I need to spy on an SPI connection for a long period of time which will require timestamps on the data to find approximate times of transmission. As this is not possible in Waveforms (which is a real shame) has anyone written any software that uses the SDK to do something similar to this? It would save me a bit a work if there was already an existing solution. - Callum
Hi there folks, great to meet you. Recently the company i work bought an Analog Discovery 2 to work with, and all I can say is - This is a great instrument, although I am using very small amount of its power. I have noticed something that lost me 2 days of work to discover that the problem is not my communication but in the way that the data is read by the AD2. The setup is like this - I have two boards communicating over I2C to each other and I am monitoring the messages in the Protocol part of the Waveforms. When i am sending large packets with more than 5 bytes of data there are some errors appearing on the tool but the messages actually are all right. My guess is that the discretization frequency is too small so it is getting errors in messages (i have seen this too when I have used the logic analyzer part of the software, although the I2C speed is 100kHz, when the scan frequency is smaller than 400kHz the protocol is not decoded in the right way.) There is no way(as far as I have tried) to adjust the frequency in Protocol mode. I am uploading pictures, hope it gets clear. Another thing is that the buffer that it stores the information from the protocol is quite large and the tool(waveforms) starts to work slowly, maybe it will be good to be able to adjust the size and flush the buffer more frequently. I will be glad to here from you is there a way to fix this issues. Thanks in advance.
