Its Week 10!!

Week of 1 - 5 October

• Struggling with finishing up with codes!!!
• Compiling problem
• Looked for a software that can compile my C code.

Option : CCS, Reads51 from Regal Corp, C51 from Keil.com

(Problem : How to compile my big codes? Maybe it is not even the size. ??)

Week of 8 - 12 October (expected to do..)

• Finish Compiling codes
• Code testing
• Implement hardware
• Written thesis

Coding!!!

24-28 Sept

• Integrated ADC
• Written thesis on ADC
• More research on card interface
• SD Card Interface

( Problem: The SD Card Interface is 10Kb, but CC5x Compiler allows only up to 4Kb. )

1 - 5 Oct (Expected to..)

• Finish up with coding
• Board testing
• Start thinking about hardware implementation
• Written thesis!!!!

Analogue to Digital Converter

10 Sept - 14 Sept

• Experiment ADC with assembler MPLAB via LED simulation
• Improvement on assembly language skills
• Move to CC5X C language compiler - implement to support with MPLAB program

17 Sept - 21 Sept

• CC5X compiler - solved implementing CC5X to MPLAB assembly (Monday)
• Multimedia Card (MMC) Card Interface
• Combine MMC and ADC Interface

(Problem:

1. Support MPLAB to implement CC5X
2. CC5X compiles C code to ASM code. However, CC5X has the limitation of not compiling code more than 4KB

)

24 Sept - 28 Sept (Expected to do)

• Combine MMC and ADC Interface
• SD Card Interface
• Combine SD Card and ADC Interface

Assembly Language

Problem : No basic on assembly language
Solution :

Self Tutorials from the internet. (Still finding myself lost)

28 August 2007 - Tutorial on assembly with Gaetano (Understood basic assembly)

Week of 29 Aug - 4 Sept
Practical tutorial on assembly language on flashing LED with PIC16F877A hardware implementation.

Pin Address

Hardware on PIC16F877

Week of 3 Sept - 7 Sept

Implement assembly coding for project on PIC16F877

Presentation on Progress

Presentation on progress was held on the 10 & 17 of August 2007 with the rest of other projects related to Electrophysiology.

Progress overview are as below:

SD Card Coding

Having a little trouble with eclipse. Still getting used to familiarise myself with the programming language. The boxes in the image basically shows the main classes (for each box) and Im allocating roughly 3 days to do coding for each classes.

File Allocation Table

File Allocation Table

Four different sections

• The Reserved sectors, located at the very beginning. The first reserved sector is the Boot Sector. It includes an area called the BIOS Parameter Block (with some basic file system information, in particular its type, and pointers to the location of the other sections) and usually contains the operating system's boot loader code.
• The FAT Region. Maps of the Data Region, indicating which clusters are used by files and directories.
• The Root Directory Region. This is a Directory Table that stores information about the files and directories located in the root directory.
• The Data Region. This is where the actual file and directory data is stored and takes up most of the partition.
