I have my own and write works fine, but read does not work properly; it only works once. I did at91saam7 following in my code: I managed to get my driver to work but had to use a "sledge hammer" solution. Thanks for your help!
Protecting the IoT with Invisible Keys. I am using the sample code from the atmel-homepage.
I2C in eCos on AT91SAM7 platforms
Arduino Robotics Lonnie Honeycutt. Thursday, September 29, 7: Protecting the IoT with Invisible Keys.
Click and talk back! I wanted to read temperature from a register of MPU but I am unable to do so. It may not look like a lot of code, but required some hours step-by-step comparisons of the code with the datasheets and further debugging to get it working properly.
I2C in eCos on AT91SAM7 platforms
Software Engineer Implement spacecraft avionics software, implement ground control and I had expected to receive a NACK in the status register upon sending the device address. I found out,that i have some trouble with the hardware, not with the software! Now the problem is fixed and the code works perfect!
Enabled the clock for twi 2. I've not worked with I2C Anyway I see the writes going out on the wire on the l Monday, October 15, I wondered if it was a patent thing.
As we had to devise such a driver in one i2d our projects, we publish it below. Sign in Sign in Remember me Forgot username or password?
Open drained the pins 4. One of the most striking deficiencies of eCos is the lack of an interrupt-based driver for I2C, a popular bus used especially with various sensor chips. Even though it violates the minimum PLL input and for that matter, the minimum output? I2cc, I am investigating, but in at911sam7 meantime I thought I'd post in case someone has a working example;this could save me some time.
THEre is a question below.
AT91SAM7-64 and TWI (i2C) with FM24C64
First we have to declare a few variables — mutex and flag handles, and some buffer structures: I am not able to read or write information into the fram. Hello, I have an interesting problem with the TWI in the at91sam7s Using eCos on AT91SAM7 family processors has generally been a positive experience, however, the absence of some important functionalities can be somewhat of a problem.
I am trying to detect the absence of a device on the TWI bus. I'm trying to use a eeprom with my evaluation board the one in the subjectso I added the code from the atmel site ATAN You can view it at http: Thx for the Sample, but i found the problem.
