Dominik Posted December 30, 2021 Report Share Posted December 30, 2021 Hello, I'm trying to read the offset 0x034E - COM1 frequency, using lua, Here is the code while 1 do file = io.open("test.txt", "w") ppp = ipc.readUW(0x034E) file:write(ppp, "\n") file:close() ipc.sleep(50) end The loop writes the value of this offset to the file. The value of this offset is 6194, com1 frequency is set to 118.050 It reads this value wrong and I don't know where I went wrong. Please help. Dominik.

Dominik Posted December 31, 2021 Author Report Share Posted December 31, 2021 I think I found a solution to the problem, I have to use string.format("%04X", value) Link to comment Share on other sites More sharing options...

A frequency of 123.45 is represented by 0x2345. The leading 1 is assumed. Link to comment Share on other sites More sharing options...
