Hi everyone. I am a newbie with AVR (and also RF like my name says). So far I have been used to using the STK500 board to communicate with an RF module via SPI. I'm on my way to make my own custom PCBs to be a transmitter and a receiver. I have some questions that I couldn't find the answer. Hope you could help. Please excuse me for my English and feel free to ask if I'm not clear at any point.
1. I will use JTAG ICE 3 to program my Microcontroller (uC) via SPI (ISP 6 pin). As I have seen in layouts of some Protoboard like this https://www.olimex.com/Products/... , the only connections from the uC we need to make are Vcc, Avcc, GND and the ISP 6pin interface for programming with SPI. Is that all that we need to program with JTAG ICE 3 programmer? (including changing fuses and clocks of the uC).
2. The uC also communicates with my RF module via SPI. When working with the STK500 board, I have seen no difference between unplugging the module or not before programming the uC. However, I just ask for experience. Will the two communication stack with each other? I mean when programming the uC on my custom board, will there be problem with my RF module, because in my board, I have no option to unplug it before transferring the code to the uC.
3. Do you recommend any tutorial/ guide/ reading on building the custom board like in my case? Or suggest me any keywords, because I couldn't find much about this question. Even I don't know how to call the board, but have to use the word "custom PCB using AVR".
These will be my first hardware that I make myself. I greatly appreciate your help. Thank you :D
