Hi,When sending frames to the radio module, did you have to use a fast external crystal/clock (for example a 16 Mhz crystal) in order to make sure that they are sent precisely every 22 ms? The reason I ask is that I noticed that there's a crystal on the transmitter board which is probably used for this purpose?Chris
Hi,I looked at your source code for flying the helicopter and I would like to double check something with you. First the helicopter is turned on. Then in order to bind to the helicopter, the 'no_thrust' command packet is sent to the radio module every 22 ms for at least 4 seconds and at a baud rate of 133,000. Is that right?
Hi,Thanks for your reply. Is this the source code for controlling the RC helicopter you reverse-engineered or for controlling a Puzzlebox helicopter?
Thank you so much for answering. You saved me $200!
Hi, which of the Saleae logic analyzers would you recommend I buy in order to figure out the signals sent to the radio module? The basic 8 channel logic analyzer ($220): https://www.adafruit.com/products/2512or the 8 channel pro version ($480): https://www.adafruit.com/products/2313The specs for the more basic 8 channel analyzer are:Digital Sample Rate: 100 MS/sCan view digital signals up to 25 MHz1.8-5.5V logic levels (as well as RS-232 and RS-442/3)Whereas the pro version specs are:Digital Sample Rate: 500 MS/sCan view digital signals up to 100 MHz1.2-5.5V logic levels (as well as RS-232 and RS-442/3)
Hi,When you have a chance, could you post the signals sent from the transmitter chip to the radio module for the following situations? -binding-hovering-flying forwardThe reason I ask is that I'd like to see what those signals were for your transmitter and compare them to the signals I'm getting from my transmitter. Just to see if I'm on the right track. Thank you!Chris
