USART and JTAG, two initialisms that keep showing up in conjunction with Atmega programming. What do they have to do with programming?
Are there pins on an atmega-168 that correspond to JTAG or USART ?
Does one group (USART) correspond to ISP?
Does the other group (JTAG) correspond to programming via USB to MISO, MOSI, SCK, etc ? Or is it the other way around ? Do those pins go with USART
When I program my arduino using an FTDI USB to TTL conversion device, which uses a FT232RL chip, the device is connected to TX, RX, RST(GRN) [reset output triggered by the DTR line] on the atmega, then other end of the cable connects to USB port. Is that considered JTAG, or USART or what? :-? :-[
Things get a little confusing with all of those initialisms tossed around. :o
