Build your own JTAG

Hi, i'm new in the ST7 microcontrollers, and i love to make my own thinks, so far i'm getting some troubles to find softwares(to write the program in C, and write it into the microcontroller), the JTAG schematic(diagrams, connections, components, ect).

Try the Cosmic compiler available from Cosmic Software with their Integrated development environment IDEA. You can download a memory limited fully functioning version which you will have to register to use.
