HCFiler - An efficient embedded SDHC FileSystem

Postby cfbsoftware » Sun Aug 27, 2017 12:11 am

HCFiler - the efficient embedded filesystem for SDHC cards announced recently in the Astrobe for RISC5 forum is now available for v6.2 Astrobe for Cortex-M3 targets. The total compiled code size of the 3 HCFiler modules is only 4 KBytes. It has been tested on the LPCXpresso LPC1769 and mbed LPC1768 boards and can be downloaded from the following links:

ReadMe.htm
Read this before doing anything else.

HCFiler.LPC1769.zip
A copy of the HCFiler modules for the LPC1768/69 which have been tested on the LPCXpresso LPC1769 and mbed LPC1768 boards. Also included is a new version of SPI.mod which is required. It differs slightly from the v6.2 Astrobe Library version.

HCFiler.Windows.zip
The installation file for HCFiler for Windows and the ReadMe file.

There are two example modules included in the LPC1769 zip file which illustrate how the HCFile modules can be used.

1. HCTest.mod
You will need an 8GB SDHC card that is newly formatted. HCTest creates an HCFiler filesystem on the card and generates 10 text files of increasing sizes and one binary file and writes them to the disk. It then displays a directory listing of the disk. You should then be able to use HCFiler for Windows to copy the files to a PC.

2. HCReadSpeed
HCReadSpeed checks to see if there is an HCFiler filesystem on the SDHC card. If there is reads 1024 sectors from the card and displays the time taken to read them. It should take a few seconds to run.

The source code for HCFiler for Windows (written in C# and Gardens Point Component Pascal) is also available on request by emailing support at cfbsoftware.com.
