Seminar Handouts

Day 1--introduction and overview of microcontrollers

Day 2--SH-1 specifics

Day 3--developing code

Light flashing code presented on day 3
Tachometer code presented on day 3
ITU-DMA-TPC-DAC system code presented on day 3
Complete code for implementing a heads-up digital tachometer using a VFD display.

Hands on Portion

PWM demo code. This code will drive the SH1WH-MD1 at a PWM base frequency of 20 KHz. It sets channels 0-3 to identical values, but you can easily pick out which channel does what from the code.

Seminar Hands-On Portion Code and Development Tools

DOS-based tools:

Suggestded install procedure

DOS-to-SH1 cross compiler and complete source examples. (7.5 MB zipped ) Complete gcc/binutils for DOS, see setenv.bat for environment variables that need to be added to autoexec.bat. sh1wh directory has a templdos directory with DOS templates, plus code examples for RTC, FLASH, FPGA, and monitor code (some code examples will require a makefile transplant to make them compile under DOS, as they were written in the linux environment).

Java-based terminal interaction program (153K zipped); provides binary upload protocol support. Requires JDK1.1.6 or better, plus java.comm extensions. JDK can be retrieved from the Sun Java website; will require about 30-40 megs to install.

java.comm (263K zipped) of the proper version (1.1 beta, I believe) for the JTerm software. Once you have unzipped the file, read the PlatformSpecific.html file and follow the install instructions!

Sample items that need to be added to your autoexec.bat to make the comm software and dev environment work.

Linux-based tools:

Obtain gcc and binutils sources from prep.ai.mit.edu, and configure for cross-compile to sh-coff; for more detailed directions and a gzip'd tarfile of my source tree, contact me.

Linux-based serial-port uploader source code by Matt DeBergalis. Use in conjunction with a standard linux serial communications package (like minicom); you can fire up both the uploader and the comm package simultaneously for convenience. Ignore any warnings about locks on the serial port.

FPGA Libraries

FPGA Libraries for Xilinx Foundation series of design tools.
