feather-stm32f405: I2C not working

[deadprogram]

I finally acquired an Adafruit feather-stm32f405 board. Flashed it with the latest TInyGo dev branch. The MPU6050 example from here does not run correctly: https://github.com/tinygo-org/drivers/blob/release/examples/mpu6050/main.go

It only returns zero values...

@ardnew any thoughts?

Did you try the dev branch before #1557? It may have broken things.

Same behavior in current release branch.

I wonder if the change similar to 66f7683 would address the issue I have with the stm32f405? Seems like a good chance it would.

OK I can confirm that now with 66f7683 in the dev branch that if I add a time.Sleep(100 * time.Millisecond) to the MPU6050 example as suggested by @kenbell this works:

func main() {
	machine.I2C0.Configure(machine.I2CConfig{})

	time.Sleep(100 * time.Millisecond)
	accel := mpu6050.New(machine.I2C0)
	accel.Configure()
...

This has been released with v0.17.0 so now closing. Thanks!
