RS485 usage - charlesjabged - 11-02-2024
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 ?
RE: RS485 usage - admin - 11-03-2024
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 ?
RE: RS485 usage - admin - 11-04-2024
do you want send single command to read everyone register? or use one command to read all INPUT register?
RE: RS485 usage - admin - 11-05-2024
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".
