Great tutorial. Thank you so much!

[@ozprofesorsky5062]

Excellent tutorial thank you! Between this and recently reading a datasheet on the atmega16u2 I feel like I actually understand how to make this work. I really appreciate it. Thanks.

[@BinderTronics]

Glad it helped!

very usual. thumbs up from me. the RX methods work great, The TX methods are not very good fast though, i ended up using the same buffering principle from RX for the TX functionality allowing me to transmit arrays without waiting for each bite to send. a very useful informative video set me in the right direction quickly. thanks

[@ludovanginderen6850]

you are GREAT ,thanks for your videos

[@reshadrei1788]

bravo! very informative, please make an assembly version of this video. thanks

[@BinderTronics]

Thanks but no on the assembly. I prefer to keep my sanity.

[@sonus89]

I love that UPPARR at 30:21

[@BinderTronics]

Brain LAG.

@@BinderTronics What is your mother tongue sir? ( Btw. I love your videos

[@BinderTronics]

You are probably not enabling global interrupts. Afrikaans. You are hearing a heavily suppressed version of the accent.

An example of 9-bit configuration is used for MDB communication protocol. It is used in vending machines, and I don't know who decided it is a good idea to use an extra bit...

[@BinderTronics]

Had a look at the specification sheet. Interesting serial protocol. Using the 9th bit to determine data direction. That makes 1 so far.

Very helpful!!!

[@BenomraneAbderrahmen]

I would like to express my gratitude for the valuable assistance you have provided through your videos. Currently, I am working on an academic project that involves the Atmega328P microcontroller, where I am required to use two UARTs - the native one, as well as other pins that function as UART. Can you please guide me on how to accomplish this task?

[@BinderTronics]

Option 1: Use Arduino software serial lib. Option 2: Use a Atmega328PB that has 2 native serial ports.

[@BinderTronics]

Option 3: The big daddy in the line up. ATmega2560

[@BenomraneAbderrahmen]

If i use the Arduino Software Serial lib to communicate with the microcontroller, then i must use the Arduino IDE to write and compile my code ? right ? . However, if i use Atmel Studio to write my code, then i'll need to create my own library to communicate with the microcontroller.

[@BinderTronics]

@@BenomraneAbderrahmen You are not constraint to the IDE. Atmel Studio supports Arduino projects. Simply create a port of the soft serial lib in C. gprivate.com/64bzv second link looks promising.

WHAT SOFTWARE DO YOU USE WHEN WRITING THE LETTERS IN THE UPPER RIGHT CORNER

[@BinderTronics]

putty. any serial terminal will work

[@fisikamodern5209]

can MAX232 work with putty software?

[@BinderTronics]

Get yourself a CH340 or FTDI USB to serial converter. MAX232 (RS232) runs on -12V to +12V. If you want to use a MAX232 you are going to connect MCU to the MAX232 turning the into a RS232 line. Then you need a RS232 to usb serial converter. THE CH340 or FTDI is a direct connection to between the MCU and PC.

[@BinderTronics]

This is what you looking for and is the same board I am using. www.waveshare.com/ft232-usb-uart-board-micro.htm

[@pabloa_e]

Hey thanks for your video ! Very helpful. Just a question, how can I save the buffer receive when using uart_read() and save it into a variable correctly ? Because I try to make a comparison like that : uint8_t val = uart_read(); if(val == "t"){ // here I want to do something } The if isn't trigger. What should I do to compare char or string to the value returned ? Edit : Ok I found it, I have to use 't' instead of "t" my bad haha

[@BinderTronics]

Glad you got a solution.

[@pabloa_e]

@@BinderTronics Yes thank you, took me ages to understand the UART communication haha. Your video help me a lot !!! My project can succeed Continue like that 😁

[@adityaray203]

Can we use TXC0 from UCSR0A status register instead of using usrt_tx_busy?

[@BinderTronics]

The bit description of TXC0 is not clear. I see no issue with using it but you will have to validate what the bits mean.

[@danielbycinskij3685]

Is this tutorial is also compatible with dmx receive?

[@BinderTronics]

Going to assume you are talking about Digital Multiplex. Unless your DMX controller outputs UART, RS485 or RS422 then no.

[@sadziooo6194]

Which terminal is used to check the output?

[@BinderTronics]

Putty

[@imrichmorvay2227]

this is too complicated arduino have SerialPrint and thats it

[@BinderTronics]

The joke is. This is what is sitting behind the abstraction of arduino. All this just so you can use SerialPrint.
