Jun 2 ’17 at A ” ; mySerial. When SoftwareSerial is used with a very low baudrate ofthen it could even disturb the receiving of data of other hardware serial ports. R3 and D1 provide the pull-up.

Just doubting if the MIDI functionality will work since it will be functionally similar as now: Take a look at “Serial. If I check the data sheets, I see some different values, but for me it is unclear to know if these will affect the usage for MIDI For MIDI, the differences between the clones do not matter.

To be honest, I have a Mega, but I don’t ‘dare’ to use it, since that one is now on a breadboard circuit that I’m for sure knows it works and by disassembling it, I’m afraid I don’t have any working solution.

It will be these differences in chips which may turn out to make your high level code work differently better in some cases. A couple of mA that is normally needed. The SoftwareSerial works better with higher baudrates. The part is faster than needed with a good margin.

So far I’m really a beginner, just breadboarding and playing and learning electronics. Sign up using Email and Password.

Home Questions Tags Users Unanswered. Because SoftwareSerial disables interrupts during transmitting and receiving, the lower the baudrate, the longer the interrupts will be disabled.

Sign up or log in Sign up using Google. Jun 25 ’17 at All it would do is maintain a buffer of received data that is long enough to contain any expected messages until I could get around to reading it.

Also, if I need dataxheet get them from an online webshop from the Netherlands, euro shipping cost is added, making like 10 pieces of H11L1 cost even more. Link the datasheets you are datashret to. CL Too bad they didn’t make like 3 or 4 of them in one IC. H11L1 opto isolator does not pass signal to Arduino correctly Ask Question.

May 19 ’17 at Some have more hardware buffering which off loads the burden of serial timing from the software.

The lower the baudrate, the more trouble you get. Fairchild adds an “M” suffix to optocouplers in a white package which has properties different from those of black packages. Perhaps I should add. This is far above the normal operational conditions. Datsheet when I’m off sending data I will not miss any data being sent to me. JamesWaldby With lower baudrates, the interrupts are disabled for longer time.

I have made a very basic test circuit for the opto coupler H11L1 ‘similar’datasheet: Almost everybody also calls it “H11L1” clones with different names, like the PC, turned out to have not been as successful.

When I go to a nearby shop there aren’t manyI have to pay 2 euro per piece, for AliExpress it’s 10x less, also they don’t have the exact same type. Then you are depending on the Arduino serial libraries to get that buffered data if there is any after the it was already received. I am not sure how the Arduino serial libraries are written. Use one of those to do tests datasheeg a serial port. There is an alternative, the AltSoftSerial Library.

The H11L1 inverts the signal, and it seems I had to connect the output of the first H11L1 to the input of a second and now it works.
