LCD

 

Hi folks,

copied this code from http://www.jeremyblum.com/2011/07/31/tutorial-13-for-arduino-liquid-crystal-displays/ but when i try to compile i get a error at void set up {}( function definition dose not declare parameters) i highlighted the part that gets this error ... but i can figure out whats wrong ...

Hello community!

I have started experimenting with a LCD and the Picaxe Serial Firmware chip (FRM010). The idea is to use it to display the values of an ADC input to help write code for my line follower.

I haven´t been able to display anything at all on the LCD (not even the welcome message). In the process of troubleshooting, my first stop is to confirm a weird pinout on the base of the winstar PCB.

I have found a place that sold these and I got 12 of them.

I have spent the time interfacing them to the Adruino board and mapping out what it takes to drive them.

For some reason these are hard wired for 8 data only.(sorry no 4 pin input)

However they work well. To display text on all 16 locations is tricky as you have to tell it to jump to another DDRam location.

I will see about getting an image of the device very soon.

hi have one of these 20x4 screens does any one have a pic of it attached to a picaxe 28x1 project board

hi i am going to buy a 16x2 lcd screen from ebay and need to know how to connect it to the picaxe 28x1 board

the lcd screen is the same as this one

any help is appreceated

Hi,

Does anyone know how to connect a LCD03 to a picaxe 28x project board?

EDIT: I've already connected the LCD successfully to the board :D.

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

hi

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

 

thanks for the input

Hey There,

I've hit a snag on a project of mine. I've been trying to build a servo calibrator (to test a servo's limits and test them on robots before they're connected to the motherboard) which should operate by positioning a servo depending on the position of a potentiometer, and display the pulse rate on a 16x2 LCD. I've built one before, with an LED display and a single servo output, but this one should handle two servos.

Except it doesn't. I won't even handle one.  There's two major problems I've found which I'm looking for solutions to.

Hi,

I am new to LMR but for those looking for a cheap lcd I have found a brilliant one on ebay for under five pounds! It is 16x2, uses the hd44780 parallel driver, so can be used with picaxe etc, and even has a backlight!

I have just bought one but have yet to try it with a picaxe, will let you know when (or if) i get it working. Just follow the link below:

Well recently I have been reading about LCD's and trying to figure out how I would use them with a picaxe 28x1. I am pretty sure you use a serout command followed by a number that corresponds with where you want the dot on the lcd. Bottom line though is that I have no idea how I would wire A LCD to the picaxe28x1 or how I would exactly program it. And what exactly is the baud rate? If possible could somebody please help explain this confusion to me? 

I have a Sharp LM5H40TA LCD screen that I took out of a Rocket eBook. I can take a couple of photos if you need.

I found this link for the datasheet.

I need a couple of standard servos to use on the roboduino if anyone is interested in trading. 

I have looked over CtCs post regarding similar issues with his LCD, but still can get mine to budge. I was hoping to get some guidance on my issue. The issue being I can't get the LCD to work or interface with my PICAXE. Like Ctc, I am using the serial backpack from SparkFun. Here is my code:
