  1. Hi, I recently bought a MSP-EXP430FR2355 launch pad to build a Weather station with NRF24L01+ so i have used a specific library Enrf24.h for ENERGIA. The code for below already works with my MSP-EXP430FR2433 but not with my new MSP-EXP430FR2355. I can't use the MSP430FR2433 beacause it doesn't have enough memory for me to add my temperature sensor BME280 with all code required by the sensor... On the other side i can receive the information ON and OFF with a Raspberry Pi send by the FR2433 but not with my FR2355. #include <SPI.h> #include <Enrf24.h> #include <nRF
  2. Hi guys, does someone know of a way to implement "lost signal" on the reciever side with Spirilis's ENRF24 library? I tried using rfSignalDetected() it seems to always evaluate to true. Because the while(!radio.available()) always just sits waiting until the data is ready I can't seem to think of a way to check if I stopped recieving data. Something like: void loop () { unsigned long lastRecvTime = 0; while(!radio.available()) ; if(radio.read(&data, sizeof(MyData))){ lastRecvTime = milis(); } unsigned long now = millis(); if( now - lastRecvTime >
  3. I want to use nRF24l01 RF wireless modules with MSP 430f247 processor. There is a project done on MSP430G2553 with the same wireless module; https://github.com/spirilis/msprf24/wiki#library-usage I want to use USCIB_0 part for communication interface. I replaced output pins in the program. When I debug the program step by step I have seen no signal at SPI line. Do you have any suggestion?
  4. Here is my current project and entry for the Hackaday Prize: http://hackaday.io/project/2375-Garden_automation_and_sensor_network The main purpose originally was to have temperature monitoring of a small outdoor greenhouse, but then I decided to expand it from there. For more info look into the project page via the link above. Description originally from my hackaday projects page: This is a project to create a small network of sensors in the garden, and possibly some automation. The sensor data will be logged on an embedded Linux server (probably a Raspberry Pi or BeagleBone)
  5. I am trying to do exactly what spirilis describes in the hypothetical remote sensing application on his wiki for the nrf24L01+ library: "A typical application of the nRF24L01+ which takes full advantage of the MSP430's touted low-power modes is remote sensing with periodic wakeup involving an MSP430 circuit attached to sensors in a remote location. An MSP430 using either the VLO or LFXT1 driving ACLK to wake up the device periodically will switch on the nRF24, take sensor measurements and once the nRF24 is ready (5ms Standby-I wakeup time has elapsed), transmit those to a base station, fol
  6. I couldn't find an example of someone using the Raspberry Pi as a receiving hub for sensor nodes that use the spirilis nRF24L01+ library and a MSP430G2553. I thought I would give it a shot since I think this would be beneficial to the community. I found a C library for the Raspberry Pi and nRF24L01+: https://github.com/stanleyseow/RF24. Class reference is here: http://maniacbug.github.io/RF24/classRF24.html There is also a newer python library but I haven
