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...
Posted on September 03, 2013 at 12:25Yesterday I had a look at the pointer indirect long addressing mode. It seems this one is useful only when register X is in use for other purposes: Loading into a: ldw x, $5000 ld a, (x) vs ld a, (($5000) Both ha...
Posted on July 09, 2013 at 09:22Hello, I'm trying to get a first program on a bunch of new STM8S207K6 but the device does not answer. It seems like the reset pin is pulled low by the controller and the programming tool keeps telling me ''Error: Cann...
Posted on August 30, 2013 at 22:12I use the Cosmic 4.3.9 compiler(32K free) with the built in functions _checksum16() or _checksum16x(). When my program memory cross over the 0x10000, these functions become unreliable. Before crossing 0x10000, eve...
Posted on August 30, 2013 at 12:01Hello, i have already installed the development environment ST Visual Develop rel. 4.3.1 already used for the processor STM8L151C4 with the c compiler Cosmic 4.3.9 Now i have to use the processor STM8L052C6 but in ...
