Hello

 

a couple of weeks ago i bouth this little display:

 

 

 

 

pin1: GND    = Ground

pin2: V         = 5V?

pin3: D0       = CLK

pin4: D1       = MISO

pin5: RST     = Reset

pin6: DC       = Data / Command

pin7: CS       = Chip Select (CSN)

 

only one problem, i cant get it to work

i have tried it for a couple of days now, and im at the point of throwing it out of the window

 

i have tried a couple of projects as base, but can't even find a good diagram for wireing.

 

 

does anyone have experience with this LCD??

Where did you find the pinout? Also I was not able to find any data-sheet with the command protocol. If you have it, could you post the doc/link?

 

Furthermore, do you own a regular Netduino (or Plus) or the faster Netduino Plus 2? For a similar display the new Plus 2 would perform much better.

I contacted the seller,

 

he sent me this link today:

i'm using the standard Netduino (framework 4.2)

At first glance you could try using the I2C way, because the SPI protocol requires a 9-bit transfer which is not supported.

The I2C should be feasible, although not so fast to play animations or similar.

Bear in mind to add a couple of pull-up resistors (e.g. 5k Ohms) to +3.3V.

 

Oh...I wouldn't throw it away: although an LCD won't give much satisfaction with a Netduino, you could have fun by adding an Arduino. At that point, the Arduino makes the "dirty job" and the Netduino the elegant one!

Thanks, 

 

i will look at the i2C way 

You mention pull-up resistors, on which pins?

 

Last Monday i order a Arduino, it seemed fun to combine the 2 boards into 1 project

Yes: of sure is funny...not trivial, but that's funnier!

The pull-ups are for the two I2C lines: SDA and SCL. You must add them externally.
