I2C:
The way this looks in c
void changeResistance(){
BYTE sbuf[100];
DWORD n;
hCom = CreateFile( temp, GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);
//set-up com port settings
if (INVALID_HANDLE_VALUE == hCom)
{
printf(“Error: Could not open the RS232 port!”);
getch();
}
sbuf[0] = 0x55; //controller command
sbuf[1] = 0x58; //address
sbuf[2] = 0x00; //internal address
sbuf[3] = 0x01; //# of bytes to be sent
sbuf[4] = 0x0A; // steps of resistance
WriteFile(hCom, &sbuf, 5, &n, NULL);
ReadFile(hCom, &sbuf, 1, &n, NULL);
getch();
}
Your supposed to set-up the com port settings which is not shown here. The ReadFile is not really used in this program but would allow you to read the data you just put in to confirm it.
Repairing the hand:
Repairs are almost completely done. Everything is attached and most of the pairs are responding with good sensitivity. The only pair not working is the index finger. For some reason the top was settled 100ohms higher then it was supposed to be. Ground off this connection and glued a new strain gauge and terminal to it.
I2C:
Still not working but here are some notes.
Continuing working on paged data sources…
Also working on installing Helios and configuring Dynamic web applications. following phil’s notes.

ALTER TABLE `budget_amounts` DROP `MIPR_requested_date` ,

DROP `comments` ;Working on creating a paged data collection system where, essentially, the data collection only loads the parts of the data currently being viewed. It is basically a paged data sources where unused pages are thrown away to prevent a continual build up of data on the server.
Started by going out and looking at the latest and greatest examples of database to Flex UI using BlazeDS. The most promising and generic seems to be accessing a database through Hibernate and the JPA API. It maintains an in memory cache of the data and takes care of syncing it with the database (which can by any relational database, HSQLDB, mySql, Oracle, etc.).
I made a simple, non-paged data service that returns a list of fake customers (name, email, phone) and after one day can display a datagrid of 15,000 customers in flex in under 1 second. I’m going to up the number of entries in my database for 100,000 and see what happens on the flex side. I may also trying to add more columns with much more data per row to see how that affects timing and memory.
Once I have an idea of timings and the most efficient way to do things without paging, I’ll try paging the data and see how much of an improvement that is.
Useful Stuff:
ALTER TABLE `funding_requests` ADD `outlay_amount` DOUBLE NULL AFTER `reimbursable_amount` ALTER TABLE `direct_cites` ADD `outlay_amount` DOUBLE NULL AFTER `obligation_amount` ALTER TABLE `funding_requests` ADD `contract_id` INT NULL ,
ADD INDEX ( `contract_id` ) ALTER TABLE `funding_requests` ADD FOREIGN KEY ( `contract_id` ) REFERENCES `project_portfolio`.`contracts` (
`uid`) ON DELETE SET NULL ON UPDATE CASCADE ;
