When the power is off and the emulation port is used, everything is normal. When the power is on, it is all 2048 or 4095.I set the internal reference voltage to 2-2.5V.It's strange. I can't figure out...
Today, when debugging STM32F103RCT6, I found a problem. The previous library program did not run at all. When using the latest 3.10, I found that the program always stopped at while((RCC->CR & RCC_CR_...
The definition of strtoul is: unsigned long strtoul(const char *str, char **endptr, int requestedbase, int *ret) It can be seen that ADS1.2 will point the NULL pointer to address 0, but address 0 is w...
I have used OPEN AT to complete the GPRS activation part, but why can't I receive anything in the data stream? I can receive PPP packets by using ATD*99***1# in the hyperterminal. How can I use OPEN A...
In the MCS-51 microcontroller, a 12Mhz clock is used, and timer T0 uses mode 1 (16-bit counter). In the following program, what is the output frequency of p1.0? MOV TMOD,#01H SETB TR0 LOOP:MOV TH0,#0B...
