Testcard first version
I thought I would share the first version of the testcard with you. At the moment it is not very complex but I will add further features. I am currently using about 2% of the available RAM on the FPGA.
Yes at the moment it is an 8x8 bit font which is then scaled by the code. The text is overlaid on the background. The biggest problem is the interlacing but I have that working now. There is not enough memory on the device to store a high resolution image on the chip so the text is written in real-time on the background. I have thought of storing the image on an SD card and reading that in real-time.

Be good if you could get a smoother font but I suspect its all down to coding it!
