hi guys,
im still new with arduino , thus i have couples of queries regarding serial communication with other devices.
1)will arduino hardware uart able to communicate at 1MBps baud rate rather than 9600?
2)is it possible to change the uart into half duplex asynchronous serial com?
3)which command should i use if i wan to send packet command?
how to change make arduino communicate at 1Mbps?as i read from other website which stated that it can communicate at this speed.
2)how to change serial com to ttl half duplex programatically?
is the rx and tx pin same as those in the usb port?
im back..i was in the ladyada's forum.i somehow got my answers for my previous questions.
someone told me that arduino can communicate with a device at 1Mbps,but i will try out first. Forget about the half duplex issues, i guess that i will use a device that can communicate at ttl full duplex uart with arduirno.BTW it can be done right?
the next problem i might be facing is that a few identical devices will be connected in daisy chain manner to the tx and rc pins.will arduino be able to communicate with those using multi drop full duplex uart serial communication method?
