Posted on January 30, 2013 at 11:34hello, i try to make a connection between the stm8s207 and an pcf8574. the problem is with the software, because i can control the pcf8574 with an AARDVARK analyzer. when i send a start and an adress (40) for pcf85...
Posted on March 19, 2012 at 19:01I trying to develop device using STM8S105K6 MCU and found something very strange. If I press reset button (connecting NRST to GND) all if working fine. But If I just turn off/on device power, MCU is starting (timer ...
Posted on February 01, 2013 at 12:05Hi. I'm using the Cosmic STM8 compiler (''free'' version, v4.3.9) and it appears to generate unexpected results for the following test :- static char test(unsigned int x, unsigned int y) { return (int)(x - y) <...
Posted on February 05, 2013 at 05:00I have recently started working on STM8 platform. Using RIDE and STVD with ST-LINK.STVD is heavenly slow on Win 8. Forget compilation time it takes 4/5 seconds just save a file. I came across similar discussion h...
Posted on February 04, 2013 at 22:44I've tried both the 16 MHz HSI and 24 MHz HSE with the STM8/128-EVAL board, and I can only divide TIM4 down to an approximate 5-microsecond tick resolution. Is this correct? The settings I'm using with the 24 MHz ...
