[SOLVED] N64 Analog Joystick Issue with Teensy LC
-
Im not sure what your wanting to do here do you want to scale +- 1024 to +-32678 ?
-
When I try to configure the analog stick in Retropie, some of the axis doesn't get picked up. However, when I test the joysticks in the terminal, jstest /dev/input/js1, they are showing up. How can change the range of the analog sticks so they can be configured or how can I increase their sensitivity?
-
Just finished work what is the minimum and maximum picked up with jstest for each axis?
-
LEFT JOYSTICK (approximate values):
-
X = 2400, -2400
-
Y = 2400, -2400
RIGH JOYSTICK (approximate values):
-
X = 2200, -2500
-
Y = 2400, -2400

I only gave a few Arduinos here they need some extra work to get hid working when i get time ill have a look whats going on. Are them values a standard return ie.
Joystick.X(Xstick); -
What do you mean a standard return? The values are what it says when I run jstest /dev/input/js1 and move the sticks around. I'm using the new code that I posted yesterday. So its just Joystick.X(Xstick). It seems like the range for joysticks aren't in line with the range Retorpie has. How can I increase the sensitivity of the analog read without messing up the corrections we made to the old code? Before I just did Joystick.X(((analogRead(18)-ANALOG_CENTER) * 1.6) + ANALOG_CENTER);. However, ANALOG_CENTER equals a fixed value and we know the center values are in a range so when I tried to add it in, the joysticks went back to their messed up their state a couple of days ago.

try this code
/* Buttons to USB Joystick Example You must select Joystick from the "Tools > USB Type" menu This example code is in the public domain. */ #include <Bounce.h> #define ANALOG_CENTER 512 int Xstick; int Ystick; int Zstick; int Zstickrotate; int upperBound=530; int lowerBound=495; // Create Bounce objects for each button.

looked into this a little more seems the zaxis is 8 bits. Im not sure of your exact setup or what lib you are using you would need to check with your lib.

Well, I tried your code and everything seems to be working good so I'm going to say this fixed the issue. Thank you so much!

no problems at all glad it worked out :)

Simple comment. I had the same issue but my lowerBound had to be fix to value 490. It's important to check the value when your stick go back in place. My left stick showed a value of 491 when It came back from left to center. Now, Everything's working fine
I suggest to use joy.cpl to find It.
