We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspberry Pi 4 ...
An LCD can be made to connect to a microcontroller using two wires with the aid of the I2C interface which includes pins for an SPI interface version for flexibility. The I2C LCD interface is used ...
Imagine you’re sending a piece of hardware to space on a satellite. Unless you’re buddy-buddy with NASA, it’s pretty unlikely you’ll ever be able to head up there and fix something if it goes wrong ...
Figure 1 shows a typical converter schematic. The I2C bus is connected to PIN5 and PIN6, and the SPI bus is connected to PIN9, PIN10, PIN11, and PIN12. PIN8 is used to control the transmission ...
A pair of Digitally Programmable Potentiometers (DPPs) feature 256-posiion resolution and I2C and Serial Peripheral Interface (SPI) Bus connectivity. The CAT5171 and CAT5172 are single-channel ...
