voxl Tmotor f55 esc

[bensusana]

should is use same firmware / params located here :https://docs.modalai.com/modal-esc-v2-manual/
for the tmotor esc?
or you have dedicated procedure for it

Hello Ben,

The Tmotor ESC with ModalAI firmware supports the same protocol as all of our other ESCs. This means you can use voxl-esc tools to test and calibrate the ESC (https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/tree/master/voxl-esc-tools).

The firmware that is already loaded on your Tmotor ESC should be this one : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/firmware/modalai_esc_firmware_tmotor_f55a_pro_ii_4_in_1_revc_24khz_20230214.bin (firmware hash: ba6d193a, which can be checked using voxl-esc-scan.py script (part of voxl-esc package).

The params that we use for this ESC are here : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-params/FPV_RevB/FPV_RevB.xml -- they are tuned for 6S battery, Xing2 2207 1855kV motor with a 5.1x4.1x3 HQ prop.

Have you already interfaced to the ESC using voxl-esc tools or do you need help? Do you have a proper connector for making a serial to USB adapter? Let me know if you need help with next steps. (I am not sure how much experience you already have with our ESCs)

Hi @bensusana

Could you please provide a link to the Tmotor ESC you refer to?

Thanks

Alex Hi,

We tried using the same voxl-esc tools to communicate with the F55A ESC, but could not succeed.

I show that the baud rate is different (2,000,000 and not 250,000 bps),
but using automatic connectivity tool (different bps) did not change the connectivity status.

Do we need to change the baud rate explicitly?

I saw that you have now slpi-uart bridge support.

Can we use it to communicate the ESC from the VOXL2 (via python ver 3 only?)?

Thanks

Erez

[Alex Kushleyev]

Hello @ErezI,

Can you please describe your setup? Specifically, in your first test, how are you connecting to the Tmotor ESC and where are you running voxl-esc tools? (on your PC or VOXL2 ?). Did you make your own cable for UART communication?

./voxl-esc-scan.py command will automatically try all typical baud rates, including 2Mbit and should detect the Tmotor ESC.

Hi Alex,

Using the same system (PC with Ubuntu OS & voxl-esc-tools, connected directly via FTDI 3.3v to the previous ESC V2, Seeker_V1_tmotor_f2203_1500kv_Param_Rev_A) we succeed to connect, control (spin for example), calibrate and update the xml parameters in the ESC.
The differences are the ESC connectors & relevant pins (RX, TX, GND). and the BAUD rate.

The same system connected to the f2203 ESC - works,
while connected to the F55A - fails.

So we know (succeed) how to work and to configure ESCs using your ESC tools.

Using a Wireshark sniffer (USB sniffer) I see transactions (command and response) between the two sides (PC & F55A ESC), but no ESC identified.

Can you send the interface protocol between the two sides, so I can understand the transactions?

Is it possible that we got ESCs without any firmware?
I tried to update the firmware/parameters also - but with a failure.

Thanks,

Erez

Do you have

[Alex Kushleyev]

Do the ESCs make motor sounds when powered on? Should be similar sound as our standard ESCs. If so, then there is ESC firmware loaded.

Can you please share which FTDI adapter you are using?

I can add a debug mode to voxl-esc tools to print out what it is sending and receiving, this may help. I will follow up tomorrow.

There is also C++ code example you can use for basic testing, i will share that shortly.

Alex,

We use FTDI C232HD-DDHSP-0 & TTL-232RG-vsw3v3-we

Thanks

Hello @ErezI ,

I have added a debug functionality to a new feature branch which i have been working on. https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/tree/add-new-params . This branch has some changes to support upcoming ESC param updates, but it is also functional to test the ESCs (except reading and writing params - don't try it ). We can use it to help debug your issue.

You can checkout the code from the add-new-params branch and try the following test with your Tmotor ESC. You will see that the ESCs are queried twice, but that is ok, it is part of the procedure (kind of redundant, but it's fine ).

Each data packet (outgoing and incoming starts with a header 0xAF) and ends with a two-byte checksum.

In my case i am using a STLInk-V3 dongle as a serial to USB adapter.

Additionally, there is an open source implementation of the basic communication protocol here : https://gitlab.com/voxl-public/support/esc-driver . I am able to use it to query the Tmotor ESC:

Another thing i can think of.. Maybe FTDI chip latency is too high, you can try to reduce it to 1ms with the following command (for appropriate device, such as ttyUSB0:

echo 1 > /sys/bus/usb-serial/devices/ttyUSB0/latency_timer

Please try these out and let me know your results!

@mzahana , we have a limited availability of Tmotor ESC with ModalAI firmware. It is officially not supported. We are working on our own version of a 6S Racing ESC, but it is not yet ready for release. If you can describe your application, perhaps one of our existing official ESCs could work for you.

[ErezI]

@Alex-Kushleyev
Alex

Thanks for your fast & helpful support..
The motors sound like 3-4 successive rings when powered on.

Erez

[Alex Kushleyev]

@ErezI , OK that means the firmware is loaded. All of our ESCs come programmed and tested before shipping.

Alex

Hi Alex,

I am working with Erez ad Ben on this project and it seems that we are hitting a wall which I assume that you are the only one who can help.
I would appreciate if we will be able to contact you directly in regards to the issue in hand, I don't know if this is a setup issue, wiring issue, FTDI issue or etc - but I do hope that in a quick conference chat we will be able to overcome this.

I would appreciate if you will be able to contact me through my E-mail Yariv.l@pearls.org.il to schedule a quick chat to resolve this whole issue.

Appreciate your help and support,

Yariv
