I tried to like this video while watching it on my 'smart' tv. wasn't fast enough, so here I am to both like this video and subscribe because THIS was an awesome video and I learned something I hadn't even known I needed to know. Thank you.

I am in a situation where I need 68 temperature sensors that use I2C comms and only 1 SDA and SCL line, how would I know if it will work?

@fredchen9572 2 ай бұрын

Just try it from 2x sensor prototype, then 3, then 68...

couldn't the 'low-voltage' be reduced further by adding an extra resistor to the clock-line?

@DD-ci1iw Жыл бұрын

Great insights - but depending on what you are doing, the limit is even lower ;) Break-Out Boards usually give you the option to configure the used I2C-Adress by connecting a pin to GND, VCC, SLA or SLC. And that's another hard limit: You can only use 4 addresses for these kind of boards. If you want a fifth, you'll need to find another vendor who has preloaded his device with a different address or even offers some way to freely configure it beside the classic way of using 4 different voltage levels through an extra pin.

Then add a really big resistor in parallel, will solve the issue right?

@stark_energy Жыл бұрын

Adding any resistor in parallel will always reduce the overall resistance. To solve this I2C pull-up resistor problem, desolder all the built-in pull-up resistors on every device and place your own.

Why do people say i two c when it is "i square c" ?

@tanoryjakaperdana1419 Жыл бұрын

Coz its "inter intregated circuit" or some says IIC.. as you can see there are 2 pieces of I.. so its like 2 x I or I x 2 or I2, but not I square

It is even officially written I2C (Inter-Integrated Circuit, eye-squared-C), where the 2 is written as squarered web.archive.org/web/20210813122132if_/www.nxp.com/docs/en/user-guide/UM10204.pdf When teaching things to people i think it is important to be technically correct even in the terms used.

Hello! Do you know if it is possible to connect two displays, but SH1106 and with another library (I use Adafruit's)? The solution I have at the moment is to use 2 arduinos, but the expense would be higher.

This really helped in my understanding, but I was wondering (hopefully this is not a stupid question) but would this be considered analog multiplexing? And would this allow the arduino to communicate with 2 devices with the same MAC address at the same time?

@zacmilne9423 Жыл бұрын

I don’t think two devices with the same MAC address would work. I think the thumbnail for this video is misleading.

bluedot, you are awesome man! very nice presentation. the solution must be "TO SOMEHOW ATTAIN A EFFECTIVE RESISTANCE OF 1.5K OHM" you could try removing the pull up resistors in the slave(s) and adding a 1.5k resistor seperately

@jagadeeshdhoni438 4 жыл бұрын

if could maintain effective resistance @1.5k, then theoretically you can connect upto 128 devices
