1. Now there is only one RS232 TTL interface USB port, which provides 3.3v 5v TXD RXD GND, a total of 5 pins. Can it be used to download programs to 430 in BSL mode? I saw on the Internet that RST and...
Since the battery voltage is 24V when fully charged, it will decrease as the battery is used, but the output is required to be 5V, and the output power is required to be relatively large. How to build...
There are many practical considerations when compensating an amplifier to get the fastest settling time (see Figure 1 in the text). Once an amplifier is selected, the only stability variable that can ...
How to use UART interrupt to send data? I used to assign value to UCA1TXBUF in the main program and send it, which was fine. But the interrupt does not work. Please give me some advice.
The routine gi...
