I think this library also worked well with STM32F4 discovery board, but as soon as I declare
RF24 radio(PA3,PA4)Cheers, Ollie
post a link to the board, although i suspect which one it is. i’ve 2 with a socket.
check the wiki
also this line intrigues me

2. If the LED is ON when PD13 is “LOW”, then your problem is actually the “Myboard.print()” function. And this, as I mentioned before, it may has to do with one of the latest commits in the repository (from xymopen), which introduces some problems. In this case I would recommend you to use this version, the version of the repository before the problematic commit. Just download and extract the ZIP, as usual.
This is exactly my board,I’ll try your suggestion, glad that you answered me,
Thanks
EDIT: what do you mean by “use millis() to provide something as data to write to the radio.”? Can you write down the specific command to implement what you said?
the logic behind removing the dht aspects and using millis is building blocks is that millis is a known and easily testable function, Serial.println(millis());
removing the dht aspect temporarily is to remove a potential problem. solve that by using their example as a test of dht.
using millis you can just create a packet structure with counter and millis as long int fields.
the dht example code i think converts the values to an ascii string for printing, but you could send the raw values as a field.
there’s getting started sending data example from rf24, essentially using notionally ‘good’ code.
combine the two sketches as a third and adapt.
a long time ago, my maths teacher was happy i was 3, 4 or 5 chapters worth ahead in the exercises, but not that everyone else got the same solutions.
mind you, he objected when i worked each side of ‘prove this equals that trig equation’ exercises. one forward, other backward until they met, 1==1 or 1 == 0 oops. i still don’t follow why.

Now things are totally a mess, I hope anyone could help me write a code to transmit/receive data using nrf24l01 with stm32f4 discovery . Because there are so many conflicts in using the libraries provided by previous authors in this forum
i’ll go looking for it

Hey Manny, can you show me specifically how can I get it work?
Here’s what I did:
+ Commented out network.update(), because this line makes my code stuck!
+ I used the SPI library from here : https://github.com/rogerclarkmelbourne/Arduino_STM32 (in STM32F4/libraries/SPI) – I cut and paste it in the path: C:\Users\ASUS\Documents\Arduino\libraries\
+ I used the DHT library from here: https://github.com/markruys/arduino-DHT
+ And the RF24Network library from here: https://github.com/maniacbug/RF24Network

Sorry don’t have a F4 to try out.

it shouldn’t be looking there at all, is there a quirk with f4 spi?

it at first flagged missing library maintainer, add fred also added [email protected] for the email
thought i’d add it in, did, tried re-compile, same of course (i knew that honest

Just simply comment out the line extern HardwareSPI … in your HardwareSPI.h file. If I recall correctly, this file is under …\STM32F4\cores\maple\libmaple
Comment out all the SPI code in your sketch you just need to #include <SPI.h> and SPI.begin() in set up.
Another thing I noticed is you’re using SPIClass(3) which on the STM32F1 that I’m using shares the pins with JTAG debug, to get round this you will need to put disableDebugPorts() in setup. Not sure if this effects the F4 but it wouldn’t hurt to try it.
disableDebugPorts();
The number of SPI pins is actually able to change in my program, so as you said, I changed it to SPIClass MySPI(1). That’s means I dont have to use your disable port command
I copied your lib under the folder hardware\Arduino_STM32..\STM32F4\libraries
I also changed the #include “RF24.h” inside RF24Network.h to #include “RF24_STM32.h” so that it fits your lib.

Btw, have you seen this lib? https://github.com/jaretburkett/RF24-STM

Thank you all.
the question is closed
It’s not my topic and not my first post,
I don’t know how to add a message.
Tell me what you need and how to do it.
You can’t do that.
I thought as you indicated it worked and you said “Thank you all. ” you must have started the tread
On the OP (and I ) can change the thread title and its best if the OP does that
