How to generate a sinusoidal PWM with variable frequency?

I'm trying to generate a sinusoidal PWM on STM8, but it's for an equipmetn that the user will change the frequency of the output sine wave while the PWM is running. I was able to generate a sinusoidal pwm easily for a fixed frequency, using a table I...

Question about "15 kW, three-phase Vienna rectifier with low cost mixed-signal control for power factor correction"

https://www.st.com/en/evaluation-tools/stdes-viennarect.htmlI have some questions about the PDF "stdes-vienna rect" that can be obtained from "Download data brief" in.1) Why is the CCO_clk on page 4 connected to DIGIN [1] and DIGIN [2]? Does it make ...

I am using stm8l051f3 & I want to integrate it with IR sensor VL5310x. Can I have any open source code ?

LIN STM8 Package v.5.1 Demo with STM8A-Discovery - Slave pre configuration with sd_set_configuration

Here's the issue. I have built a LIN bus with a slave node and a master node using tow STM8AF/AL-Discovery boards. After flashing the boards with the demo of the STM8 LIN driver 5.1 as slave node and master node I can control either the LED or the b...

Triangle signal at the CCO Output (Port C4) / STM8S001JM3

Hi,I generate 2 mhz from the PORT / PIN C4 (CCO).The problem is that instead of a square signal, I get a triangle signal.What could be the reason????On PORT / PIN A3 i can generate a square signal, but not on C4I Use the STM8-SO8-DISCO Board in which...

STM8S clock and serial port initialization problems

I am using an IAR compilation environment, the microcontroller is STM8S105C4T6, but in the clock initialization, CLK__CKDIVR=0x00; the CLK__CKDIVR in this sentence keeps prompting that this function cannot be found.And it is the same when initializin...

Error - f_FLASH_ReadByte not defined when linking

I have just come back to STVD after a long while (and various changes of machine) and have reinstalled STVD and COSMIC. I can now compile my existing code but when trying to link it during the build process I get a page of errors like;#error clnk Rel...

Hi all, My question is about the stm8 series. I am currently working with stm8s001jm3 and am trying to generate 2 MHz from a pin. The problem is that I can only generate a maximum of 380 kHz, although I have set everything correctly.

Im using the COSMIC Toolchain with the standard library.Here is the setting:##########################################################void clock_init(void){ CLK_DeInit();              CLK_HSECmd(DISABLE); CLK_LSICmd(DISABLE); CLK_HSICmd(ENABLE); whi...
