To summarize a few points, I hope friends can add to it: 1. Look at the pins: 14 pins are 1/4, 16 pins are 1/3; 2. Visual inspection: one-third is much larger than one-quarter CCD; 3. Effect: using th...
I am working on a handheld project recently. I need to use the zigbee module on the handheld. When I turn on the zigbee module, the handheld will reset and shut down. I tested that when the zigbee mod...
In the F4 CUBE library provided by STM32, the following code is provided in stm32f4XX_hal_def.h: [code]#if (USE_RTOS == 1) /* Reserved for future use */ #error “USE_RTOS should be 0 in the current HAL...
The signal collected by this system is very weak, 5~100uV, and the designed circuit needs to amplify it 40000 times. Since the larger the AD620 amplification factor, the greater the error, this circui...
I am using 16F690 to make a PWM signal project, but the PWM signal is not output. The program is as follows #include#use delay(clock = 12000000) #fuses HS,NOWDT,NOPROTECT,PUT,NOBROWNOUT,MCLR #use fixe...
