STM8 MCUs

how does call(x) or call (Y) work? for example, i load Y with 9C52 , and then if the call is executed , how must i specify that addres in assembler how must it be labeled?or how must i specify that place in the program memory many thanks

Switch relay synchronously in 0 passage (50Hz)

i am trying to switch a relay via the stm8s001 processor synchronously in the 0 pass. how could I realize that.i have an imput signal of 50 Hz. I can also start the timer, but I don't know how to switch the relay on exactly in the 0 cycle.(i watch th...

How to generate PWM with offset / delay?

I need to generate two signals as shown below.I need to be able to adjust A and B independently. Is there some way to use TIMER1's OC1 and OC2? I can't figure out how to make an offset in the output compares - everything seems to start at the main co...

How to SWITCH HSI to LSE for STM8L152C6 discovery board?

When I switch HSI to LSE using IAR, there is always an error that "Failed to get execution status: SWIM error [30004]: Comm timeout"There is switch function:void HSI_TO_LSE(void){   if(CLK_SCSR!=0x08)    // if LSE is not selected as the system clock ...

How to generate a sinusoidal PWM with variable frequency?

I'm trying to generate a sinusoidal PWM on STM8, but it's for an equipmetn that the user will change the frequency of the output sine wave while the PWM is running. I was able to generate a sinusoidal pwm easily for a fixed frequency, using a table I...
