Hello to all!
I'm using some Arduinos to send sensor data (Temperature read from DHT11) trought NRF24L01+ antennas. Untile here all works very well.
My setup is like attached image...
Sorry, but cannot draw very well with Fritzing. Consider the upper right device as the NRF24L01+ transceiver.
Then, I was able to wire and work on another Arduino having a ST7920 LCD 128x64 connected in Serial Mode. What I would like to do is to use the LCD on one of the existing Arduinos with the NRF24L01+ antennas but cannot figure out how to wire/setup it.... I'm not sure it's possible... 'cause:
a) the ST7920 in Serial Mode cannot be used; the NRF24L01+ still use the SPI communication also cannot share it
b) the ST7920 in Parallel Mode needs more digital PINS and I haven't enough
c) I've thought to use a TLC5940 to multiply my digital pins but seems it uses SPI as well, also, like point a, I cannot choose this mode.
Is there a way to add on an Arduino NANO all those devices in any way? (also ST7920 + NRF24L01+ + DHT11).
Thank's for the help!
Simon
