UART issue for reading 2 or more bytes length

I am having an issue with the UART1 communication between two devices (Computer and a STM8S208 board).I implemented software in the computer that writes two bytes length of data to the STM8• the first byte that acts as an identifier;•the second byte ...

General software design tips

Hello guys. I have a general question actually I need suggestions. So I did not want to open a topic for it. I need to make a presentation about a box which will be in some armored vehicle. This box will be like the brain of the vehicle and will cont...

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...
