How to see the program occupying STM32 flash and SRAM from the Keil compilation result-EEWORLD

Program Size: Code=114956 RO-data=20528 RW-data=808 ZI-data=702360

FromELF: creating hex file...

Build Time Elapsed: 00:00:05

From the compilation information above, we can see that the FLASH size occupied by our code is:
135484 bytes (114956 +20528), and the SRAM size used is: 703168 bytes (808 +702360).

Here we explain the meaning of several data in the compilation result:
Code: Indicates the size of the FLASH occupied by the program (FLASH).
RO-data: Read Only-data, indicates constants defined by the program, such as const type (FLASH).
RW-data: Read Write-data, indicates initialized global variables (SRAM)
ZI-data: Zero Init-data, indicates uninitialized global variables (SRAM)

With this you can know the size of the flash and sram you are currently using, so it is important to note that
the size is not the size of the .hex file, but the sum of the compiled Code and RO-data.

The above analysis will help you select external flash and external RAM.

STM32 Beginner's Notes 3 External Interrupts

For the third part of the study, I chose external interrupts, because I think that in addition to timing issues, interrupts are the most commonly used. Of course, there is a timer that I haven't learned yet, so I can only put it aside for later. Of course, I don't plan to spend too much time on GPIO, so I just read the

stm32 rcc clock

In STM32, when using any peripheral, the corresponding clock must be turned on, so I started with the STM32 clock. RCC Clock There are 5 clock sources in STM32: ①. HSI is a high-speed internal clock, RC oscillator, with a frequency of 8MHz. ②. HSE is a high-speed external clock, which can be connected to a quartz/c

How to make your own LPC17xx keil firmware library

Make your own LPC17xx firmware, mainly to solve the problem of LPC17xx utilization. Lpc makes its own keil firmware library I am used to the Keil environment and have just learned a little about STM32. I think the STM32 firmware library is very convenient to use. My seniors have talked too much and too much about LPC

A little discovery of stm32's window watchdog

Today I looked at the window watchdog of stm32 and suddenly found it very abnormal, so I did various experiments and came to the following conclusions. Since the conclusions are only experimental and there is no official conclusion, if someone has a theoretical basis, please let me know, thank you very much. 1. Once t
