IAR usage notes

IAR usage notes (1) At a.m. on October 10, August 8, the topic of the online discussion on China power grid was "the development and debugging of NXP Semiconductors Based on the lpc2000 microcontroller ". I tried to use IAR in the lab at night, but I was still unfamiliar with it. So I downloaded the PPT for this online discussion to my machine and checked it again. However, I am tired of reading the PPT. I 'd better remember the key points. (1) Projec

Recommendations on ARM chip selection

Currently, arm is common in the Chinese market, including NXP (Philips), Samsung, Atmel, Ti, and Adi. According to user requirements and application fields, you can select from the following aspects: 1. Speed (for common applications): The main clock speed of ARM7 is 20 ~ 133 m, 100 ~ 233 m, arm10 up to 700 m, if the speed requirement is higher, you can also use multi-core arm, such as minspeed ARM chips. 2. Memory (conventional applications): Gener
