LTC2508: 32-Bit Over-Sampling ADC with Configurable Digital Filter
NOTES This code is used in the case where DRDY triggers a hardware interrupt on Linduino, and then the data is read. This makes data acquisition faster. Set the terminal baud rate to 115200 and select the newline terminator. Provide an external voltage supply of +/-9V or 10 V. Drive MCLK with an external CLK source. Connect DRDY to INT1 pin. Connect QUIKEVAL_GPIO pin to the SYNC pin. 16 bits of configuration data: 1 0 0 0 0 0 0 0 0 SEL0 SEL1 0 0 0 0 0 In the Linduino code, data is continuously captured in the interrupt service routine and printed out to the serial console as hex values. Converting the data to voltage can be done later. The serially printed out data is logged into a file using TeraTerm. The data is read out, converted to voltage and plotted using a Python script. USER INPUT DATA FORMAT: decimal : 1024 hex : 0x400 octal : 02000 (leading 0 "zero") binary : B10000000000 float : 1024.0
