Sense Hat Gyro Accuracy - Raspberry Pi Forums

-

hi!

i'm working on project needing 4 gpio ports, 4 ground , need gyro.

i'm going need decent amount of accuracy gyro found added features on sense hat bonus decided go it.

know how accurate hat gyroscope is? numbers given mean nothing me.

also, research has led me believe hat uses 6 gpio pins leave me plenty motors, how go using these?

help. looking answers know whether unbox , use new sense hat or send , buy more accirate gyro.

again,.

ps first post whoop. forward giving community

ok have first understand gyroscope does. reads rate of angular turn (how fast sensor spinning) if after direction ur facing obtained measuring rate turn multiply time turning. perfect if rate of turn constant in real life things r accelerating angular rate of turn changing read angular rate @ short time intervals (the shorter time more accuracy) @ high rates of 2000/sec still have error , on time error keeps adding become bigger error , refereed gyro drift. if want know facing have use known obsolete orientation achieved using multi sensors (all of have errors) having a fusion filter takes account sensors calculate obsolete orientation, best filter madgwick check out video http://x-io.co.uk/open-source-imu-and-ahrs-algorithms/

there 1 chip know has fusion filter on-board (although lower performing fusion filter) bno05 made bosh, here adafruits breakout board bno05 https://learn.adafruit.com/adafruit-bno ... r/overview

need gpio expansion board able use gpio pind while sense hat connected gpio pins

Valutazione Template - Joomla! Forum - community, help and support

salve, prima di installare joomla, vorrei porvi tre semplici domande: 1) l'ultima versione in italiano di joomla, supporta questo template prodotto da gavik? loro scrivono che non è un semplice template, ma una vera e propria suite, ma vorrei una vostra opinione. qui sono descritte le funzioni della suite. 2) per sfruttare gli elementi che si vedono nella pagina, ad esempio quello in alto sinistra dove scorrono le notizie, occorre installare qualche componente aggiuntivo? 3) futuri upgrade alla piattaforma joomla, potranno inficiare il funzionamento o la compatibilità del template? vi ringrazio anticipatamente della disponibilità. 1) non vedo nulla di particolare se non una miriade di posizioni per blocchi 2) è un modulo se non sbaglio pagamento, ma adesso non ricordo bene 3) no. ti ricordo che devi installare joomla  1.0.12 Board index Joomla!

SD Datastring Convention

-
i wondering if there preferred convention appending data logged?  see standard sd example uses: code: [select] void loop() {   // make string assembling data log:   string datastring = "";   // read 3 sensors , append string:   (int analogpin = 0; analogpin < 3; analogpin++) {     int sensor = analogread(analogpin);     datastring += string(sensor);     if (analogpin < 2) {       datastring += ",";     }   } creating string called datastring, , appending it, have seen in forums string not liked.  around this, code data logging looks this: code: [select] void sdupdate() {   datetime = rtc.now();   unsigned int hour = now.hour();   unsigned int minute = now.minute();   unsigned int second = now.second();   char datastring[100] = "";   char char_current_pay[15] = "";   char char_overall_pay[15] = ""; ...

First use of Arduino Uno : avrdude error on Blink uploading

-
hi all, i bought arduino (or should genuino) starter kit. first test , failing. i have follow religiously first pages , when trying upload blink sketch, uploading fails avrdude error : avrdude: stk500_recv(): programmer not responding. as suggested in other posts, have tried 1) switch latest hourly build of arduino ide 2) switch previous stable version of arduino ide (1.6.09) 3) change usb cable 1 know working fine 4) make same steps on computer (unfortunatelly, of them macos running on macos 10.11.6, not interesting test) 5) press reset before upload, interesting thing : tx led never flashes the full log attached. idea of why happening ? to save people having download log, it's sync error, resp=0x00 every time: code: [select] avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer not responding and he's running 1.6.11 hourly avrdude 6.0.1. ...
