Re: Ternary operator in calculation block?
True - but I've not had any issues so far. Also use if(.x) rather than if(.x !=0 ) - would be interesting to know if it actually saves any memory / or time. Must do a test...

Re: Ternary operator in calculation block?
One trick I use a lot - allows an imitation of the ternary operator in a lot of cases.
Boolean operations return 1 for true and 0 for false.
So use:
.v1 = (.v2 < 20) + 2. // 3 if v2 is < 20 else 2
.flag = (.v == 10) // flag true if v = 10

Re: Protocol j1587
Is that 'in tractor' or only on the bench?
If it's in situ - how long are the leads to the Nextion display? Interfence might be affecting that?

Re: Protocol j1587
Odd, how about waiting until the value changes from 128 - it sounds as though only the start byte is being received correctly. Can you just display (or send to uart) all the data received?

Re: Protocol j1587
I tried this - I've used a timer interrupt to add data if running as a simulation.

Re: Protocol j1587
I think the issue is - your code continually searches for 128 - and as soon as it is found - attempts to read 4 bytes from 'after' the 128.
These may not have been received yet...
So - one solution is wait for 128 to be found then wait until caunt_rx >= 4 and then display the values.

Re: Protocol j1587
Just done a quick test I did PutArray(.test, 10) LookForValue(.seek, 1, true, true) Where test = {x,x,x,128,129...) where x is any value and seek[0] = 128 LookForValue just returns 1 if the search value is found. (would the index (or -1) be better?) Then GetByte returns the 'following' data So in th...

Re: Protocol j1587
You can set a character in a string to 128.as above. Each character is a byte. You can set values using a number as shown or a character (in single quotes) or set the whole string.

Re: Protocol j1587
You can use LookForValue with a byte array or a string.
byte or string .val[1] // Looking for 1 value
.val[0] = 128
Then use LookForValue(.val, 1, ...)
