 ====== Analog Inputs ====== ====== Analog Inputs ======
-Analog inputs provide ways to measure real analog data from external systems. OpenLogger has 8 single-ended analog inputs with their own recommended ground pin. Each input is designed to accept a voltage range of -10 V to +10 V (with protection up to ±30 V and has 16 bits of resolution and a bandwidth of 50 kHz. OpenLogger can then log all data onto the local SD card at 400 kS/s, stream and/or log data over USB at 200 kS/s, or stream and/or log data over WiFi at 10 kS/S.+Analog inputs provide ways to measure real analog data from external systems.

-Function ​The OpenLogger has a single channel 2 MS/s, 10-bit function generator. An R2R resistor ladder with 1% resistors is used in place of a DAC. /* Due to the nature of resistor ladders, it is possible to have a missing code for steps larger than 3 mV or encounter propagation delays, most notably when switching between the values of 0x1FF and 0x200. The channel uses 10 IO pins on the PIC32MZ to generate the output through the resistor ladder and a DMA channel that is shared with the Logic Analyzer at the highest priority level to transfer data and a PWM output to control the offset voltage level. */ +The OpenLogger has a single channel 2 MS/s, 10-bit function generator.
