I2C Hub 1 to 6 with M5stickC
-
@ajb2k3 Thanks for the answer. Where I can check the specs of various Grove ports on M5stack and M5stickC?
-
@smh17 if you look in the projects forum for the UIFlow roadmap discussion, I have them listed in a document. I am also going to try to make a video of it over the weekend
-
@ajb2k3 Could you link it here?
-
@smh17 link what? I am on a mobile phone at present
-
@ajb2k3 The page with the detailed specs of various Grove ports on M5stack and M5stickC.
-
@smh17 ah, its part of the free PDF I have uploaded
-
@ajb2k3 In the UIFlow book? In what page or paragraph. I haven't seen a specific section for Groove ports hardware specs, max power supplied on the line etc.
-
@smh17 There is only the pin outs and colour codes used on current deices and which ports are used by what unit.
Power specs are non existent at present, all I know from experiments is that when devices are connected to the hub, the stick suffers a "brown out"
Once I finish mapping out UIFlows blocks I can continue with my hardware experiments lime getting a ammeter on the port to find out when the brownout occurs. -
@ajb2k3 thanks for the answer. The missing of power specs is a serious omission, I hope M5Stack staff will add them. Do you have tried if using the hub with multiple devices attached and with USB connector of M5Stick attached to power source it changes something?
-
@smh17 yeh, the issue is the internal power regulator chip.
