AAEON announced the UP 710S developer board, succeeding the original UP Board with enhanced capabilities and a more compact ...

The SparkFun I2C Expander Library makes working with 4-bit and 8-bit I2C digital I/O expanders very easy. These expanders can read or write four or eight separate I/O. This library supports using ...

When it comes to hacks, we’re always amazed by the aesthetic of the design as much as we are by the intricacies of the circuit or the cleverness of the software. We think it’s always fun to ...

As [Pat] discovered when mocking out a missing SPI GPIO extender, sometimes playing ... SPI can be wonderful in its apparent simplicity. Unlike I2C there are no weird addressing schemes, read ...

When input data differ from input register state, PCA9555 will trigger the interrupt signal to I2C master, right? In case I2C master connected eight devices of PCA9555, all of I/O port connected to ...

It’s very similar to the UP 7000 SBC with Intel N50, N97, or N100 CPU, but it’s designed to be slimmer so the 40-pin Raspberry Pi-compatible header has been replaced by 1mm pitch wafers exposing GPIO, ...

This board consists of tons of gpio pin which is used to connect many sensors ... These will help the bot to move it around the desk. The whole circuit needs 5V to run. So here I am using XL6009 DC-DC ...

KAGA FEI has announced the ES4L15BA1, an advanced Bluetooth Low Energy (BLE) module for IoT applications. Designed for next-generation IoT devices, wearable technologies and healthcare & medical ...

how can we rewrite/reconfigure the OMAP2 I2C driver omap24xx_i2c.c in U-Boot to performing "repeated start" (Sr) instead of "stop-start" (P-S) for I2C read access? I know there is this hint in the ...
