The storage media corresponding to the three boot modes of STM32 are all built-in chips. They are:
1) User flash memory = Flash built into the chip.
2) SRAM = The RAM area built into the chip is

Tornado uses WebSockets on Raspberry Pi and monitors serial Arduino communication
Basically, what I want to achieve is a canvas-based web interface to control an Arduino through Raspberry Pi. The use case is that a user navigates to raspberrypi:8080 to display a canvas. Then aft
Serial port – Windows UWP Windows.devices.serialCommunication.SerialDevice does not work
Is it just me, or is it a bug?
serialPort = await SerialDevice.FromIdAsync(Id); serialPort is always null, even if Id is not.
I need this to work. Now I just write very “fast and dirty”

STM32 serial optoth experiment
In experimental phase 1, the timer is timed for 1s to trigger an interrupt, and data is sent out during the interrupt.
The timer is set to 36000 frequency division, the period is set to 2000,
