STM8 MCUs

Posted on April 16, 2014 at 17:52I need to a Debug an STM8L151 with ST Visual Develop, I have the cosmic compiler installed and activated.My Project builds, but wont start debuging.I get the warning/error ''Before running the application, you should first select a MCU for the project''Going to the project settings, it wont let me select any MCU, i've got an empty list. On another PC this list is populated.Have tried uninstalling and reinstall the compiler and ide multiple times.Using 32bit Windows 7

Posted on March 16, 2015 at 13:40 hello, here under my asm code for initializing UART2 of STM8s I use STVD IDE with stm8s discovery. when I put a break point at the end of the init, all the UART2 peripherals remains at 0x0000. I don't understand because I have init many others peripherals GPIO, Timer ... ;Uart variables M EQU 4 ; 8 ou 9 bit CR1 stop EQU 5 ; 1 stop bit CR3 bits EQU 4 ; 2 stop bit CR3 TC EQU 6 ; TC flag fin d'envoi TXE EQU 7 ; TXE flag write data CKEN EQU 3 ; clock mode in CR3 REN EQU 2 ; REN bit recept mode in CR2 TEN EQU 3 ; TEN bit transmit mode in CR2 ; init UART2 reset_uart_register mov UART2_CR1,#0 mov UART2_CR2,#0 mov UART2_CR3,#0 init_UART2 ; 2400 bauds = 000.000 / 2200 = 6666d = 1A0B hex bres UART2_CR1 , #M ; word lenth 8 bits bset UART2_CR3 , #stop ; 2 bits stops bset UART2_CR3 , #bits ; 2 bits stops mov UART2_BRR1 , #$A0 ; UART2 Baud Rate Register 1 mov UART2_BRR2 , #$1B ; UART2 Baud Rate Register 2 ld A , UART2_CR3 ''br

Posted on March 13, 2015 at 17:42 Hey, I want a very simple example: All elements on LCD should blink at startup(so in this very simple example: for everytime ;) So I want to use the BlinkConfig Function from the StdLibrary... My example code: 1. LCD_GLASS_Init(); 2. LCD_BlinkConfig(LCD_BlinkMode_AllSEG_AllCOM, LCD_BlinkFrequency_Div256); 3. while(1) 4. { 5. } I'm only using the StandardLibrary. When debugging, the values of the LCD_CR1 seems to be ok, but nothing happens on the LCD... How to let blink all elements on the discovery-LCD with the BlinkConfig command? #stm8

Posted on November 19, 2014 at 12:13Helloi�m new in STM8s105 microcontroller and cosmic c compiler.i wrote a small program:i set the clock with internall clock with prescaler 8:CLK_CKDIVR= 0b00011000;it means that my uc will operate at 2 MHz, right?i set the port D3 as output pin, push pull fast: PD_DDR=0B00001000; PD_CR1=0B00001000; PD_CR2=0B00001000; PD_ODR=0B00000000;in the main, i wrote this code:main(){ PD_ODR=0B00000000; PD_ODR=0B00001000; PD_ODR=0B00000000; PD_ODR=0B00001000; PD_ODR=0B00000000; PD_ODR=0B00001000; PD_ODR=0B00000000; PD_ODR=0B00001000; for (;;) {}}in my mind, if i set the port, it will in high level for 500ns, turn off for 500ms and so on... bu

Posted on March 09, 2015 at 19:16 Hi guys, I am trying to understand the ports of stm8s105c6.. I want to blink the led1 of the board on port PD0.. For what I understand I need to configure PD0 as Output, and after, drive current to the logic on front of portD0, configuring it as push pull low... I don't like to mess with STD Libraries for now, so, // Configure pins PD_DDR = 0x01;//output PD_CR1 = 0x01;//push-pull PD_CR2 &= 0xfe;//Speed of port configured to max 2MHz // Loop do { PD_ODR ^= 0x01; for(d = 0; d < 29000; d++) {//nothing to do, only burning cycles :S } } while(1); it seems that I have configured it to output push pull...but How to configure push pull low? By push Pull low, you mean PD_ODR = 0x01, and by high PD_ODR = 0x00 ?? thanks in advnce. regards tux

Posted on December 14, 2012 at 03:12I route VREFINT to an output pin and it reads correctly at 1.22V.If I vary my input voltage, the VREFINT raw count value drifts around between 1100 and 1300 counts using VDD at 3.22V.  The higher the voltage, the higher the count.I checked VDD going in and it is rock solid.  Same with VREFINT going out the PC6 (?) pin.I am in single conversion mode using PF0 (ADCIN24) as my input pin.Any help appreciated.  thanks, Jim  #adc

Posted on January 04, 2014 at 15:58Hello,I would like to know that if the SWIM output on the STM8L discovery board can be used to program/debug other STM8/STM32 Boards? instead of the STM8L chip on the same PCB.Thanks

Posted on March 03, 2015 at 11:58Hi,I have encountered with some issues with ADC readings.I’m using STM8S003F3 and reading 4 of 5 ADC channels (2, 3, 4, 6) and the readings are not as expected.For testing the ADC readings, I use STM8S003-Discovery and with a voltage divider for all channels sourced by the 3.3VDC i.e.:The voltage for channel 0 is 2.63VDC and I expect to read from ADC 815.The voltage for channel 1 is 1.98VDC and I expect to read from ADC 613.The voltage for channel 2 is 1.32VDC and I expect to read from ADC 410.The voltage for channel 3 is 0.66VDC and I expect to read from ADC 206. (The STM8S003-Discovery (STM8S003K3) has only 4 ADC channels.) Connection as describe in the attached Resistors.jpg.In the main loop, I use ADC reading as single channel single conversion mode, and read each time the next channel repeatedly from channel 0 to channel 3.

