ARDUINO to MAX7219 LED Matrix display (Easy guide setup, WIRING
1 3 Posts 35 Views Log in to reply 4 3 19 Thank you @eiten for you suggestion. I will try it. I wanted to be independent from HA, just as a fail safe in case of problems. I am not relying on the time keeping of the arduino, but on a real time clock module.

The nRF24L01+ module is designed to operate in the 2.4 GHz worldwide ISM frequency band and uses GFSK modulation for data transmission. The data transfer rate is configurable and can be set to 250kbps, 1Mbps, or 2Mbps.

The module communicates with the Arduino using the SPI pins. SPI pins are different in Arduino UNO and Arduino MEGA. ARDUINO UNO SPI PINS: - MOSI: 11 - MISO: 12 - SCK: 13 - SS: 10 On the ARDUINO MEGA: - MOSI:51 - MISO: 50 - SCK: 52 - SS: 53 So, please make sure that you wire the module to the correct SPI pins. I hope this helps.

Connect power pins from NRF24L01 to the Arduino as shown below: NRF24L01 ARDUINO VCC 3.3V GND GND CE and CSN pins can be connected to any digital pins. Then in RF24 library, you can specify which pins you used. I chose pins 7 and 8 because I will use them in the examples. On Arduino UNO boards SPI pins are connected with some digital pins.

The MAX7219 communicates via the SPI interface, so it only needs 3 data pins to connect to a microcontroller. In addition, we can daisy-chain multiple modules together for a larger display using the same 3 wires. Setting Maximum Current and Brightness

When I straight connect the NRF24L01 to SPI1 it doesn't work. After some research it appears as if it's not written for boards that have more than one SPI bus. I found a workaround by changing the code in pins_arduino.h to the following - essentially commenting out the original #defines for PIN_SPI_MISO, etc. and changing to the SPI1 pins.

The module has the generic nRF24L01 IC from Nordic semi-conductors which is responsible for transmission and reception of data. The IC communicates using the SPI protocol and hence can be easily interfaced with any microcontrollers. It gets a lot easier with Arduino since the libraries are readily available.

Max7219 can be powered from 5V of Arduino. I did a project where 4 Max7219 were powered. With 9V into the barrel jack the 5V regulator would overheat after a while. With 7.5V things ran smoother.

Gromo is a principal village in the commune of Bergamo with several walking paths that lead to the renowned Parco delle Orobie Bergamasche, a protected natural park of 70,000ha (700sqkm) at the foot of the Alps that border Switzerland. The village architecture is characterised by grey stone with black slate roofs, and at its centre is Piazza Dante, which has original frescoes from the 13th.
