Quickly build your project our using award-winning Integrated Development Environments (IDEs) and reduce your software development effort with free software libraries and code generation tools.Texas Instruments Tiva C Series TM4C129x Microcontrollers is available at Mouser. Our software solutions are designed to let you take full advantage of our silicon by providing a simple, transparent development experience for the user. Microcontrollers frequently run operating systems that may not have built-in functionality to connect to local networks or the cloud, making IoT applications a challenge. FreeRTOS helps solve this problem by providing the kernel to run low-power devices as well as software libraries that make it easy to securely connect to the cloud or other edge devices, so you can collect data from them for IoT applications and take action.

The extract from the Quick Start Guide below shows the relevant pins.We will connect a logic analyzer to these pins. That's because these two are the I2C data and clock signals for the BoosterPack 1 slot on the LaunchPad. It talks I2C to the TM4C microcontroller on the LaunchPad.In this post, I sniff that I2C traffic that's going back and forth between the LaunchPad and BoosterPack.The I2C traffic in this is using the PD1 and PD0. The thermometer is the TMP006 (an infrared temperature sensor) from a SensorHub BoosterPack. I've defined a learning path for my previous post, I ended with a design that reads the temperature of an object. It's the first time that I'm working with this controller family and with TivaWare.

We're setting the IC in write mode. It says that the first thing we send to the IC is a 7-bit address, and a R/W bit.In our case, the address used by the в™њ is 0b1000001 and the R/W is 0b0.So if our BoosterPack has wired up the IC as option 2 in the address table (and yes, it does), the TMP006 will listen to traffic addressed to 0b1000001.Our 8th bit is a 0. In bynary that is 0b10000010.Let's check the manual. And it does!Here's a capture of a write command to the IC:The first thing the в™њ sends to the I2C bus is the value 0X82.

We'll see that register 0x01 contains a 14 bit value, and that the last two bits are to be ignored.So the real value we're retrieving is the first 14 bits, 0b1100001101.Check the TivaWare source sensorlib mp006.c for the TMP006DataRead(), TMP006DataTemperatureGetRaw() and TMP006DataTemperatureGetFloat() functions to see how we can turn this into the temperature of the object we're measuring.The easiest way to do this, is to put a breakpoint in your firmware at lineTMP006DataTemperatureGetFloat(&g_sTMP006Inst, &fAmbient, &fObject) When your debugger stops at that line, first step into that function to see what's happening at the I2C driver level (you will recognize the values from this blog).Then step over the next lines to see how the ambient temperature and that of the object's surface are calculated from that I2C traffic. If we turn to the datasheet again. Our I2C sequence is complete.0x0C34 is 0b1100 0011 0100, a 16 bit value. That's again the IC's address, but then with the R/W set to Read.В And we get the reply 0X0C 0X34 back (the most significant byte first, then the least significant one), followed by a NACK. It's a pointer to the register that we'll use.We're sending a 0x01, so we're addressing the IC's local temperature register.We then send a 0X83. In this case, it's expecting a Pointer Register Byte.
