kandi X-RAY | stm8 Summary

stm8 is a C library typically used in Internet of Things (IoT), Arduino applications. stm8 has no vulnerabilities and it has low support. However stm8 has 1101 bugs. You can download it from GitHub.

For compatibility with other STM8X (e.g. L) series of MCU's make sure the registers in the "include/stm8s.h" are compatible with your own MCU. Just make a copy of this file and apply changes according to the datasheet of the chip you have at hand. For tutorial on programming these examples on your MCU, please check the guide to flashing stm8 on linux.

How to Debug in STMCubeIDE?

Asked 2022-Feb-15 at 18:57

I am new to STM32. I have recently installed STM32CUBEIDE. I have written basic code . connected ST-Link v2 (STM8 & STM32) to my laptop and pressed F11 (to debug). I get the following error

I hate the same problem a while a go. In my chase the debugger it self (st/linkv2) was broken and I tried to upload it with a other dongle and it worked fine. So it could be just be a broken dongle.

QUESTION

STM8 as SPI slave can't send back data

Asked 2021-Sep-27 at 15:38

I have build a prototype board with a STM8L, and I want it to be used and configured as a SPI slave. I am testing it with a raspberry pi as master.

I use the lib provided by ST called "STM8 Standard Peripherals Library" for this, but the documentation is very poor and doesn't expain how to do this...

I can send data from the Raspberry Pi with no issue and receive it on the STM8 but I can't send back any data to the raspberry from the STM8 on MISO.

Is anybody known how I can send back some data to the Raspberry Pi master? Where is my mistake?

Here is the main code:

SPI requires the master to provide the clock. If you want the slave to send something - your master has to send some dummuy data to generate the clock for the slave.

How to Convert the last digit of a number to a char and display it on LCD?

Asked 2021-Aug-21 at 07:27

I recently got a STM8 MCU and it has the built in function LCD_GLASS_DisplayString("STRING")

The problem with that function is, as you can see below, that I cannot directly display an integer on it:

ANSWER

Answered 2021-Aug-20 at 11:17

You're not far off with "0" + integer%10 - but you need to treat it as a character - '0' + integer%10 - and you need to pass LCD_GLASS_WriteChar a pointer to this character.

One way to do this is:

QUESTION

SDCC generates unnecessary division by zero

Asked 2021-May-06 at 00:31

I'm using SDCC to compile for a STM8 microcontroller. Compiling the following file results in a seemingly unnecessary div instruction - which is very slow on the STM8.

...

ANSWER

Answered 2021-May-05 at 13:42

Looks like that's a bug somewhere in the compiler because if b = c >> 0 is changed to b = c << 0, b = c + 0, b = a[0]... then no such thing happens. The behavior is observed on both optimized and unoptimized code. But if you optimize for size (--opt-code-size) then only the div is there, the clr instruction isn't emitted. You might want to report that to the developers

STM8: local declared pointer on global variable

Asked 2020-Oct-27 at 14:18

on my STM8 Disco Board with Cosmic Compiler I tried follwoing code and expected 'ptr_a' and 'ptr_aLocal' to be the same:

ANSWER

Answered 2020-Oct-27 at 14:12

Various older versions of misc embedded compilers tended to optimize code somewhat even when optimizations were supposedly disabled. Particularly Cosmic and Codewarrior had such quirks in older versions. Since the local variable isn't used, it is optimized away.

You can see this for yourself by viewing the generated assembler - any half-decent debugger will support assembly step debugging. If there is no stack push or index register store instruction there, then it was optimized away.

You can force the variable to get used with volatile int *ptr_aLocal.

Unrelated to your question, you should use uint8_t as far as possible nad not int, when programming 8 bit microcontrollers.

c# API or SDK for st-link v2 or SEGGER J-Link flash downloader

Asked 2020-Jan-17 at 14:35

I am wondering if anyone have worked with a custom .net C# GUI that are able to do flash download for an STM microcontroller via ST-Link or SEGGER? I know that segger have their SDK, but it is not free. Are there any opensource API that we can use instead?

Any help will be appreciated, thanks!

If you want to program uCs from your C application just use openOCD (free) and send commands to it. Works with almost every popular debug probe.
