Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
Posted on October 10, 2013 at 08:52Hello, I have a simple question: uint32_t temp; temp |= ((uint32_t)1 << 16); without retyping it does not work (although if I add the expression to Watch, it shows expected 1 on 16th bit of temp). Why? I use Cosmi...
Posted on September 11, 2013 at 14:17Hello,I am currently working on STM8L15C6. For my application I need to read the value stored at location VREFINT_FACTORY_CONV. The value at this memory location is 0xFF. We were assuming the value to be somewher...

Posted on September 26, 2013 at 05:36Hi. Trying to find out what, if anything, the STM8 compiler does with the @stack function qualifier. The STM8 LIN Driver uses @stack quite a lot, however it is not documented in the Cosmic STM8 User Manual. Tha...
Posted on September 19, 2013 at 11:21Hi, today I have a very special question: I read in the programming manual, that the instructions DIV an DIVW are interruptible. What exactly happens, when an interrupt occurs while calculating is active - with ...
Posted on May 16, 2013 at 08:18Hi, I have a problem with USART half duplex. The output from my STM8L device is too strange. The first half (about 10 bytes) is from host. My device can receive this well. After that, the host is wait to receive the...
Posted on September 02, 2013 at 20:10I know of sdcc, Cosmic C, Raisonance. Apparently, there also is ST8CC, but it seems to lack documentation, and seems to only support some restricted subset of C. Are there any other C compilers targeting the STM8...
Posted on August 06, 2013 at 15:27Hello! I'm can't programming option byte in the stm8s105c6t6 into my board stm8s-discovery. This code: mov FLASH_DUKR,♯$56; mov FLASH_DUKR,♯$AE; ld A,♯%00001100; IWDG_HW and LSI_ EN set ldw X,♯$4805 ld (X),A i...
Posted on September 02, 2013 at 20:05So far I have used an STM8L-discovery, but the 1K of RAM is not enough any more. I need 6K. Otherwise I just want an LED or two, some GPIO and a serial port. Any recommendation? Philipp P.S.: There is this STM8/1...
Posted on February 12, 2013 at 23:04I'm learning how to use ST micros (after years of using PICs) and I am struggling to integrate the GPIO files. I added the stm8s_gpio.c to my project and this fixed the UNRESOLVED EXTERNAL errors however now I get...
