If you are going to add an RTC then higher accuracy versions such as the DS3232 include around 256 bytes of battery backed RAM and if needed alarm settings with interrupts. The RTC battery keeps the time running and the RAM data retained which can avoid the need for external EEPROM or FRAM.
Yes, internally during a calculation the math is to 16 bits (0 to 65535)
even when the variable into which the final result is stored is defined as a byte (8 bits) so long as the intermediate math within a calculation does not exceed 65535 then the result is correct.
Tentatively a start. There is also the first edition.
However, beware that at the time of publication of the first edition I had reviewed the content for David Lincoln and initially he had a web page page for the identified addendum:corrections which has since been erased/gone.
1 the PICAXE manuals with the instructions (part2) and some basic circuits with example code (part 3).
2. The BASIC commands on line -that are more up to date and at the bottom of each webpage some examples...
If the circuit is:
1 only used by you
2. You do not use poke or SRF poke commands
3. The voltage does not exceed the PICAXE supply voltage
The program download pin is a bidirectional pin which the PICAXE firmware endeavours to limit to use as an input.
But if any code error using...
I found nhphantom had duplicated the post in the active forum and deleted the initial copy in the finished projects folders.
Had messaged nhphantom to advise done 👍
But neglected to indicate done here 😱
An error has been identified with the Programming Socket image in left-right orientation where the labelling for the 0V and SI terminals was transposed.
The corrected image is attached and should be copied into the PEBBLE/Images folder
I had a further look this morning. All there programming socket images except that highlighted by bogbean were correct.
Copy of the corrected image file for the terminal_134 which belongs in the PEBBLE/Images folder is also attached here (this copy edited in PaintShop Pro V9.01).
I will also...
At the top of the post you wish to link to there is
1. The day and time at the left
2 three icons at the right. From right to left they are: post number, bookmark and LINK/Share (the one that looks like 3 small boxes linked).
click on the LINK icon and a pop up appears with the address you need...
The RESET command is supposed to do the same as disconnecting and restoring power and according to the online Command reference this includes reset of all variables, the stack and “etc”. Refer:
That is not categoric as to whether non...
I had purchased and did some work with a DS3232 some years ago (2013). At that time I posted a guide to some RTC chips and a basic PICAXE program for the DS3232:

I have worked on projects before for submerged arc electric furnaces. They also operate around the 250 V. Those were 3-phase a.c. With 80 kA into each electrode for silicon metal and special alloys.
the mentioned project with 270 kA d.c. is an electro winning (EW) cell house for in effect...
