From time to time you will need to check the signal on some pins. For that I've recommend you a logical analyzer like this one from banggood.com (affiliate link)
Sampling rate up to: 24 MHz
The logic for each channel sampling rate of 24M / s. General applications around 10M, enough to cope with a variety of occasions.
Logic eight inputs - can be collected at the same time they signal analysis, such as I2C, UART, sampling and analysis.
10 billion samples:
The logic can sample up to 100 100 million everything, so you capture even the most elusive events.
0.8V logic: 5V voltage, to accept the 5.25 V standard CMOS threshold logic low. 2.0 V logic high. The input impedance is approximately 1 MΩ to see more specificati$
Support for the latest version: 1.1.30 version

1 x USB-MINI line 1
|Analyzer connected to a PIR sensor|
After I've installed the 1.1.15 version for 64 bits and quickly connected a PIR on DCH0 I was able to see the signal in application. Off-course, this analyzer can do more than that, but it was a quick check to let the shop know that the product is working.
