Each of the 8 signal paths consists of a low noise amplifier (LNA), a digitally programmable variable gain amplifier (DVGA) and a 12-bit, 40 to 50. The direct memory access (DMA) controller (see block diagram in Figure 11-2) allows movement of data from one memory address to another, across the entire address range, without CPU intervention. I'm using the MSP430FR5725 and I need to read in multiple analog inputs (A1, A14, A15). This allows you to connect many analog signals to the MCU (say 3 temperature sensors). The lab uses concepts learned in lecture to design and build a power supply. These will be great for creating small sensor modules or miniature output modules with low power and very low complexity. And if you remember the video game wars in the 90s, 16-bit is way better than 8-bit. The block output emits analog voltage in varying ranges based on the conversion resolution selected for the ADC in Configuration parameters > Coder Target > ADCx.

The trick when using multiple analog sensors is to read them twice, with a small delay after each read (10ms is good), then discard the first reading. DMA of multiple SAR ADC channels on PSOC 4. The ADC used in this example is the MCP3008. The Photon Audio Sample 3 does a single channel double-buffered ADC DMA read. The circuit diagram of the interface can be found here. The I/O pins can also be configured to be general-purpose, digital input or output (GPIO) pins. MSP430 Basic Clock Module zClock Signals: zACLK: Auxiliary clock. If you would like to change the channel, change the ain of the ADC setting structure (adc_channel_setting_t) and the argument of the channel setting function adc_channel_setting. 12-Bit High-Speed, Multiple SARs A/D Converter (ADC) 2. One problem with logic analyzers is the massive amount of information that it generates. So if you need A15, A14 and A1, the sequence will sample ALL channel sfrom A15 down to A0, even though you don't need most of them.
