Maplins (late supplier of electronic bits) stocked a range of LinkSprite products. One of many problems was they had a lot of rather ancient stuff that sat on shelves and was more of interest to archaeologists. With the loss of Maplins, it can be difficult to identify the particular items, but LinkSprite does still have a products wiki here.
Do be aware that the pins used by this LCD shield do not match those on the Arduino examples sketches. To make it more confusing, the example code on the LinkSprite site works (by setting the values in the initialization call) but has not had the pin selection changed in the comments.
If you use the Arduino LCD Shield "HelloWorld" example code, you need to change the pins used :
- LCD RS pin to digital pin 8
- LCD Enable pin to digital pin 9
- LCD D4 pin to digital pin 4
- LCD D5 pin to digital pin 5
- LCD D6 pin to digital pin 6
- LCD D7 pin to digital pin 7
- Wiper to LCD VO pin (pin 3)
//const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
const int rs = 8, en = 9, d4 = 4, d5 = 5, d6 = 6, d7 = 7;
Ensure that the pins are not in use by any other shields or added hardware.
