Some have more hardware buffering which off loads the burden of datasyeet timing from the software. That is an absolute maximum value, check page 2 for actual supply current values or figure 6.

H11L1 opto isolator does not pass signal to Arduino correctly Ask Question.

All it would do is maintain a buffer of received data h11l1 is long enough to contain any expected messages until I could get around to reading it.

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.

I tried withand no changes But they need to be simple so as to be small and compatible with as many other Arduino libraries as possible.


Thanks for accepting my answer, but I do suggest you hold off for a day before doing so. Arduino Stack Exchange works best with JavaScript enabled. Sign up or log in Sign up using Google.

Thanks about the Farnell I will try this test again when I have the new Mega. The part is faster than needed with a good margin. The open-collector output will pull it down when turned on giving almost 5 V across the Fatasheet – D1 combination. Transistor 3 datassheet BenceKaulics There I see a supply current of ‘ Typ’ 1. The H11L1 was originally made by General Electric, but cloned by many other manufacturers.

This is a long way to go just to test the optical coupler. It will be these differences in chips which may turn out to make your high level code work differently better in some cases. When looping back, you are depending on the Atmel processor hardware to buffer up received data while datashest software is busy transmitting it.

I’m still looking around. Michel Keijzers 5, 9 25 Email Required, but never shown. 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.

datashet So, technically, H11L1M is the official name nowadays. The SoftwareSerial works better with higher baudrates. Because SoftwareSerial disables interrupts during transmitting and receiving, the lower the baudrate, the longer the interrupts will be disabled.

He can put the actual pull-up back when finished testing. Take a look at “Serial. Note, different Arduinos can use different processors with different internal hardware. This mW is an absolute maximum rating which means that if something goes wrong you can be sure that the device won’t blow up if the power dissipation is below this value. Post as a guest Name.

Home Questions Tags Users Unanswered. As soon as you start using SoftwareSerial for a test, you are actually testing the SoftwareSerial itself.

This is only the supply current into the VCC pin. If you really need this full duplex all the time? Also I tested before in an even simpler circuit that the signals from the H11L1 pass through pin 4 although inverted, which seems to be h111l1. R3 and D1 provide the pull-up.
