pi 2 Reading Multiple bytes in Raspberry Pi over I2C ... There is no need to modify the wiringPi source code to read or write multiple bytes. wiringPi provides a simple wrapper around a few I2C SMBus commands. WiringPi WiringPi includes a command line utility gpio which can be used to program and setup the GPIO pins. You can use this to read and write the pins and even use it to control them from shell scripts. You can use this to read and write the pins and even use it to control them from shell scripts. Serial Library | Wiring Pi Serial Library WiringPi includes a simplified serial port handling library. It can use the on board serial port, or any USB serial device with no special distinctions between them. [Serial port] The 'read()' will read 8 bytes blocks only ... Hi all I'm developing a C program which read from serial port. I'm using WiringPi library to handle Serial (open, close, etc) and the 'read()' method into a separate thread to read. Raspberry Pi and MPU6050 python example | Pi bits Raspberry Pi and MPU6050 python example In a previous post we showed an example of the MPU6050 sensor and a Raspberry Pi using wiringPi and C . This time its a python code example Raspberry Pi and I2C in c with wiringPi for PCF8591 ... So, you indeed need to read out 2 bytes if you want to know the current conversion by "forcing" two consecutive read actions one after the other. It's also again mentioned on the next page, second paragraph. WiringPi serialRead.c at master · WiringPi WiringPi · GitHub Join GitHub today. GitHub is home to over 36 million developers working together to host and review code, manage projects, and build software together. Functions (API) | Gordons Projects The rest is just code bashing – wiringPi supports that GPIO expander boards (it’s just a pair of mxp23017’s) but you’ll need to do some bit twiddling to assemble the 8 bits into a single byte (it doesn’t yet support a byte read function from off board hardware) Serial Library | Gordons Projects You read characters into a string (character array) until you get the terminating character or you exceede the length of the array (or have read as many bytes as you need to). You get a huge amount of flexibility with C, but you also have to do a little more work. wiringPi i2c help Raspberry Pi Forums I would suggest expanding the wiringPi I2C helper functions to include a function that would allow to pass in the "number of bytes" to read (and possibly write) as well as a close function. I realize one can use the standard read and close functions by including unistd.h but for the novice it would make wiringPi I2C library a better helper tool.
