hai all, i will working to CC3220SF launchpad i will try to interface at Load cell using Hx711 Amplifier i have some error will be occur , how to resolve this issue any one work hx711 at CC3220SF or Any launchpad Please Share the Library file. and One Wire Digital Temperature Sensor - DS18B20 working source code Thanks Selva
Some time back I ordered an INA125P Instrumentation Amplifier in order to fool around with a cheap, broken "postal" scale that I had. It arrived and I promptly put it away and forgot it about it. So the other day I was digging through my junk box, saw the scale, and decided to tear it apart. Since it is getting near Halloween, and I knew my grandchildren would be interested, I wrote a little sketch in Energia to estimate the amount of candy in a bowl. Here is a schematic of the circuit. It "works" but given my skills it may not be best. This being a MSP430 project I hooked up the sleep pin on the INA125P. I also made it where I could change out Rg, the gain controlling resistor, easily. Once I had it working I made up a little BoosterPack that goes on the bottom of the LaunchPad. The INA125P sits between the daughter board and the MSP430F5529 LaunchPad - you are looking down on the male pins in the photo above. I hot glued a piece of cardboard on the bottom so as to reduce the chance of shorts and provide a reminder on how to connect it. Below is a view from the bottom with it connected up to the LaunchPad and the scale. The sketch is here on github. There is a little calibration routine it goes through when started up where it asks for the empty bowl and then a known quantity of candy to be placed into it. After that, it displays on a SHARP96 BoosterPack. I thought about connecting it up to the IOT, but after due consideration decided I didn't want the neighborhood kids knowing how much candy I have left.
