MichelKeijzers, The SoftwareSerial is useless for you, it h11l not transmit and receive at the same time. According to the H11L1 see datasheet an example circuit is:.
Your request has been submitted for approval. Any such audit shall not interfere with the ordinary business operations of Licensee and shall be conducted at the expense of ON Semiconductor. If you really need this full duplex all the time?
I put it in an answer for clearity. CL Too bad they didn’t make like 3 or 4 of them in one IC. The two cables on the right go to pin 4 and 5 of the MIDI cable I also switched them so that is not the problem.
Done I thought all datasheets for a part with the same ID would be similar. I thought I need a Mega, h11ll1 with two Uno’s it is also possible.
With the LED only for testing, the actuall pull-up is missing. Thanks about the Farnell Web site Copyright Lewis LoflinAll rights reserved. R2 and R3 form a voltage divider that prevents a proper high voltage; you have to connect the LED to 5V as shown in Transistor’s answer. Home Questions Tags Users Unanswered. As soon as you start using SoftwareSerial for a test, you are actually testing the SoftwareSerial itself.
serial – H11L1 opto isolator does not pass signal to Arduino (correctly) – Arduino Stack Exchange
However, I cannot receive anything and tried various circuits. Logic compatible output sinks 16mA at 0.
integrated circuit – Difference between H11L1 and H11L1M – Electrical Engineering Stack Exchange
If that’s OK then put the opto-isolator back in. Home Questions Tags Users Unanswered. The 6NA is single channel 10 MBd optocouplers utilizing a high efficient input LED coupled to a very high y11l1 integrated photo-detector logic gate with a strobable output. For MIDI, the differences between the clones do not matter.
