APD ESC and Jeti telemetry #71
Comments
|
Also, I have read some people use an opto isolator, but I'm not sure if it's necessary on the APD F120X. My max load to the ESC is 150 amps and 35V. |
With Beta firmware it is feasible to send also full serial telemetry. Depending on telemetry type, pins varies:
|
- Remove GND and RAW cables from UART and replace with cables from Vin and
GND
- Resistor is on pin TX0, not RX1
- PWM is on pin8 without resistor

… Ok we're getting closer. Does Rx1 need a resistor?

Still no signal but I flashed the card wrong by only uploading the config.h. Will report back! My config.h: #define CONFIG_PWMOUT false #define SENSOR_ID 10 // Sensor Id |
APD F telemetry is PWM -> pin 8. Jeti Ex Bus output -> Tx. Wiring is the same as my prior post. I got the IDE upload working w/ the full library and config.h. I tried this version: Also tried: Jeti radio -> Apps -> Jetibox Emulator = no connection to MX for telemetry. Am I missing something? |
This is the correct protocol for telemetry as RPM signal. Moreover, if you select PROTOCOL_APD_F, then Jeti would go other pins You'll need to enter in debug mode Change line 77 in constants.h to:
Connect arduino GND to programmer GND and arduino pin 12 to programmer Rx Enable DEBUG_PWM in config.h and post output with serial monitor at 115200 Disable DEBUG_PWM and enable DEBUG_PACKET and post output |
The ESC is faulty has to be replaced. I am going to table this project. Thanks for working with me amigo, and helping to push the hobby in a good direction. |
You're welcome |
I have an APD F120X ESC and Jeti radio and ATmega328. I want to decode the telem using PWM over a single wire. Can you help me with this diagram? I'm not sure about 5V and ground lines. Thanks kindly!
