Dear all I have those two emitters, Flysky TH9X and Turnigy 9X, and of course the software ER9X from a couple of years ago, and I’m very happy about how them work, my problem starts when I want to increase the number of channels from 8 to 10, since now, in both emitters I was using the module FS-TM0...

Here you, and whoever have something that could help.
Thanks a lot for your help

Then i can understand that MISO is a bidirectional signal, am i right?

Hi Mike, which IC have you used as buffer?
As we discussed latest days I have this same problem, and simply I whan't to know if you used buffers, or nor or nand gates, just to go directly and not to waste time.
Thanks for all of your help

Finally solved, i was thinking the emitter was broken, but no, was only without program, conclusion, never use parameter -D , allow always to delete before flashing, and better at lower speed, 9600 it's good enough, don't forget to cahnge it on Arduino sketch too.

Thanks a lot for your help.

My answer to MikeB: • Programming pins on the 9X are as usual on Atmel AVR controllers, Mosi, Miso, Rst and Sck, appart of this Vcc and Gnd, the connections on those pins are as follows: • Mosi: Tcut_SW • Miso: AilDR_SW • Sck: Menu button • Rst: his own network, 10 KOhm resistor, and 47uF capacitor ...

Thanks to both by your answers, if i take away the capacitor i get just the opossite as i need, i could place low value resistor in parallel with capacitor and remove the resistor from reset and vcc, i was thinking about to make some kind of modification on that circuitry. looking at to low the baud...

hi Aeroampl, i go to give you a generic answer, yo have pulses from 1100 uSecs. to 1900 uSecs., on each channel every 20 mSecs., once the channel one receives the burst, starts the two, then the three and so on, no channels starts receiving his signal at same time, just one after other, convert the ...

Making some changes, at this moment i can read and write fuses, read and write EEPROM, but i can not read or write firmware, i get an error when i try to write, if i try to read, looks like reading but finally the file is not valid, it's almost empty error after fail to write: avrdude.exe: stk500_pa...

Dear all, first of all i want to say that er9x for me was a geat discovery, makes a transmiter completelly in your hands without the problems of the original device. Once said it i want to explain that i had a problem, during days i was flashing, and reflashing my Taranis, reading, writting and rewr...
