STM8 interrupt vector table fixed in 0x8000 address, cannot be modified, so boot zone can not be interrupted, otherwise will and app area interruption fight, However, once the app area is interrupted, it jumps to the 0x8000 address and jumps to the boot area, so you need to jump back to the app area with a jump command.__rootConst LongReintvec[]@". Intvec"={ 0x82008080,0x8200b004,0x8200b008,0x8200b00c,//when the application address is not a 0xb000, c

Beginner STM8, first follow the online tutorial set up a IAR project, and then download an official firmware library, made a case template, the function is super simple, is a LED light flashing, main function on this point content: void main (void) {/ * Initialize I/Os in Output Mode * /Gpio_init (Led_gpio_port, (gpio_pin_typedef) Led_gpio _pins, gpio_mode_out_pp_low_fast); while (1) {/ * Toggles LEDs */ Gpio_writereverse (Led_gpio_

Learning STM8 There are only 6 registers in the STM8 CPU, i.e. A, X, Y, SP, PC, CC. Complete the 2 8-bit unsigned number additions to the memory, and the results are also saved to memory. unsigned char a,b,c; c = a + B; The STM8 is compiled as follows: LD a,$1000 ADD a,$1001 LD $1002,a This assumes that the A,B,C 3 variables are stored in memory,

STM8 's I²c interface 1, I²c mode selection The interface has 4 modes: from the device transmission mode, from the device receiving mode, the main device sending mode, the main device receiving mode 。 By default, the I²c module works in slave mode. The interface automatically switches from slave mode to main mode after the starting condition is generated When the quorum fails or when a stop signal is sent, the switch from mode to slave mod

Source:STM8 without manual reset enter the self-bootloader method (serial download)STM8 without manual reset enter the self-bootloader method (serial download)Unless the STM8 film is empty, if the reset is running with bootloader, and to download the program through the serial port, you must click on the host computer within 1s, or run the user program. This step is troublesome, so I want to dispense with i

A long time ago played a few days STM8, today there is a project, leadership in order to save money, let me use this chip development, Cha, in the heart immediately feel there are 10,000 grass mud horse in the Pentium, so degrees ah degrees, pieces find some information, deliberately recorded down, in case later use and forget.The specific installation steps are as follows:① installation Sttoolset_pack33.exe② installation Cxstm8_32k.exeInstall this so

The clock

After the STM8 system is reset, all peripheral clocks are in the open state. The user can clear the CLK_PCKENR1 or The Pcken bit in the CLK_PCKENR2 to turn off the corresponding peripheral is the clock. Clock Divider Register (CLK_CKDIVR) If a PIN has only the output capacity of the level, it is said that the PIN is an output pin or drive pin; If a PIN has the input capability of the level, the pin is said to be an input pin. Pins with both in
