STM8S ADC SCAN MODE Floating value observed on pin

I am using STM8S003F3. Currently my application requires sampling two ADC channels, which are interfaced with:1) Output of a resistor divider network which is routed directly to the microcontroller's ADC CH 32) Analog output of a sensor module PCB co...

Hi, I Am working on stm8l152. Which API is used for the Program halt function.? I have tried using halt() function. But it is not working.

STM8S007C8T6

Hi ST team, We bought 4500pcs STM8S007C8T6, COO is Malaysia, but MSL on the label is MSL 2, is it correct? Because we found official datasheet for this P/N is MSL 3. Could you please help explain why one P/N with two MSL? Thank you.

ADC input pin is driving a constant voltage of 2.9V

Using a resistor voltage divider (100k+47k) to break a range of 11V - 14V down to an ADC input range below 5V. For 11V i expect 3.5V, for 14V I expect it to be 4.5V.(see schematic)STM8s903 - ADC_IN_2 on PC4 (physical pin 14)IAR embedded workbench 3...

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

STM8S TIM2 Interrupt not working

Hi, I'm trying to Implement an interrupt every 60 seconds, however something is missing. The TIM2 itself is working but can't seem to generate any interrupt. Any idea on what am i missing? The following is the code I am using. thanks //Required Hea...

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...
