#189651 - O.K. so what have you learned? Responding to: ???'s previous message |
First of all, you're convinced that the two RF modules do function properly, is that right? Which LED is it that's not glowing? Have you tried examining the signals with an oscilloscope? Have you got access to a logic analyzer? How about a pulse detector?
Have you compared the signal from the PC to the RF module with that from the MCU to the RF module? How about that from the RF module to the PC, and from the RF module to the MCU? Have you made any effort to ensure that the MCU understands the format and frequency of the demodulated signal from the RF module? Does the signal from the RF module adhere to that format? Is that signal truncated at either end? RE |

| do you suppose it could be a timing issue? | 01/01/70 00:00 | |
| i don't think there is any timing issue. | 01/01/70 00:00 | |
| maybe it's the timing generated by that USB-to-serial module | 01/01/70 00:00 | |
