![]() ProcessOne curates two monthly newsletters – tech-focused Real-time Stack and business-focused Real-time Enterprise. I will continue the programming to add the mapping functionality and a nice demo mode. I hope to be able to drive it with my smartphone soon. I will use it for I2C debugging and visualization. ![]() It is a 34 years old Circuitmate 9020 (bought in 1985). One of my colleague has been cleaning his lab, and he asked me if I was interested to have an old 20 MHz oscilloscope. F : Buttons and their pull down (3.3V or 5V depending on the GPIO).B : Level shifter between Arduino (5V) and Raspberry Pi (3.3V).In Liège, we would say "mettre une noquette de colle" which translates to "put a knob of glue". I was skeptical at first but really much effective and fun.

I've used the I2C scanner provided by the Arduino documentation. I2C devices are recognized by the Arduino (5V) and the Raspberry PI (3.3V) with the help of a level shifter. I☬ is a bus communication that allows multiple device to communicate with each other. The perfboards are fixed on metallics spacer bars to avoid shortcuts. ![]() It is really useful because it decrease the wiring. The aim is to connect it to the negative pole of the battery. I have been advised to use an epoxy base coated with a copper layer. Microcontroller must switch between protocols. The sensor cannot be addressed by I2C protocol, however, the sensor can be connected to an I2C bus without interference with other devices connected to the bus. The serial interface of the SHT7x is optimized for sensor readout and effective power consumption. The documentation of the SHT71 explains why the sensor has no I2C adress.
