Try resetting the computer and try the procedure again, step by step. The bootloader should still be functional. It didn't work and now the device does not start? The HEX file does contain the full version of the oscilloscope, so you can always program back the original firmware.ġ1) I tried updating the firmware using the USB bootloader. 910-4094 49.99: e L\WIAM Prewired Digital voice recording and. Minimum system requirements: 386, 4MB of RAM, SVGA graphics, Windows 3.1 or above. ProtoLab also includes a variety of pre -designed circuits which you can use as additions to your own design. The evaluation source code does not contain the MSO application, but the source code provided can be used as a template for your own programs. ProtoLab will instantly test your circuit using five virtual instruments. The full source code is currently not open. Another solution would be to use a voltage translator chip, such as the 74LVC245.ġ0) The source code says "evaluation version", can I get the full version? An easy solution would be to place a 3K resistor in series with the 5V signal, this will work for signals with a frequency lower than 200kHz. On the non-portable variants, the logic inputs are not 5V tolerant. Since the input impedance of the device is 1Mohm, the voltage will is divided by 10 (This is the equivalent of using a 10:1 probe). On the non-portable devices, you can add a 9Mohm resistor in series to the input. The portable XScopes can use a 3.5mm to BNC adapter, and then you could use a standard 10:1 probe. The FFT analysis will be particularly useful to measure high frequencies. However, you can still measure frequencies up to almost Nyquist/2, i.e. +3.3V: Approximately 200mA, but this subtracts from the available current on the +5V line.ħ) What is the maximum frequency that I can measure with the XScope? 5V: Approximately 50mA, but this subtracts from the available current on the +5V line. +5V: Will be the same as the power source minus 60mA. This is the maximum current on each voltage: The XScope can also power external devices. Old hardware 1.4 and 1.5 cannot do USB firmware upgrades. A UART to USB cable is required for hardware 1.4 and 1.5.ĥ) Can I connect the XScope to the computer using the USB for firmware updates? Yes, you can use the XScopes PC Interface. Do not connect a 5V power supply and the USB at the same time.Ĥ) Can I connect the XScope to the computer to control the oscilloscope and get the data? Alternatively, the device can be powered by connecting a 5V power supply on the 5V pin. The device can be powered thru the micro USB port. (The AWG uses the DMA, so it doesn't need any CPU intervention). Yes, the waveform generator runs on the background. C Compiler, included in the WinAVR package: WinAVR at sourceforgeĢ) Can the waveform generator and the oscilloscope run simultaneously?.
