Maximum I2C Clock Frequency
-
Sorry both for the delay, I've been out of office over easter.
@Eric-Katzfey We've tried the magnetometer + magnetometer library with 1MHz I2C on a teensy, so at least the non-voxl2 mini components should support it. Yes you're correct, about the pins. I'll take a look at the dmesg outputs tomorrow and get back to you.
@Alex-Kushleyev I'll try this as well: 1) starting driver at 1M w/out sensor to see driver starts and reports device not found, 2) starting driver manually during runtime and see status output.
Thanks for the support!

I set the I2C frequency to
static constexpr uint32_t I2C_SPEED = 1000 * 1000; // 400 kHz I2C serial interfaceand flash the voxl2-mini. I then manually start px4 byvoxl-px4 -dand wait until all is started. I then started the magnetometer driver byqshell tmag5273 start -X -b 1which causes the px4 session to start printing a lot of messages and stop responding to things like ctrl+c:pxh> qshell tmag5273 start -X -b 1 INFO [qshell] Send cmd: 'tmag5273 start -X -b 1' INFO [muorb] SLPI: Marking DeviceNode(qshell_req) as advertised in process_remote_topic INFO [muorb] SLPI: qshell gotten: tmag5273 start -X -b 1 INFO [muorb] SLPI: arg0 = 'tmag5273' INFO [muorb] SLPI: arg1 = 'start' INFO [muorb] SLPI: arg2 = '-X' INFO [muorb] SLPI: arg3 = '-b' INFO [muorb] SLPI: arg4 = '1' INFO [muorb] SLPI: *** I2C Device ID 0xd3509 865545 INFO [muorb] SLPI: Too many arming check events (1, 14 > 14).

Hi again,
If it's of any help, the repo we're developing this on is: https://github.com/ntnu-arl/modalai-px4-firmware/tree/dev/tmag5273
There isn't really much going on aside from blending a sparkfun library into the ist8310 impl used as a px4 driver template.
-
@Morten-Nissov Yes, that means the DSP running PX4 crashed
-
@Morten-Nissov This line doesn't look good:
ScheduleDelayed(1_us);That's too fast -
@Eric-Katzfey I saw the shedule delayed call in the driver we used as template (with a different number), do you have a recommendation for what a lower bound should be?
We intentionally set it very low to gauge whether the I2C communication was limiting our update rate in the 400kHz case, which it was.
-
@Eric-Katzfey Hi again,
The same happens setting ScheduleDelayed to 20ms (even as high as 100ms). So I guess we're never getting to this point in the code before crashing.
Edit: The driver manages to run
if (!strcmp(verb, "start")) { return ThisDriver::module_start(cli, iterator); }however it never manages to enter
void TMAG5273::RunImpl(). It seems like the crash happens atint ret = I2C::init();inTMAG5273::init(). Using print statements I can see it never manages to execute any line which requires using I2C (e.g. reading a register for probing), which would seem to make sense is I2C never manages to startup.Edit2: As per @Alex-Kushleyev message, I can also manage to change the barometer rate to 1MHz and it starts successfully:

As before it doesn't manage to get past
int ret = I2C::init();. -
I am not sure exactly what the issue is with 1Mbit i2c rate, but i see another way how you can speed up your reads. Currently the code reads each of the 3 axes separately (X, Y and Z) and each axis is using two separate i2c calls to read the value (LSB and MSB). For each single byte read, it actually takes about 3 bytes (time-wise) because the first byte is the slave address, second byte is the address of register to read and 3rd byte is actual value sent by the sensor.
All the result registers are stored one after another, specifically designed to be read in a single batch : https://github.com/ntnu-arl/modalai-px4-firmware/blob/dev/tmag5273/src/drivers/magnetometer/tmag5273/TI_TMAG5273_registers.hpp#L187 . So you should change your code to make a single read to read all of the result registers, and if you use the current 400khz, you will get at least 3x speedup, at least in the reading part. Then you have to make sure the sensor has completed the conversion, or whatever is steps are needed for the sensor update cycle.

@Alex-Kushleyev Sorry if this is a stupid question, for reading more than one byte with the px4 I2C implementation we do this by calling
transfer(&cmd, 1, &buffer, num_read);with the appropriate number fornum_read, or is there more to do? -
Yes you can read more than 1 byte at a time by setting num_read accordingly and making sure the buffer for holding the incoming data is large enough. You would need to set the read address to the start address where you want to start reading the data array.
Then you will need to parse the data out of the returned array into x, y, z axes (and temperature if you are reading that).
-
@Alex-Kushleyev Sorry didn't see the message, but ended up getting the same place. Implemented a read multiple registers which seems to work:
void TMAG5273::RegisterReadMultiple(Register reg, uint8_t* buffer, uint8_t bytes) { const uint8_t cmd = static_cast<uint8_t>(reg); transfer(&cmd, 1, buffer, bytes); }This turned out to be significantly faster (~4x I think), so even without 1MHz I think it could be sufficient for us. Thanks for the help!
-
@Morten-Nissov , great! You are welcome. Make sure to change that 1us scheduling interval to a more reasonable value
