I’ve made two simple 433Mhz (EB063 on port C) flowcharts.
Both programmers are Multiprogrammers with a 16F877A.
I’ve looked into the RF macro’s and made these flowcharts in a way I think they should work.
The TX looks like it sends a byte every second, the RX receives something according to the acknowledge. But when I read the acknowledge it returns 254.
This means (according to the help file in V5) that it receives only the length of the data.
“A return value of 254 indicates that the length byte was received but no data.”
Can anyone look into these flowcharts and tell me what I’m doing wrong?
I just have to know the right order for the macro’s to read and send data for these e-blocks.
I have put the programmers a few meters from each other to make sure they don’t disturb each other with a to strong signal.
Any suggestion is welcome..

Hi MJU,
You might find this old post of mine interesting, it uses a 433 mhz tranceiver ....

In this thread: http://www.matrixmultimedia.com/mmforum ... 063#p47368 I found a Flowchart that works.
My problem seems to be in the Timeouts for the receive macro...
How do I set a timeout that works?
I send every second a byte to the receiver and show it on the LCD.
Does the time out has to be longer or shorter than the frequency the sender sends its bytes?
