SPI PROGRAMMER WITH TEENSY CODE

Hopefully someone can look at your code and see if there is an issue there. Anyway with a scope you can look at the clock and the enable and then you should see some bits go by when the enable is valid, if it is set up that way. Maybe that is exactly what they are doing. If all they want to do is shuttle out some switch positions via SPI they only need a couple of 74HC597 to do this not a PIC. Just because it uses a PIC16 doesn't prove anything. Just because it has 5 wires doesn't prove anything. Zener wrote:I just cannot find any reference that says it uses SPI.

If I have to, I'll breakdown the stick handle and check the circuitry inside that but I obviously want to avoid that until I've ruled out everything else. I guess I could check the frequency of the clock and that the SS signal is regularly switching between low and high (depending on the voltage, perhaps I could check that with a multimeter or LED) but I wouldn't know what the data input should look like. I don't know much about it but I imagine the fact that it's registering an input, albeit a strange one, even just on that one button must mean that the Clock and SS signals are going to the stick and that the stick is sending data out to MISO, so I'm not sure what viewing the signals on a scope would tell me. In addition, the chip on the original circuit those wires go to is a PIC16C64 which the datasheet confirms has SPI. I'm just relying on the work of those who've previously done this conversion but as there's only five wires coming out of the stick for numerous buttons/hats then it would make sense that it's using SPI. From the code it appears the Arduino is the master and should be clocking the switch positions out of the joystick. With a scope you would look at the SPI clock, enable, and data lines to see if they were acting as they should. I will assume you confirmed that somehow. I can find no evidence that the joystick even uses SPI. Zener wrote:I am not an expert on any of that. I don't really want to dismantle the handle to check the wiring inside that, as I can picture all the buttons/hats falling off and being a nightmare to put back together, so if there's an electronic way to diagnose the problem I'd rather do that. The guides all seem to say to select USB - Joystick in Arduino IDE but I don't have that, only 'Keyboard + Mouse + Joystick' or 'Serial + Keyboard + Mouse + Joystick', but I imagine either of those should work just as well and it is seen as a joystick in Windows.Дoes anyone know about Teensy and SPI specifically and can think what might cause this behaviour? Would it happen if one of the SPI wires wasn't connected properly or would nothing at all happen then? I imagine the +ve and GND must be right or it wouldn't even be doing anything and I've got no reason to doubt the other wires are correct as well.

The only pin that seems to need defining in the code is SS, which I've set to 10.

Unfortunately, that doesn't work and the only button that does anything is the red pinky button (BTN S3) at the base of the stick, which triggers on all buttons 1-18 and upper-right diagonal on the hat as well! This send_now() transmits everything all at once. the computer does not see any of the changes yet.

Because setup configured the Joystick manual send, take the SS pin high to de-select the chip: send a value of 0 to read the SPI bytes take the SS pin low to select the chip loop() runs for as long as power is applied require you to manually call nd_now(). control over when the computer receives updates, but it does configure the joystick to manual send mode. #define H2D !(buttonInputs3 & 0x08) /* TMS */ #define H3D !(buttonInputs3 & 0x80) /* DMS */ #define H4U !(buttonInputs2 & 0x08) /* CMS */ #define H1D !(buttonInputs2 & 0x80) /* Trim */ #define S2 !(buttonInputs1 & 0x04) /* Pickle */ #define S4 !(buttonInputs1 & 0x08) /* Paddle Switch */ #define S1 !(buttonInputs1 & 0x10) /* Nose Wheel Steering */ #define TG2 !(buttonInputs1 & 0x20) /* Trigger 2 */ #define TG1 !(buttonInputs1 & 0x40) /* Trigger 1 */ #define S3 !(buttonInputs1 & 0x80) /* Pinky Switch */ Unsigned int buttonInputs1 // data read from SPI Buttons are muxed into shift registers, use the SPI protocol to read them You must select Joystick from the 'Tools > USB Type' menu

I found someone had already worked out what each of the five SPI wires, coming from the stick for the buttons/hats, should be connected to (for his Teensy 2) and provided the necessary code.ДЇollowing the 3.1 pinout I've wired Brown to Vin, Green to GND, Orange to SCK (Pin 13), Red to SS (Pin 10) and Yellow to DIN/MISO (12).Д¬ode: Select all | TOGGLE FULL SIZE /* USB FLCS Grip I bought a s/h Thrustmaster F-16 FLCS stick В and I want to convert it into a USB stick using a Teensy 3.1.
