Dev board
Hi here is the dev board. the ic looks small but the pins are numbered according to the DIL layout
. I just need to add the lcd and 5V regulated psu to the schematic
If there is a need for serial interfacing with a pc a TTL to RS232 converter has to be implemented. Am wating for mine to arrive. There are two ways use a MAx23X ic then a usb to serial adapter
or there are ic's based on CP102 and the like of ic's which can convert from USB to TTl and have drivers to emulate a virtual COM port on a pc.
Am not sure i will build this board but it was just to give it a try but am eager to build a 16F877A dev board with everything above plus micro sd on the SPI lines as well as a VS1053B (beware TQFP48!) and a serial interface.
