Hello, Can somebody please recommend me a logic analyzer for debugging my Arduino and Raspberry Pi projects? I need to analyze communication for I2C, SPI, etc., protocols. It should support both digital and analog signals. Since these are my hobby projects, I do not wish to spend much on the analyzer. Regards, Mayank

Hi there, I use the products from https://www.saleae.com both at work and at home and I like them a lot. The value for the price is very good. They have a decent built quality and a lot of features. BR, Alex

You could use a simple Cypress dev board and use Sigrok as pc software.
Hi, I also have several projects with I2C, TTL-RS232, SPI and more. For years I used the PC-Testinstruments LA1034 for I2C, reasonable satisfied with it. Biggest disadvantage is that it cannot use a very large buffer, e.g. only about 30 I2C characters Recenlty I bought the 4-channel Saleae Logic-4 for ~100 euro. This one works great, great user-interface, good specs (for me) and also 1 analog channel. It uses PC memory instead of internal memory and can store much more info; I stored >1000 Twi characters and did not run into any limits yet. The number of channels (4) is on the low side, that is why I now also bought the Saleae Logic-8 (~200 euro) which has 8 channels that can all be used for analog. Flip says to use SigRok and Cypress dev board. But the Sigrok site does not mention support for Cypress dev boards, Flip could you please shwo the location where you found this info ? Patrick
Ohh and there is also the Bus Pirate but as far as I remember it does not go above 100kHz for i2c when using as analyser
