How to distinguish between POR and BOR in reset interrupt processing.
Posted on September 07, 2011 at 15:14Hi: STM8S105 is used, there have more reset sources according to manual. 1,When power on, if reset interrupt is enable, first enter into POR, then enter BOR,POR is off. 2,When power down, if reset int...

GPIO in interrupt handler
Posted on August 30, 2011 at 02:22I'm trying to create an interrupt handler that will toggle an LED on and off very quickly (as a basic test, my end goal is to eventually do much more than that). Right now I have an interrupt handler which is confi...

Looking for example code TSL V.2.4.0 for STM8S105C6, STM8S103K3
Posted on August 22, 2011 at 11:33I try to modify code from TSL V.2.4.0 in ''Example01_STM8S207_RC_5k'' for run on STM8S103K3 and STM8S105C6. Test on board STM8S discovery (for STM8S105C6). Follow TSL document to modify code but it not work. LED is ...
I2C not clocking address onto bus in master mode
Posted on August 21, 2011 at 23:52Hi, I have set up the input clock , enabled the I2C peripherial clock and the peripherial itself. I have executed I2C-Init() with the desired parameters. The peripherial sends a start bit, and recognises this with...
