  1. Any suggestions would be really valuable. I have a deadline coming soon. Thanks in advance,
  2. The same pin gives the above two responses at different frequency.
  3. Hello All, I am trying to acquire a waveform from one of my terminal of the ESP8266 microcontroller (GPIO0). I should be expecting a signal from the crystal at this terminal which is oscillating at 26 MHz. Can anybody let me know the correct settings to acquire the signal of 26 Mhz? The following are the steps that I performed: 1. Go to settings--> Device Manager --> select 2x 16K scope 2. Then click the settings (gear symbol) on the time settings box on the right side of the window 3. Here, I select Range Mode = Division Mode, Rate = 100 MHz, Samples = Default I have attached the snip shots below. The signal intended to measure should be in 26 MHz. It usually says samples lost- reduce the sample rate. Why does it say that? Please let me know the correct settings to measure this signal. The overall objective of measuring the time response on this terminal and maybe the frequency response at this terminal is to figure out which component in my custom board is behaving differently from the other boards which are tested as okay. Please let me know if there is a way to do it using Analog Discovery.
  4. Hello, I am a new user of analog discovery. I have an Arduino talking to my sensor through a 5v to 3.3 V level converter using I2C protocol. The code works fine and gets me the desired output on the serial port but when I try to connect the SDA and SCL lines to the analog discovery on the pin 7 (Data) and Pin 15 (clock) lines, I dont see any signals getting recorded. I am interested in seeing the clock and data lines with the addresses and data that is being written on the lines. But it either gives me Error status or no result after getting triggered. The snapshot is attached below: I wanted to know if I am following all the necessary steps in initializing the analog discovery. 1. Connect the wires to the 2 digital lines of analog discovery ( Pin 7,15 here) 2. Assign the right DIO pins as data and clock lines in the waveforms software. 3. Click the Red T button to set the trigger option. --> Start signal as trigger is the condition I used in the image below. but I also tried different trigger settings like, SDA = Ignore and SCL = Rising edge. Both of them gives me the error blocks as below. 3. Click Run button 4. Reset the Arduino. 5. Stop. I am interested in seeing the start, addresses in hex, ACK/ NACK signals labeled. Can anybody tell me if there is some required program to be run before I able to see them? Thanks & Regards,
