Several connections spi

Using Arduino Networking, Protocols, and Devices
#1

Hey !

First, sorry for my bad English, I'm French :wink:

I'm a beginner in arduino and I would like to connect a Arduino TFT and a RFID module in the same time.
These module use a SPI connection to run. But I don't arrive to use simultaneously the modules :confused:. I did some research on Google but without succes. Here is link of modules :

Arduino TFT here

RFID Module here
(The RFID Module is based on a RC522).

My answer : how to run spi several modules simultaneously ?

I believe I should use the Slave Select but what is the Slave Select port on the Arduino TFT ?

Thank you in advance ! :smiley:

My question: Where is your code?

tu as essayé le tft sans le rfid ?

ton tft est a base de quel controler ?

il faut essayer les exemples de la librairie tft, le cs de ton afficheur s’appelle lcd cs et est relié à la pin d10 arduino, il faut relier d9 a d/c afficheur, d8 a reset, plus le spi clk mosi miso

et encore il y a plein d’autres trucs à savoir : quel arduino utilises-tu ? les data du lcd sont-elles compatibles 5 volts (apparement oui), le lien de ton afficheur " this product is currently retired and the documentation will not be kept up-to-date" tu es certain que c’est celui là ?

tu as lu ceci iciiiiiiiiiii ?

arduino c’est bien mais ce n’est pas magique
