STM8 MCUs

I'm trying to add multiple interrupts on the same port (portD) on my stm8s003f3. I'm not able to attach the second interrupt to the ext interrupt handler function. Some info might help.

STM8L151F3U6TR comparator 1 register not writeable.

HelloI'm using an STM8L151F3U6TR. A lot of things are working fine.But the comparator 1 seems not to work.It seems not possible to write its registers.If I execute the following code with debugger, then "dummy" changes from 0xFF to 0x00.I would have ...

Hello, i am using mcp6s26 gain amplifier ic for temperature scanner .so i dnt know idea about how to use or working with spi can anyone knows about this?

STM8S ADC Scan Mode not updating

I am able to read my two ADC inputs individually when I implement the code shown in this example: http://embedded-lab.com/blog/starting-stm8-microcontrollers/13/However, the ADC values in the buffers do not seem to be getting updated when I try to ge...

STM8S003F3U outputs behaving weirdly during BOR.

I have been working on a battery powered application and am experiencing some strange behavior when the batteries are dying. The LED array is being driven by a PWM signal on PD4 through a FET. When the +4V power line goes down to 2.6xx V, all of th...

Behavior of X/Y indexed addressing modes on the STM8

I'm trying to write an emulator for the STM8 MCU family. Most of the opcodes are implemented, but it's doing things I don't expect, and I think the problem lies in some of my addressing mode implementations. The following questions seem obvious, but ...

hello sir can some one tell me about the way to see the cpu frequency on the cco output.

helloits not that clear what the manual and data sheets say about the "configururable clock otput register.normaly i set port d as output with portd cr1 alsso setthen i set the ccoen bit in the clk_ccor registerthen i write 15 in clk_ccor register...

UART Even Parity gives parity error

Hi,I'm using STM8S for UART half duplex communication (single wire). I'm using the standard library to set the UART up in 9600 baud rate, 8 data bit, even parity and 1 stop bit. I recieve data using interrupts. On the third byte, I get a parity error...

Hi, I have the STEVAL-LLL002M1 evaluation board and I was wondering how I can program the LED drivers to show custom LED patterns. I have installed the STSW-LLL002 GUI but I do not know how to save the custom patterns on the device. Thanks

STM8CubeMx and IDE

I just started to working on STM8L162. I worked on STM32 SO, I searched the tool like STM32cube MX for STM8 and I got it. STM8CubeMX does not support the code generation yet. So , is there any other tool for STM8? From where I can download the driver...
