im using a arduino pro mini, and i have a usb to rs-232 cable that runs on 5V. its an HL-340 from ebay, used it before, works great.
i downloaded the arduino IDE for windows, and it does not seem to be using the serial cable, it keeps giving me errors for boards i dont have connected ,i.e. usbasp errors, avrisp errors, ect.
i have the IDE set on com 3, and i did install the drivers.
i have tx,rx and gnd from the serial cable connected to the board. switching made no difference.
i also tried to find a pinout for the mini pro that shows how to upload the bootloader using the MISO, MOSI, SCK, /RESET, GND, VCC bu could not locate this.
ive been using attiyn 25 and AVR ASM for a long time, but this has got me frustrated.
any help?
