Cortex-M3 learning and debugging of stm32f10x UART In the process of learning the stm32f10x Development Board, the first learning routine is the UART Printing program. Due to the previous experience of single-chip microcomputer, UART programming is not unfamiliar, however, in order to lay a solid foundation for programming, the routine should be analyzed and introduced in detail, hoping to discuss with those who share common interests.1. stm32f10x UAR

Background: Raid is a Redundant Array composed of multiple low-cost disks. It appears as an independent large storage device in the operating system. Raid can give full play to the advantages of multiple hard disks, increase the speed of the hard disk, increase the capacity, and provide Fault Tolerance functions to ensure data security. In the case of any disk failure, you can continue to work, the disk will not be damaged. Raid can be divided into soft RAID and hard raid. Generally, medium and

The stm32-M3 has a system time base timer, which is a 24-bit descending counter. After the system time base timer is set and enabled, the counter is reduced by one every time the system goes through a clock cycle. When the counter is reduced to 0, the base timer automatically loads the initial value, continue to count down, and the internal COUNTFLAG flag will be set to trigger the interruption. The system time base timer function is simple, and only

This version of MySQL continues to improve the InnoDB Storage engine, mainly including: The InnoDB Storage engine is upgraded to version 1.1.1, which is also the latest development version. InnoDB uses a hash table to store redo logs during restoration. In 64-bit systems, the hash table size is 1/8 of the buffer pool size. To reduce memory usage, the size of the buffer pool for the hash table is adjusted to 1/64. If it is a 32-bit system, it is 1/128. In the slow query log, the Rows_examine

1. Read the cm3 authoritative guide, pointing out that the aircr value written to the reset is (0x5fa __set_FAULTMASK(1);NVIC_SystemReset(); System reset is recommended! 2. Change the Pc value so that the PC points to the Reset vector again. That is: void Reset(void){ void (*fp)(void); fp = (void (*)(void))(* (vu32 *)(0x8000004)); (*fp)(); } Recommended method: Improvement (loading MSP ): Typedef void (* pfunction) (void); // define the void resettest (void) {pfunction preset; uint

hardware resources, and 8051 of hardware resources are relatively simple.5. The flash and ram of arm are too large, and 8051 is too small to work. We take Keil official mcb950 Development Board and mill technology MYD-LPC1857 Development Board to make a comparison, the two are based on 8051 Single Chip Microcomputer and arm Cortex-M3 processor. + --------------
