Hello i want to read rs485 wind direction sensor.
How to get data from this sensor. Instruction is guery frame is on this page :
https://wiki.dfrobot.com/SKU_SEN0482_RS485_Wind_Direction_Transmitter_V2
but i dont know how to write and get answer in UIFlow :/
Need help :> one week no clue how to get info
Hello,
I have core 2 and i use port A to connect PB.HUB.
Then i connect to the Hub wind speed meter and hall unit.
Hall to ch1 and wind speed meter to ch2
I use uiflow with code in picture.
So when i send this program to core 2 i get false readings. Its like i get read from both at the same time. when i delete one digital read second works fine.
Ehhhh
Anotcher anomaly i use Pb.Hub and i connect wind speed meter to ch0 and Hall sensor to ch1.
I use digitalRead from ch0 to read IO 1 for speed meter and digitaRead ch1 read IO 1 to read hall
AND signal is mixed for both. I get readings from windspped meter when i use hall and hall reads inputs when i blow to windspeed meter. When i use both i get stupid info :/
Ok i try to connect this way :
core 2 -> Pb.hub -> hall sensor
and i cant in UiFlow to set the hall sensor to pb.hub i get only grove.
See picture
And another wired thing - when i use Pa.Hub with ENV III i get temp and humidity ok but pressure is -4826090,3. I cant get negativ pressure :>
When i connect direct to core 2 i get right value.
I use UIFlow
i get weard readings like -482827.3 when connect to pa.hub but connected direct to core 2 ewerything is ok

Hello,
i get a problem with Pa.HUB i connected to it ENV.III. I get Temp and Hum ok but i get -482827.3 for pressure.
What is wrong ??
Hello,
i cant connect Hall sensor A3144E to Pa.Hub 9548AP on my M5Stack Core 2.
What is a solution to use it ??
