Topic: Using SPI on the UNO Ethernet, feasible or not? (Read 504 times) previous topic - next topic

I am getting afraid that using the SPI LCD display on my UNO Ethernet will not work because of the usage of pins.

Does anybody now if it is possible to use the UNO Ethernet, or an UNO and an Ethernet shield, together with the SPI LCD display?

Thanks for your advice and insights!

It should be. The Ethernet interface and the SD card interface are both SPI, and those two devices play well together. Make sure that you choose a different chip/slave select pin for the LCD, and disable other devices/enable the LCD before reading from/writing to the LCD.

Trying to save some sensor values to the SD card, make them accessible over the Internet via an html page and have some of them displayed on the LCD, at the same time, so sounds promising to do that? Challenge is to find the right ports as a newbie...

In case anyone has experience, please let me know. Thanks!
