Posted on April 22, 2015 at 05:15Hello everyone! I am using STM8S105 and I don't understand the Illegal Opcode Reset function yet. How does it work? What is its function exactly? And which case do we use it? Thanks and best regards!
Posted on April 20, 2015 at 14:28I'm in the process of implementing a CAN-based ad-hoc communication protocol on the STM8S208C8 MCU. Slave devices in this systems perform auto-baud detection by monitoring the receive error counter and trying the nex...
Posted on April 12, 2015 at 18:55we have adopted stm8 in our application and get into production a year ago, which seemed ok, in reasonablly sum of quantity.but recent two batch of chips, mainly stm8s208, also messed up with stm8s105, give us big he...
Posted on April 08, 2015 at 19:39I have a new STM8S-Discovery board. When conneting it to PC USB port and loading ''discovery'' project and using STVD to start debugging, I got this error message: ** Connection error (usb://usb) [30100]: can't load...
Posted on March 26, 2015 at 09:32Hello, I have a question that don''t find the answer yet. Does the HSIRDY, HSERDY, LSIRDY flag go low level logic when I switch off HSE, HSI, LSI oscillator? I see they don't go off in debug mode. I use STM8S105C6. T...
