Simplescope v1.1 released

Eugene — Wed, 14 Mar 2007 09:08:09 +0000

This is a maintenance release of the product that includes the following fixes:
1. SISAN v 1.1
  1.1. Added SISAM88 hardware schematic
  1.2. Fixed TX/RX typo on SISAM690 schematic
  1.3. Fixed issue with beam pattern affecting ruler pattern
2. SISAM1 v 1.1
  2.1. Fixed diagnostic failure, which made product unusable if high baudrate cannot be set
  2.2. Fixed issue with BREAK is not handled properly

SISAN Overview

Eugene — Tue, 11 Jul 2006 23:32:25 +0000

SISAN – SImlpe Signal Analyser – is a Win32 application capable to control Simple Sampler hardware, acquire sampling data, store sampling data to a file, and visualize logical signals reading data either from a file or directly from the sampler. SISAN provides basic facilities for timeline navigation, beam and surface look customization.

SISAN can be used as a standalone application for visualizing traces generated by other means.
When accompanied with SISAM, it offers a complete solution for sampling and visualizing logical signals: Simplescope

Visualizer limits:

Min scale factor:	0.1 us / pixel
Max scale factor:	500 us / pixel
Max time extent:	214 s

Overclocking COM port

Eugene — Tue, 11 Jul 2006 00:59:22 +0000

Most of recent mainstream motherboards have USART chip supporting speeds above 115200. However, there are few obstacles.

First of all standard MS driver for COM port does not support baud rates above 115200. This can be easily overcome with installing a third-party driver. Currently I am using Serial XP by Leo Yuriev. Another diver I have tried is HiSerial.

Secondly, analog part of the COM port hardware may not be capable to work on high speeds. This can be easily detected with a simple hardware loop test. Even if the test did not show good results it may only mean that COM line driver is not powerful enough and it may worth testing only COM port receiver

Thirdly, RS232 level converter must be capable to work on high speed. This post provides some test results on various level converters.

Fourthly, PIC must produce good bit timing, so data are not corrupted. This post gives some technique to overcome this issue.
