Tricorder v7 working great
October 27th, 2008
After dealing with a few ugly hurdles (mostly having to do with a horrible new serial module in the MSP430F2618), life is starting to look really good. The filesystem is working very nicley with a shared serial bus with the accelerometer (SPI) and the bioImpedence circuit (AD5933 impedence measurement IC; I2C). See how nicely they play together..
And even the SpO2 signal is finally looking really /really/ nice..
Though that data is from a transmissive sensor. We’re still investigating the efficacy of an upper arm reflective sensor, but I’m quite pleased given the complexity of the new device.
