Re: Common Pitfalls designing a custom board?
It may be necessary that I have to prgramm the board without arduino. ... Arduino is really not well understood; it is just a bunch of JAVA code and script files with a little code manipulation (like automatic function prototyping.) The STM32 implementation is a set of wrappers around industrial-st...

Re: UART communication between two microcontrollers using DMA.
https://stm32f4-discovery.net/2017/07/stm32-tutorial-efficiently-receive-uart-data-using-dma/ USART in Ardhino land is interrupt driven and reasonably efficient, but some efficiency gain may come with DMA; I have seen that on some SPI I/O previously. As they say, "Your mileage may vary." ...

Re: A new small STM32L4 board
Hi All, I remember that a few years ago, there was a community effort to make a STM32F4 board in Blue Pill form factor. What is the latest information on that project? ... Origional thread: https://stm32duinoforum.com/forum/viewtopic_f_19_t_2633.html I think some members actually made bluepill size...

Re: Common Pitfalls designing a custom board?
In the old forum, a number of members were interested in their own boards. I seem to remember that a number of challenges were encountered and discussed. Feel free to explore: https://www.google.com/search?q=custom+board+design+site%3Astm32duinoforum.com Added: The origional Maple Mini was a 4-layer...

Re: How should I start learning Graphic Design?
Graphic design is a craft where professionals create visual content to communicate messages. By applying visual hierarchy and page layout techniques, designers use typography and pictures to meet users' specific needs and focus on the logic of displaying elements in interactive designs, to optimize...

Re: Porting Arduino´s library to Stm32
https://github.com/hcrest/sh2-demo-nucleo Note: This repository is similar to another one, bno080-nucleo-demo. That earlier repository used FreeRTOS and only supported the BNO080 processor. This one does not rely on any RTOS, features an improved library API and simpler HAL interface, and also supp...

Re: Serial output directly into NodeRED
... and the GUI is automatically accessible via browser on any LAN device; or Internet if you punch a hole in your furewall!
Consider that BT is also an easy transport for serialized data.
I have LoRa nodes but have not configured then for testing with NodeRED. So many toys, so little time.
