Flash, reads the audio file from SPI Flash and output it through
SPEAKER.
BKP Read or write the backup register, check if it is correct or not,
and trigger the relevant LED at the same time.
CAN In experiment, CAN communication works in loopback mode,
transmit or receive a group data at the speed of 100Kb/s, and
when the speed reaches to 500Kb/s, it will transmit or receive
data using interrupt mode. This implements the CAN
interface’s self-check function.
CortexM3 The program demonstrates how to use CortexM3’s bit
management to execute read, write and the variable control of
reading SRAM.
CRC Generate CRC error-detecting code through CRC module.
DAC Implement DA conversion through DAC module
DEBUG The program simulates the condition when the fault parameter
is transmitted, the fault source will be printed in USART1 and
LCD, and it implements the debug simulation function.
DMA The program demonstrates how to transmit a group data with
DMA channel (from FLASH memory to RAM memory) and
the transmission state.
EXTI This program shows how to configure an interrupt line to get
an interrupt and trigger the interrupt processing program.
FLASH Implement the Erase, Read and Write operation on Flash’s
definite address, and checkout the written data, lastly read it to
FLASH and print it through USART1 and LCD.
GPIO This program has set a variety of ways to control GPIO, it also
simulates the transport control line which is used to control
JTAG by kernel, it will disconnect the JTAG when trigger an
external interrupt.
IWDG Using SYSTICK interrupt to reload IWDG counter (every time
350MS).
LCD Control LCD to show chars and colorful picture through
FSMC interface.
NandFlash Implement the read and write operation to NandFlash through
FSMC, and the result of operation is shown by LED, USART1
and LCD.
NorFlash Implement the read and write operation of external NorFlash
through FSMC, and the result of operation is shown by LED,
USART1 and LCD.
NVIC Nested Vector Interrupt Control, it links with three clocks, and
trigger the LED using interrupt.
PWR Control system into STOP mode, and system woke up by
EXTI interrupt.
RCC This program demonstrates how to configure the clocks of all
kinds of interface using chip clock’s manage function, and it
