AT91SAM7X – bit SAM Microcontrollers – Microcontrollers and Processors

The board is supplied “bare-metal” – no code, no OS. My problem is that I get a high impulse at power on of about 25ms, which is enough for the relais to switch. How would I go about doing so?

Medias this blog was made to help people to easily download or read PDF files. A very minor nit. Adam 2 11 I would appreciate any help on this issue. The users who voted to close gave this specific reason: You may be able to get help on Super User.

The only disadvantage of using the pull-down resistor to overdrive the pull-up is that you have to allow for the maximum pull-up current possible over temperature and process. I just recentely started working with a new board: Then the default state is for the datxsheet to be on and the internal pullup does not hurt.

How can I therefore connect to the board once I plug it in? So I looked at a pretty detailed data sheet and a summary of the data sheet, but have been unsucessfull so far of finding the information I want. I ended up using a hand full of Transistors to cover these issues properly.

If the former, which page exactly is that please? DarkFalcon Thank you for your answer. This pulse is a flat 3,3V signal, no power up glitches or something. There may be default firmware on the board which allows you to connect some other way, but most likely the usual way to connect while developing is via the JTAG connector.

I would recommend you start there. It turns on both FETs and can create problems. Protecting the IoT with Invisible Keys.


Stack Overflow works best with JavaScript enabled. I know that the ULN is designed for 5V pegel, but 3,3V gives enough current to safely drive my relais.

The datashert sheet says that this contains instructions for using the board with several different toolchains. From the Getting Started section of that: The data sheet contains instructions or the DVD?

For example, I would like to cross compile using a toolchain I’ve already installed – arm-none-eabi a simple hello world program at91sa7x256 C to load onto my board. How do I load an application onto the board’s flash?
