Back to STVD debug error issue

Developed an app using the S105C6 MPU on the Discovery board, all went Very Well.Had boards made for the product - can't communicate - getting 40201 can't access configuration database. Others have had this, but NO answer has been posted ! What is th...

Cosmic cxstm8 absolute assembly examples?

I code in absolute assembler (30+ yrs). I have an app that ran fine under STVD, then something broke in the toolchain that even a fresh install didn't fix, so I'm learning CXSTM8. At build, I'm getting a segment overlap error. Pretty sure it's not kn...

STM8A wakeup from HALT by CAN Rx interrupt not working

I am using STM8AF5286 controller and CAN port for external communication. My application need to be in HALT mode to prevent battery consumption and wakeup only when any activity is detected on CAN port. The application works fine with wfi() function ...

STM8L Assembler in ST-Visual Develop IDE

Dear Forum Members,I am new in STM8 and I would like to familiar with this MCU series and use it.For starting, I would like to programming in assember. When I make a new project the IDE SW automatically generatesa basic code, but I do not understand ...

How to implement micros() function on stm8s003?

I need to decode ASK/OOK signal, for this aim I need to know the period in microseconds between several edges. I decided to use TIM1 for this purpose, here is my code // Set fCPU = 16MHz CLK_CKDIVR = 0; CLK_PCKENR1 = 0xFF; CLK_PCKENR2 ...

STM8S/A standard lib source code can't meet MISRA C 2004 rules

Hello, I use STM8AF as MCU, and the project is ASIL B level with functional safety. I downloader the STM8S/A standard driver, I apply MISRA C 2004 as rule to check the project. Oh, I forget to told the IDE, we use IAR for STM8. And we build the pro...

TIM1 one-pulse PWM on STM8S Discover board doesn't work as expected. First PWM output has wrong freq.

Please help these issues. Below issues 1 and 2 do not seem to affect each other. Goal: creating an one-pulse PWM output using TIM1 with output not changing state at the end of the pulse in idle. For example, in the scope capture (attached) I need to ...

Is there any special considerations for the SWIM connection on the STM8S005C6 compared to the STM8S003?

I have recreated the same circuit i used to program the STM8S003 into a STM8S005 i built 2 boards but the software its not being able to connect to the MCU. I leave the schematic:Is there anything Im missing could it be that the PCB traces in my boar...
