Print
 

This download is for MV4th16 version 0.94b, sixth release. This is a cleanup build of the changes added in the version 0.94 build. I have included an update to the spinneret W5100 sample project found in the "Prebuilt" folder. The monochrome two pin TV  driver can now be used to display up to 80 columns and 28 rows using an 80Mhz system clock.

Example of using TCP with W5100

Print

This article contains examples on using the WIZnet W5100 Ethernet controller to provide TCP communications for MV4th16. The examples include; support for a TCP console for MV4th16, a simple TCP terminal, a TCP terminal server, and a simple WEB server example. The examples are configured for the Parallax Spinneret board.  The Spinneret board contains a Parallax Propeller chip, WIZnet W5100 Ethernet device, Epson RTC with large backup capacitor for date/time retention, and a Micro SD card slot. The examples make heavy used of the LOAD and THRU forth words to allow each of the examples to be loaded from the Forth block device, executed then unloaded from the limited system RAM memory. These examples apply to MV4th16 version 0.94b and higher. The example project can be found in the "Forth\PerBuilt" folder in the latest version of the MV4th16 project.

Using The Forth Block Device To Load and Execute Code

Print

This article is intended as a primer on using the Forth block device words to load and execute Forth source code under your programs control. This article may contain example code that can be used on other Forth systems however the examples are specific to MV4th16 Forth. The article first explains the main Forth words used to load Forth source code from the block device. Next we include examples showing how a Forth system can dynamically load and unload Forth words.
