Meanwell LDD driver: for those who want to dim to 0 using Arduino

If the 18b20 sensors are the same as before the you don't need to re-do the addresses as they ought to have been written into your specific Jarduino sketch. I had a similar issue when I blew a Mega and I discovered that in blowing the Mega I actually blew the 18b20 sensors as well. I swapped them out and set up the new addresses and worked perfectly. Another thing I did was I took out the 4.7k resistor and installed a variable pot resistor and found that due to the distance of the sensors from my Mega the optimum resistance was 3.9k and lastly I gave the sensors its own 5v supply.


Hey guys,...I got a new 18B20, have it hooked up ready to go,...brought up the arduino program, went to Examples, and unlike before I don't see Dallas Temperature on the list? I'm suppose to click on Dallas Temperature which brings up "Tests" that leads me to the addressing. What am I missing? Thanks,---Rick

What controller sketch are you using? Jarduino, Stilo?? it sounds like you are missing the relevant libraries within your sketch.

sorry another thing did you change your preferences at the beginning of the arduino 1st window? you have to do this and close and reopen to get arduino to look at a specific file.
 
15' is no problem, if you were talking hundreds of feet maybe. I'm running just under that distance from a StormX which is limited to 10mA on the PWM signals, no problems what so ever, standard arduino can output 40mA. So you should be just fine.

Thanks!



Anyone have like 3 x 4up LDD-L boards available?

Hey Proietti,(or any Jarduino guys),...I think I have the 18b20 thing worked out. Now the screen is not showing the Jarduino program. I reloaded the Jarduino program to the board, and the little leds flickered as it was loading, the screen is lit, but the program is not showing?? Is there a way to check to see if I need to order another screen? I have plugged and unplugged the screen shield into the Mega a bunch times, just to see if it would show the program for just a second, but no go. Don't know what happen now,:headwally:any suggestions will be appreciated.---Rick

ps. sorry for the question in the LDD thread

Are you using a mega shield vers1.1? and are you using a long 40 IDE cable to link your screen to the shield?
 
rick make sure you have all the Jarduino libraries do you get any errors during the compile?? also check to make sure you are using the right pins and also the correct driver

//TOUCH PANEL and ITDB02 MEGA SHIELD
//(Mega Shield utilizes pins 5V, 3V3, GND, 2-6, 20-41, & (50-53 for SD Card))
ITDB02 myGLCD(38,39,40,41); //May need to add "ITDB32S" depending on LCD controller
ITDB02_Touch myTouch(6,5,4,3,2);

are using this set up of the uft I have my Jarduino files at work or I would post mine from the script
 
Hi guys,...thing is, I had it up and working for a long time. That's why I'm confused as to what happen. It was working last week when I was trying to get the pwm fan to come on with the 18B20's. I couldn't get the fan to come on, so I got a new 18B20 in and was going to address it, when I didn't see the Dallas test set up on the sketch. So I was trying to fix that issue @ Proietti's advice(change preferences), now the Dallas test is back in the sketch, and I eeprom clear, then upload the Jarduino sketch, the little led on the board flickers like its uploading, but now nothing comes on the screen. The screen is lit up, but no Jarduino? I'm not using a patch cable on the screen, its plugged directly into the mega. This is where I'm stuck. The board looks like it uploads, so I don't know if the problem is the screen, or the board or??? I might need to see if you can take a look at it rott. Unless you guys can throw another idea at me. :confused:---Rick
 
Very baffling??????? Sounds like to me that your screen has gone (don't quote me on this). I have had a few screens give up on me already.
 
I'm thinking in that direction also. Mainly because the board looks to be uploading the program each time I reinitiate it. Thanks,---Rick
 
for got to ask have you tried to clear the eeprom and upload some of the test sketches that come with Arduino just for testing
 
[QUOTEfor got to ask have you tried to clear the eeprom and upload some of the test sketches that come with Arduino just for testing][/QUOTE]

Yeah.. there is even a sketch to test and calibrate your screen
 
Yep I clear the eeprom. I ordered another screen,....it will be hear by friday. I'll try a couple test sketches. Like I said it appears to upload the Jarduino sketch, and the screen is lit but no picture. I'm kind of baffled. Up side if I find out its something simple,...I'll end up with two screens:headwally:
 
most of the time it is a software problem before a hardware one but you said you pulled the screen off a lot maybe you did some thing to the soldered end where all the pins are I really don't know have you tested them to make sure they have continuity that would be fast and easy
 
check the RTC connections...maybe change the battery too?

Can you tell me if there is an Rtc issue,... the screen will not show the picture? I remember when I first built the project, I had a issue with the rtc and the only real problem was the time on the screen needed to be reset each time I turned it on. The onboard battery was only for RTC backup.So I'm not quite sure if the two would have something to do with the Jarduino program from showing up on the screen. Thanks,---Rick
 
you have the LCD directly pluged in to the TFT ? and then that pluged directly arduino ? and nothing on the screen? the jarduino code is exactly the same as it was before?
