Bidouilles liées au hackrf one+portapack

Début des festivités sur un PC Linux. Pour que cette page s'étoffe, faut finir la formation !

Ajout matériel

Ajout d'un haut-parleur sur le HackRF One assorti d'un PortaPack H1.

Page du github du firmware Mayhem

Extrait :

Attention, il y a pour moi une erreur dans cet extrait puisque si je connecte SPK+ et SPK-, je n'ai aucun son. J'ai connecté SPK+ et GND.

A speaker has two wires, SPK+ and SPK-. While there is no sound, the speaker floats on a magnetic field in the middle of its range. When SPK+ is high the speaker moves forward. When SPK- is high the speaker moves backwards. The distance forward and backwards depends entirely on the voltage level.

On the PortaPack, the speaker connector has 3 pins.

SPK+ is the pin nearest to the edge of the board GND is the connector in the middle, skip it SPK- is towards the centre of the board

H1 specific setup

On the H1, when you add the new speaker you may find that there is no audio. By default the speaker is disabled.

To enable the speaker:

    Settings
    UI Settings
    Ensure Hide H1 Speaker option is disabled (a red X)
    Click Save

Now a speaker icon will be present on the top line of the display. If the icon has an X it is muted. You can click on it to unmute, it will turn green.
