STM8 MCUs

We signed NDA, but it is already 2 months that we are waiting for response from ST. Meanwhile, our project is freezed. Can somebody and some level of ST help to move it forward? I read in forums that I can send the waveform I need and get from ST the desired DFU file - just to move forward the project until ST legal will decide to respond... Very disappointing support of ST on ST products on all levels, especially considering this is evaluation board, specifically designed to check, test and develop new products that eventually could use ST products.

Hello, I need to make this stm8s105c6 to control an 3.0 V PMDC motor using timers and microcontroller's clock. Also, I need to use pwm and this driver: EV - VNH7040AY. Timers:timer 1 -> accelerate to nominal powertimer 2 -> nominal powertimer 3 -> decelerate to 0I am totaly new and idk how to declare / write complicated sequences. I created an prototype with arduino and L298N. It is possible to translate it to STVD? Any suggestions? Thanks for attention!

Hi,I am using STM8S-discovery board. It started detecting as mass storage device as G drive. Will you please tell me what's happened to this board. I have reinstalled STVD IDE and ST-LINK driver too.

I am using stm8s discovery board with stm8s105c6 microcontroller. I am using demo code in stm8s_peripheral_library. I want discovery board should work as master. But I2C communication is not working,.Will you please help.Thanks in advance

Hello together,we use stm8af6246 for LIN communication with automatic header detection and mute mode (LIN Slave)In LIN stack description it is said that:“Mute Mode�? must be disabled for a LINSCI Slave node, when this is in Sleep State mode.Why should mute mode be disabled in Sleep State ?Best REgardsIgor

Our new ST-MC-SUITE provides easy access to all the resources you need for fast motor control application development with STM32 and STM8 microcontrollers.

Hi, i'm tring to use STM8L052C6T6 with Pads.but the PCB Decal of MCU seems weard.​It's covered with lines seem like the net.and the pin layout of the MCU doesn't match with the datasheet.​Is it ok to use in this status?​or do i have to do extra works for it.@ Attaching the screenshot of the pcb decal from Pads.​Thanks.

I added a new Cosmic license but still get the same result. The program will not execute any new code that I add. Suggestions?

Figure 152 shows identifier List Mode or Mask Mode is the first principal to choose Filter Match Index. While the above text reads the bit-length of filter is the first rule. So the text and the figure example illustration are confilct.Besides, on Page 392 in Table 65 FSC is written as "FCS".

Hi,How to enable the PWM to keep running when debugger stopped at brake point in the ST Visual Development. Tell me how to solve this problem.Regards,Nishanth M

Based on compile directives I can create variants of firmware. I would like the output name, TargetSName, to automatically match what was compiled. How is this done in this IDE?

I am compiling the Discovery project from STM8 UM0991 "Debugging Discovery", for a new STM8L Discovery kit.Processor target is STM8L152C6. Compiles fine in Debug mode.Project is unmodified except for: go to Project | Settings | C Compiler" and add a Preprocessor definition of "STM8L15X_MD".Rebuilt all files in Release mode, get the following errors:#error clnk Release\discover.lkf:1 no default placement for segment .dataeeprom#error clnk Release\discover.lkf:1 no default placement for segment .LPRUNGo back to Debug, project compiles fine.Did find the word "dataeeprom" in User/src/discover_functions.c, but don't understand the linker error solution.Cosmic linker FAQ says this is caused by not having the -a or -b flags....Already searched STM FAQ, Cosmic FAQ, and did web searches looking for a solution. Please help me get past this critical error.

Hello guysI am learning to use the peripheral ADC on uC called STM8L052C6 of the family STM8L , i have already read the chapter about ADC in the reference manual and in the datasheet. I read also the library about ADC, i mean the file .c and .h.There are 2 functions that for me are unclear :ADC_SamplingTimeConfigADC_SchmittTriggerConfigThere is someone who can explain to me this functions in a clear way with seample and functional examples?kind regards

Hi, I want to run STM8S003F with an external crystal.How do I use APIs in stm8_clk?Or in which material is it described?Regards, Gotoda

I am using my stlink (chinese clone) from last one year for STM8. It was working fine till last week. But when I upgraded its Firmware( to version- 2J37S7) from CUBEIDE then it started misfunctioning for STM8 . Only sometimes it is detected by ST visual programer. Also using visual programmer, program get uploaded but then it automatically get disconnected . It is working fine for stm32 but not for STM8. It all started after I upgraded its firmware 3 days back. Debugging in STVD stop working at all. I ordered new stlink but it too came with new firmware and has same problem. I downgraded the firmware to 2J16S4 but still it is not working.Following is the error in stvpError : Cannot communicate with the device !Check the SWIM cable connection and check all the needed pin connections on the SWIM connector.If the application code uses Swim Disable and Reset pin as Output or has disabled SWIM Clock
