Hi,
sorry for my late reply.
We did little bit of digging on what we need to do..
1. We will send message from PC to PSOC through hyperterminal-RS232 connection. PSOC has onboard RS232 interface, so no need of MAX232 IC.
We make use of UART or Rx8 user module available in PSOC designer to receive data from PC.
2. The message from PSOC is to be transmitted through a RF transmitter. Here we dont have to modulate. Data we put at RF-transmitter pin is received at the RF-receiver pin. Modulating and de-modulation is taken care by RF Tx and Rx IC.
3. This data from RF-receiver is collected in another PSOC and displayed on LCD.
I am struck in the part where I have to tap in the data from Rx pin in J13 of PSoC and display it on LCD.
For this I have to connect a wire from Rx pin of J13 to any port pin and the port pin is connected to Rx block in PSoC
Im trying the APT(application programming interface) from Rx8 datasheet but i don't get the expected data.
I tried using 'CHAR RX8_cGetChar(void)' and the example code in datasheet but none works for me.
I am not sure if there is data coming out from Rx pin in J13. that pin seems to be high always.
Can anyone help me?
