The following is a 485 circuit diagram and the register version code initialized in 485, hope to help everyone, just the code of the New Tang Cortex-M0, if not this chip can look at the steps, it should be no big problem. For example, the circuit diagram of rs85 communication: The following is the code: #def

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

The Cortex-A8 provides two interrupt modes: FIQ mode and IRQ mode.

there are so many possibilities, they inevitably have differences between, can find a good point out of it. So, here comes the second requirement, that is, how to effectively evaluate the results of the speculation, and then follow the assessment results to the best left. Specifically, we use the variance to evaluate it (in fact, you can evaluate it all, depending on your specific scenario), we follow the most in the middle. This basic logic is quite consistent with the basic pattern of cogniti

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 Cortex A8 is a processor based on the ARMV7 architecture, with a frequency of up to 1GHz. The processor based on CortexA8 has Samsung's s5pc100, S5pv210,ti's OMAP3530, and the A10 of all Chi. I have an idea that U-boot's 2-stage code is independent. The first phase of code is called hardware-related BL1, and the second-stage code is called hardware-independent BL2. There is just a piece of s5pc100 board on hand, it introduces the s5pc100 and verif

The ARM platform uses multiple levels of memory architecture to achieve speed and cost balance. For SoCs consisting of multicore CPUs, there is a set of caches inside each CPU, including: ICache, Dcache, and TLB. Multiple CPUs share a larger L2 cache. The L2 cache interacts with the DDR3 memory outside the CPU. Both ICache and Dcache know the instruction cache and the data cache. The TLB is actually a cache of page tables within the CPU, and is also divided into L1 and L2, which are integrated

I reported this error when I gave the stm32 program today. I searched the internet for a long time and found a reason and a solution. The online statement is as follows: Cause: Burned programsDisable the JTAG function.,JTAG interfaces are reused.. Solution 1: Find boot1 and boot0, lower boot1 and boot0 to 3.3 V, and download a program through the serial port. This program does not close JTAG, and then you can normally re-use JTAG, set both boot0 and boot1 to a lower value. Sol
