The STM32 DAC module ( digital/Analog Conversion module ) is a 12-bit digital input, voltage-output DAC. The DAC can be configured in either 8-bit or 12-bit mode, or it can be used with a DMA controller. When the DAC is operating in 12-bit mode, the

Source: DC Motor Drive PWM frequency1, there is no unified standard, in fact, the frequency of PWM and your motor inductance and you need the speed response time has a great relationship. The general motor with 14K is enough. Of course, since the

With the rapid development of hardware and software, computer technology has been widely used in the field of automation control, in order to achieve real-time control, the control program must be able to accurately complete timing and timing

In fact, these two are different, last_insert_id () can return the ID of the bigint value. Instead, MYSQL_INSERT_ID returns an int. If you The ID of the unsigned int, or bigint. Then, it may be that the error is returned. Instead, use LAST_INSERT_ID
