Part Number: ADS1278
Other Parts Discussed in Thread: ADCPRO
Dear forum user,
I use the ADS1278 for a multi-channel measuring system. The A/D converter is connected to a microcontroller which reads the data via SPI-BitBanging. Furthermore the ADS1278 is operated in TDM mode with low speed (about 10.5kHz @ 27MHz Masterclock). The reading of a channel e.g. channel 8 works perfectly. Unfortunately, reading out all eight channels does not work. I checked the SPI signals (!DRDY, SCLK and DOUT) in parallel on the digital storage oscilloscope, which looks plausible.
My DRDY Interrupt Handler and the SPI-BitBanging is fast enough so that all data is clocked out until the next !DRDY signal appears. I have a time reserve of about 40us, which is already good (see the attached DSO Screen)
Therefore my request would be whether I can get an example code for reading the ADS1278 or from the ADS1278-PDK. In other postings the sample code was sent by e-mail:
Thank you very much for your support
