I was able to put the
bee weighter project to some
tests. Some thoughts and insights from the process.
Three rechargeable AA batteries gave out 4V under the minuscule load the
electronics represent, even including the load from the internal voltage
regulator. I was expecting them…
In IEC 61131-3 compatible programming environments, string manipulation
have many inbuilt functions. Unfortunately, sometimes the routines are a
little bit hard to find. Even though it is possible to do a search through
available functions, just searching by name sometimes won't …
In my previous article I
have explained how to divide the memory into equal parts, so called blocks.
I have concluded that to utilize the entire memory, I could divide it into
256 blocks of 16 bytes or maybe even 128 blocks for 32 bytes. Having full
32 bytes seem like the overkil…
The AT24C32 EEPROM that comes with the DS3132 RTC module has 32kbit of
space, meaning it can store 4096 bytes or 4096 characters when using an
8-bit character encoding like ASCII.
To save some useful data on it, we need to divide it into equal blocks that
would contain the data. …
While researching the method to store the data into the electrically
erasable programmable read-only memory (EEPROM) I have found out the
problem is not as straightforward as I have previously thought. Consider
the following requirements:
Store the last N measured variables in o…
After a previous few
days of struggling to
get the Arduino Pro Micro 3.3V version to
get to sleep and wakeup I've
finally had an epiphany and got the desired result to surface up. It was
made possible by the massive amount of documented work I have finally
stumbled upon. Links ar…
When designing a circuit that is meant to run on low power, I have found
that is is a good start to choose a microcontroller board that is has a
lower base voltage level than 5V. The reasons are twofold. First, a lower
voltage means lower power consumed, period. Second, there are…
