Does anyone have any recommendations for some free and quick source code for a packet interface. I'm looking for something along the lines of start byte, n-byte length, n-bytes of data, checksum, end byte.
I want reliable communication that will drop packets and/or not get hung up on code...
Hi everyone. I'm trying to determine the frequency of a incoming signal at roughly 7KHz. This signal is correctly identified using a scope and is at correct logic levels. I am using the 16bit Tachometer digital block which adds a second interrupt. It is basically a 16 bit timer with the...
I stumbled upon this o-scope in my search for an inexpensive oscilloscope to buy. I have researched all kinds of important factors such as bandwidth, sampling rate, vertical gain and resolution,etc... Before I go out and buy something without thinking I figured some people here who have used...
I am trying to connect this digital to analog converter to the micro-controller with a small issue. First off, I the MCP4922 has 2 seperate 12 bit channels and the first one I send data to works while the other way stays near 0 volts. I have played with the CKE and CKP values which change...
I am trying to calculate the frequency of an incoming signal on the dspic30f4011 micro. I have setup a functioning pwm signal to test the incoming signal on. I believe my code is picking up the difference between the time captures of the signal, but I'm not sure how to calculate the frequency...
I am going to build a laser spyrograph toy that can be seen here.
**broken link removed**
I actually have quite a few questions so bear with me. thanks
First of all, is there a difference between the three lined schematic symbol that appears (I think as ground) and the one with only two...
