Create the hex file "psoc_forth. It consists of a 24MHz M8C CPU core, on-chip RAM and flash memories, multiple clock sources, a sleep-and-watchdog timer, and an interrupt controller. The development IDE is combined with an easy to use graphical design editor to form a powerful hardware/software co-design environment. The board is an open system design, which does not include a shielded enclosure. Ground/Reference of both devices should be made common. The project aims at communicating PSoC® 3 / PSoC 5 with UART HyperTerminal. Here is a PDF of my schematic. UART stands for Universal Asynchronous Receiver / Transmitter. interrupt controller (NVIC) and various. Atmega128 has multiplexed pins so we configure these if we want to use UART's. In this example, we will set pin PD0 and PB12 to be a GPIO interrupts. PSoC Creator - Post Build Command A call is made to the external VBS file under the PSoC Creator menu, Project, Build Settings using User Commands. The demo uses: The FreeRTOS GCC and Keil ARM Cortex-M3 ports. 001-89056 Rev. 5sec, timer1 is ticked -> program will come to timer1 interrupt routine (in part 2).
