The ARM datasheet only gives information about the processor. Although this is useful, it's not exactly what I needed.
I'm looking more for information about the BCM2835's hardware features. What is the IC's pinout? How many SPI, I2C, and UART communication modules does it have? What are the registers that control these modules?
Also, what about the GPU? It's not part of the ARM datasheet. The wiki doesn't say anything about it. http://elinux.org/Videocore
doesn't even exist. obarthelem-y, you said that the wiki seems to have an adequate level of documentation, but I'm not seeing any of it. Am I looking at the right wiki? Could you please provide a URL to the documentation?
This has been asked for and complained about many times if you use the search function. I have asked myself. Here is the answer, your not going to get it. Broadcom dosn't operate like Atmel and ST Micro there will not be a data sheet for the SOC, or the GPU. Therefore there is no URL for it. They don't have this level of transparency.
At first this really pissed me off, but for the price I'm just going to live with the fact that to use the Videocore I will have to address the drivers, and the same for the GPIO pins. If I need something more low level there are plenty of Microcontrolers out there like the STM32 and ATMega.
Edit: Also if this turns into another complaint thread about this SOC's "openness" I will have to lock it because there are already plenty of them on the forums.
