STM8 MCUs

Posted on March 18, 2011 at 16:24I have just purchased the STM8L-DISCOVERY, I have problems getting the device communication functioning on my primary PC. I have installed all the same apps... on a secondary PC, on this PC all is OK.On my primary PC I get: ** Connection error (usb://usb): swim error [30004]: comm timeoutfrom the ST Visual Develop.I have tried several solutions, without luck, and I suspect a OS issue.The primary PC, is W7-64 bit, the secondary PC is W7-32bit.ThanksCasper Dietrich #stm8l-discovery-64bit

Posted on July 01, 2010 at 01:39Hello all, The analog to digital example provided, ADC, uses 1 analog channel (channel 9) only.  I am working on an application and need to convert 2 voltage channels. 1) is there a way to set up the A/D to cause an interrupt when 2 channels have been converted.  If yes, could someone provide the setup C sequence and the interrupt service routine C sequency (ADC example has the setup in main.c and interrupt service routine in stm8s_it.c).  I have found a SCAN bit in ADC_CR2 (Ref. Manual), presumably channel can be scanned; no info on which/the order of the scanned analog channels; how do I select say, ch 8 and ch 9 for scanning? 2) if the above cannot be done automatically, do I have to select the next channel in the interrupt service routine of the timer, and read the A/D in its interrupt handler; if you could provide the C sequence, that wou

Posted on March 15, 2011 at 04:47Hi We want to perform software reset through software for the STM8L151c6T6 micro-controller. Can you please tell us the instruction or C function which can perform it? With regards Gagan Gupta #stm8l151c6t6

Posted on February 12, 2011 at 04:39I can change the sys clock source from  HSI to LSI success in the debug mode with ST_LINK in  the   IDE   Iar for stm8. But  it can't success  when abort the  debug mode.  i need a help,someone can  help me. This is my code:                 CLK_CKDIVR_CKM = 0;                 //????????                 CLK_ICKCR_LSION = 1;                //??LSI                 while(CLK_ICKCR_LSIRDY);         &nbs

Posted on March 30, 2011 at 09:42HiI need to upgrade the flash image in the STM8S via a primary ST microprocessor. I am going to use the SWIM protocol to do this upgrade.Is the any sample SWIM software which i may use to implement my driver or port to my platform?Thanks

Posted on March 29, 2011 at 19:21There is actually 20 ''STM8S-Discovery'' in our classroom lab that works well with STVD debugger.  All message in this forum about debugging issue with ''STM8L Discovery'' using STVD suggest to try other computer as a possible solution so to make STVD communicate with the ST bords.. This is not real solution because we won't change all these new computers just to make ''8L'' version usable. There must be someting wrong with STVD since DTVP do communicate normally with the ''STM8L'' boards on all computers in the same classroom lab. So there is now 20 ''STM8L'' boards waiting on the shelf for a solution Regards N.R. #debugging

Posted on March 29, 2011 at 15:42HiI am designing my code using the STM8S Discovery.When using the Cosmic compiler i get the following files generated after compiling(no debug).stvd_project_dtd416.elf       (29KB)stvd_project_dtd416.lkf       (3KB)stvd_project_dtd416.s19     (27KB)stvd_project_dtd416.sm8    (31KB)Which of the above images is actually written to flash. I am implementing a ICP using SWIM which will write the actual image directly to flash program memory so i need to know which image to write.Need help urgently.Thanks 

Posted on March 16, 2011 at 15:51HiIm using the STM8S discovery kit together with the standard firmware libraries. I need to use string functions such as strtok(). How do i get these functions to work in this environment. Including string.h wont work. Do i need to implement the string functions or is there an easier way?

Posted on March 15, 2011 at 07:03I am trying out the new STM8S TSL v2.3.1 and it failed to compile the library source files.It fail on all the TSL source files with error message as below (same for other files). What can I do to resolve the issue?Using STVD v4.2 with Raisonance toolseet v2.32.10.0307 and STM8S Discovery Board.P/S: I've attached a sample project to illustrate the problem.Error message: ================================================= Compiling ..\libraries\stm8_touchsensing_driver\src\stm8_tsl_api.c... rcstm8 ..\libraries\stm8_touchsensing_driver\src\stm8_tsl_api.c OBJECT(Debug\stm8_tsl_api.o) PIN(''C:\Program Files\Raisonance\Ride\inc\ST7'') PIN(''C:\Program Files\Raisonance\Ride\inc'')  WRV(0) STM8(SMALL) DEBUG DGC(page0) AUTO  OT(0) PR(Debug\stm8_tsl_api.lst) CD CO SB LAOB PIN(..\libraries\stm8s_stdperiph_driver\inc) PIN(..\libraries\stm8_touchsensing_driver\inc) PI

Posted on March 10, 2011 at 08:58Hello together, yesterday I separated the ST-LINK module from the STM8S105C6T6 module of my STM8s discovery. Afterwards I measured the power consumption and unfortunately it was much higher than expected. At a voltage level of 5V it consume 66mA and in active halt mode still 40mA. Has anybody of you made some different experience with other consumption values? Thanks in advance #stm8s-discovery-power-consumption

Posted on March 06, 2010 at 02:36What a pity. If it would support Linux, I could actually use it, now that I have mine - but it seems like Arduino is the way to go. Another piece of good hardware wasted due to crappy software support...

Posted on March 02, 2011 at 11:48 I am using the following code for master and slave handling. When I send data from master to slave without using the interrupt routine below(by disabling intterupts) it works fine. BUT when I use interrupt routine it never comes out of it, please help  me correcting it #stm8s-discovery

Posted on February 19, 2011 at 15:40  Can't get working T4 overflow interrupt on STM8S103F3P6 (on STM8S-Diskovery with STM8S105 the same code works well): TIM4_CR1 = 1; TIM4_PSCR = 7; TIM4_IER = 1; Need minimal code to enable Timer4 overflow interrupt (Cosmic-C), thanks In debugger TIM4_IER == 0.

Posted on June 15, 2010 at 17:25Dear friends, this improved version of the ''int2str'' function will solve a bug present in the original version provided with the hyperterminal example though it is used nowhere in that example. I'm working on an application to perform analog conversion and then send the value to the hyperterminal like a simple datalogger. When converting the int data from the adc to a string the original routine doesn't manage the data length changing (i.e. when the data turn from 1024 to 0 the string losses the string termination '\0'). Hope it helps Stefano/******************************************************************************* * Function Name : Int2Str * Description : Convert an Integer to a string * Input : - str: The string * - intnum: The intger to be converted * Output : None * Return : None
