Coffee and a Chat


STM8S-Discovery Board - CH Ting
"Many of you might have gotten STMicroelectronics' STM8S-Discovery evaluation board free at this year's Embedded Systems Conference. It has an 8-bit microprocessor, the STM8S105C6T6, and a USB link. I looked into it and found the microprocessor is similar to the 68HC11. So I dug up my 68HC11 eForth implementations and am trying to port it over. I will report my progress. I hope to have a working eForth on it for demonstration at the meeting. STM is selling this board at $10. At this price, I can tolerate all the shortcomings in this chip."
