SQRT in STM8 STVD

How to calculate the square root in the STVD?Is it necessary to use a library? Where can I get this library?

I am using STEVAL-ILD004V2 source code for dimmer. I can compile using my ST Develop using STM8 cosmic compiler when no change. But, when I change MCU to STM8S103F3P. I will have this compile problem below. Regards, Walter

STM8 STUDIO doesn't work

Hello to everyone, when I get started recording session, it runs for few seconds then it stops and I need to restart. Someone has sort this issue out? ThanksFabio (english and italian)

STM8L051

Hi, I am not sleeping this microcontroller. I search example code but I couldnt find it please help me. Thanks.

Is it possible with the STM8L151G4U6 to count an external clock of about 10MHz ? I would like to count during about 3ms and update the value each 100ms. regards Benjamin Menard

I am trying to interface conductive fabric as a touch sensor instead of electron on stm8s-discovery board. I am facing problem in that, is when my finger above the touch sensor it also detects finger and changes accordingly .

please help me and tell what i want to do.....

Error : SWIM prog error[42007] buffer program error

When we debug with ST-link/V3set on STVD, we found this issue swim prog error[42007] buffer program error.but we didn't found this issue with ST-link/V2.How does solve this issue when we used the ST-link/V3set ?

With the STM8s105c6 and the STM8af5288tay, both which I use. what is the correct way to initialize multiple i2c devices on the same SDA/SCL port. i.e. I wish to have a RTC, i2c LCD as well as an EEPROM on the same i2c port.

How for example do I initialize all 3 devices, where addressing and necessary parameters are concerned.  Any sample code or advice in this regard would be very welcome. (RTC : either PCF8563 or DS1307; I2C LCD with PCF8574 expander and 24c32 or 24c64...
