Progress is slow as I’ve been busy with other things. I’ll probably be 50% finished with the Arduino Nano Every book in another week. I think I’ve been spending too much time answering Quora questions, which not only doesn’t get the book written but also doesn’t make me more knowledgeable as the questions are too …
I basically stopped and cowered because of COVID-19 and my wife and I being high risk. However I’m now finally back writing again. I’m hoping to get the Arduino Nano Every book done by the end of June. Examples programs will be basically to show new features and how it differs from the older AVR …
The ATmega4809 organizes I/O registers by module and puts all the registers in C structures. The older AVR microcontrollers have a flat organization. For instance, take the Data Direction register for port B. In the ATmega328P this is simply defined: #define DDRB _SFR_IO8(0x04) This puts the register at location 0x04. In the ATmega4809, all the …
Update: individual Arduino Nano Every boards have returned. https://store.arduino.cc/usa/nano-every But the headers are not attached so you have to solder them on, or go the Amazon route which appears to still have them with headers mounted. Posted in February — It looks like Arduino has discontinued sales of individual Nano Every boards. They are now …
I’m pondering the direction of the new book covering the Arduino Nano Every and the ATmega4809 microcontroller. There are considerable differences in the implementation of this board compared to the ATmega328P based boards like the Arduino Nano and Uno. My first book, Far Inside The Arduino, covered using the Uno (and similar) board directly controlling …
No book progress this month as I’ve been caught up in the holidays. Also, just became a grandfather, so there is that as well. I’ll attempt to get the next book finished in January. Happy holidays!
I heard about, purchased, and read this fascinating book Track Changes: A Literary History of Word Processing, by Matthew G Kirschenbaum. It tells the history of word processing on computers, but primarily from the viewpoint of the writer. This is a scholarly work with 80 pages of footnotes! Using a computer instead of a typewriter …
One thing I have been doing is answering questions on Quora, particularly questions about the Arduino Uno and related boards (using the ATmega328P or ATmega2560) when the questioner would benefit from a little knowledge of what’s “Far Inside”. Perhaps people will read the answers, see my bio blurb, and seek out Far Inside The Arduino. …
I wrote this title to be ambiguous. I’ve been busy with personal things so slow progress on writing. I’ve just started back up on the Arduino Nano Every (ATMega4809) book. The needs of the Arduino people to have this board as compatible as possible with the older Arduino Nano has made this a surprisingly difficult …
There is a transposed const and * in the section Using the EEPROM. The code snippet should read: struct MYEEPROM { byte aByte; word aWord; word aSecondWord; } * const eeprom = (struct MYEEPROM *)0;
