@JackZ I don’t think that’ll work; from the sounds of it, if you send: Message ID=1, payload 0x5F intended for instrument A Message ID=2, payload 0xB2 intended for instrument B Both instruments will receive *two copies* of both payloads. If you tell instrument A to ignore payload 2, you still have ...

That's a good idea! I'll try it with si commands.
Thank you!

When you have more than one instruments that receive messages from the same hardware_id, the instrument gets the same message times the number of instruments. E.g. If you have instr A with id = hw_message_port_add("ARDUINO_MEGA2560_A", new_message) and instrB with id = hw_message_port_add(...

Hello, As Sling said there are some bugs regarding si variables. I found the following problems: 1. When you use si_variable_create and you initialize the variable with a value, that value isn't returned from the xplane plugin. So when you subscribe to this variable you always get 0. var_id = si_var...

If you write 88888888 to test a display, then you should find the previous values to write them back, when the test is over. And writing on 3 daisy chained MAX7219 simoultaneously (6 displays) doesn't always work properly on AM.

I had the same problem with those 3 pin switches so instead of using: function switch_callback(position) print("Switch pos " .. position) end hw_switch_add("ARDUINO_MEGA2560_D_D4", "ARDUINO_MEGA2560_D_D6", switch_callback) --ON/OFF/ON switch I used: function dn_switch_c...

It would be useful if you could include a function for Display Test and Shutdown operations for the MAX7219 as described in the datasheet. It is similar to the brightness function but with an other address part. Please have a look at it!!

When updating a string dataref with fewer characters, the remaining characters in the old value of the dataref are not deleted. ex. If the dataref value is "abcdef", when I update with the value "XYZ" the result is "XYZdef". value="abcdefg" xpl_dataref_write(&...

Thank you so much! Keep up the good work guys!!

Thank you for the replies, sorry for the code block! There are other functions that might be called and should update the same dataref at different indexes. Even if I update multiple values only once per function, some values are updated, but others not. You can try this code: function updateArray()...
