Arduino for STM32

If you are hung-up on the "blue-pill", you are going to need to validate several know good boards from a number of boards you ordered. But, even at $2 per board, you are going to spend $20 for 10 boards and know that a percentage will go to the trash. Depends on what you use them for and ...

Updates: 1. I opened my hardware up, and I am using 30K pots, not 400K as stated before. My mistaken. 2. While I don't have any noticeable wobbling on my Windows laptop with all my changes, I have lots of wobbling on my Raspberry PI, mainly on the second pot. I wonder if this is due to the PI's powe...

I don't know how exactly to check if USB is finished transmitting, though I suppose I could just add a simple delay(13) (I know that the transmission takes about 12ms). However, the cost of waiting for USB to finish transmitting is that I introduce more latency, and so I wouldn't be able to afford a...

1. Pulling down the other pins doesn't seem to do anything in my testing. 2. In further testing, turning off interrupts during acquisition doesn't seem to matter much. 3. I found that the limiting factor in my project is USB sending, which happens in the background. That means that I can increase th...

That's a nice idea. Disabling interrupts for the read does seem to help a little bit. But doesn't solve the problem entirely. UPDATES: 1. I've also noticed another weird thing: there is a kind of "afterimage" from the first pot reading. I did this experiment: keep pot 2 unmoved and turn po...

In my USB paddle game controller project (https://github.com/arpruss/paddlecontrollers), I was initially getting a lot of wobble in reading the controller pots (which were 400K pots): the paddles in the Pong game were shaking very visibly. This seems to be especially bad when the paddles are plugged...

Is there a way to get the Arduino IDE with Roger's core compile to a .bin file that could be uploaded to a device by a user using the STM Demonstrator, without bothering with a bootloader?

And full build instructions are here: https://www.instructables.com/id/USB-Pa ... ontroller/

I've change the firmware so that in single-joystick mode (where X=paddle 1 and Y=paddle 2) it emulates a Stelladaptor.

I also made a game very close in gameplay to Pong in pygame for this.

I made 3D-printable Atari-style paddle controllers that either show up as a USB joystick (X and Y controlled by two paddles), or two USB joysticks, or an absolute mouse. Firmware is here . It needs the latest version of my USB Composite library and the libmaple-based core. Printable files are here ....
