MSP430F5438 I2C DRIVER DOWNLOAD
The device just won’t ACK the transaction. If I’m not mistaken, on the 1xx USART this first byte is kind of hardwired to the I2C hardware, in that you have to disable it put into reset state if you want to change the bits chip-address, not memory address on the control byte. Introduction to Microcontrollers Mike Silva. The one I use at my desk is an HPA. On , at 1:

Look closely at the address.
Msp430f5348 I’m not mistaken, on the 1xx USART this first byte is kind of hardwired to the I2C hardware, in that you have to disable it put into reset state if you want to change the bits chip-address, not memory address on the control byte. CT measuring circuit with PIC 3. Our header files are static or dynamic library 1.
Not able to run Proteus Simulation after building project in CooCox 2.
Part and Inventory Search. DAC input digital signals, how to generate? I’ll give the scope a try and compare to the LA though. Arduino Robotics Lonnie Honeycutt.
It says you will see the ack on the buss and I’m taking it you did see the ack with the logic analyzer. How can the power consumption for computing be reduced for energy harvesting? Do you have a scope?
The time now is Thanks msp430d5438 the help. So if the first control byte is not ACKed, you have a problem with the control byte you’re sending so you can forget about the rest of the bytes. Sign in Sign in Remember me Forgot username or password?
It is possible you might need different high- or mid- level functions for different I2C slaves. After sending the start bit i am getting NACK whats the problem i dont understand if anyone find any bugs in mep430f5438 code please told me.
Short circuit protection in PCB design 5. I’ll also have a look at your code and see if we’re doing something differently.
Check my I2C code for interfacing MSPf and MCP
I guess msp430t5438 ‘internal functions’ you mean the I2C hardware and not an application included software I2C, right? I’ll try to provide a screen capture Maybe you’re using a two address byte code with a one address byte device.
Given you have a logic analyser, post the data you see on it.
Embedded Software Engineer Loft Orbital’s mission is to make space simple for organizations that need Does that LA show levels or just state?
So, I’m guessing you have not mspp430f5438 at the bus with a scope at this point It is skewed one bit when you load it into the MSP register.
How do you get an MCU design to market quickly? That’s the thing that NAKs. A bit more info And it doesn’t have to be fancy. Any suggestions that would help msp4305438 this out would be much appreciated. 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. Low Look closely at the address.
