Welcome to RaspberryAda project

Raspberry Ada is an I/O toolbox for Raspberry Pi board.

General Information

The project is based on mapping from Broadcom BCM2835 datasheet for ARM Peripherals. The project intention is to map all the chip using the datasheet available from
http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf. This datasheet Windows link is replicated in related folder to become easier the development.

There are some corrections to be made in the BCM2835 datasheet, which are described in http://elinux.org/BCM2835_datasheet_errata#the_BCM2835_on_the_RPI. This page is also replicated in pdf form in related folder, file BCM2835-datasheet_errata-eLinux.pdf.

And finally we add the file related\BCM2835-ARM-Peripherals-Fixed.pdf with the corrections indicated in BCM2835-datasheet_errata-eLinux.pdf, added to the BCM2835-ARM-Peripherals.pdf document. The informations from the errata document are indicated in comments in the main document.

Project Status and Goals

Each block is a chapter of the BCM2835 datasheet.

• Auxiliaries: UART1 & SPI1, SPI2 : Implemented.
• BSC : Implemented.
• DMA Controller : Under development.
• External Mass Media Controller : Future development.
• General Purpose I/O (GPIO) : Future development.
• Interrupts : Future development.
• PCM / I2S Audio : Future development.
• Pulse Width Modulator : Future development.
• SPI : Future development.
• SPI/BSC SLAVE : Future development.
• System Timer : Future development.
• UART : Future development.
• Timer (ARM side) : Future development.
• USB : Future development.
