I need to be able to send raw data out of the serial port using Bonescript
command b.serialWrite. I set up an HTML Bonescript to send data and then
looked on the logic analyzer to see what bit pattern is sent out. The
pattern is always the ASCII value of the character whether the variable is
a text or number.
Does anyone know how to pass to b.serialWrite a value so that the UART
outputs that value?
so I want to have
var port = '/dev/ttyO2'; // set UART port
var data = 0x55 ;
b.serialWrite(port, data );
and for the bit pattern coming out of the UART to be 01010101
I tried using String.fromCharCode(data); but this only works for values up
to 127 (0x7F) since that is all ASCII goes to. This must not support
extended ASCII?
here is my html/javascript to test this functionality
<html>
<body>
Uart Byte:<br>
<input type="number" name="value" id='value'/>
<button onclick="uartWr()">SEND</button>
</body>
<head>
<script src="/bonescript.js"></script>
<script>
function uartWr() {
var b = require('bonescript');
var port = '/dev/ttyO2'; // set UART port
var data = document.getElementById('value').value;
// set baud rate and buffer size
var options = {
baudrate: 9600
};
b.serialWrite(port, data );
}
</script>
</head>
</html>
