![]() ![]() Also, i was wondering how to know if the microcontroller is actually talking to the computer or not.like how do i verify if it is working correctly? Also, i do not know assembly and well i've learned a little C++, but I don't know how far off that is from the C you have to use to program these microcontrollers. Okay and the other thing is.once i have made the programmer, I was wondering what software i should use to program the microcontroller. However, this computer only has a parallel port so hopefully the programmer can stick to using that. ![]() Oh and well.i guess some diodes, resistors, transistors, etc. I have a couple parallel port um adapters? i guess you could call it that as well as a db9 adapter to connect to the computer. Okay, so right now i have a PIC16f84 and a couple atmel at90s2313 microcontrollers and was wondering if you guys knew any easy, cheap programmers that i could make given a schematic. 9 Controls Vibration motor 1 10 Controls Vibration motor 2 11 Controls RGB port 2, blue element 12 Controls RGB port 1, blue element 13 Controls Status LED on top side, āLā LED on bottom SDA Controls LED port 2 SCL Controls LED port 1 Analog In Arduino Pin Hummingbird Use 0 Controls LED port 4 1 Sensor 1 input 2 Sensor 2 input 3 Sensor 3 input 4 Sensor 4 input 5 Battery voltage monitor SPI Arduino Pin Hummingbird Use MOSI MOSI to motor/servo controller, can be used for additional modules MISO Not used SCK SCK to motor/servo controller, can be used for additional modules 5.Hello, I'm new to microcontrollers, but am very interested in using them to do many different tasks. ![]() Observe the following tables when mixing top side components with Arduino shields: Digital I/O Arduino Pin Hummingbird Use 0 Not used 1 Not used 2 Controls LED port 2 3 Controls LED port 1 4 Controls RGB port 1, green element 5 Controls RGB port 2, red element 6 Controls RGB port 2, green element 7 Controls RGB port 1, red element 8 Controls SPI slave select for motor/servo controller. ![]() It is good practice to connect only one component to each signal for example, if you have an Arduino shield that makes use of Arduino I/O pin 6, you should not also connect the green element of the tri-color LED on port 2. Mixing top and bottom side connectors It is quite possible to use Arduino shiels and top side connectors simultaneously, but care must be taken to ensure that signals that map to both the top and bottom connectors are appropriately programmed and connected. You can use A5 as a traditional analog input: an external analog signal will safely override the battery voltage signal. Use another analog port if you wish to retain this feature. Battery Voltage Detect: The Hummingbird Duo has an integrated battery voltage monitor that makes use of analog input pin A5. ![]()
