STM32-RFM69

Hi,

for the first issue:
_Static_assert (LastPort <= 0x0F, "PortName must be less than 16");

I’m using Arduino IDE 1.6.9 on Windows, with STM32 Core installed through the Board Manager. What else should I do in order to have the right gcc version?

It’s strange that nobody has tried those libraries on F401RE yet …
In July I was able to compile it without errors for an STM32L053R8 board (I was using a different version of the STM32 Core package) but there was no signal getting out of the RFM69HW module (checked with SDRSharp software and USB dongle). I suppose the problem could be related to libmaple compatibility you were talking about…

In the second library, the pins are not hardcoded: https://github.com/goran-mahovlic/RFM69-STM32

Thanks for your time!

Maybe some have tested and fix issue themselves in the code library…

For this one, https://github.com/goran-mahovlic/RFM69-STM32
I’ve just tested and it still some SPI_def which has not been renamed.
I’ve only added #define SPI_def SPI

Thanks! It now compiles after adding “#define SPI_def SPI” and deleting the other version of gcc.
I’ll let you know in case it works with the RFM69 module (hope to get some spare time during the weekend).

The SPI seems to work as I can read RFM69’s registry and temperature. Unfortunately, it doesn’t transmit anything at all…
As IRQ pin I tried both PA3 and PA10.

I think there is a bug in line 150: it should be _interruptPin instead of _interruptNum.

They are both used:

uint8_t _interruptPin;
uint8_t _interruptNum;

attachInterrupt() needs as first parameter the interrupt pin, not the interrupt number (whatever it supposed to mean).

Line 49: https://github.com/goran-mahovlic/RFM69 … M69STM32.h

I think one is used for defining the STM32 PIN and the other for the equivalent PIN on Arduino.

I saw that.
My previous comment still applies. Sorry if you don’t want to try it. Good luck.

Btw, I used to use this lib: https://github.com/LowPowerLab/RFM69

Btw 2, it seems that you are double posting: viewtopic.php?f=15&t=1582&hilit=rfm69&start=10#p31497

Hi Steve,

you got me wrong! I appreciate all the suggestions you give.
It’s just I’ve already tried to assign the same value, something like:
#define RF69_IRQ_PIN 3
#define RF69_IRQ_NUM 3

Again:
attachInterrupt() needs as first parameter the interrupt pin

Please specify the pin in PXY format (ex. PA3, PB8, etc.)

Do you think this would work (instead of changing the .cpp file):

#define RF69_IRQ_PIN 0
#define RF69_IRQ_NUM PA3 ?

Replace in line 150
attachInterrupt(_interruptNum, RFM69STM32::isr0, RISING);

Testing right now!

PS: compiled but it’s not working. In addition, I cannot read anymore the temperature with:

if (input == 't')
{
byte temperature = radio.readTemperature(-1); // -1 = user cal factor, adjust for correct ambient
byte fTemp = 1.8 * temperature + 32; // 9/5=1.8
Serial.print( "Radio Temp is ");
Serial.print(temperature);
Serial.print("C, ");
Serial.print(fTemp); //converting to F loses some resolution, obvious when C is on edge between 2 values (ie 26C=78F, 27C=80F)
Serial.println('F');
}

I’ve tried again with:

#define IRQPIN PA3

RFM69STM32 radio(CSPIN, IRQPIN, true, 3);

The library you pointed to, I’m using it with Moteino and RFM69HW and it works flawlessly.

I think you should use the same library which is working.
Please also post a simple test sketch to reproduce the problem.

Btw, which core do you use? The Arduino_STM32 or the STM32DUINO core?

Hi Steve,

I’m using the original library with Moteino (an Arduino clone).

The sketch I’m using with STM32F401RE is this: https://github.com/brainelectronics/RFM … -STM32.ino

I only tried to connect the IRQ to PA3 or PA10 for testing (obviously, changing the settings accordingly)

Which original library?

At the moment I’m trying to make this library work with STM32F401RE board: https://github.com/brainelectronics/RFM69-STM32

The original Lowpower Lab’s library I’m only using with an Arduino compatible board and it works only on Arduino as it is (https://github.com/LowPowerLab/RFM69)
