There is no model identification information inside the 24 series memory. I have different models of 24 IC installed on my board. I want to write a program to determine the address, storage capacity a...
I made a clock program using dot matrix, used timer0 to control dot matrix refresh, used timer2 to use asynchronous clock 32768 for timing. Now I have a problem.I made a rolling subtitle and hope to d...
[size=4] The entire software library uses a non-blocking method, so a large number of status returns are returned through callback functions rather than waiting for the function to return a value. The...
I found a very frustrating problem. I downloaded the program into it and powered it on directly, but found that the crystal oscillator did not start. I powered it on several times. It still did not st...
At present, the development of wireless power supply technology for electric vehicles (EVs) is becoming more and more active. In 2012, Volvo of Sweden established Volvo Technology Japan in Tokyo as...[Details]
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
Automotive applications are particularly sensitive to EMI events, which are unavoidable in a noisy electrical environment consisting of a central battery, bundled wiring harnesses, various inductiv...[Details]
