Page 4: Important Safe-Handling Information
The list here describes common causes of failure found on boards returned to Diamond Systems for repair. This information is provided as a source of advice to help you prevent damaging your Diamond (or any vendor’s) embedded computer boards. - Page 5 Overvoltage on digital I/O line — The digital circuitry can be damaged if a digital I/O signal is connected to a voltage above the Vega’s maximum specified voltage. On most of our boards the acceptable range of voltages connected to digital I/O signals is 0-5V, and they can withstand about 0.5V beyond that (-0.5 to 5.5V) before being damaged.

Page 38: Analog I/O Operation
6.1 A/D Input Ranges and Resolution The Vega baseboard uses a 16-bit A/D converter. This means that the analog input voltage can be measured to the precision of a 16-bit binary number. The maximum value of a 16-bit binary number is 2 - 1, so the full range of numerical values that you can get from a Vega baseboard analog input channel is 0 - 65535. -

MUXEN1/0 is high when the mux enable outputs are MUXEN[1:0]=10b (i.e. channels 15 to 8 are selected). It is low when MUXEN[1:0]=01b (i.e. channels 7 to 0 are selected).

Page 42: A/D Sampling Methods
6.5.1 Sampling Modes There are several different A/D sampling modes available on a Vega baseboard. The desired mode is selected with the FIFOEN and SCANEN bits at the FIFO Control register (Base+7), and the ADINTE bit in the Interrupt Control register (Base+9). -
Page 43: Fifo Description
On Vega, this number is programmable using the FIFO Threshold register (Base+6). The usual value is 1/2 the maximum FIFO depth, or 1024 samples. Therefore, the maximum interrupt rate for Vega is reduced to 996 per second, which is easily sustainable on any popular operating system. -

Initiate an A/D conversion Wait for the conversion to finish Read the data from the board Convert the numerical data to a meaningful value Each of these steps is discussed in detail on the following pages. www.diamondsystems.com Vega SBC User Manual A.01 Page... -
Page 45: Select The Input Channel
6.6.1 Select the Input Channel The Vega baseboard contains a channel counter circuit that controls which channel is sampled on each A/D conversion command. The circuit uses two channel numbers called the low channel and high channel. These are stored in the A/D Low Channel and A/D High Channel registers (Base+2 and Base+3). The circuit starts at the low channel and automatically increments after each A/D conversion until the high channel is reached. -
Page 46: Select The Input Range
Alternatively, the value can be read as one 16-bit value, which is preferred since this method increases overall system bandwidth while reading data from the FIFO. For example: Data = inpw(base); // Where the MSB and LSB are read in one access www.diamondsystems.com Vega SBC User Manual A.01 Page... -
Page 47: Convert The Numerical Data To A Meaningful Value
A/D channel range (low channel, high channel). On Vega, the channel numbers range from 0 to 31. Some channel numbers may not be available, depending on the single-ended/differential configuration mode as explained on page 11. During interrupt- based A/D conversions, the channels being sampled must be consecutive in number. To sample only a single channel, set the low channel and high channel to the same channel number. -
Page 48: D/A Conversion
10b. If it is set to 0, then MUXEN[1:0] is set to 01b. If the CALMUX bit in page 1 is set (‘1’), CALEN goes high and all other MUXENx bits go low (i.e. there is no output from either mux). Otherwise CALEN is low. www.diamondsystems.com Vega SBC User Manual A.01 Page... - Page 49 They serve no functional purpose other than debug. Their values are also reflected in the corresponding read- back bits at base+6. Please refer to Diamond Systems’ Universal Driver 7.0 User Manual for information on using and programming the analog I/O.

Page 50: Pulse Width Modulators
7. PULSE WIDTH MODULATORS Vega offers four 24-bit pulse width modulator (PWM) circuits. The PWMs are programmed using a 24-bit PWM data register PWMD23-0 and an 8-bit command register PWCMD3-0 + PWM2-0 + PWMCD. Each PWM consists of a pair of 24-bit down counters named C0 and C1. The C1 counter defines the duty cycle (active portion of the signal), and the C0 counter defines the period of the signal. -
Page 51: Waveform Generator
To make the pulse appear on the output pin, command 0011 must additionally be executed, otherwise the output will be held in inactive mode (the opposite of the selected polarity for the PWM output). Please refer to Diamond Systems’ Universal Driver 7.0 User Manual for information on using and programming the pulse width modulators. -
Page 52: Digital I/O Operation
9. DIGITAL I/O OPERATION Vega contains 30 3.3V digital I/O lines organized in four groups: A, B, C & D. Groups A to C consist of eight signals each and port D consist of only 6 signals. The direction of each port is independently programmable. All bits on all ports are individually programmable for input or output with register bits DIRA7-0, DIRB7-0, DIRD7-0, and DIRD7-0. -
Page 53: Counter/Timer Operation
Clk1 Input Out0 Output Please refer to Diamond Systems’ Universal Driver 7.0 User Manual for information on using and programming the digital I/O. 10. COUNTER/TIMER OPERATION Vega offers eight 32-bit counter/timers with programmable functions. The counters are programmed using a command register at address 5 in the counter block, a counter number register at address 4, and a 32-bit data register CTRD31-0 at addresses 0-3. - Page 54 Reset means all registers and settings are cleared to zero. A command of 0xFF will reset all counters (although the precise command is 0xF1).. Please refer to Diamond Systems’ Universal Driver 7.0 User Manual for information on using and programming the counter/timers.