Posted on March 02, 2015 at 20:24Hello,My problem is using the STVD debugger.  The development platform is win7 64.  The tools are STVD 4.3.6, Raisonance Ride7 7.50.14.0185, RKit-STM8 2.54.14.0283.  The debugger starts normally, no errors, it appears to be ready, then I set a breakpoint in the source code, and get the following error message, Die: DW_TAG_padding(abbrev=0, offset=0) has children:FALSEError: Dwarf Error: Cannot find type of dieI have another development system, it is working properly, it is win8.1, the tools are STVD 4.3.2, Raisonance Ride7 7.42.12.0305, Rkit-STM8 2.48.12.0338. If I build the same project on the win8 platform and copy the .elf file to the win7 platform the debugger works properly and no longer gives me the above error.A binary file comparison of the two .elf files shows that the two are not the same.Also,

Posted on February 23, 2015 at 18:27I'm runningST library IEC60335 STM8AS v1.1.0 in a STM8S105C6.RAM March X periodic test is failing, I think there is an error in the library.Class B RAM (fromCLASS_B_START=0x10 to CLASS_B_END=0x7F) is checked from TIM4 interrupt by ''ClassBTestStatus STL_TranspMarchX(void)'' function.

Posted on February 17, 2015 at 14:04Hello im working with stm8s003f3 in that unable to use external interrupt pin..in datasheet its mention for 20 pin ic port b will have external interrupt capability.. I have made port B pin as input with interrupt then pogram the register for external interrupt but no result.. please help #stm8s-interrupts #external-interrupt

Posted on September 03, 2012 at 15:00Hi all. I'm developping an application on stm8S105S4, requiring among other peripherals, the use of 7 EXTI interrupts. -2 on port D -3 on port B -2 on port E. Scanning the forum, i ve read there is no ITpending flag to clear for these interrupts, nor status register allowing to see which pin has set the interrupts. Is there any way to see which pin has triggered ? I still may change pinning for 2nd run to split EXT ITs on the different ports, but anyway i still need 7 and there are only 5 ports which allow interrupts.... I see a walk around by using timers in input capture mode, but it's not really power efficient... Anyone has a clue ?

Posted on March 13, 2013 at 21:54I'm trying to compile the Demonstration sample from ST.com for my STM32F4, using Eclipse CDT and the GNU ARM Eclipse plugin. For more details and the Eclipse project, see Simply clone the project, and import the Eclipse project in the projects/demonstration folder, and compile, remember to install http://gnuarmeclipse.livius.net/blog/.I'm currently getting compilation errors:.../stm32f4-discovery/libraries/stm32_usb_otg_driver/src/usb_hcd.c:95:7: error: 'USB_OTG_CORE_HANDLE' has no member named 'host'Why am I getting this error?

Posted on February 04, 2015 at 10:36Hi folks We're using the 32k code-limited version of the Cosmic compiler: I've just downloaded the latest version 4.3.13 to ensure the bug exists in this, which it does... I suddenly had a report that my code had grown beyond the 32k limit, which was a surprise as I'd previously had about 1600 bytes free. After a bit of work, it looks as if the .bss section is being counted towards the limit, as it's about 1600 bytes long, and I can remove the error by making one array a couple of elements shorter. Here's the segment list from the .map file - if I try to grow .bss by 2 bytes the link fails, claiming my program is 32770 bytes:start 000080c0 end 00008d39 length  3193 segment .const start 00008e8f end 0000f9f8 length 27497 segment .text start 0000f9f8 end 0000fa00 length     8 segment .cksum start 00001000 e

Posted on January 06, 2015 at 15:55Hi guys, I am developing a tool for linux. grab it from : https://meocloud.pt/link/d1a42ac2-a022-4661-aee2-a1a2188c4c6a/LyPus/ Its for amd64 machines, it will create a folder on /tmp (where it will hold the session, and temporary stuff), and a folder on your home desktop, where you will deal with bin code for stm8 target.. do a ./lypus --help to see options :) for now only read is available, and only bin format by default...   I forgot to say that for now only bootloader is enable.. stlinkv1 is planned but not active, I need to redefine the backend of the application.. some examples: we will create a session, and at the same time, we will ask stm8s105c6

Posted on January 28, 2015 at 10:50Hi folks I've been debugging some code written by someone who susequently left the project, so I can't ask him... The code in question runs on an STM8L151G4, and concerns using it as an I²C slave, using interrupts. 99.999% of the time everything works as expected, but just occasionally the interrupt will trigger with the BTF flag set but neither TXE nor RXNE set. As far as I can tell from the reference manual this is not a valid combination, but I though maybe the collected wisdom here might have a better insight! Unfortunately this happens about every 5 hours of running, or longer, so it's really hard to capture exactly what has occurred. At the point where the flags are in this state DR has been neither read nor written, there shouldn't have been a start or stop condition and PE should still be set - even if any of these had happened, BTF should have been cleared along wi

Posted on September 12, 2012 at 11:57Dear all, I'm evaluating the possibility to perform a STM8 automatic module testing on the target using STVD. Unfortunatly, I have not found any information about the possibility to write scripts on STVD and so I suppose this feature is not available, isn't it? Is it possibile to access to the STVD source code to have the possibility to extend its functionality? On the STVD console window, I see it uses the gnu gdb front end for debugging: is it possible to have more info about how it works to debug an STM8 (i.e. customizations, commands)? I've enabled the logging of the console window and so I've seen what kind of commands are sent to the gdb, but some of them raise an error if I run gdb outside STVD: for example the command ''emulator-reset-port-mcu simstm8.cnf STM8AF6266'' is undefined. It could be very usefull to have a short example about how&nb
