I don't know why, the SD card often reports the following error mmcblk0: timed out sending r/w cmd command, card status 0x400e00 Then the system crashed [code] INFO: task kworker/u4:2:58 blocked for m
The method is to use IBasicBitmapOps to rotate. The code is roughly as follows: IImagingFactory* pImgFactory = NULL; IImage* pImage = NULL; IBitmapImage* pbmpImg = NULL; //bmp image IBitmapImage* pNew
For example, the output impedance of 8065, judging from the parameters given in the datasheet, seems difficult to match if the impedance needs to be matched to 50 ohms later. Can a transistor emitter
1. The LM3S3748 chip we used could not generate PWM signals directly. We had no choice but to use PWM interrupt to simulate the PWM signal. Although this problem can be solved temporarily, we still do
