The life and death was not successful. I used micro SDHC according to the SD2.0 standard, but if I accept ACMDD41 in a loop, I will continue to receive 0x01. I don’t know what’s going on. I hope an ex...
In the process of embedded software development, generally speaking, the time spent on testing and coding is 3:1 (maybe more in fact). This ratio will continue to decrease as your programming and test...
After clicking a button, a thread is created and a parameter (a control, such as CComboBox) is passed in. When operating the control in the new thread, the system prompts that MFCCE300.DLL is wrong, t...
The use of a laminating machine is indispensable in the processing of multi-layer PCBs, and the uniformity of the pressure and temperature of the laminating machine has a considerable impact on the qu...
Serial port, also known as COM port, is an expansion interface that uses serial communication protocol. The serial port appeared around 1980, with a data transmission rate of 115kbps to 230kbps. The s...
There are five or six callback functions in the USB_Lib program, but I don't know what they do.For example , SOF_Callback, as the name suggests, is to generate a frame header, but I don't know if this...
