I am doing my own AVR kit. I connected LCD 8x2 on port A and B (RS - PA1; R/W - PB4; E - PA0; DB4-7 - PB0-3) . When LCD is not in the circuit nothing work like power supply is off. When LCD is in the circuit everything run. Connect and disconnect LCD is one of the important part of this kit.
A friend of mine is using a picaxe 20m2 to drive a milford instrument 20x4 LCD with a serial backpack. However, when he turns it on, it just comes on with a screen filled with triangles. The LCD is connected to pin 0 .The code he's running is below. What is the problem?
PS: This is my first post, so sorry if it's in the wrong place.
I am just going to make it clear that the boards are not currently going to come preprogrammed with some kind of serial LCD backpack code or other code. It will be up to you to program it how you please, but all the capabilities are there. I will be posting example code though and hopefully some tutorials to get started.
So I took the quiz on free day over at Sparkfun.com . After about an hour of answering a questions in between re-loading pages, I finally answered to questions correctly before it was all over. So I got $20 worth of parts. So I didn't know what to buy so I bought some random parts for fun. I ordered these products:
Today i just received two packets in the mail. In one of these was an lcd which i bought for less than 5$ incl. shipping, while in the other was a 434 mhz rf link kit, which cost around 8$. So far i haven't tested either, as i received them moments ago. I will soon be using them though, proabably to make a custom arduino rf controller, i only need a second arudino..
anyone knows what LCd best suits my project?.. the project goes like this: An LCD will dipslay a graph of temperature profile of a heater -- that is, a thermocouple connected to the heater sends signals to the microcontroller and the microcontroller must send signals to the LCD to graph the temperature versus time line graph.
If anyone knows, how should the program go?..please help me
i'm looking to add a serial LCD for my cat feeder but is it possible when using 18 Pin High Power Project Board .if yes..how is the connection...sorry if the sound stupid but i rather ask first rather than waste money with part that doest fit.
p/s:i would also add a clock Upgarade to the board.do i have enough connection
