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...
My wince system has been installed with compact framework 2.0. During this period, the dotnet program was running normally (the program often reads and writes files). After running for about a month, ...
