Change Log
- Failsafe modification
- The following protocols are supporting failsafe: FrSkyX, Devo, WK2x01, SFHSS, HISKY/HK310 and AFHDS2A
- In Serial mode failsafe is configured on the radio itself.
- In PPM mode and only after the module is up and fully operational, press the bind button for at least 5sec to send the current stick positions as failsafe to the RX.
- Low power selection is authorized by default: OpenTX and ErskyTX will warn if model is set to low power.
Compiled Files
Multiprotocol hex/bin files attached can be used to flash the multi module.
While these files are fully working, it's easy to compile the firmware with your own settings by modifying the configuration file, _Config.h, and following the compile and upload documentation.
The attached files have been compiled with the source from this release using the default settings AETR, telemetry enabled, serial mode enabled and ppm mode enabled using default table.
STM32 Builds (file names beginning with 'multi-stm-')
- All files contain all protocols
- erSkyTx version (files with erskytx in the name) have the
MULTI_STATUSparameter enabled - OpenTx/JumperTX version (files with opentx in the name) have the
MULTI_TELEMETRYparameter enabled - Files with inv in the name have
INVERT_TELEMETRYenabled - this is the default - Files with noinv in the name have
INVERT_TELEMETRYdisabled - Files with ftdidebug in the name have
DEBUG_SERIALenabled and are built for debugging with a USB-to-serial adapter - Files with usbdebug in the name have
DEBUG_SERIALenabled and are built for debugging via the native USB port - All files except the ftdidebug files have support for the native USB port and the bootloader
Choosing the right firmware file:
- Choose erskytx ot opentx to match your radio firmware
- Inverted telemetery is the default (inv in the name) - choose that if you're not sure or don't know
- *debug files are for testing purposes or dumping data from unknown models, not for regular use
For example, for a Jumper JP4IN1, iRangeX IRX4, etc., and a radio running OpenTX or JumperTX you probably want the file named multi-stm-opentx-inv-[version].bin.
Use Flash-Multi to upload the firmware.
Atmega328 Builds (file names beginning with 'multi-avr-')
- Only one RF module and associated protocols have been included in each hex file in order to fit in the Atmega328. For example
multi-avr-txflash-A7105-inv-[version].hexmeans that only protocols using the A7105 RF module are included. - There are no files for the NRF24L01 as there are too many protocols to fit in a single build
- Files with txflash in the name are built with the OptiBoot bootloader for flashing from a transmitter
- Files with usbasp in the name are built without a bootloader for flashing using a USBasp programmer
Use AVRDUDESS to upload the firmware.
OrangeRX Builds (file names beginning with 'multi-OrangeRX-')
- All CYRF6936 based protocols are included
Radio Firmware
To access new protocols and features from er9x/ersky9x/OpenTX, you'll need to upgrade to the latest version available here:
- er9x test builds
- erskyTX test builds along with the Multi.txt file to be placed at the root of the SD card.
- OpenTX for Taranis
- JumperTX for T16 Compiled FW or GitHub for latest version
