Pick one up today in the adafruit shop! -> This is an example for our Monochrome OLEDs based on SSD1306 drivers. take a look at the Micro-controller Performance Differences on the FAQ Wiki page.The following code should load: /********* There are better options that are well tested and probably your time figuring out how to get a DUE clone working is worth more than these cost. and all looks good! See Taijiuino link below, just in case: But I found your software on the net and it made no sense to waste time developing what is already out there, I had an old Mega 2560 for testing. I had a solution based on those that was working pretty well (just tracking very well and goto with commands from PC), and I could go to very fast frequencies for step output based on assembly code switching the voltage up and down in the same interrupt cycle, with over 16 degrees per second slew.

We just installed a pair of SDSK 2331S ELN on a mount capable of 150Kg instrument load and these babies ROCK! Thank you. At the moment, for thos who need a complete solution consisting of motor+driver my suggestion would be to get Teknic Clearpath. I travle to Shenzhen very often on business and I plan to visit Leadshine soon. In Shenzhen there are many suppliers of motors and drivers, and most can be found on Alibaba and Aliexpress. Also can be found on aliexpress, do not have extensive distribution network. The address is optional for master devices. The syntax for this is Wire.begin (address). After including the library, the next thing to do is to join the device on the I2C bus. In the sketch above, we do that with include .I have used their MCAC706 drivers (now maybe discontinued) and 42JSF330AS-1000 motors. To use the functions in the Wire library, we first need to add it to our sketch. Can be found on aliexpress and also have distributors around the world. External drivers can be connected to any motor in an easy way. They offer servo motors with integrated driver, and external driver solutions. Is the best company, especially because they have a reasonably good software to set up the system. I also have used the following suppliers from China. There are several good options which i tested: Is a very good driver for brushless servo motors, I have used this on several mounts in conncetion with Pittman ELCOM SL and with Maxon motors. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. I had a solution based on those that was working pretty well (just tracking very well and goto with commands from PC), and I could go to very fast frequencies for step output based on assembly code switching the voltage up and down in the same interrupt cycle, with over 16 degrees per second slew. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. I am also looking into testing Arduino Due platform, since I have several Taijiuino boards (better Arduino Due with RTC oscillator and some interesting changes), but maybe not worth the pain. Is there any way I can check the PPS signal is received and used? I will look into, should not be a problem to change my setup to that. I am not using PEC, so I will take a look at Digital 2 and test it. I had a DS3231 around and I used it with Classic.h just changing the #define RTC_OFF to #define RTC_DS3231 and all works well. Thank you Howard I am using a Mega2560 board with external motor drivers (Chinese brushless servo motors) so I just need to provide the step/dir/enable input.
