(Solved)M5StickC＋ToF:I2C bus error (19)

Koms

While using the M5StickC with the M5STACK-TOF-UNIT "Dostance Sensor" connected I receive the following error when running the simple block code on UIFlow

It used to work fine(using same code), but suddenly I receive the error.

Error:
I2C bus error (19)

Code(from UIFlow)

from m5stack import *
from m5ui import *
from uiflow import *
import time
import unit

setScreenColor(0x111111)
tof0 = unit.get(unit.TOF, unit.PORTA)



label0 = M5TextBox(8, 27, "Text", lcd.FONT_Default, 0xFFFFFF, rotate=0)


while True:
  label0.setText(str(tof0.distance))
  wait(1)
  wait_ms(2)

I try another code also, but I still recieved same error.
it looks like

tof0 = unit.get(unit.TOF, unit.PORTA)

part might has a probelm.

from m5stack import *
from m5ui import *
from uiflow import *
import time
import unit

setScreenColor(0x111111)
tof0 = unit.get(unit.TOF, unit.PORTA)





label0 = M5TextBox(8, 27, "Text", lcd.FONT_Default, 0xFFFFFF, rotate=0)


while True:
  label0.setText(str('Hello M5'))
  wait(1)
  wait_ms(2)

Any suggestions would be appreciated.

Hello @Koms

I am running your code just fine with UIFlow firmware 1.7.3 on my M5StickC.

are you using the latest UIFlow firmware?
have you tried another cable? (I get error 19 when I disconnect the unit)
is the cable plugged in all the way?

Thanks
Felix
