Although the IDE comes with a printf function that can be used for printing, it only supports a single serial port and requires microlib support in keil. Microlib is highly optimized, but the reentry
In the circuit design of modern scientific research institutions and the teaching of electronic systems in colleges and universities, integrated operational amplifiers are widely used as basic devices
The attached is a diagram I drew according to the schematic on TI's LAUNCHPAD. I made a board according to this, but the resistors of VCC and GND are only 400 ohms. This is definitely a problem. Becau
This is the schematic diagram I made by disassembling an MPPT charger before I graduated last year. The object I copied is a mature product on the market.
This circuit has been verified to be function
