I'll be doing the prototype soon and I'll get some pics, but the final versions will be specifically ordered metal joystick boxes that cost a ton, so the final stick price will be above $500 USD, if not a LOT above $500 USD, so I don't even know if I'll do all 6. I may just do one to see if it sells, then work on the next one etc.

If you're in a rush for LS-30s, I recommend the forums at KLOV as people list them every few months or so, about $200-300 for a pair, that's how I got my six.

Thanks!

That looks very nice. I ordered some parts, and I am going to build one myself as well. Time permitting.
(and yes, have the same questions as you have )

Search any tutorial on Google to see how to do this. For programming the Blue Pill I used a STLINK V2 programmer, but you have several alternativos. Again use google to search a tutorial to see the process. I provide the. ino file to program the microcontroller. Always double check your circuit before connectijg to power.

For debugging I used a logic analyzer+function generator Digilent Digital Discovery, that can generate inputs signals (CLK, LOAD) for the STM32 and read the DATA and Quartus Signal Probe III for FPGA in debugging. But for final users a cheap STLINK V2 programmer is all the needed.

https://github.com/stm32duino/wiki/wiki/Upload-methods
See the section: STM32CubeProgrammer

You need to install (tested on Windows 10):
[*] STLINK v2 drivers: https://www.st.com/en/development-tools ... nk009.html
[*] STM32Cube programmer: https://www.st.com/en/development-tools ... eprog.html
[*] Arduino (tested with 1.8.19)
[*] STM32Duino: https://github.com/stm32duino/wiki/wiki/Getting-Started

Mi Arduino settings for Blue Pill:



It is important that you are clear about all the necessary software and hardware properly installed before you attempt to test the adapter. Take a good look at how it is done in a guide, there are many sources of information where it is explained in detail, I am sorry that I did not include all this information but I do not have time available for this, there are very good resources that already explain it perfectly.

VERY IMPORTANT: DON'T POWER THE BLUE PILL WITH THE MICRO USB AND THE USERIO CONNECTED TO MISTER BOTH AT THE SAME TIME, BOTH SEND 5V TO THE BLUE PILL AND CAN DAMAGE YOUR USB PORT. YOU NEED POWER FOR THE BLUE PILL TO BE ABLE TO PROGRAM IT WITH THE STLINK V2, USE ONLY ONE POWER SOURCE.
WHEN YOU USE THE ADAPTER IN A NORMAL WAY (WITHOUT THE PROGRAMMER CONNECTED TO THE BLUE PILL) THE POWER SUPPLY (5V) COMES FROM MiSTer THROUGH THE USERIO PORT VBUS PIN, THE BLUEPILL ALREADY HAS A BUILT-IN DC REGULATOR TO GET 3.3V FROM THAT POWER SUPPLY.

Based on the STLINK V2 that you own:
