Hi.

The link of the ChibiOS submodule appears to be broken or something. After cloning the e-puck2_main-processor repo, the ChibiOS directory is empty and, therefore, the project cannot be built in eclipse. As an attempt to fix this, I went to the referenced url and searched for the submodule's commit, however, I could not find the f57f665 commit (?). As an alternative, I cloned the master branch of the referenced link and used it to replace the empty ChibiOS folder inside the cloned e-puck2_main-processor repo. Nevertheless, the building process still outputs some errors regarding files within the ChibiOS folder.

The repository's snapshot available at the e-puck2 wiki is working, yet, the version of the firmware is not the latest one (for instance, the selector ops in the snapshot's code appear to be different than the ones explained in the wiki).

I do not know if I am missing something here, but where else could I get the latest source code of the main processor firmware?

In advance, thank you for your attention.

Hi,
I spent some time scratching my head on why the robot was not moving, even tho I kept calling left/right_motor_set_speed(vitesse) in my main loop.
I'm not sure if the comment on line 314 meant that the problem was supposedly fixed or if it's known, but it seems that the problem is still present.
My workaround was to call X_motor_set_speed(vitesse) only if there is a change from the previous state.

I would suggest doing the same inside left_motor_set_speed(vitesse) and right_motor_set_speed(vitesse) unless the root cause can be addressed, as I couldn't find anything about this issue in the documentation

void motor_set_speed(struct stepper_motor_s *m, int speed)
{
[...]
    uint16_t interval;
    if (speed == 0) {
        m->direction = HALT;
        //Resolves a problem when the motors take about 650ms to restart
[...]
