#134275 - Serial Speed and throughput should be considered Responding to: ???'s previous message |
What are the 3 UART channels doing? Diagnostics, Data-in, Data-out?
What are the UART baud rates? High or Low? Are you buffering the data or processing it in to another format. What is your buffer size requirement for each UART? UARTS with Parallel interfaces obviously send data in 8bit chunks but uses 8 data lines + control lines from the micro. Some have deep FIFOs as data buffers. Some of the NXP (Philips) SPI/I2c Bridge UARTs might be interesting if you need to conserve I/O pins.. and through put isn't critical..(as parallel UARTS) http://www.standardics.nxp.com/products/...irda.gpio/ Joe |
