I²C or SMBus sniffer using Arduino

I had a need to continuously monitor a I²C bus, so I looked around for an Arduino solution, but didn’t find anything that suited my needs, so I wrote one myself.  None of the I²C-sniffers I was able to find … Continue reading

Server Power supply DPS-750TB

and how to get PMBus access from f.ex. a Raspberry Pi My favorite power-supply for almost anything is the Server PSU for Dell R510/R710/R910. It is a 750w 12v 60amp supply with 80-plus-gold standard,  you can get them for $10-20 … Continue reading

Server Power supply DPS-1200FB

Among hackers the DPS-1200FB seem to be the most popular choice for a powerfull Server PowerSupply 12volt 100Amp for less than $20 delivered. There is a lot of information available for this PSU.  So if you want to really get … Continue reading

MySensors Debug print @ 5.3Mbit/sec freeing Hardware Serial Port

MySensors provides a lot of useful debugging information on the serial port when MY_DEBUG is defined, I need to use the HardwareSerial for another purpose. but would still like to have the option to see the debug prints. which could … Continue reading

Debugging @ 5.3Mbit/sec (5333333 Baud) on stm8s microprocessors

In Debugging @ 5.3Mbit/sec (5333333 Baud) on Arduino and other Embedded systems  I describe how I handle debug print on Atmega processors like the one used in Arduino and 3D printers, basicly I let the embedded CPU transmit as fast … Continue reading

Stress testing 5.3Mbit/sec serial debug-stream from Arduino

I got the idea for Debugging @ 5.3Mbit/sec (5333333 Baud) on Arduino and other Embedded systems  which basicly let embedded CPU transmit as fast as possible and let the rest of the world adjust to whatever speed that happened to be.  … Continue reading

Debugging @ 5.3Mbit/sec (5333333 Baud) on Arduino and other Embedded systems

When debugging embedded system the long tried method has been to generously distribute printf() statements through your code, once everything is working as expected, you then have to comment them out or remove them. Over the years I have perfected … Continue reading
