can i use the _classb_checksum160 function on STM8AF5288 MCU for flash integrity check at startup ?

i had received this function from the ST Micro self test evaluation package for MCU STM8S207RB

Resolved! Hi experts! Do you know what is my issue? and how can I solve it? I'm using the ST-link v2 with the STM8 part as you can see below.

Hi support team, I'm working with the stm8a-discovery evaluation board and ST recommends use cosmic c to used with ST Visual Develop software.. Could you please bring me the software please? Best regards, Tania

Resolved! Is the new STLINK-V3 compatible with STM8?

ST Visual Develop

Hello, everyone,I have a problem with ST Visual Develop, version 4.3.12 (See attachment 1)If I launch ST Visual Develop as administrator, I am not allowed to enter debug mode, but I get the message: "** Connection error (usb://usb): gdi-error [40201]...

Resolved! Hi,I am working on STM8s0003f3.I need to read analog voltage from ADC_Channel_5 I have stuck at how to initialise channel cmd for the same as I dont find any ADC_Read examples.Can someone help me sort it out please

STM8L151K6:COMP2...Does closing WINDWE analog switch (for Window mode) disconnect COMP1 non-inverting input from AS14 in the analog switch matrix?

Using the Cosmic IDE, I have the non-inverting input of COMP1 driven from PA4 by closing RI_AnalogSwitch_14 and RI_AnalogSwitch_0 and enabling RI_IOSwitch_3. I have COMP1 configured for COMP_Edge_Rising and the COMP1 interrupt is enabled. I see inter...

Able to control STM8S nucleo board, but same code to chipset on my own board does nothing. How can I debug?

I use STVD with the cosmic compiler, SPL library and STVD to flash. I am able to control the STM8S208RB Nucelo board with this setup, and verify the board is functioning correctly.I then lay out a PCB with a STM8S003F in a TSSOP-20 package. The layou...

What is the right SW to program STM8 microcontroller with STLINK-V3SET programmer? I need to use SWIM interface. I have tried to use STM32cubeprogrammer, but there is no option for SWIM and it doesn't work.

STM8S103 using GPIOB4 as normal GPIO

Hi all.I tried to use GPIOB4 as output but failed.But it works as I2C SCL so I guess the chip ok.I cant find alternate function for it.Someone please help me.
