ForthDuino from Taiwan - CH Ting
"Friends in Taiwan FIG sent me a ForthDuino board with a STM32F407, an impressive ARM chip with 1MB of flash and 192KB of RAM, used on the STM32F4-Discovery board ($16.95 from Amazon). I am trying to move the SAM7eForth over, but so far, no luck. The MDK-ARM toolchain from Keil is overwhelming. The chip is overwhelming, too. I will bring the boards to the meeting and talk about them. If I can bring eForth up, then we can celebrate."

“I got the interpreter working on the STM32F4-Discovery board and am now working on the compiler. I will demonstrate the eForth system at the meeting, whatever shape it is in.”

Exploring 1-wire devices on the GA144 - Franklin Amador
This presentation will describe a method to interface the Dallas Semiconductor high-precision one-wire digital thermometer (DS18S20) device with the EVB001 evaluation board. The hardware and software interface, discussed in a future app note, uses arrayFORTH and polyFORTH, respectively.
