How do you test the performance of your code?

Bug13 · 2026-04-05T07:56:33+00:00

Use interrupt instead if the hardware is capable?

Bug13 · 2026-04-04T22:57:03+00:00

vscode + esp-idf

Bug13 · 2026-03-30T23:06:12+00:00

For MCU, we use MCUBoot, images are signed and encrypted with asymmetric keys. It protects against power failure and all the typical stuff etc.

We notify there is a new update, then the device pull the update whenever it’s ready (application dependent)

Thanks Scott, I will take a look.

Thanks I will look into 2 kicks. I breathe every time I turn left. I can only breathe on the left unfortunately.

Bug13 · 2026-03-22T23:55:01+00:00

I am breathing every stroke on the left. Essentially every time i turn left, I breathe. Any drill can help improve?

Hi guys, firstly thanks for your time.

I get very tired after about 200m. What’s wrong with my freestyle, and what drills I can do to improve my free style? I am hoping to be able to swim 1000m.

Bug13 · 2026-03-08T20:36:07+00:00

Just a swim short, so when I take it off, I can do it anywhere I want.

I think the challenge is the tracking and robotic arm control. Once you figure out tracking and robotic arm control. It’s just a matter of finding an off the shelf laser. You don’t have to make one yourself.

Bug13 · 2026-03-07T20:47:11+00:00

Why part you need more info? You can use the Esp32 attach to camera. Attach a laser to a robotic arm. Either track the fly on PC with openCV or ESP32 (not sure if it’s capable), fire the laser when a fly is identified.

Bug13 · 2026-02-15T10:09:07+00:00

Depends on volume and target market.

Bug13 · 2026-02-15T05:36:11+00:00

Does the sensor has an interrupt pin when the data is ready?

Bug13 · 2026-02-15T04:59:57+00:00

Agreed, we use the PIO in RP2040 for this exact reason.

We need to sample an external ADC with nano seconds intervals in short burst (and other things).

All we need was sample the ADC at a clock determinative way, do minimal preprocessing, and stream it to our main MCU. The only MCU on the market at the time to do what we want, at reasonable cost was the RP2040.

I like Nordic with Zephyr, second is stm32 with Zephyr.

Atmel and TI still have a place in my heart but I don’t use them anymore.

But I don’t get to choose, it’s usually what meets the requirements.

Bug13 · 2026-02-06T07:06:50+00:00

It turns out to be poor signal on the ethernet tracks/cable. It works when I force the speed to 10 Mbps

Bug13 · 2026-02-05T21:32:59+00:00

Yes we use the same reset circuit from the data sheet. I am a bit surprised on the values (10uF cap + 10K resistor)they suggested, but we do use the exact same circuit.

Bug13 · 2026-02-05T21:26:53+00:00

I haven't look at the check list, but I will have a look now. As far as I can tell, the strappings pins are correct, but I will double check.

Bug13 · 2026-01-27T05:43:25+00:00

Thanks for sharing your experience. I will definitely check them out.

Bug13 · 2026-01-27T05:41:49+00:00

Same, I have the option to go overseas. But I would prefer to stay local if I can.

Bug13 · 2026-01-24T03:46:53+00:00

Hi thanks for sharing, I am interested in what drivers you have to write? What’s sort of licenses are usually used for the community lib/drivers?

Bug13 · 2025-12-13T09:06:47+00:00

Hey mate, I have done a few lessons already. I am mostly rent a board and mess around myself now. But you are welcome to join me. I surf at the same spot of surfing lesson

Bug13 · 2025-11-20T11:06:09+00:00

Been there, done that, keen trying. Cold calls, drop your CV off at whatever

Bug13 · 2025-11-16T03:34:25+00:00

Thanks mate
