ARM Cortex-m3 - Remote debugging using GDB (1)
One of the things I’ve found more interesting and useful in Robotics is debugging.
Most of the time we use to print out traces through a serial port and, the luckiest ones, who own a JTAG emulator, can dig deeper into their bugs but always with a cable plugged.
So, now thanks to the excellent Espardino project and […]

SPI Communications - Slave Core VHDL
SPI (Serial Peripheral Interface) protocol is a synchronous serial data link which operates in full duplex mode. It’s got a higher throughput compared to I2C or SMBus and it’s very useful for high speed short-range communications.
The SPI protocol specifies the following signals:
SCLK — Serial Clock (output from master)
MOSI/SIMO — Master Output, Slave Input (output from […]
