Trouble with floating point conversions

Hi. If I create a C floating point number (ab) and set its value equal to a 32 bit integer (or a constant), the integer and the float are very different, at least as reported by the STVD debugger watch window. Normally, I'd expect to see a clean con...

STVD debugger hangs on a global variable increment

Hi. I'm trying to debug some code using the STVD IDE with the STLINK2 (SWIM). For some reason, it just stops at the line TSL_Globals.Tick_ms++;in the file tsl_time.c within TSL_tim_ProcessIT() and will go no further following a call to TSL_user_Init(...

STM8 community forum broken?

When I look at the STM8 community forum (https://community.st.com/s/group/0F90X000000AXt8SAG/stm8-mcus), I see no content.I tried with both Firefox 68.5.0esr and Chromium 79.0.3945.130.But I know there should be content: I posted something, and both ...

Hi, What is the status of port pins in STM8S003F3P6 when Reset is asserted? it is mentioned as HS(High sink) can i get the meaning if HS? Regards, Bhavishya Aj

Looking for sample external interrupt code for STM8S003F3P6

I'm new to STM8 microcontrollers and have purchased a few STM8S003F3P6 boards to learn how to interface a PS/2 keyboard and mouse. I have installed the ST Visual Develop IDE with STM8 Standard Peripheral Library and started tinkering with blinking a ...

i am currently working on a temperature project which many may well have heard of. the W1209 temperature controller. and i have found everything i need to implement this circuit into my existing project with other features. the code is open for anyon...

How to verify memory checksum in STM8S103F2 controller

Hi All,I want to verify memory checksum of my source code. I want to know, which register i can use to verify my memory checksum. Memory checksum i can see in "STVP" during programming, but that checksum i want to verify inside code. Advance thanks ...

One of our largest projects uses an STM8L151F3U6TR. We are trying to find out if any portion of this is manufactured in China or has any chance of having production delays due to delayed factory openings after Chinese New Years.

We are also using a LIS2DW12TR accelerometer. Same question as above.

Device that assigns programs to the empty processor ?

Hello friends,We use ST-Link when assigning programs to STM8 processors. ST-Link uses the SWIM leg when assigning programs to STM8 processors. We all know that.I want to make a device. Special bootloader. This device should be able to assign programs...
