I have some questions before I make my order: 1. I am not sure is this right way to calculate R&D cost, 160 kEUR / 500=320 EUR. Yes you can get payment for R&D, but I think you should believe that you can sell at least 1000. And you sell that much if prices are about 150 euros less. Because I have add 24% VAT so the total cost is much more than 990 euros to me. Or can I calculate with German VAT if I buy it in EU? 2. And more important question to me, Can that UART console connector use with 31250 baud rate? Is there low level documentation about it somewhere?
The UARTs (UART1, UART2, and UART3 when in UART mode) include the following key features: • 16C750 compatibility • 64-byte FIFO for receiver and 64-byte FIFO for transmitter • Programmable interrupt trigger levels for FIFOs • Baud generation based on programmable divisors N (N = 1...16,384) operating from a fixed functional clock of 48 MHz Oversampling is programmed by software as 16 or 13; thus, the baud rate computation is either: • Baud rate = (functional clock/16)/N • Baud rate = (functional clock/13)/N
