Greetings All:
A new
PIC device, the 16F628, has come along as a replacement for that old PIC
workhorse, the 16F84. It is pin and functionaly compatible with the
16F84,
has more memory and its greatest advantage, a built in UART. So now even
simpler serial comms becomes possible in a PIC without tying up the code
just polling or sending RS232 characters. The 16F628 is also cheaper than
the 16F84 !
Yes, this is a wonderful device, I have been using them here for some months
now. There are some limitations on the serial port clocking accuracy with
certrain crystal oscillator selections, the good news is that I have one
working at 19,200 using the internal 4 MHz RC oscillator.
They work especially easily with the G4JNT DDS board...
