UART1 seems not to work #58

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
We have tried talking to the propellor terminal on UART1 with no luck, using

uart.setup(1, 115200 8, 0, 1)
uart.write(1, "Hello")

Antonio has connected the propeller RX and TX pins to UART0 and managedto talk 
to use PropTerm as a serial console (to be verified)

Martin has made an extenderboard to connect the serial hardware module to 
USART1's TX, RX, CTS,RTS pins without immediate success. The "232" light 
(connected to TX) does not light, whichit should (using the v1.0 serial board, 
where it should normally remain lit).  The stragest thing is that, in this 
configuration, having reset the Mizar and run
 pio.pin.setdir(pio.OUTPUT, pio.PA_6)
 pio.pin.sethigh(pio.PA_6)
to try and light the TX led nothing happens. But when a volt meter is touched 
to UART1's RTS pin, the "232" light comes on for a couple of seconds, then 
flickers off.

With the extender board today UART1 works in both reception and transmission
