e# language vision as an 'embryonic development' story

In this post I present my vision of e# reflected through history of assemblers. For each stage in the assemblers’ history I am providing presumptive equivalents in e#, incrementing the complexity of each next example.

Benefits of using e#

I envision the following benefits of using e# It will allow writing better quality code in shorter time It will reduce maintenance cost by providing abilities for regression testing (on a simulator or in-circuit debugger) It will reduce impact of migrating to another device/platform

e# roadmap

Refine vision Establish requirements Design a device metamodel

Concept of a new PL for embedded applications

Preface I would like to discuss with you my ideas on new programming language for embedded applications, denoted further as e#. I value your time and therefore in this post I am trying to be short and precise as much as possible.

Simple sampler as a "COM2" plugin

This post presents an alternate implementation of SISAM hardware – a “COM2” plug-in. It is designed for plugging in ahead of a bracket DB9 cable, usually used for accommodating a second serial port. This implementation uses a different MCU – PIC16F88, which allows the application to utilize 30% more RAM for the sampling buffer.

Speed tickets on RS232 Level Converters

As practice has shown, simple level converter with -12V supply derived from DTR/RTS is not capable to work on high speed. Therefore I have made several tests on speed with the original PNP-based design and a RS232 line driver SN75150 and publish test results in this post. Test summary is given in Table 1.

A Simple Environment for Automated Testing

This post describes how SISAM can be used to build a simple environment for automated testing of embedded applications.

SISAM Protocol

SISAM uses RTS/CTS flow control for reading command and DTR flow control for sending acquired data. This means that PC should set RTS before sending commands and watch for CTS (e.g. use CTS sensitivity option). When PIC goes into data acquisition mode, it sends an ASCII string starting with Y4-MODE: followed with new mode description. […]


Simplescope is a simple solution for data acquiring, signal visualizing and analysis. It is build up from three components: SISAM – PIC-based dual channel sampler SISAM1 a COM interface to SISAM SISAN – Windows application that controls sampler, acquires and visualizes logical signals Please follow respective link to read more about components and their capabilities. To […]
