I am trying to connect the following devices to a Nano
nrf24l01+
st7735s
BMP280
It looks like the nrf24l01+and st7735s both use the same pins. Is it possible to redirect the pins to a different pin such as the following
st7735s
pin 13 could be pin D6
pin 11 could be pin D5
if I am incorrect does anyone have a suggestion on how I should layout the pins connections?
From what I have read these devices use the following pins. if I am in correct with my pins usage please correct me.
nrf24l01+
ce - 3
cs - 4
mosi - 11
miso - 12
sck - 13
vcc - 3v
gnd - gnd
st7735s
a0 - 8
resist - 9
cs - 10
sda - 11
sck - 13
led+ - 3v
led- - gnd
BMP280
scl - A4
sda - A5
vcc - 3v
gnd - gnd
The end goal is to have two different devices. The sender will collect the temp every 30 seconds. After 5 minutes it will average the samples and transmit the data to the receiver and the receiver will display the temp for each receiver on the screen.
