Good Afternoon everyone,
I'm going to be working soon with C6748 DSP (from Texas Instrument), however, eventually I would like to transmit data wirelessly and I want the closest-to-SDR transciever pick since it is for academic purposes. I want to insert by myself the preamble of the frame with the length that i want, as the sync word, etc. I want students to see what happens if there a bad preamble and no Bit Sync is achieved, what happens if, lets say, sync word is all zeros. As you see, it is highly configurable, and most of transcievers are very configurable but are fixed in some aspects.
I'm kind of new at this, then I would like to know any suggestions about this, If there is any AnalogDevices transciever that could help me.
I was checking ADF7021 and ADF7030-1 which seem really flexible and are quiet close to what I want but not enough. I want to know which which options are the best for this. I want to have all control over frame structure plus carrier sensing capability for layer 2 designing.
Another option is to independently buy modulator/demodulators, ADC, DAC, etc, and implement this on my own but it would requiere lot of time on testing, connecting, caring about circuitry for votages regulations/compensations and looking for most compatible technologies; which is really time consuming. I want to be somewhere between SDR flexibility and SoC facility. What can I pick?
I need a modem that basically limits itself to only transmit what I write in baseband.
I'm taking advices, suggestions, warnings and well wishes.
Thank you so much for your time in advance.
I would suggest the ADF7030-1, which includes a light packet manager in its firmware. There is an option not to use the accompanying packet manager. The host controller would handle all packet processing. The bit stream generated by the host controller can then be passed to the ADF7030-1 for transmission.
Hello! Thanks for your answer. I was checking the chip more in detail in:
Page 28, seems you are right. Looks very configurable.
I wanted to ask your recommendation about any microcontroller to use this chip. Also if is it possible to use it with an Arduino. Maybe students can use this chip with Arduino (or me, if possible).
Thank you so much for your reply and time.
Have a good day
You could check the ADuCM3029 (M3-based MCU) or the ADuCM4050 (M4-based MCU). We have a kit (EVAL-ADF7030-1 EZ-KIT) that uses both the ADF7030-1 and the ADuCM3029. This comes with an evaluation software GUI that lets you transmit and receive packets easily. Also, there are drivers and example codes using the ADuCM3029.
There will no problem if you want to use other MCUs. You could use the example codes to develop your own set of codes.
Thank you. I will take your advice
