What you have posted is basically a schematic.
I feel you have a question but may need to elaborate on you problem or information.
what is the source (internet link) for the diagram you provided?
Tell us more and folks here can help.
Yes, 0 volt is what is often referred to as “ground”.
But if battery powered or through many power supplied The 0 volt connection is not connected to ground (and thus is not earthed/grounded as is the metalwork on a mains powered device).
There is no problem in using the +5 V d.c. powering the SN754410 Vcc1 to also pull the two enable pins high - using a 10 kOhm pull up resistor as you suggest.
Remember also to ensure that the 0 Volt line to the SN754410 is also connected to the 0 Volt line for the microcontroller.

As IWP has indicated above, it is more a case of a documented feature.

Accordingly, no “fix” has ever been considered.
The usual recommended method for those who do have pauses of extended duration has been, as...
David Lincoln originally had a website from which all the code in the book and a lot of errata (I had provided a lot of feedback to the Vol 1 errata just as the book was released) was available to save time typing.
Lincsoft website has gone but the

If using the SERVO and SERVOPOS commands a byte variable is used and thus only values 0 to 255 are possible and accepted by the command. In this case there is no advantage in using the READADC10 - you would need to shift the value right (divide by 4) to use the top 8 bits.
lit using your...
Since neither circuit shows the SerialIn pin held low with a resistor I suggest a full schematic AND a photo of both circuits.
Photo needs to be straight down on the circuit and clear enough to trace the wiring.
If on a circuit board as opposed to a breadboard then photo of both sides of both...
Checking the com port as I mentioned in post 2 is normally only applicable when you have just installed the AXE027 drivers as the OP (Jack) had just done/mentioned.
PE6 appears to retain the com port number if started without the cable plugged into the USB port.
Hence thereafter it depends on...
You will need to ascertain the correct COM port number using Device manager (there is also an option in the PE but away from PC).
Typically for USB ports this can be COM 3 or 4.
EDIT: (Now at a PC)
In the PE6 From the Workspace Explorer at the left side
Under the Settings/ COM Port click the...
You will find some of my past information and code examples for the DS3232 here:
Hello Electronics Learner 123 (and others),
If once you have dropped the default IC onto your bread/proto/strip board you right click then you have the opportunity to select many specific IC's such as the PICAXE range and quite a number of other ICs often used with PIACXE projects.
It can pay...
