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
Ti official website download stellarisware package, decompress by default path, in c: \ stellarisware has multiple folders, where C: \ stellarisware \ board \ rdk-s2e folder is the main character: source code for serial port to Ethernet. It uses lwip1.3.2 as the TCP/IP protocol stack.
TI's serial port to Ethernet module can quickly convert serial transmission to Ethernet transmission. The module includes a microcontroller based on ARM cortex m3, a pai
byte in length, many other commands are 2 or 3 bytes in length. This is usually the case for a 16-bit architecture, where some commands may occupy 6 bytes or more memory.ARM Cortex-M3 and Cortex-M0 processor leverages ARM Thumb-2 technology that provides excellent code density. With Thumb-2 technology, the Cortex-M processor can support the fundamental foundation of 16-bit Thumb commands that have been extended to include more powerful 32-bit command

I am using NXP cortex-m3 chip LPC1768 as the master chip, after repeated research and experiments, modify startup. the size of stack_size and heap_size in s Code does not help. However, there is a strange phenomenon, that is, the single-step debugging can only be executed once, and the results obtained this time are correct, then there will be a hardware error immediately and an endless loop of hardware errors will be entered into the assembly languag
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.
