1. Write an interrupt service routine
Write an ISR function c_intXX in the .c source file for interrupt processing, such as:
interrupt void c_intXX (void)
{…;
}
Note: For hardware interrupts, XX = 00~...
The setting is: AT+CNMI=2,1 When the MCU receives the message, sometimes there is a new message prompt, and sometimes there is no new message prompt (no prompt is the majority of the time). Why is thi...
I use FPGA to configure ADV7181B through I2C. Through the logic analyzer, I can see that the device address, slave address, and data output by the FPGA are all correct, but ADV7181 does not respond. H...
