Constructed wire harness for the bicycle!
Got both switches and Hall Effect device soldered onto headers, which connect to the harness.
The harness uses a 6-pin Molex connector to connect to the turn signal and a 12-pin molex to connect to the main console.
Updating the website with pictures, code will probably be uploaded tomorrow at the latest.
As far as the prototype for B.I.T.S., it just needs to be mounted in some fashion onto the bicycle for demos on Thursday!
Fine tuned the GetIO() function
After much tweaking, I got the GetIO() function to be within 0.001 miles/min in terms of distance.
As far as speed goes, I have NO IDEA if it's even close to accurate, but it seems to top out at ~30 MPH, ~44 KPH
12:01 AM my board died!!!
1:30 AM: Tried powering up my board again and it works! Turns out there was a crossed wires on the Hall Effect Device.
Created a proof of concept design for the Hall Effect Device and one switch
Works perfectly! Moving forward now to construct a soldered model.
Finalized UI design for my system. See the pictures page.
Also added SD card check at the startup of B.I.T.S. and can read information from "settings.txt"
Successfully figured out how to write to SD card, both strings and variables
After much trial and error, especially with variables, I finally can write data to the SD card
Working with FatFS to modify SD card contents
Very simple, easy to use file system module. I highly recommend it, check it out at this website
Soldered components onto the PCB board
All components, aside from the Molex connectors, have been soldered onto the board
Received 3 copies of the turn signal PCB from EzPCB
The board was manufactured in 2 days and shipped via DHL. Made it from Hong Kong to Bellingham, WA in a week!
Had I ordered the board a week before Chinese New Year, it would have been received much sooner
Ordered the turn signal PCB from EzPCB through their Educational Sponsership program
Under this program, they provide the PCB for me so long as I promote their services.
More information about this program can be found here
Successfully loaded a program onto the microcontroller using Keil and a JTAG device
Received the LMZ14203 Breakout Board from Sparkfun which will all me to make BITS portable
by converting the 9.6V from the rechargeable battery to 3.3V to power the microcontroller and turn signal
Successfully loaded a test program onto my microcontroller using Eclipse
Through loading the test program, found correct driver for my LCD on the microcontroller
Working on getting Keil's Microcontroller Development Kit for ARM to flash software onto my microcontroller
Purchased parts from SparkFun.com to construct turn signal
Began work on website template
- Prototype for demos on Thursday basically complete!
