RS485 usage

[charlesjabged]

I just received the keyboard and i am trying to read button state with modbus. I try to use this: https://www.kincony.com/forum/attachment.php?aid=2240
but it is really unclear to me.

I try coils, inputs reg, and holding with:
1 stop bit, no parity, 9600 baud.

I have 3 others devices that work well on the same modbus line ( with different MB address ).

Can you help me with the correct way to poll button status ? (i will do a request every 1sec).

thank you in advance.

I just updated this firmware using your tools. How can i check the version to know if the update is correct ?

[admin]

download this firmware file: https://www.kincony.com/forum/attachment.php?aid=6311
after download, unzip, just download BIN file to ESP32.

That exactly what i did. Then, i can connect to the wifi AP and go to the web interface. The software version is: 1.0.6. but the file linked is 2.2.6. 
Is there a why to check if the new firmeware was really written on the targeted device ?

Just to let yo know that, after multiple try, i was able to update the board successfully. Now, i am able to read 35 coils. The only problem is that the coils 1 do not correspond to input 1.

From 4 to 8, inputs seems to be reversed. is it normal ?

[admin]

do you want send single command to read everyone register? or use one command to read all INPUT register?

tested with KCS firmware, enabled rs485 modbus as follows, INPUT1 (key1) is no problem. see the photos.
INPUT 1-35 begin with RS485 register 0
   
   
   
   

tested with key4 ,also is well.  bit "0" means "pressed".
