Raspberry Pi B+ GPIO Speed using Oscilloscope - YouTube
Interfacing an SPI ADC (MCP3008) chip to the Raspberry Pi using C++ (spidev) Also the SPI peripheral on the Raspberry Pi has only two chip selects (CS0,CS1 pins) and can therefore only be used to attach a maximum of two SPI slave devices to the Raspberry Pi. At maximum spi clock speed and calling spiWriteRead as fast as possible I doubt

Raspberry Pi’s GPIO Speed. 28. Mai 2014 Oliver 1 Kommentar. This way you can control external hardware like LCDs or writing data to external SRAM faster than utilizing SPI. So we were interested how fast the Pi can really switch these pins. Clock GPIO Pi Raspberry Raspi
Interfacing an SPI ADC (MCP3008) chip to the Raspberry Pi
Getting my Raspberry Pi set up for high-speed serial UART communication I bought a Raspberry Pi to work together with my rooms moodlight. The current system uses an FTDI USB to RS485 converter cable with a full-blown linux PC pushing 1Mbps of data over that to drive the animations.

Raspberry Pi SPI and I2C Tutorial; Raspberry Pi SPI and I2C Tutorial This tutorial will walk you through getting the I2C and SPI interfaces of your Raspberry Pi working. These interfaces aren't enabled by default, and need some extra configuration before you can use them. (bus, device) # Set SPI speed and mode spi. max_speed_hz = 500000

OLA 0. 10. 3 with the SPI / GPIO outputs on a Raspberry Pi 3B From the last post on that thread: Incidentally, spidev0. 0-spi-speed in ola-spi. conf does not set the clock speed correctly - actual speed, measured with a scope, is a factor of about 1. 6 times slower.
