Original Address-Https://www.arduino.cc/en/Tutorial/DimmerLight dimmerThis example shows how to send data from a PC to the Arduino/genuino Development Board to control the brightness of an LED. The data is sent in separate bytes, with a range of 0 to 255 for each number. The program reads these bytes and uses them to set the brightness of the LEDs.Hardware requirementsArduino or Genuino Development Board Led 220 Ohm ResistorSoftware RequirementsProcessing or Max/

2,The LR value will be set based on the processor mode and the stack used (of course, the configured LR value will be re-applied to the

1) MSP (single-host Edition)MSP has many functions. In fact, it is mainly used for WBS (work breakdown structure). The task management mode is still the duration type, that is, the task is defined by the start and end time. For large projects, if the project organization is managed hierarchically, my project plan is only divided into the granularity of Group tasks. The team leaders themselves use

After the OS is changed to Vista, the original rose2003 cannot be used. I found a lot of information on the Internet, but not much useful.
Later I saw that the new version 7.0 supports Vista, but it was hard to find it.
Today, I finally got it. The installation was successful. Finally, we can use Rational Rose for analysis.

, PC, LR, R12, and R3-R0 are automatically pushed into the appropriate stack by the hardware: if the current code is using PSP when an exception is returned, press PSP to use the thread stack. Otherwise, press MSP to use the master stack.
Remember that the CPU will always use the primary stack (MSP) once the service is interrupted ).

Chaincode Invoke is a trading proposal, and then performs a modular process (endorsement, consensus, validation, submission). The structure of Invoke is a function and an array of parameters.

all refer to this timer, not the personal computer) the value of the timer after the reset is critical. In "The definitive Guide to ARM cortex M3" (Simplified Chinese), we know that the first thing that ARM cortex does after leaving the reset state is to read the values of the following two 32-bit integers:
Remove the initial value of MSP (Main Stack Point) from the address 0x00000000
The initial value of the PC is removed from the address 0x00000004

This algorithm is a reverse thinking of forward maximum matching. If the matching fails, the first word of the matching field is removed. The experiment shows that the reverse maximum matching algorithm is better than the forward maximum matching algorithm.
