Basic example main executiont.

Returns

ret - Result of the example execution. If working correctly, will measure active and reactive energy and RMS for channel A and for voltage stopping whenever an interrupt occurs and resulting in a stoppage of the measurement.

Returns

ret - Result of the example execution.

Basic example main executiont.

This example demonstrates basic ADMT4000 functionality by continuously reading sensor values and displaying them on the console.

Returns

0 in case of success, negative error code otherwise.

Basic example main executiont.

Brings up the full JESD204 link between the FPGA and the ADRV903X:

1. AD9528 clock synthesizer setup (DEVCLK + SYSREF)
2. SYSREF_REQ GPIO configuration
3. ADXCVR initialization (TX and RX)
4. AXI JESD204 TX and RX controller initialization
5. ADRV903X initialization (firmware load up to PreMcsInit_NonBroadcast)
6. AXI clkgen setup (lane_rate / 66 for JESD204C)
7. JESD204 topology initialization and FSM start FSM drives: MCS (LINK_SETUP/OPT_SETUP_STAGE1/2) + link enable
8. JESD204 link status readback

Returns

0 on success, negative error code on failure.

Basic example main executiont.

Brings up the full JESD204 link and demonstrates DMA data transfer:

1. AD9528 clock synthesizer setup (DEVCLK + SYSREF)
2. SYSREF_REQ GPIO configuration
3. ADXCVR initialization (TX and RX)
4. AXI JESD204 TX and RX controller initialization
5. ADRV903X initialization (firmware load up to PreMcsInit_NonBroadcast)
6. AXI clkgen setup (lane_rate / 66 for JESD204C)
7. AXI DAC core init — load sine wave LUT into TX DMA buffer
8. AXI ADC core init — reset TPL ADC core + IQ correction
9. TX and RX DMAC initialization
10. JESD204 topology initialization and FSM start FSM drives: MCS (LINK_SETUP/OPT_SETUP_STAGE1/2) + link enable
11. Start TX DMA (continuous sine wave to DAC)
12. Wait 1 s then capture RX DMA samples
13. Print buffer addresses for inspection

Returns

0 on success, negative error code on failure.

Basic example main executiont.

Brings up the full JESD204 link and starts the IIO application loop:

1. AD9528 clock synthesizer setup (DEVCLK + SYSREF)
2. SYSREF_REQ GPIO configuration
3. ADXCVR initialization (TX and RX)
4. AXI JESD204 TX and RX controller initialization
5. ADRV903X initialization (firmware load up to PreMcsInit_NonBroadcast)
6. AXI clkgen setup (lane_rate / 66 for JESD204C)
7. AXI DAC core init — DDS mode (IIO Oscilloscope controls tones)
8. AXI ADC core init — reset TPL + IQ correction
9. RX data offload — normal mode + per-capture XFER_LENGTH + RESETN
10. TX and RX DMAC initialization

Basic example main executiont.

Returns

ret - Result of the example execution. If working correctly, will execute continuously function iio_app_run_with_trigs and will not return.

Basic example main executiont.

Returns

0 in case of success, negative error code otherwise.

Basic example main executiont.

Returns

ret - Result of the example execution. If working correctly, will execute the code and end at error statement.

Basic example main executiont.

Returns

0 in case of success, negative error code otherwise

Basic example main executiont.

Returns

ret - Result of the example execution. If working correctly, will turn the status led's on and off in the while loop, set some values in the config 2 register, and then return 0.

Basic example main executiont.

Returns

ret - Result of the example execution. If working correctly, will show the user for each channels if there is digital input present or not. It also changes delay values for channel 3 and sets the state for channel 0 to OFF. If all these operations were performed correctly 0 will be returned.

Basic example main executiont.

Returns

ret - Result for the main execution of the example. If working correctly the device's channel 0 will be set to SOURCE mode and also have delay values changed. Counter values for channel 0 will be changed as well and printed afterwards. 0 will be returned at the end in case of succes.
