The problem is that the transactions are never ACKd. Part and Inventory Search. Dec 24 , 2: Arduino Robotics Lonnie Honeycutt. How do you get an MCU design to market quickly? How do i check whether an I2C device works?

There are pullups on the bus, it’s point-to-point, voltages are good, logic analyzer interprets the I2C protocol and everything looks fine address sent correctly, etc. Any suggestions that would help figure this out msp430f4538 be much appreciated. The eeprom should ack after a proper start and 8 bits, something very easy to see on a scope.

Radiation Detection Circuit 1. The only thing I can think of is that the MSP doesn’t see the ack because the sink of the eeprom can’t overcome the pullup.

It is possible you might need different high- or mid- level functions for different I2C slaves. If not, set the level down to like. If you have a digital scope, you shouldn’t even need a test loop. I guess by ‘internal functions’ you mean the I2C hardware and not an application included software I2C, right? But are you sure you’re interpreting the logic analyser data correctly not in reversed bit order? How do i check whether an I2C device works?


Let me know if you need it The meaning of the bytes after the first one depends on the I2C slave you’re using.

Check my I2C code for interfacing MSPf and MCP

Dec 242: I have a scope old MHz Tek but it’s not a sampling scope so a bit annoying to use on non-periodic signals. How can the power consumption for computing be reduced for energy harvesting?

I would not worry about looking at the buss with the scope from here unless to check voltage levels. Equating complex number interms of the other 5. My I2C stuff here I do have a logic analyzer though and have been using it.

How to upload a counter value to a website automatically 3. Short circuit protection in PCB design 5. I and a friend have gone over the data from the LA and compared it with the datasheet in agonizing detail and it looks right.

Are they 10k or so? CT measuring mmsp430f5438 with PIC 3. The time now is Does that LA show levels or just state? I do get a NAK though.

The one I use at my desk is an HPA. That’s the thing that NAKs.

The device just won’t ACK the transaction.
