what is the INT pin (on NRF905 board/chip) in RaspberryPi4 example project ?

Please ask your question

Hi libdriver,

You write:

Board Name: Raspberry Pi 4B.

SPI Pin: SCLK/MOSI/MISO/CS GPIO11/GPIO10/GPIO9/GPIO8. GPIO Pin: CE/TX_EN/PWR_UP GPIO22/GPIO27/GPIO5. INT Pin: INT GPIO17.

Which pin on the NRF905 is INT ? I can't find that INT pin.

I use the PTR8000 board where pinout looks like this :

• VCC TXEN HW850 -
• CE PWR -
• UCK CD -
• AM DR antenna X -
• MISO MOSI NRF905 -
• SCK CSN -
• GND GND -

thx in advance

So is INT maybe DR of CD ?

[8OND007]

When I connect DR as INT to GPIO 17, the nrf905 -t sent works and ends normally. Don't you have to connect CD also somewhere ? How does the NRF905 and the pi known otherswise there is data received ?

[libdriver]

Thank you for using LibDriver. INT pin is connected to the NRF905 DR pin. When an interrupt is triggered, the driver will both analysis the DR and AM status and run the receive callback function with the triggered type param.

so PTR8000 board DR pin is connected to Pi GPIO17 do I also need to connect PT8000 baord AM pin to a GPIO on the Pi ?

[libdriver]

When DR was triggered, AM and CD must have been triggered, you only need to connect DR pin to GPIO17. When DR was triggered, the driver will analysis both AM and CD status at the same time.
