Work today

[Tyler Folsom]

I've completed software that does the following:
C6 gets speed from the cyclometer and sends it to C4
C4 passes the serial message to C3
C3 reads a desired speed profile, finds current position by parsing the serial speed, and sends desired speed to C2
C2 parses desired and actual speed, and uses a PID controller to activate throttle or brakes.

I plan to test software today from 10 to 3 at UWB. Want to join me? We are close to getting this sucker to move by itself.

That's awesome Tyler!! 

Let's get together soon. I would like to create a curriculum for my robotics class for highschooler using what I learned from the Elcano Project. 

Best wishes,

Budi -

I'm planning on working at UWB on Wednesday.  Want to join me?

Step 4 is close, but a roadblock has been inability of loading Arduino code to a Nano.  The serial line just seems to go away. Upload to a Mega works.  I've had this problem on 4 different computers.

Today I outlined Step 5, Obstacle avoidance.  Part of it will be installing the AS5043 angle sensor. The interface to C2 is over SPI and is not difficult. I bought bolts today on which to mount the magnets. I still need to upload the latest stuff to the web.

Are you using auto reset or manually resetting the nano?

[Tyler Folsom]

Danny -

I'm depending on the auto reset. On the Mac, the only choices for serial ports are bluetooth, which never works.

[Danny Dunn]

Sometimes autoreset on certain cables doesn't actually work and the commands get ignored and you have to manually reset the arduino. There's also a way to use an uno as a programmer and bypass the bootloader in a pinch.

Danny -

I've been looking for a way to bypass the bootloader. I was going to buy a Dragon, but it is on the chip level instead of the board level and the Arduino chips are non-socketed surface mount. The various non-bootloader options all seem to depend on the serial line, which is the same problem I'm trying to fix. 

Resetting doesn't do anything about giving a choice of a serial line that is really there.
