Libraries

[Bobbla]

Hallo

I've written a small library, or at least that is what it is suppose to be. Its for the I2C temperature sensor TC74, its written in mikroC PRO for dsPic 6.0.0. I'm wondering because I want to make myself a "standard" of sorts for writing libraries.. and I was wondering if there was anything that should be changed.

Also, if you have any "standard" of your own please share the information.

Thank you.


EDIT: Really?? nothing wrong?? nothing to add?? I find that hard to believe.

what connector did you use?

in these indicators is designed connector soldered directly to the PCB, but you can unsolder and wires

Hello Catcatcat

Thanks for sharing your codes for SSD1306 OLED displays.


May i ask you some questions :

- Did you also get SPI mode working with PIC18 ?

- Does your code could work with ADAFRUIT SSD1306 OLED displays  : http://www.adafruit.com/product/326

- Where could we buy from Europe OLED displays (CNK109632 ) working with your libraries  ?
http://voron.ua website has no English language ( or, i did not find it yet   )


I tried to compile your project code : oled_8080_Grafica_web with MPLAB X and XC8 v1.12 but i get outstanding warning that i can't fix :
Can you help me please ?

Many thanks,

[Catcatcat]

But try these files, I used it in a project with the radio receiver used indicative serial I2C. Video work with display http://youtu.be/PMQ2pezKwzI

[lcn]

Thanks,

In your web site what code should I download if I want to use SSD1306 working with SPI interface ?

[Catcatcat]

I did not have such a need, therefore, with the driver I used only I2C. In the near future I will return to this indicator is not planned. SPI I have only used the driver SEPS114A.

[lcn]

Thanks, i will use I2C circuitry then.
I can't register on your website, so i can't download your lastest SSD1306 driver.


Does your library will work with any screen size : 0.96" or 1.3"
or, it needs to be modified to get it working with 1.3" screens ?

[Catcatcat]

Will work with any display size.
Try again to join and I will check that there is not obtained.

[lcn]

Thanks CATCAT, i received a password to log-in on your website.
However i did not find the XC8 project archive for SSD1306, can you tell me where i could download it ?

Could i use any PIC18 MCU with I2C interface ?
Is the crystal ( Fosc ) speed is very important for SSD1306 ?

Thanks CATCAT

I try to build a lab board in order to connect an OLED screen inspired from schematic.
I can't find any components supplier that sells inductor  L1 : 2.2 - 47 uH

What is the brand of the part "DE070x" ?
Can you tell me where your order that part ?

The datasheet suggests to use one of the following, but Farnell and Radiospare do not have those in stock either :

for TPS61040 :
10 mH Sumida CR32-100
10 mH Sumida CDRH3D16-100
10 mH Murata LQH4C100K04
4.7 mH Sumida CDRH3D16-4R7
4.7 mH Murata LQH3C4R7M24

[Catcatcat]

may use any inductor and any upconverter. One condition that would have been required on the output voltage.

Hello Catcatcat

I've received my SSD1306 OLED 0.96" screens.  

I try to adapt your I2C library to work in SPI 4 wires mode ( DC, CS, MOSI, SCK )

I'm able to display demo characters on the screen but i have a  question please :

In this line, why X argument,  that is used for setting X position is negative : -1 ?

Code:

String_OLED("catcatcat.d-lan.dp.ua",0,0,0,-1,1);

[Catcatcat]

hi, if the argument is negative, the function is activated alignment line on the middle of the screen. This is convenient when you need to display a character string exactly in the middle of the display (without calculation beginning on X).

[lcn]

I found that when using larger character size, argument -1 does not align the string properly on the screen

Code:

String_OLED("OLED Display",0,4,4,-1,2);

However it works properly when i use width and height = 0

It looks that '-1' argument does not work with symbol_OLED function, do you confirm '-1' only work with strings ?

--

I did not understand what is the purpose of ticker_OLED and tickerB_OLED, i do not know how they work
Can you explain me please ?

--

How could i scroll a string horizontaly, is there a function to do that ?

--

I do not find rectangle, line, point function in your I2C library, they only exist in 8080G,
I tried to adapt them for SPI 4 wires use, but i did not success, the following defines get troubles and compiler don't want them :

Code:

#define bitset (var, bitno) ((var) |= 1 << (bitno));           // set
#define bitclr (var, bitno) ((var) &= ~ (1 << (bitno)));       // reset

[Catcatcat]

I did not understand what is the purpose of ticker_OLED and tickerB_OLED, i do not know how they work
Can you explain me please ?

only for character strings

I did not understand what is the purpose of ticker_OLED and tickerB_OLED, i do not know how they work
Can you explain me please ?

it "tickers".
ticker_OLED - designed to output strings stored in the program memory type const
tickerB_OLED - to output a character array formed in memory

[lcn]

Thanks,

How could i scroll a string horizontaly, is there a function to do that ?
