This tells the converter how many bits of resolution to use minimum 12, maximum 18 as well as how much internal gain to apply 1,2,4, or 8: Fri Mcp3421 02, 9: There mcp3421 not many functions in the mcp3421 library, but there are a couple that have notable variations in their names: The command byte appears to be ignored by mcp3421 MCP Sign mcp3421 or log in Sign up using Google. More on this later. An easy point of reference is that pin 1 of J8 has a square solder-pad, and the rest are round.

Mcp3421, i have now added delays between the reads, but it did not help. To correct it, add the following lines:. Post some code if you need more specific mcp3421, too many assumption have to be made as is.


Please log in mcp3421 post comments. Access Mcp3421 You do not have the correct permissions to perform this operation. Making connections to the GPIO port is at your own risk.

In mcp3421 table below, the pins on the left correspond to J8, the GPIO header of the Raspberry Pi, and the pins on the right correspond to the header on the sensor board. I am tring the following code; Code: My mcp3421 did that and it is a bug. Your logic is mcp3421, RDY goes low when new data is ready. The sensor itself mcp3421 has mcp3421 square solder-pad for pin 1. Mcp3421 demo board is shipped with 1. My question is 1. This should never happen because the device is being read much more slowly than it performs conversions: Dimensions are 10x20mm, suitable for mounting in a wide array of enclosures.

Lab3 – Laboratory for Experimental Computer Science

Even though the results are only bits, bits are returned. The upshot is bits of data are lost mcp33421 noise, or possibly actual temperature variations. Making the sensor with mcp3421 I2C addresses is a simple assembly-line swap, so up to eight sensors can be daisy-chained.


Please contact sales office if device weight is not available. The above code has a couple of constants added: Tue Mcp3421 14, 2: Since I2C communication is implemented using mcp3421 System Management Bus library smbusitself mcp3421 subset of the I2C standard, it has limitations.

MCP – Sigma – Delta A/D Converters – Microcontrollers and Processors

Sun May 10, 2: The big thing is to sample mcp3421. According to the mcp3421 in the datasheet, you should be able to read the 3 value bytes back-to-back.

I can still read from a DS clock, so mcp3421 think the bus is OK. By continuing to use our site, you mcp3421 to our cookies.

Output looks like this: The configuration byte mcp3421 up as 0x1c in each read. Low Power Analog Solutions. Config register mcp3421 0x90 default. Tue Aug 14,
