Part five was kind of an intermezzo, where we measured the noise levels and had a look at the DSP capabilities (link below).It’s time to make the first steps towards linearization. We’ll start with the algorithm enable flags, and use one to set the direction of rotation. Then we’ll set the linearization offset to achieve a proper zero point for our angle measurements.00:00 Intro – let’s set the pre-linearization rotation and offset01:24 Algorithm enable – flags to control the digital signal processing07:12 Algorithm enable code – partial extended write, writing flags12:32 Linearization offset – a 16-bit unsigned integer to set zero degrees13:36 Linearization offset code – writing it as unsigned integer or float17:12 Test sketch – setting rotation direction and zero offset20:45 Test results – correct rotation direction and zero point25:34 Wrap-up – next up is the linearization itself, byeTutorials youtube.com/playlist?list=PLwq-2MnM58FKn3920rc1V0qoTsQDheTIwAllegro A1335 Hall Effect Angle Sensor, I2C and Arduino – The Basics youtu.be/b_1zqg0UZw0Allegro A1335 Hall Effect Angle Sensor, I2C and Arduino – The Details (1) youtu.be/Y7G-xwPNqxIAllegro A1335 Hall Effect Angle Sensor, I2C and Arduino – The Details (2) youtu.be/N613LV-wd1gAllegro A1335 Hall Effect Angle Sensor, I2C and Arduino – The Details (3) youtu.be/AmaoXhydWIkAllegro A1335 Hall Effect Angle Sensor, I2C and Arduino – The Details (4) youtu.be/RllH7C1EnKMAllegro A1335 Hall Effect Angle Sensor, I2C and Arduino – The Details (5) youtu.be/n1ULQ1GVoOcMy code drive.google.com/drive/folders/1nyOgEx7O63L0VR9HXH0s6KQf1XFeXoJn?usp=sharing#halleffect #angle #rotary #sensor #arduino #microcontroller #tutorials #tutorial #how-to #robertssmorgasbord

The question is, how will you handle having not only the two hardware serial ports you knew all your life, but four.00:00 Intro – there’s a dark secret01:33 Credits – go all to Kevin01:53 ATmega4809 USARTs – there are four of them02:55 pins_arduino.h – for the Nano Every modified06:11 Test – four hardware serials daisy chained09:06 Words of advice – beware of updates, things might break09:37 Wrap-up – Tutorials youtube.com/playlist?list=PLwq-2MnM58FKn3920rc1V0qoTsQDheTIwRS-422 Differential Signaling (Renesas ISL8490, Arduino MCU) – The Basics (1/2) youtu.be/6YWZMRe-7DQRS-422 Differential Signaling (Renesas ISL8490, Arduino MCU) – The Basics (2/2) youtu.be/hoZ4D2Tk9QcKevin’s Blog: Arduino Nano Every Serial Ports emalliab.wordpress.com/2021/12/16/arduino-nano-every-serial-portsMy code drive.google.com/drive/folders/1bakcJHh_p33_SQiVrDbFZ16A-MGAT9oj?usp=sharing#arduino #arduinonano #serial #uart #atmega #microcontroller #tutorials #tutorial #how-to #robertssmorgasbord

QST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Details (5) Roberts Smorgasbord 2022-04-17 | Noise avoidance and reduction, correlated noise, circular median …↓↓↓ Complete description, time index and links below ↓↓↓In part 4 (link below) we finally managed to nicely calibrate the QMC5883L. We did that by using the matrix method with a bias vector and a scale matrix. But our compass heading was fluctuating quite a bit. It’s time to take care of that noise.We start by trying to avoid that noise in the first place by checking some causes for noise. Then we’ll come up with an effective noise reduction by filtering our azimuth signal. We’ll end up with a fancy moving median filter / circular median.00:00 Intro – it’s time to take care of the noise00:24 Noise – what we’re dealing with03:00 Noise avoidance – avoid it if possible03:07 External noise sources – remove them04:42 Full scale range – use the smallest possible06:39 Oversampling rate – use the highest possible07:22 Power supply – more decoupling is better08:41 Avoidance summary – we did the usual stuff09:47 Noise reduction – filtering, but what and how?12:36 Noise levels – raw, calibrated and azimuth data14:25 Correlated noise – noise that’s not random18:24 Filter traits – modified mean, mean and median22:05 Sample number – how many samples we need25:35 Circular median – no such thing, but we do one23:12 Filtering algorithm – circular buffer, quick sort27:31 Eighth version – median filtering the azimuth33:20 Median azimuth – within 1° to 1.5°, but darn slow36:58 Wrap-Up – I intended it as light entertainment, byeTutorials youtube.com/playlist?list=PLwq-2MnM58FKn3920rc1V0qoTsQDheTIwQST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Details (1) youtu.be/NTDS2Vmnr-4QST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Details (2) youtu.be/sFOK9C-F5XEQST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Details (3) youtu.be/O3ZtVkj6CvUQST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Details (4) youtu.be/RJovRafwgo8QST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Basics youtu.be/xh_KCkds038RS-422 Differential Signaling (Renesas ISL8490, Arduino MCU) – The Basics (1/2) youtu.be/6YWZMRe-7DQArduino, Thermocouples, MAX6675 and SPI – The Fine Points youtu.be/qub3yzqEwekMy code drive.google.com/drive/folders/1y7iLE6iLOgLGdJsME15Qd_4JDpWa1o1Q?usp=sharing#arduino #compass #magnetometer #i2c #microcontroller #tutorials #tutorial #how-to #robertssmorgasbord

