#Four pillars 4 2 serial ports code

There are other mappings available to other pins, but these two mappings actually work with the pin out of the nano every another important change here is that we now define hardware serial 2 as being the user 0 and the hardware serial 3 as being the user 2 And then we have here some more definitions of four interrupt vectors. Serial 3 max is now port max user, 2 alt 1, meaning we are now mapping out these two users to physical pins. The main changes here is that a hardware serial 2 max is now port max user, 0 default and hardware.

#Four pillars 4 2 serial ports code

We replace these two lines with some new code and again thats, not my code thats, the code kevin came up with okay. Now this file obviously defines the pin definition functions for the arduino and we are searching for two lines within that file, and here they are defined hardware 2, serial mux and define hardware 3 serial mugs, which are currently both set to none, specifically port max user 0. Now we can edit the dot, h, file and im just using here the editor. If anything should not work out as expected. The first thing i would do is save the original file here, so just copy and paste, and i call that dot h, dot or regional.

So the number of our 80 mega processor, of course, on other operating systems that may be a totally different path anyway. That version number might also vary in the future variants: nona 4809. Robot app data local arduino 15, so that might vary with the version of your arduino ide packages: arduino hardware mega avr 1.8.7. You have first to locate the pins underscore arduino dot h file for the arduino nano every on my machine windows, 10, its located under c users. We will make user 0 available as a serial 2 object and user 2 as the serial 3 object to do that. Tx rx antiques of the unused user 2 can be mapped here to digital 3 for rx and digital 6 for tx thats all a little bit over cross, but well, it is what it is anyways. Pin the rx and tx pins of the unused user 0 can be mapped here to digital 7 for rx and digital 2, 4. 3 is used by serial, that is, the usb port and user 1 is used by serial one and available on the tx and rx. I already revealed the big secret that the processor of the nano every the atmega4809 actually contains, four users of which only two are used. That honor belongs to somebody named kevin and i put a link to his blog in the description of the video. I didnt came up with the code for making two additional hardware serials available for the nano every within the arduino ide.

So, who do you think youre, zero and zero one are, however, i think you deserve the truth, even if it hurts and the truth is, there are four users living all together at base address, oh 800, so nobody really knows who your hardware serials are to learn That you will have to find serial 2 and 3. But you kept digging asking around in the nano every community and you were probably told there are only two hardware, cereals. Your cereal might have said honey wheres that coming from and your serial wants something along the lines of go to your arduino, ide and program, something. You probably already got suspicious after watching my second video about the basics of differential signaling with rs 422, where i told you that the hardware serials at their core are really use arts, universal synchronous, asynchronous receiver, transmitters card here link in the description, and so you asked Your cereal and cr1, are you really my hardware serials and their answers were probably quite evasive.
