Javelin uart

Istha Powron

Hi All,

I love the Javelin, it packs a lot of punch and is great for prototyping quickly.....However it is far too expensive to build into products.

I have a Uart problem......

I want to write; "Time = 332" as a serial output.

I know I can use uart.sendstring for "Time ="

I also know I can use uart.sendbyte to send individual characters, but how do I take the value of integer "Time" and send it as a string to an LCD? i.e.

What is the Javelin equivelant of SEROUT (, , "Time = ", DEC[noparse][[/noparse]Time})

ANy Help appreciated.

Istha

The easiest way is to use the Format package.

char buf[noparse][[/noparse]20]; //to hold string output
int time = 23;
Format.sprintf(buf,"time = %d",time);

generates "time = 23",0 in array buf

My adapted Uart class has a sendString method that takes a char array as parameter
so you can use afterwards
myUart.sendString(buf);

The·Format class is here:

Just put the Format.java file in folder
<Javelin Install Path>\lib\stamp\util\text

(create folders with the above exact names if neccessary)
Use
· ·import stamp.util.text.*;
to use the Format class in your java files.

Rename the original Uart.java to Uart.org
and copy the new Uart.java and UartTools.java to folder
<Javelin Install Path>\lib\stamp\core
