-	The user program upload process is handled by the ROM monitor on the DIY Calculator side. But there must be a means of sending a program to the DIY Calculator. While it is possible to send a file with the terminal emulation program a GUI program is preferable. Furthermore, by having a dedicated program for this task it is possible to generate a check sum or use a protocol of choice for ensuring correct transmission. The transmission status (success/failure) can be displayed. This program should be written in "C" using the GTK library of GUI widgets to be easily ported to different platforms.

The DIY Calculator Hardware Project consists of several sub projects:

1. Creating the real hardware: a printed circuit board (PCB) with the processing chips, an LCD module, switches, and connectivity to a host computer
2. Implementing the DIY Calculator CPU together with supporting functional blocks within a programmable logic chip (a so-called "Field Programmable Gate Array" - FPGA).
3. Writing the firmware running on the hardware, including a ROM monitor
4. Adding a software tool for communicating with the hardware (e.g. uploading user programs)

On this page you will find information about the progress of the project as well as technical details.
