MSP430G2553: Launchpad working with simple ASK RF modules.

Part Number: MSP430G2553
Other Parts Discussed in Thread: CC1101, CC1120

Hi All, I hope this is the right section for this and if not please advise and i will correct. Basically I'm trying to implement those dirt cheap ASK (OOK) 433MHz modules with 2 launchpads. I had envisioned a whole mesh network with multiple MSP's, Sensors and RF links feeding back to a base, but as i had been told by numerous people and have also slowly realized myself it really isn't practical with these links so will be ordering some cc1101's but until they come i would at least like to get some use out of these even in a basic way. If not familiar with these links ( Pictured below hopefully) basically the data pin on the receiver goes high whenever a voltage is applied to the data pin on the transmitter that's literally as far as i can get with them, writing a 1 out to a port pin on the transmitter and watching for the result in an ADC on the receiver has yielded little success given the amount of interference on this frequency and my limited coding abilities. I want to send the result of an ADC from an LDR over to another launchpad and print the data on an LCD, I'm well able (may eat those words later) to do the ADC and once the data is in a variable to print to the LCD but getting the data into an appropriate format sending it, receiving it hopefully with a bit of error correction and having it as a variable, is all way beyond me. Ive seen similar implemented on arduino mainly with the virtual-wire library but also without. I really hope someone can help and if this post gets seen by someone else in my position definitely start with cc1101 transceivers UART is far handier, have used with Bluetooth on multiple occasions with good success. owh probably worth mentioning i'm using IAR  thanks again guys any questions feel free to comment or message me

  • Hello Garrett,

    I think you will find the discussion about ASK receivers in the following thread to be quite interesting and hopefully helpful.

    Also, the CC1120 offers better sensitivity  than the CC1101 but has less than half the data rate. After you receive your CC1101's and if you have questions about them, feel free to post them in our Sub-1 GHz - Proprietary and 15.4 Star networks Forum here on E2E.

    Unfortunately, I do not have any experience with these ASK receivers, but I'm sure that many of our community members have and may want to chime in.

    Regards,
