Re: Hello, another Australian messing with programming toys.
Hi all, ... Been using disco boards for a few things, but have also started using the bluepill & blackpill. In the forum you will find a goodly quantity of posts on Blue/Black pills. I suggest spending some time on issues that have arisen due to these boards shipping with "clone" micr...

Re: GUI for serial data representation/control
A simple overview of my prior usage:

One of the great benefits, everything graphical is automatically accessible on the LAN by a modern browser; the webserver is just a free byproduct of using the tool.

Re: GUI for serial data representation/control
I would like to use a computer to see the graphical results and control how the system works. By this, do you think Adafruit's relevant products are what I need? Look into NodeRED. It is "free" and supports Win, Linux (Raspberry Pi, Orange), and IOS. https://nodered.org/docs/faq/interacti...

Re: hi flash usage compared avr8
I've choosed this IC due to the fact that I needed MCO/LSE output. I thought that flash and ram was plenty. I wanted a cheap IC. I don't need a bluepill or a F4 with float acceleration. The sketch above is mostly a I2C master slave implementation. I think that I'll go back to AVR for next revision ...

Re: GD32f103 and I2C
I did a bit of research and there are numerous reports of "strangeness" with the clone parts. A "blue pill" test suite: https://github.com/thanks4opensource/buck50 Clone die: https://zeptobars.com/en/read/GD32F103CBT6-mcm-serial-flash-Giga-Devices My own trip down cloneville: htt...

Re: MCP23S17 and BluePill Problem
Suggestion: Either fully nest the "if"s with "else" or better, use a switch-case structure.
Also, the Mega's int is int16_t and the STM32 int is int32_t, so adjust your parameter accordingly.

Re: AHT10 humidity sensor over Software I2C
it turns out my pcb humidity sensor thought experiment is more than just a thought experiment the real implementation of this concept is called *capacitive soil moisture sensors* :lol: https://www.mdpi.com/1424-8220/20/19/5644 https://www.aliexpress.com/wholesale?catId=0&SearchText=soil+moistur...

Re: AHT10 humidity sensor over Software I2C
the trouble with the analog world is it is really *analog*, equations and all are 'too perfect' for this real world around us,... But with Excel (or open-source similar) one can use solver and best-fit equations to derive rather simple bounded real-world models. uC just love flashed-based array tab...

Re: AHT10 humidity sensor over Software I2C
My apologies to blue-man for being lighthearted about a serious post, but ag123 is kind of asking for this... ... Thinking about this, has anyone got a decent idea how to do humidity as *analog*? after all stm32 has good ADCs ;) ... Must be a slow day for microcontroller questions, but you bring up ...
