN with strong encryption.

From http://www.segger.com/embos-for-pic32-cpus-and-microchip-compiler.html

embOS for PIC32 was developed for and with Microchips’s compiler version 7.62.09 and supports all memory models offered by this compiler. It comes with easy to use start projects for Microchips’s MPLAB workbench.

embOS

Real time operating system

embOS is a priority-controlled real time operating system, designed to be used as foundation for the development of embedded real-time applications. It is a zero interrupt latency*, high-performance RTOS that has been optimized for minimum memory consumption in both RAM and ROM, as well as high speed and versatility. Throughout the development process of embOS, the limited resources of microcontrollers have always been kept in mind. The internal structure of embOS has been optimized in a variety of applications with different customers, to fit the needs of different industries. embOS is fully source-compatible on different platforms (8/16/32 bits), making it easy to port applications to different CPUs. Its’ highly modular structure ensures that only those functions that are needed are linked, keeping the ROM size very small. Tasks can easily be created and safely communicate with each other using a complete palette of communication mechanisms such as semaphores, mailboxes, and events. Interrupt Service Routines (ISRs) can also take advantage of these communication mechanisms.

* High priority interrupts are never disabled by embOS.
