I had put together a breadboard version of an Arduino Uno, and the first problem I had was installing the drivers for my CP2102 USB to UART device.
Solution to that problem: I eventually found, downloaded, and installed the driver from here: http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx (http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx)
After that, I was able to get the Blink sketch uploaded and was happy to see that everything seemed to be working. But, something important came up, and I had to put all my hobby stuff away for the day. I came back to it a few days later, and I was about to go insane because I could not upload anything. Kept getting those annoying sync errors.
Solution to that problem: I disconnected my power supply and connected the USB power from the bridge. (I actually had it wired that way when I installed the correct driver, but I didn't know at the time that this was necessary.)
Everything is just dandy now. Uploading sketches is no longer a problem.
So, I'm not so sure what might be wrong with my normal method of providing power to the board, but it turns out that the USB to UART bridge only works when I have my board power coming from the bridge. Anyone know why this is necessary?
Anyone know why this is necessary?
Forgot to connected the grounds?
hello can you post you bread board version ?
i keep getting this
avrdude: stk500_getsync(): not in sync: resp=0x00
might be because of any 1 of the reasons
you may not selected the proper board. i am having arduino uno board. so i will choose (tools->boards->arduino uno).
you may not selected proper serial port. i connected to ( PORT ) com8. so i will select(tools->serial ports->com8).
you might not installed proper driver software. so go to (control panel->device manager->ports) if u can find audrino there install it.
if you found some thing else install the driver software then. i am using a printer cable so it will show like cp210x USB to UART bridge. i used the prev link which cooper shared to download driver for UART.
once this is done. you can connect your board and try .
This actually worked for me as well. :)
Thank you for sharing your knowldge
It worked for me to
