Re: UNO SCADA SPI Prescaler question
Hi Peter, Have you tried loading the newer bootloader onto the clone Uno? See https://www.instructables.com/How-to-Upload-Bootloader-to-Any-Arduino-/#:~:text=Here%20are%20the%20couple%20of%20different%20possibilities%20in,Pic%20represent%20Uploading%20bootloader%20from%20Uno%20to%20Nano For example?...

Upload problem on Arduino Nano 57600
After the latest definition file update for the Arduino Nano (57600) - the command line for AVRDUDE is incorrect. H:\>"H:\AVR\avrv5\batchfiles\..\bin\avrdude.exe" -p m328p -P 57600 -b "H:\Flowcode1.hex" -c arduino -D -U flash:w:"" avrdude.exe: invalid baud rate specified 'H:\Flowcode1.hex' Should be...

Re: UNO SCADA SPI Prescaler question
The documents aren't very clear? I'd guess the values correspond to prescaler of 4, 16, and 64 (ie clock of 16Mhz (FOsc?) / prescale) - the firmware calls SetPrescaler in the CAL SPI. (Docs don't specify here either) Edit - however experimenting in v8 (see below) - calling SetPrescaler with (2,4,8 e...

Flowcode Exchange
drum roll....... We are pleased to announce the launch of www.flowcodexchange.com This is a (independent) site to allow the sale of Flowcode components and programming expertise. Currently there are a few components - but we will be adding more over the next few weeks. These are components that don'...

Const to Flowcode - Copying from C to FC made simple
Another project. Again based on an experiment I did on making a Flowchart viewer. This copies const or #defines from C to Flowcode - for me one of the problems with flowcharts is the hard-coded values. Easy to write but hard to maintain at a later date. This copies const declarations of the form: co...

MacroSwap - Easy macro copying between flowcharts
A project of sorts. I'm not sure this is the right place for it - as it's really a PC app. This app lets you transfer macros from one Flowcode program to another. It's quick and easy to do multiple macros in one easy operation. Simple load the 'source' flowchart by clicking on 'source' and a target ...

Re: Sensor presur hx710
Take a look at the Arduino library for the HX711 (I chose first in the list by Rob Tillaart)- it looks fairly straightforward. It should work AOK with the HX710B.
I don't have a sample to work with - but it should be possible to get it to work with Flowcode.

Re: AT TINY 85 i2c non compatibile display SSD 1306
Thanks Ben, The single buffer gave a bit of a speed boost - but whether it's worth an upgrade to the component? I think it's worth having a version that will work with smaller MCUs (so without the full font support) - I just used an 8x8 font (scaling would be easy enough to add too). Does this need ...

Re: Tips and tricks for saving RAM
Good luck.
The other thing to watch is components used - some (displays/sd for example) can use a fair bit of memory for buffers.

Re: Tips and tricks for saving RAM
Hi Oscar, The compiler settings just control the size of the code - the RAM use depends on the number of variables and also depth of procedure calls. So the things you can do - use the smallest possible variable size for data types. Use loops with your own variable as the index. Flowcode will genera...
