I just managed to setup a local pxt-microbit and jacdac environment. It looks like the servo module only response to one of the enable packets sent to the servo. trace.jd.txt

xmeow commented 8 months ago

The problem is possibly caused by the firmware missed the timing to receive some of the jacdac packets. This will only happen when both servos are powered off, and the dedicated position is different from the current position.

And this can be reproduced in the dashboard by following steps:

  1. download following code to microbit 
    
console.log("Servo test")

basic.showIcon(IconNames.Heart) // basic.pause(100) // modules.servo1.setEnabled(true) // modules.servo2.setEnabled(true) // basic.showIcon(IconNames.SmallHeart)

input.onButtonPressed(Button.A, function () { modules.servo1.setAngle(0) modules.servo2.setAngle(0) })

input.onButtonPressed(Button.B, function () { modules.servo1.setAngle(90) modules.servo2.setAngle(90) })

2. Reset the servo module from dashboard. Make sure both servo module is powered off. **This is important**
3. click button B, both servo service will try to power on the servo, then move to 90.

Only one of the servo may got powered on or moved, and there is massive RX t/o error in the log.

Here is some codalLogStore dump:
