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:
- Creating the real hardware: a printed circuit board (PCB) with the processing chips, an LCD module, switches, and connectivity to a host computer
- Implementing the DIY Calculator FPGA together with supporting functional blocks within a programmable logic chip (a so-called "Field Programmable Gate Array" - FPGA).
- Writing the firmware running on the hardware, including a ROM monitor
- Adding a software tool for communicating with the hardware (e.g. uploading user programs)
On the projects pages you will find information about the progress of the project as well as technical details.
