Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
Posted on July 19, 2012 at 20:18Hello, I have question about parameter of MCU STM8S 103F2: ''NRW - Erase/write cycles - (program memory)'' I read document: ''Specification: STM8S103K3 STM8S103F3 STM8S103F2'' (DocID15441 Rev 9/ CD00226640.pdf ) on ...
Posted on July 07, 2012 at 20:24I found something very funny/weird when using TIM1 to measure the frequency of a signal: Set TIM2 and TIM1 to use the same prescaler (e.g. 8). TIM2 is configured to generate PWM with period 10000, in this case resulti...
Posted on June 28, 2012 at 02:29Hi all,I'm moving a design from STM8S105 to STM8S207.I'm thinking of raising the clock speed from originally 16MHz to 24 MHz in order to get more MIPS from the core.However, for clocks > 16 MHz, the flash memory requi...
Posted on May 22, 2012 at 17:59I'm starting to work with STM8. I'm not finding a way to configure the ports as pull-down.

Posted on June 27, 2012 at 05:08I am using STM8S103 to measure three channels of voltage signals named vs12, vs5 and vs3 respectively. Timer 4 is enabled to generate interrupt every 10ms and three voltage signals are measured alternately. That is, i...
Posted on May 30, 2012 at 10:35I'm coding my 3rd testing project on stm8, to be exact in 2 different mcus, 103 and I'm using cosmic compiler, and i didnt have any problem with the previous 2 projects (because i didnt verify the size).The problem is...
Posted on May 23, 2012 at 13:00I am using STVD 4.3.1 with ST-LINK and windows 7 32bit.Most times I try to enter debug mode I get COMM TIMEOUT ERROR. Clicking STOP and trying again just results in the same error over and over again.The only way to c...
Posted on June 21, 2012 at 13:54 Hi all, I'm trying to write an update routine for an STM8S003F3, so that it can be updated over SPI. I'm pulling 128byte chunks of data from a routine in ram, then attempting to write them to the mai...
Posted on June 18, 2012 at 17:23Hi everyone,I have serious problem about TIMx_SR1 register. This register is 0x07 at the normal time. I finished my code and i am using timer3 everything is ok. Sometimes my timer3 working wrong and i found problem.T...
