RF remote via SPI - SYWindveer - 2020-10-19
I connected an Arduino with a 433 receiver to the RasPi via SPI using GPIO 7,9,10,11,27 and a level shifter.
There are some initial values in the configuration menu, but I see no remote codes coming in
The Arduino and receiver work fine with the RC Switch library.
Is there a way to monitor the communication?
RE: RF remote via SPI - seandepagnier - 2020-10-19
did you program the arduino with hat.ino?
the rc switch library has some bugs.. I don't use level shifters I run the arduino at 3v3 and this requires 8 mhz crystal.
If you run just pypilot/hat/arduino.py you can monitor just events from the arduino
RE: RF remote via SPI - SYWindveer - 2020-10-20
Yes, I am using the latest hat.ino from the repository and the latest tinypilot image.
I am using a 5V nano and my receiver is 5V as well, because that's what I have around.
I am getting the error below, I have no nmea time source connected, could that be the problem ?

please use python3 not python2

Same error on tinypilot, is tp using Python 2 as well?
RE: RF remote via SPI - seandepagnier - 2020-10-24
try "python3" for python3
RE: RF remote via SPI - SYWindveer - 2020-10-24
python3 arduino.py does show output from the RF remote which is great.
In the pilot config screen I do not see any RF codes coming in.
Should tinypilot use Python 3 ?
I can see both versions are installed, but I don't know how to change the default.
tc@box:/usr/bin$ python -V
Python 2.7.13
tc@box:/usr/bin$ python3 -V
Python 3.6.0
tc@box:/usr/bin$
Just realized my nano runs at 16 MHz, I'll get me a 3v3 8MHz mini, and try again.
RE: RF remote via SPI - seandepagnier - 2020-10-25
it can work at 16mhz if you change fcpu in the makefile but the arduino needs 5 volts for 16mhz. It may work at 16mhz at 3v3 but it's not rated for it.

I have an 8MHz Pro Mini now.
I am seeing these codes in Arduino.py

In the configuration menu I can't program any rf buttons
Pressing keys on the remote, then select a command key in the setup menu, nothing.
Am I doing it wrong?
I have no controller or gyro connected , does that matter ?

You should be able to press a key on the remote, see it display the code in a browser, then click the button in the browser to assign it.
If you press the key on the remote again, it should display the command and apply it as well.
