Here are links to the pages of stuff I will post here from time to time.
An 8051/8052 Instruction OpCode Chart
This is a chart of all 8051/8052 instruction opcodes organized in numerical order. It is a handy quick reference guide as well as it shows the original Intel concepts of how the various opcodes were assigned to bit fields in the opcode byte.
A Cool ASCII Chart
This is a handy little ASCII chart that you can copy and put on your desk top.
An 8051 Delay Loop Calculator
This is a spreadsheet utility that allows you to devise a delay subroutine to suit your needs. The sheet shows the structure of the generic delay subroutine which is then customized to your platform requirements. [Best if accessed with Internet Explorer and Excel].
Using Custom Symbols On LCDs
Here is some information on using "soft font" symbols in the CGRAM of a Hitachi type character mode LCD controller. Ask the question "Are 8 soft symbols ever going to be enough?".
Automatic Baud Rate Detection For 8052
Here is a programming example of how to perform automatic baud rate detection for the UART port on an 8052.
Using Cygnal's JTag Debug Facility
I show you how I utilized the low cost Cygnal IDE and Development platform to support code debug in retrofit on an existing platform.
Prototyping With A 0.5mm Flex Cable
A scheme showing how to attach a COG Graphics LCD display module, that comes with a fine pitch flex cable, to an 8051 evaluation board.
Prototyping With High Integration 8051 Parts
How to take advantage of high integration 8051 derivatives during the prototyping and software development phase of your project.
Using Bitmapped Fonts With a Graphics LCD Module
This page introduces a development I did to display graphics fonts on a COG Graphics LCD display module. There are pictures of the hardware, displays and a link to download the code.
Using Spark Gaps as ESD Protection for Microcontroller Inputs
Here I tell how you can successfully incorporate PC board spark gaps into a microcontroller board design to protect the electronics components from the high voltages of ESD spikes.
