1. µISP - At a Glance
Overview
Congratulations for purchasing a µISP In-System Programmer. Based on the
Algocraft proprietary WriteNow! Technology, the µISP Series of In-System
Programmers are professional programming instruments dedicated to the
programming of devices. µISP can either work connected to a host PC (RS 232,
USB, LAN connections are built in) or in standalone mode.
The programming cycle execution in standalone mode may occur by simply
pressing the START button or through some control lines.
Its compact size and versatility allows a simple integration into production
environments, manual and automatic.
The µISP series is compatible with the entire WriteNow! Series in order to allow an
easy migration between the models. This is very interesting in order to migrate to
multi-site solutions whenever needed into production.

Connectors Overview
µISP has several connectors for interfacing to a host PC, to an Automatic Test
Equipment (ATE), and to the target system(s) to be programmed. The following
pictures show where the various connectors are located.
▪The USB connector is used to communicate with a host PC system. µISP
can also be powered by this USB type C (5V) port.
▪The LAN connector is used to communicate with a host PC system.
▪The multifunctional STATUS LED shows the status of programmer and the
result of the project execution.
▪The START button executes the programming process with the last
downloaded project.
▪The ISP connector is used to interface to the target system(s) to be
programmed.
▪The CONTROL connector is used to interface the instrument to an ATE or
other systems. After the configuration of the parameters, the programmer
can be controlled by I/O lines (START, BUSY, PASS/FAIL).
For details and pinout of the various connectors, see the “Connectors” chapter.

2. Programming Installations
Algocraft’s µISP series finds different applications into the device programming
field: into an on-board programming system for standalone stations or into
automatic test equipment. It can be used for a single programming or for a multi-
device parallel programming using different units.
Stand-alone –Manual Programming
Once the programmer is configured, the programming cycle is executed by simply
pressing the START button. The result of the programming is verified by the status
of the multifunction LED (BUSY/PASS/FAIL). µISP can be used as a handheld
instrument in standalone mode for in-field programming.
Stand-alone –Automated Programming
After the configuration of the parameters, the programmer can only be controlled
by I/O lines (START, BUSY, PASS/FAIL). The needed signals to control the
instrument in standalone mode are located in the “CONTROL” connector.
Multiple Programming system
By using a simple USB HUB or LAN switch, it is possible to create a parallel
programming system.

3. System Setup
Software setup
Install the last software version of WriteNow! Setup available on our web site
www.algocraft.com under downloads > software menu.
To install the system software, you must log in as Administrator.
The WriteNow! system software setup installs all of the required components to
your hard drive. These components include:
•The WriteNow! Project Generator utility;
•Command-line utilities and Interface Library;
•Documentation in PDF format
Launch the Project Generator application, that is located under Programs >
Algocraft > WriteNow! Software > Project Generator.
Configure your µISP instrument. Choose Settings > Select Hardware Model, and
specify your µISP model and communication settings with the PC.
µISP can be connected through USB, LAN and serial port (RS232).
Hardware setup
To setup µISP, you must follow the steps below:
•Connect µISP to your PC through the provided Ethernet or USB cable.
•Power up µISP (by USB Type C (5V) or using the provided power supply).
•Set up LAN or USB port.
•Check µISP communication sending commands via WriteNow! Project
Generator utility.
Project setup
Projects are sequences of commands collected in a text file. The project file
contains all the target device information and user settings. Use the WriteNow!
Project Generator utility to create or edit a project file and then follow the Project
Creation Wizard steps.
Connect to Target Device
Connect µISP to your target system through the ISP connector. To view the
connections for your selected target device, select Project > Show ISP Connections.

µISP User's Manual

Interfacing with your Test/Programming
Equipment
µISP can be controlled in three ways:
•By manually sending commands and receiving answers, using the Project
Generator Terminal or any other terminal application;
•By configuring the instrument so that it can work in standalone, that is without
a connection to a PC;
•By building your own PC software that interfaces to the instrument (for more
information, see “WriteNow! API” on Programmer’s Manual).
Hardware Test
The diagnostic procedure is a very easy way to verify if any hardware faults occur.
Use the provided test-board to check the programmer hardware functionality.
Programming Drivers
µISP comes with preinstalled programming drivers (algorithms) that support
common microcontrollers and memories.

4. Standalone Mode (low-level
interface)
Overview
µISP can work with no connection to a PC (standalone mode). In standalone
mode, the instrument is controlled through a low-level connection interface
(CONTROL connector). With this simple interface it is possible to start a project
(START) and check the result (OK/ERR).
Signals
The needed signals to control the instrument in standalone mode are located in the
“CONTROL” connector and are explained as below.

5. Power Supply and Modules
Power Supply
µISP can be powered in two ways:
•Through a 5V power supply connected to a USB (5V) connector.
•Dedicated lines in the “CONTROL” connector.
Relays Lines
µISP features two lines (RLY0 and RLY1) on the “ISP” connector for driving an
external relay barrier or a demultiplexer module.
When you create a programming project using the Project Generator application,
relays are by default closed at the beginning of the project (with the #relay –o
close command) and opened at the end (with the #relay -o open command).
These signals are driven to ground when a #relay -o close command is
executed, and driven to a weak pull-up at 5.5V when a the #relay -o open
command is executed.
Demultiplexer Module
The demultiplexer module is designed to increase the number of ISP channels.
The Reed relay technology ensures true galvanic isolation.
If the BUP (board under programming) is powered through the µISP at
voltage greater then 5V, we suggest to use the AC/DC power adapter to
power the programmer in order to avoid to exceed the maximum USB current
limit (500mA)

One of the most important parameters to take into account for ISP wiring is
the connection length.
For this reason, the programmer should be placed as close as possible to the
BUP (Board Under Programming) keeping the ISP wiring length as short as
possible.
All the ground lines available on the ISP connector should be wired to the
BUP.
