Great, a very clear video. I'm very pleased with it. I did have a few small issues to resolve to get it to work. First the value of the LED resistor is too high it needs to be a few hundred Ohms, not 10K. Second the receiver and transmitter codes as downloaded on 2 March 2020 have the wrong pins defined for the LED and the switch. Once changed to #define led 1 and #define button 0 it all worked just as explained in the video. Thanks again great job!
This video worked for me! I spent a couple days trying to get this to work - a lot of conflicting information out there. The critical piece that this video mentions is to use tmrh20'S rf24 version 1.3.2 - As I write this we are up to 1.3.4, anything other than 1.3.2 doesn't work (other comments made mention to modify the rf24.cpp as well but didn't mention that they were modifying that version). Also it's important to use the proper attiny84 board manager. I know at least the attiny board manager from David E. Mellis (v1.0.2) works with what's described here. Anyway following these instructions EXACTLY I was finally able to get my attiny84 and nrf24l01 working. Note, I have a breakout board which includes a voltage regulator and bypass caps - a good alternative to using the am1117 regulator. thank you
I know we are up to version 1.3.4 that's why mentioned the library and boards versions because everyday there is new update and you can't catch up with everything, thank you
Can you explain me the code please, If i have no pushbutton in receiver section But after pressing transmitter button receiver automatically send msg and transmitter led blink.
The wiring diagram is correct. Because the ATTINY series does not have a SPI, it has USI Universal Serial Interface. The MOSI,MISO,SCK are for the ISP. Look at the data sheet USI DO,DI
If you run the whole system using 3.3V it'll never work, i designed my circuit the same way as you are saying ,using 3.3V it didn't work for me at all and i wasted so much of my time figuring out where the problem is so yea anyways, what you have to do is power the IC using 5V and use 3.3V only for the NRF24LO1 module.
i supose that it must be easy, just send and receive more "messages" and just decode them... like serial print/serial read with the console, u have a big if else if else...
I see the author has a good video on this - check his you tube site or put this in youtube search "How to Program Attiny84 Using Arduino Uno - By CSASystems"

mine is still not working, i tried everything

Can you explain a lil more since i cannot find rf24.cpp file
Great job man. Thanks for share.
Clear and simple, thanks
Very good job !
thank you so much !!
Good video. If you use the ATTINY84V you don't need to use the voltage converter
hi, i dont know wich 84 i have but if i connect with 3,3v RF doesnt works, i think it has his own coverter
Can you explain me the code please,
If i have no pushbutton in receiver section
But after pressing transmitter button receiver automatically send msg and transmitter led blink.
Please give circuit diagram of nrf24l01 to atmega8a🙏🙏🙏🙏🙏🙏
Long time use this circuit is best or not
Helo everyone. I have a doubt. The PIN 8 on Attiny isnt MOSI ? Why is connect in PIN 7 of NRF, if this PIN is MISO ? Is correct ?
The wiring diagram is correct. Because the ATTINY series does not have a SPI, it has USI Universal Serial Interface. The MOSI,MISO,SCK are for the ISP. Look at the data sheet USI DO,DI
HELLO CAN YOU HELP RUN NRF24 ON ATTINY13 THANKS
why not power the ATTiny84 with 3.3 Volt?
default power for ATTiny is 5v.
Yes ATtiny84 will run on 3V3. Yes make sense to run it on 3.3 volts.
According to the ATtiny84 data sheet, it will work up to 8Mhz at 3.3V. For higher speeds, up to 20Mhz, use 5V.
If you run the whole system using 3.3V it'll never work, i designed my circuit the same way as you are saying ,using 3.3V it didn't work for me at all and i wasted so much of my time figuring out where the problem is so yea anyways, what you have to do is power the IC using 5V and use 3.3V only for the NRF24LO1 module.
Didn't work for me as ATTiny 85 doesn't have a SPI port😢
the link is not found (not working). please resend again
Can you how to make nrf24l01 3 pushbutton and 3 led ? Please
i supose that it must be easy, just send and receive more "messages" and just decode them... like serial print/serial read with the console, u have a big if else if else...
Can you send me sketch coding please by gmail
Link doesn,t wotk
how to upload code to Attiny84
