I had a little confusion regarding how to flash a firmware into the maple mini board and, more in general, on the STM32 family microcontroller. Normally I have always used an st-link V2 usb pen for both upload a new firmware and debugging purpose, but a friend ask me “why we can’t use the USB connector directly without any other adaptor?” Digging a little bit I have found that STM32 micro do have an in-ROM bootloader to update the firmware, but it is not the same software on every stm32 device ( STMicroelectronics AN2606 which describe the stm32-microcontroller-system-memory-boot-mode).

Naturalmente la ricetta non viene eseguita alla lettera, ma con qualche personalizzazione. Il consiglio è leggere diverse ricette presenti in rete e, come dire, seguire i passi che meglio risuonano con i gusti personali del momento! Sicuramente le ricette della cucina tipica seguono il principio che c’è più di un modo per essere preparate (There’s more than one way to do it).

In the beginning of this year I restart one of my oldest hobbies, ham-radio. It was not my intention to invest a lot of effort into it so I brought two vertical antennas, one for the HF and the other for VHF and UHF. HF antenna is a Falcon D-original OUT-250-B (10-80mt) and, let’s say, it works. Nothing special about it, apart from it has a reasonable price. I think it is the right antenna when you don’t know what you are looking for.

C++ notes To expand the concept of Create a catalog of static functions with also add object’s functions. Create two class with both a suspend() function. The first class will be used as static only, the second one will register each object instantiated. Calling the suspend() static function of the second class will in turn call all the suspend() function of each object. A working example (available on github). /* Callback object functions in C++.
