The question of how to do GET requests with the ENC28J60 arose recently so here is an example. The code assumes some familiarity with the ethershield examples. #include <etherShield.h> static uint8_t mymac[6] = {0×54,0×55,0×58,0×10,0×00,0×28}; This is the first of several posts about the IM-Me pink wireless toy from Mattell. The aim of this post is to collect all of the relevant links I have found useful from the web. You can currently get one (or more) of these toys for £8.99 at Amazon Both of the major Arduino ethernet shields (standard Arduino and NueElectronics) have issues with the MISO signal which prevent them being used with other SPI devices. The standard Arduino shield uses the Wiznet5100 chip – this chip has a flaw in that the CS signal does not tri-state the MISO line. The Wiznet application note can [...] A while back @andrewoke was bemoaning the availability of an open source HD4470 I2C LCD and keypad controller. So I wrote one – the code fits into an Attiny2313 (just). ATTiny2313 chips are available for under $2. ********* aProtocol is essentially a hub polling devices, it does allow for devices to announce events but in the main it is polling. The Arduino XBee shield uses a resistor divider to connect the TTL 5V Arduino Tx to the XBee Din line. This has the side effect of pulling the Din line to GND if the Arduino is not asserting the Tx line. Problem is that the Arduino does not have control of the TX line during [...] Updated 26/2/2010 I have been extending my range of inputs to the CurrentCost, Ardunio, Xport pachube logger. A lot of devices use XML these days – and parsing the XML by hand is quite complex. I use a CurrentCost CC128 power monitor and also Twitter. Both of these have an XML interface. Over the last couple of months I have been developing a simple XML parser as an Arduino library – it is [...] The Arduino Nokia 3310 shield come from NuElectronics. I have been using this shield with an Arduino Ethernet shield together with Andrew Lindsay’s Nokia 3310 library. I upgraded the library to be compatible with multiple SPI components, you need to bend digital pin 10 so that it does not make contact and then connect it [...] |
