  • Any chance of selling just the board without the Nokia LCD? I bought the LCD separate from you guys a few months ago and had no idea how dismally small that little connector was! At the moment, I have no idea how I’m going to connect it to use it.

  • Could anyone that has gotten this to work with an AVR kindly post how you did it? I’ve purchased two transmitters (WRL-08946 434MHz and one receiver (WRL-08950) and I have not been able to get them to communicate. I’ve tried both tx'ers (one at a time) and nothing. I know my USART communication is ok as a) I’ve used this code on several other projects and it’s fine, and b) when i hardwire connect the TX from one ATmega328p to the RX of the other ATmega328p and open my console on the RX end, i can see the communication perfectly. I’ve checked, double checked the wiring and connections. I’ve followed two separate tutorials using these devices.
    Can anyone suggest how to get these working?

  • So here’s YAR (Yet Another Request…you thought I was a pirate, didn’t you?) for being able to purchase just the protoboard without the extra kit. Oh, and maybe paint some flowers on it and partner with Celestial Seasonings to send them out in scented cach?s. I have lots of other great ideas, too! :)
    But seriously, being able to purchase the bare board by itself would be a very awesome thing.

  • Solved!

  • Hi Michelle,
    The EIA-232 chip I use is the ti max232n []. The datasheet has detailed information and seems more designed for implementing a full/partial RS-232-F standard without having a lot of external components to generate RS232 voltages from 3.3 or 5v and then convert them back down to CMOS/TTL levels (along with a few other niceties). As for going from AVR to USB, maybe this could be a start:
    Check out the schematic at the bottom
    Good luck!

  • Has anyone had a problem uploading their hex code to their AVR while PD0/PD1 is connected to pins 12/11 of the max232? I use AVR Studio w/ avrdude to upload via USB from Win Vista to an ATmega328p on an Arduino board with a serial console RS232 to a FreeBSD box connected via the max232.
    When I run avrdude to upload the hex: avrdude -p m328p -c avrisp -P com3 -b 57600 -F -U flash:w:zork.hex avrdude:stk500_getsync(): not in sync: resp=0xff avrdude: stk500_disable(): protocol error, expect 0x14, resp=0xfc</code When I disconnect the RX/TX between the ATmega328p and the max232 it uploads fine. Any suggestions? Thanks!
