GET or POST to web server using WiFly Shield in BASIC

Here is some sample code that will use a WiFly (Roving Networks aka MicroChip) shield to do an HTTP GET or POST to a webserver.

This is a good way to use WiFi and gather data on an ARM

Visual BASIC serial communication with ARM

We often get asked about communicating between a PC and the ARM in BASIC. The USB connection emulates a serial port and can be used to transfer data/control between the PC and the ARM processor. Attached here is a simple example in Visual BASIC that sets up a communication link between a PC and the ...

Re: BASIC compiler update

This version adds CONST BYTE ARRAYs to the BASIC compiler

The syntax is--

CONST CHARS AS BYTE = {1,2,3,4,5,6}

Other bug fixes--

Some array CONST use was not running correctly in the PC emulator, most but not all have been fixed.

I2C monitor

I had an LCD panel that I'm trying to interface to, but like normal had no documentation on the backlight initialization sequence. The backlight was controlled by an I2C device (PCA9532). But I did have a working version with another processor. So hook a couple lines up to a SuperPRO, and less than ...

Big Current Source

>from the Yahoo Forum >looking for a 1A controlled current source A current source can be built with a DAC and a resistor divider in your case to get a 0 to 0.1 V reference, an op amp for feedback with a big MOSFET with a low resistance and small current sense resistor (remember it's dissipating a l...
