Discuss STM8 microcontrollers, including SWIM, USART configurations, RTC usage, ADC issues, and debugging.
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...
Posted on June 13, 2012 at 14:47I'm relatively new to Raisonance/RIDE 7 for STM8 , and wondering that it seems not to support the ST-Link debug adapter, only it's own RLink. Is this correct ? Sorry to say so, but I consider this either poor performa...
Posted on June 03, 2012 at 07:04I am using the STM8S as an SPI slave device. The protocol I am using has a fixed sized buffer and I was thinking about using this interrupt to reset the buffer pointers. The data sheet suggests that this interrupt c...
Posted on June 11, 2012 at 16:36Hello, Wondering if anyone has been able to use IAR to put a table in ROM memory instead of the default RAM with init table. I would like something like: code int a[] = {1,2,3,4,5,6} or int a[] @ ''abc'' = {1,2,3,4,5...
Posted on May 10, 2012 at 13:01Dear all,I have some strange roundings with float values: for example when I write 0.05 in eeprom (calibration parameters) it becomes 0.049999997 when I read It.0.2 becomes 0,199999988.I use Cosmic compiler, I tried t...
Posted on November 10, 2011 at 08:56Hi all,I'm using USART and communicating via rs 232 protocol and trying to send formatted strings by using stdarg.h C library to use;va_list, va_start, va_arg, va_end..but I don't know which library is supposed to...
