NRF24L01 issue

Projects General Guidance
1

so im building a finger sensor scanner. ive set the code up so that after three attempts there is an error code that comes up on the LCD screen and then it will send the message to a remote location with another arduino to get it. im using the NRF24L01 as my transmitter and receiver. my issues is that in my void setup the line of code "radio.begin()" causes all text on my LCD screen to scroll continuously until there is nothing left. does any one know how to solve that issue?

thank you and stay clean out there

ive also attached my code so you can see what it looks like, transmitter portion commented out in the setup as well as the function called void transmitter()

The rf24 uses the SPI pins. On a Mega, the SPI pins are MISO-pin 50, MOSI-pin 51, SCK-pin 52. See the problem?

Choose different pins for the LCD.

More members will see your code if you post your code as described in the how to use this forum sticky.

even if im using the ICSP pins?

The pins on the ISCP header connect to the processor's SPI pins (pins 50, 51, 52 and, optionally, 53) . You cannot use the SPI pins for the RF24 and the LCD. Choose different pins for the LCD.
