Can u recommend a p type & and n type to use? resistors suck up pcb space.
I am using the 16f882, i have the schematic in proteus, a bit crisscrossed as its being prototyped. Once I can define what pins are used for which features I need to optimise the layout based on the pin locations to ease PCB design.
I'll b able to share it in a day or 2 as I get a chance to lay things out.
Thx Mike,
I found a few dual transistor devices that look like a good option.
I am having a little difficulty with the 4 segment CA. Very few with decent luminosity numbers.
Any suggestions on a switching pwr supply chip?
Also for Transient ESD protection on the analog inputs to the PIC. How does a 2.7K resistor sound? I believe the PIC already has clamping diodes built in, not so?
On the matter of PCB desgin, since I am using a shift register, the data is coming out at about 1 Mhz down the serial & clk lines. Can u offer any advice on bypass caps and signal trace lengths/widths, or if a ground plane is required?
