Re: FlySky FS-T6 Schematic and Firmware Development

One can use a pre-build cable to flash fw into TS-6, where custom or original.

Re: FlySky FS-T6 Schematic and Firmware Development

I would like to try flashing the original FW back to my transmitter, do I have to flash or erase the eeprom chip? No, no need to erase the eeprom. However, the content of eeprom will be lost as orig vs ART-6 are not compatible. Also does anyone know how to calibrate the sticks in the original FW? I...

Hack it to 8ch?

Does anyone know if the Tx module can be "persuaded" to send all 8ch?

I have recently paired my FST6 an 8ch receiver. However, only first 6ch are getting to the Rx, despite the custom firmware ART6 _is_ generating PPM with 8 channels.

Port to FS-T6?

Are there any reasons for a port for FS-T6 would be hard to do? The FS-T6 hardware is somewhere between 9x and Sky9x board: STM32F100 @ 24MHz 128kB flash 8kB RAM 64kB EEPROM It's a 6 channel Tx w/ 4 switches, LCD similar to 9x. It does _not_ have 4 cursor keys but instead only a Left/Right rotator p...

Re: FlySky FS-T6 Schematic and Firmware Development

Is it 128KiB flash CPU or not? Unfortunately it does not appear so. The CPU on the board is STM32F100R8T6B. This decodes as follows (according to http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/CD00251732.pdf ) STM32F100R8T6B: STM32 - 32 bit arm micro-controller F ...

My first attempt to control a plane (on the ground). Not so successful. There appears to be an interruption in the ppm train about once a second. I did not see this on the scope, need to look closer!

Statically linked call is specific to the board because it uses board specific devices and GPIO pins to generate the ppm. Interfaces are optional.

Re: FlySky FS-T6 Schematic and Firmware Development

Martin, It would be interesting to see if you can flash the original fw this way? Then, to check if the original's fw upgrade method (from system menus) uses this same stm32 bootloader? Btw, it's interesting library! How are you planning to avoid "least common denominator" effect for such a beast? E...

Re: FlySky FS-T6 Schematic and Firmware Development

Potentially, the switches could be added to the ADC read chain, then ADC value stored in a var, and then the ppm/mixer routine would just probe the vars instead for wasting time for ADC conversion?