We also calculated the azimuth, respectively, compass direction. However, the results of that calibration were underwhelming.So this time we’ll calibrate using the full blown matrix method. That is instead of just using 3 scales we’ll calculate a 3x3 scale matrix. Spoiler: We’ll get much better results.. And we’ll fix those I2C errors we encountered in part 2 (link below) too.00:00 Intro – “scaled biases” calibration was not good enough00:57 Correction matrix revisited – doable methods are available02:06 Calibration data collected – 360° rotations in 14 orientations06:15 Biases and scales calculated – with a free windows program10:17 Seventh version – bias vector plus scale matrix corrections12:12 Calibrated data – almost perfect, azimuth still a bit off15:27 I2C errors – don’t take everything in datasheets at face value20:52 Wrap-up – let’s end on this positive note, next up is noise, byeTutorials youtube.com/playlist?list=PLwq-2MnM58FKn3920rc1V0qoTsQDheTIwQST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Details (1) youtu.be/NTDS2Vmnr-4QST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Details (2) youtu.be/sFOK9C-F5XEQST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Details (3) youtu.be/O3ZtVkj6CvUQST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Details (5) youtu.be/pfMf-4S9yzkQST QMC5883L 3-Axis Digital Compass and Arduino MCU – The Basics youtu.be/xh_KCkds038My code drive.google.com/drive/folders/1y7iLE6iLOgLGdJsME15Qd_4JDpWa1o1Q?usp=sharingSailboat Instruments: Improved magnetometer calibration (Part 1) http://sailboatinstruments.blogspot.com/2011/08/improved-magnetometer-calibration.htmlSailboat Instruments: Improved magnetometer calibration (Part 2) http://sailboatinstruments.blogspot.com/2011/09/improved-magnetometer-calibration-part.htmlDownload Magneto v1.2 sites.google.com/view/sailboatinstruments1NXP/Freescale AN4246 Calibrating an eCompass in the Presence of Hard- and Soft-Iron Interference nxp.com/docs/en/application-note/AN4246.pdf#arduino #compass #magnetometer #i2c #microcontroller #tutorials #tutorial #how-to #robertssmorgasbord

FTDI FT232RL USB to Serial Module (AZ-Delivery) Detailed Review Roberts Smorgasbord 2022-02-06 | A usable USB to serial converter with a nice form factor, put not perfect …↓↓↓ Complete description, time index and links below ↓↓↓A while ago I featured those AZ-Delivery FT232RL USB to serial converter modules in a mailbag (link below). I was high time to put them through the paces.The good news: They’re cheap, have a lot of features, and I like their form factor for breadboard use. However, they don’t quite behave like FTDI FT232Rs (EEPROM not writable), and they lack a poly-fuse as well as a recommended ferrite bead.00:00 Intro – a closer look at that USB to serial module00:19 Chip – FT232-AZ, an FTDI FT232RL made for AZ-Delivery00:47 Board – everything there is, and it’s not much02:45 Pin headers – solder in your own for breadboard usage03:09 Pinout and specifications – as well as a hint at an EEPROM07:03 FTDI FT_Prog – can read EEPROM, but cannot write it10:08 Timing and signal levels – of the USB power management12:31 USB shield – connected to ground12:47 Real word test – with an serial U-Blox GPS module13:40 Summary – the good and the bad16:24 Wrap-up –nice for breadboard use, byeReviews youtube.com/playlist?list=PLwq-2MnM58FIJjuha_h96kWhQR9aSmeANMailbag: Teensy 4.0 600MHz ARM MCU, FT232RL USB to Serial (incl.
