The PsoC5 looks very capable, but I want to use it as a data capture front end.  I want to capture Battery Voltage (output from the Regulator/Rectifier) on my Motorcycle - the range will be between ground/batt -ve terminal, and around 17 Volts - with possible transient spikes from the alternator ?50V?.  Ideally I'd like to capture a relatively low rate 'background' voltage overview, with regular high sampling rate 'closeups' to see how the regulator is regulating, dumping the data to a 32 Gb SDCard possibly via I2C on one of my Raspberry Pi's .   Is this possible? and has anyone done anything similar I can adapt?

I've been doing this for a very long time ago for PSoC Creator 2.1

This project consists of:

1. The test signal generator, which has 2 modes

    a. the default signal is sine

    b. the signal downloaded from the file on the SD card.

2. An ADC (12 bits) whose signal is written in real time to a file on the SD card with a speed of up to 25,000 samples per second using DMA.

Each next entry is made into a new file.

It's here: http://mylab.wmsite.ru/moi-razrab/cypress-psoc/sd-logger-for-psoc5/

Unfortunately SD card value - no more than 2 (4?) GB

I can not answer you - I left to travel.
