Hi, I've seen in an atmel Basic implementation (and I've tried - it works) a feature which may help amforth with the required delay during the flashing the new word - to use CTS signal. The routine which flashes the flash with a new compiled word shall simply at very beginning put the CTS signal to LOW and when finished put back to HIGH. The LOW on CTS tells the PC side not to send data. So no delays needs to be set in terminal. As the most of users use FTDI USB-RS232: one pin of atmega (defined as output) shall be connected to CTS. The DTR<->DSR at atmega side connected together. Pito |
