MBED, FlashIAP, TDBStore and STM32F4 internal flash
(Also: deriving your own class from SlicingBlockDevice) It wasn’t completely trivial to have all of them work together. Either the documentation doesn’t dig deep enough […]

You might remember that part of the power control strategy is to use a UVLO (under voltage lock-out). Well, here it is. It’s a simple […]
I’ve increased the sampling frequency to 23kHz and got much more stable results, stable enough to be useful. The image here shows the current measured […]
It’s a 3mm Perspex sheet. I was a bit suprised how flexible it is, I was expecting more rigidity. But it’s okay, I will (try […]
Still Spider ESC for the left motor, Blue Robotics basic ESC for the right motor. For some reason, I was unable to make PWM work […]
Built with wxPython. Communicate through the serial port of the PC with a Teensy making the gateway with the RFM69 radio module (and from here […]
In spite of some efforts, it’s still difficult to get a stable current measurement. As a reminder, on the prototype, the power is 25W with […]
As a reminder, the point is that the solar panel gives ~ 22V, while the motors are rated 14.4V. I thought a lot about it, […]
Bad luck, I started with a dead ESC (which I was convinced was working), and, since it was my first shot at PWM with ChibiOs, […]
I’m restarting the project and building a scaled-down prototype first to solve all the software problem on a cheaper model. I’ve settled on STM32F4(46) for […]
