https://community.nxp.com/t5/i-MX-Processors/Linux-I2C-custom-message-frame-sending/m-p/1487041#M192346 <P>Hi!</P><P>Is it possible to send out a custom message frame on I2C dev from Linux? I am using an i.MX7D board and i would like to use "/dev/i2c-0" device like a simple "serial tty" to "write(fd, bytes, count)". My goal is to send out a single byte for example 0xAB on I2C without any specific slave address and without automatic stop/start bit inserting in my frame.</P><P>So i like to make my full custom I2C frame then send it out from Linux. Is it possible, is there any user-space programing techniques in C/C++, Python or any API for it in Linux?</P> Sat, 09 Jul 2022 12:25:37 GMT Livius 2022-07-09T12:25:37Z https://community.nxp.com/t5/i-MX-Processors/Linux-I2C-custom-message-frame-sending/m-p/1487041#M192346 <P>Hi!</P><P>Is it possible to send out a custom message frame on I2C dev from Linux?
