I had a thought about this while at work yesterday. Everything in the SDRAM code uses positive edge clocks - except for the data reading. With luck, that would be the only thing that needed changing... (More)

One of my earlier projects had an SPI slave, but this needed to be an SPI master - so I wrote one that had my requirements: (More)

I hadn't soldered the audio part yet (except for the connectors), so the first job was to solder on the WM8759 and the accompanying resistors, capacitors and inductor.  (More)

Like the SRAM controller and rotary encoder, I'd done another project with SDRAM, so I knew roughly what to do. The only changes I needed to make was in the address space. The earlier SDRAM chip was 64Mbit; this was 256Mbit, so I had to add A[12]. (More)

The switches and rotary encoder are fairly simple pieces of work to do - however, I wanted to use them instead of the debugging port (in conjunction with the LCD).  (More)
