STM8 CAN Filter

Hi,I am working with the STM8AF5286UDY and am trying to set up a CAN interface.For programming, I use the standard peripheral library. At the moment, my CAN interface works fine. The only thing, which does not work, is the filtering.I use extended ID...

Regarding S1 type s19 file

hi, every one I observed that in S1 type s19 file, the content is started with adress 8080, and in the end, there is 8000 adress, why they are given like that, there is any specific reason, can i make it in order by making change in settings in my I...

I am curious about the STM8L052C6T6 EEPROM operation.

I am using STM8L052C6T6.Current MCU knows that EEPROM is 256Bytes (0x1000 ~ 0x10FF).What happens if you use more than 0x10FF to put data in the reserved area address?If you do so, will the value of 0x1100 be put in 0x1000?And what happens if the MCU'...

Try to generate TIM1 overflow/underflow update event interrupt in center-aligned mode

Hi all,​I tried to configure STM8AF62Ax's TIM1 in center-aligned mode to generate 1kHz PWM output.​Also I'd like to generate a 2kHz interrupt by both overflow and underflow update event in TIM1.Now I can measure PWM patterns on scope, but the interru...

Hello all, How to detect that in a particular time period LIN message is transmitted or received in STM8Axx MCU? Regards, Shinde Umesh

how to force STM8S003 MCU to set UART1_RXNE_flag when receiving byte

standard IAR program. Transmit works normally ( without interrupts ).Receiving doesn't work not with flag polling, not with interrupt. I have seen in Internet similar questions, but no one answer with reasonable explanation or unconditionally working...

Loading value directly in the Index register "XL"

I am using STM8S103F2 controller in assembly language. I want to load directly value in "XL" index register in one instruction and i do not want to affect "XH" register. (Index "x" register is the combination of XH and XL). Other ways to load value i...

Breakpoints inside ISRs with STVD and STM8-SO8-DISCO

I'm using STM8-SO8-DISCO to program the STM8L001J3 uC which is attached to it. Before that I was developing my project using another kit and debugging was fine, but when I migrated the code to use it in this new kit (STM8-SO8-DISCO) I stopped being a...
