Step 4 Getting The Atmega. Microcontroller Ready To be used as a programmer Getting the atemega. Step 1 into the atmega. Note Make sure you burn the right fuse bit configration along with the firmware into atmega. HFUSE0x. C9 LFUSE0x. EFif you have a problem how to burn those fuse bit use the give serial avr programmer then please visit serial avr progammer page for detailed information Step 6 Driver installation on a PC. At the first time when you connect your programmer to the pc your programmer will be dected as usbasp and you have to provide a proper path for drivers to be installed.

Step 6 Programming the other microcontrollers. You can use any of these software to burn the hex file in to the traget microcontrollers. Hardware. Schematic. Connections to the traget microcontroller you can programe many microcontroller by using this schematic, all you need to do is that find out the data sheet of that mcu you want to program and check the pin configration. PIN MOSIMISOSCK and Reset, the connection will be as follows Connectors you may also like 3. Panel Volt Meter Using Pic mcu. Creating a Serial to USB driver using the Android USB Host API Using Android in Industrial Automation. Lately we have received many concerns about using the serial interface on Android Honeycomb with USB Host. The way to usually communicate with a USB Serial device in Linux, is to create a virtual serial interface and use it like a normal serial interface. For instance if you connect an FTDI controller via USB, a device devtty. USBX will be created. USB Serial Connection connects streams to Bulk Endpoints. However, behind the scenes you are actually communicating with the device using plain USB Bulk transfers. This job is done by the USB Serial driver for you ftdisio for instance. If you like to avoid using the kernel driver for some reason you can do this by using a library based on libusb called libftdi. If you look at the source code you will notice that this library manages the connection depending on the chip type to the serial controller. Part of this task for instance is resetting TXRX or setting the baudrate, which is not entirely trivial as it turns out. Reading data is pretty simple if your IN packet returns more than two bytes there is data ready. While when sending data you have to be sure not to write more than the max packet size defined by the controller. For details see the source code of libftdi. Looking at Android there is a core problem with serial devices. As shown in a previous article it is pretty complicated to get started with building the driver. However, the even more painful part is, that there is no API featured way to receive permissions for the devUSBX device node So root is required. But Hey With libftdi, or its implementation it is now possible to write your own driver using the Android USB Host API. Apprenticeship Programs In Atlanta Cosmetology. In the attached example application a connection to a VNC2 Controller is opened and each seconds one byte is transferred. For the example LEDs on the board are toggled. Using the Bulk OUT EP a rs. Download the Android source. Note that you should change the VIDPID String according to your device VVVV PPPP. Also note that if you would like to test if this works on your computer you should first remove the ftdisio driver using sudo rmmod ftdisio. Debugging on your Ubuntu machine Its probably much easier to debug on your workstation. Recently I found pyusb pretty helpful sudo apt get install python usb. Here is a python script that will get you started main.
