I am not good in Microncontroller nor programmg. Only basic.
wish anybody could tell me how to send data in serial from RF module ( transmit and receive) to pic ( 16f877)using c language or any example of flowcode. i have read from the forum about SPI and confuse whether to use master sync port ( MSSP ) or USART for this purpose since i have seen from others using USART for this purpose. Again pleasss help me.
What is the serial / product code fo the RF module. Maybe there will be a datasheet informing exactly how to interface it.
If other people are using the UART then you will probably need to use this also. However you will need to find out if the communictaion method is synchronous or asynchronous (clocked half-duplex / full-duplex).
In the Pic datasheet there is a list of exactly how to program the UART in both synchronous or asynchronous mode.
I am using 433 MHz rf ( transmitter and receiver )at this moment. I am attendint to use tranceiver ( laipac 2.4 Ghz - not buy yet ) for dual communication. I don't know the serial number ( when i bought it small size with no serial number ). I think it usart ( ascynronous serial comm ). I have 2.1 flowcode but it doesn,t have the asyncr serial block. some example using basic which i get from internet( retron) at below web . the program look simple in basic
I have seen this project before and your right the code does look easy. If you use the RS232 component in flowcode then this will utilize the UART pins.
I suggest these ones because they do not need the RS232 serial communication. They are basically an easy way to get 4 digital I/O lines straight to the reciever module. All of the multiplexing is taken care of for you and the devices are encrypted to limit the possibility of data loss / corruption.
U are definately right benj, i have tried use RF encoder before and it's working but i wish to try and learn using serial communcation. I have choose, pick and alter some of the program in c2c( i am also use c2c compiler ) website wher i wish to send and receive binary / data for rf ( were 2 micocontroller involve, one at the transmitter and another one at the receiver )but i don't know whether its working or not. Pls comments. TQ

Ola estou aproveitando este topico para tirar uma dúvida.Eu preciso decodificar controle remoto tx HT6P20B utilizando o pic 16f628a.Esse controle é o mesmo que usam em PORTÃO AUTOMATICO e ALARMES residencial.Gostaria de saber como implementar isso no FLOWCODE

Hi Benj,
I intend to use this DRF7020D27 module (from here: http://www.dorji.com/pro/RF-module/High ... eiver.html) for my wireless data collection which is one master and two slaves, controller used is PIC16F877A. The idea is using polling method.. I do not experience on programing...could you give me some advise?
Sorry for asking for helping on such an old thread, but I would really like to know exactly how we should implement this kind of solution in Flowmotion?
It would be great if I could get 4 wireless IO lines, but It would help to see some sample coding, if possible.
Cheers and thank you for your help!
