thanks for your reply, but i really dont understand this! ive had a look at the example code, and it features a rs232 component, which i do not have licence for and also there is no accelerometer data being read as far as i can see, im just after something to read the sensor then display it on a lcd...

hi guys, ive been playing with a MPU6050 accelerometer, gyro, and themo sensor, and it gives me the values, which is easy enough, but i have heard you can display a more accuracte figure if you do some calculations and use values from both accelerometer and gyroscope (complimentary filtering) does a...

sorry, i did realise that, and thanks for your example, however im using a 16x4 display and the word "Hello" is 5 spaces in, is there any way around this? its on the 4th line now though!

thanks,
matt

hi guys, i have had no problems running a 16x2 lcd display, and i assumed that driving a 16x4 would be pretty much the same, and i also assumed that when i type in the cursor numbers i could simply put x0, y4 and it would write to the 4th line on the display, however this doesnt seem to be the case....

i went to outputs - glcd ebm001 and connected it that way, it does respond slowly, however.

thanks,
matt

thats very interesting, because you can actually see the pixels changing along the screen, but to refresh the screen i have to clear the whole screen then it has to re build any boxes and text etc that i had put in place. it shouldnt be too much of a problem with what im using it for, but still a bi...

i have tested this on hardware, and unfortunately it doesnt seem to work, only a half of the screen seems to start up (horizontally) and also if you write text, it goes off the screen. when it starts up, half of the screen is white and the other side, all of the pixels are different random colours, ...

no problem, i will do that now, i hope that the driver can be fixed to it works properly, however as i said, the built in one seems to work well, just refreshes really slow?

matt

yeah, i did see that, but it doesnt seem to work as well as the built in driver in flowcode, only half the screen starts up and the rest is a mix of weird colours, bit of a weird one, i think!

thanks,
matt

hello,
thanks for the quick reply!
ive attached the program, in the simulation its super fast, but in real life that takes around 5 seconds to finish the program,
thanks,
matt

hi guys, i recently purchased this: http://www.ebay.co.uk/itm/141087179782?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT which i know isnt the correct display for use with flocode, but for the price i thought i would have a go, it works, but the refresh rate seems really slow, you can s...

thanks for your replies :) and thanks dazz for the advice, i have read that geckos dont generally chew wires, which is lucky, but they are shielded anyway, apart from the mains cable for the heater! however in the pet shop, they had wires everywhere, which looked messy to be honest, but they seemed ...

Hi guys, ive spend a bit of time working on a thermostatic controller for a new pet i only got yesterday, (a leopard Gecko) They temperature on the "hot" side must be kept between 30 and 32 degrees, and so it is set at 31c the cold side should be around 26ish, and the humidity around 50% i thought t...

hello, and thanks for the reply, after some further research, i have found this: http://www.ebay.co.uk/itm/141087179782?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT is this the same thing? because im trying to keep cost as low as possible! i cant wait to have a play, seems like it will...

hi guys, i dont use the E-Blocks, i normally just prototype my circuits on breadboard, and go from there, but i would like to know where i can get a GLCD from and how much for? ive been looking around, but they seem a bit pricy and i dont want to go and buy the wrong thing... plus the ones ive been ...

oh brilliant!

thanks, that worked great
simple when you know how, aye?

thanks again,
matt

hi guys, ive been writing a program to show the readings from a SHT21 sensor, but im hitting problems, again :( for some reason, im getting compiler errors, ive attached the fcfx file for you to see, it works in the simulation, but wont compile :( heres the errors: Flowcode1.c(1135:28): error: argum...

hello benj,
i see, this may cause me a problem, as when i try and place the accelerometer on the component window, it says i dont have a valid licence for this component! do i have to buy pro for this? im only a hobbyist, and cant afford to pay that unfortunately

matt

hi guys, im loving this forum, and the help people are so willing to give! and i do try my best before having to come here for help, but i am stuck....again :( iv egot a gyroscope sensor now, and i wrote a short program to show the x,y,and z axis... but all the numbers were weirdly jumping around al...

brilliant is there a easy way to create a if statement that would "detect" if it goes below say 0.1c? as in it can read the .1 increment? sorry, ill leave you alone now haha

matt

hello, just what i was looking for! just got to try and get around it in my head whats going on in that code! whats the easiest way to convert that to celcius? i have tried adapting the code to show me celcius, but it takes me back to square one with it not giving me a 0.1 decimal place :( thanks! m...

hello, and thanks for your reply!
unfortunately, I'm a proper newbie to all of this! and just looking through that flow code, just blew my mind! plus its in v5 and I'm running v6

is there a easier way to do this?
thanks again
matt

hi guys, ive been building a fish tank controller to detect the temperature by using a LM35, its connected to a ADC input, and then the value is read and displayed on the screen, for the moment, however its only showing whole numbers. how do i get it to show a temperature and also determine wether i...

personally i haven't really used any seven segment displays, purely because of the ridiculous number of wires, and they're not cheap! personally i use the 16x2 LCD displays, as they're only £2.50 each, and can easily display any character.... plus it makes your project look more techy ;) lol I'm afr...

to be fair, looks like a very simple project, a lot of my projects have massively long main threads, but if its doing what you want it to do, then no worries
