spi to uart converter
A micro controller only has one UART port. Therefore, we decide to use microcontroller SPI port as another UART2.
We need a SPI to UART converter (such as MAXIM3100 or NXP - 161S752), however, this IC only supports SPI slave mode only. When we use it with this configuration:
a) Micro controller’s SPI (master) ------ “SPI (slave) to UART”-- PC’s UART
• The communication is allowed.
b) PC’s UART ----- “UART to SPI(slave)” -- Micro controller’s SPI (master)
• The communication is not allowed as slave is unable to initiate talk with master.
May I know any SPI to UART converter IC can support Master SPI? Or do you all have other solution, thank you!
