Posted on January 24, 2012 at 08:25MCU: STM8S105C6Port: GPIOBBit: 2 GPIOB:2 is the only pin/bit set up for external interrupt, yet regardless of any edge sensitivity setting in EXTI_CR1, once an interrupt is invoked it is continuously invoked while ...
Posted on February 20, 2014 at 14:13Hi all,I cannot find what the meaning is of those E/H/L parts of the address! Nowhere in the datasheets are the abbreviations explained. I presume H and L are the High and Low ockets but what is E?I don't understa...
Posted on November 10, 2013 at 19:22 Hello, Is there any software library that allows to build USB hardware with STM8 microcontroller without any additional chip? I am looking it but I have not found anything so far. Such library would greatly impro...
Posted on February 28, 2014 at 12:07I set a floating-point (*data) , (*data) = (*data)/(pow(10,Strlen-3-DotPos)),(*data)=1234,pow(10,Strlen-3-DotPos)=100, the result was 12.33999 how did that happen? And I want to get an aprecise result 12.34. How ...
Posted on September 19, 2013 at 22:50I need to transmit to about 500 receivers, each one needing ~1.5kbps of data. So I need ~750kbps of total bandwidth. Can I use one transmitter per 5 receivers so that I have enough bandwidth (1.5k*5 = 7.5kbps w...
Posted on February 24, 2014 at 18:00Hi! I have been working with this discovery board for several weeks now and almost close to finalizing my design for a first prototype. But I always need to manually reset the MCU for my code to run from flash, I ...
Posted on February 22, 2014 at 14:34I wrote a program receiving and transmitting data to the microcontroller STM8 (Tested on STM8S103F3)But so far not implemented in full support of the protocol itself USB :( Source code and description in Russian ...

Posted on February 04, 2014 at 14:31My STM8 Cosmic compiler (32K limited) does not work anymore because it seems that the free licence is out of date (but it isn't: it will run out August 2014). Compiler Error is: '' </p> #error cpstm8 C:\Programm...
Posted on October 21, 2013 at 03:28I've checked the Option Bytes and the OPT3 byte is zero so the WDG_HALT bit is 0 which means that the MCU should enter Halt Mode without causing a reset when the watchdog is enabled. However a HALT or WFI generate...
