Graphic LCDs / SPI connection to NHD-C12832A1Z-FSR-FBW-3V3
« on: January 25, 2016, 04:45:34 PM »
Hello,

This is my firt time working with LCD Displays and I'm not sure that this works. Can you check my circuit?

Capacitors are X5R series from Samsung Electronics. 0402 size, 6.3V.

I connected so:

SI --> MOSI
SCL --> SCK
A0 --> MISO
CS1 -->  SSEL
RST --> mcu GPIO

It's right?


Best regards,

Thanks Paul,

Then I'll used 3V3 for supply and backlight.

Best regards

Hello,

I am using this model for my project  with 3V3 voltage with one TPS61201, http://www.newhavendisplay.com/specs/NHD-C12832A1Z-FSR-FBW-3V3.pdf

It suffices with one resistor or is it better to use a 3.0V LDO?
