Today, we finally stabilized the two-way audio communication between our mobile phone and the single-chip microcomputer, and took the first step of success.
It can stably transmit a large data segment to each other, and both ends can fully identify the data.
Last week, the mobile phone sent data to the MCU through audio.
However, there is a problem that the mobile phone receives data from the microcontroller through mic.
The main problem is that the audio signal is
Fastmqv0.1.0 was released some time ago. This version has a fatal Memory leakage problem. When the concurrency is increased, the process will exit because of the variable in the thread. After two months of searching and troubleshooting, the change was finally completed in the previous week. However, this change has a large scope and does not involve the following:
1. Delete the thread pool and manage the thread using work thread;
2. The parameter notification method is not used for trigger
A normal system, in the process of continuous pressurization, should go through the following five stages:
Stage 1:As the number of concurrent users increases, the TPs of the system (the number of transactions processed per second) increases gradually until the maximum value is reached, and the response time of the transactions in this phase will not change much and will be very stable;
Stage 2:The number of concurrent users continues to incre
The program released yesterday did not work in another network environment. Check and find that the reason is that the HTML code returned by Sina Weibo is different in different environments. Unknown cause. However, the _ ieaction function is invalid. It takes three more hours to use another method. The method of driving the mouse should be more stable. The Code is as follows:
