some modifications for python 2.7.16 #9
Description
-
I used script: https://github.com/BLavery/lib_nrf24/blob/master/example-nrf24-recv-rpi.py ... thank you Brian Lavery 👍
-
radio2.begin(0, 25) csn=0 means pin nrf24-csn to rpi-gpio8 (CE0_N) and pin nrf24-ce to rpi-gpio25
-
while True: .... akpl_buf = [(c& 255), ... (like in another example)
-
I change library https://github.com/BLavery/lib_nrf24/blob/master/lib_nrf24.py :
-
after lines self.spidev.open(0, csn_pin) self.ce_pin = ce_pin i add line:
-
self.spidev.max_speed_hz=(4000000); because: RasPI: HARDWARE FAIL: Radio not responding, verify pin connections, wiring, etc. nRF24/RF24#205 (comment)
-
and to line 226 i use line "if isinstance(value, (int, long)):" (not: "if isinstance(value, int)")
-
