ACSSR I2c control

[ajb2k3]

First off, let me say " I Haz Dumb"!
I'm trying to run the ACSSR over I2C Using UIFLow and I can not for the life of me workout how to trigger the SSR. has anyone worked this out yet

Hello @ajb2k3

first of all make sure when the ACSSR powers on the internal RGB LED blinks red (=I2C mode). If not, follow the instructions here to change mode. (Section Usage/Communication protocol)

Then use something like below to first scan the I2C bus, set the proper slave address, read the version and then toggle the ACSSR every second.
Note: I used an M5Atom for this example.

or from the Micropython tab:

from m5stack import *
from m5ui import *
from uiflow import *
import i2c_bus
import time

myToggle = None

i2c0 = i2c_bus.easyI2C(i2c_bus.PORTA, 0x00, freq=400000)
print(i2c0.scan())
wait(1)
i2c0.addr=(0x50)
print(i2c0.read_u8(0xFE))
myToggle = False
while True:
  if myToggle == False:
    myToggle = True
    i2c0.write_u8(0x00, 0x01)
  else:
    myToggle = False
    i2c0.write_u8(0x00, 0x00)
  wait(1)
  wait_ms(2)

Thanks

Thanks mate, I didn't know you had to set the slave address, that explains why noting is working.
