Pocket Programmer
The Pocket Programmer is designed for versatility and portability, allowing it to interface seamlessly with a variety of PICmicro® microcontrollers. The device operates using a single 18V DC power supply or alternatively, it can be powered by two 9V batteries, enhancing its mobility for field applications.
The core functionality of the Pocket Programmer is centered around its ability to program and patch firmware onto microcontrollers from the PICmicro® family, which includes popular series such as 12C6xx, 16Cxxx, 16Fxxx, and 18Cxxx. The programmer utilizes a serial communication interface, which simplifies the connection process with the host computer or other devices.
An important feature of this programmer is its onboard memory, which consists of 64KB of EEPROM. This memory capacity allows for the storage of up to 32 HEX files, making it an efficient tool for developers who need to frequently switch between different firmware versions or configurations. The EEPROM also enables the user to retain data even when the device is powered off, ensuring that essential programming files are readily available when needed.
The schematic design of the Pocket Programmer includes essential components such as voltage regulators, capacitors for noise filtering, and connectors for both power supply and serial communication. The inclusion of a microcontroller or a dedicated programming IC allows for the execution of programming algorithms and data management functions. The layout must ensure that signal integrity is maintained, particularly in the high-speed data lines associated with programming operations.
Overall, the Pocket Programmer stands out as a highly functional tool for embedded systems developers, providing a compact and efficient solution for programming a wide range of PICmicro® microcontrollers. Its combination of portability, power options, and memory capacity makes it suitable for both laboratory and field use.The Pocket Programmer is a stand alone serial programmer that can program most of the PICmicro®MCU range of microprocessors. (12C6xx, 16Cxxx, 16Fxxx, 18Cxxx) It works from a single 18VDC supply or with 2 X 9 volt batteries. Combine this with 64K of on board EEPROM which can store upto 32 HEX files and you have a truely portable programmer / patcher.
