From 5375c6d876f115a2bd75ec45796e5333ba928082 Mon Sep 17 00:00:00 2001 From: Dawsyn Schraiber <32221234+dawsynth@users.noreply.github.com> Date: Fri, 20 Jun 2025 00:10:22 -0400 Subject: Big Kahuna - IREC 2025 - Dawsyn's Final Commit (#16) # Dawsyn's Final Commit This one is a little emotional as this is my final commit in this repository and as a member of Rocketry at Virginia Tech. This merges the changes seen in the branch known as 'big_kahuna' into main. This is the version of the ADS software as seen on [Roadkill](https://drive.google.com/file/d/120BvI-0ntliHo6i9UxcCn2pXAl-JsdP_/view?usp=drive_link) in the 2025 IREC competition. There are bound to be bugs, but I have found it useful to have the final competition version to be the one present on main at the end of every academic year. Hopefully this is useful to the next lead. ## Primary Changes + NEW I2C drivers to support sensors present on new ADS custom PCB + NEW logging library found in separate repository and pulled in as submodule ([pico-logger](https://github.com/rocketryvt/pico-logger)) + No longer dependent on different flash chip from one used for code storage! Compile executable as RP2040 'copy-to-ram' type to increase flash read/write speeds! + NEW fixed-point libraries to allow for increased performance and sensor sampling speeds on RP2040 that lacks FPU + FreeRTOS Simultaneous Multi-processing (SMP) architecture for task handling and easier introduction / testing of new features + Serial monitor / command system with task performance monitoring commands + WORKING Kalman filter that takes altitude from barometer as measurement and z-axis acceleration from IMU as control to generate state vector containing filtered altitude and vertical velocity + NEW CFD equations from the Ben-ogrithm (to replace the Chen-ogrithm) that includes: + Apogee prediction model that takes current drag force, altitude, and vertical velocity + Current Drag Force equation based on current deployment and vertical velocity to use for Apogee Prediction model + Desired Drag force equation based on current altitude and vertical velocity to generate what drag force is needed to reach 10K ft + Deployment percentage equation based on current velocity and desired drag force to map to flap deployment percentage --- include/altimeter.hpp | 31 ------------------------------- 1 file changed, 31 deletions(-) delete mode 100644 include/altimeter.hpp (limited to 'include/altimeter.hpp') diff --git a/include/altimeter.hpp b/include/altimeter.hpp deleted file mode 100644 index bf7effd..0000000 --- a/include/altimeter.hpp +++ /dev/null @@ -1,31 +0,0 @@ -#pragma once - -#include "pico/stdlib.h" -#include "hardware/i2c.h" -#include "hardware/gpio.h" -#include - -class altimeter { - private: - uint8_t altitude_buffer[4]; - uint8_t buffer[4]; - uint8_t addr; - i2c_inst_t* inst; - public: - altimeter(i2c_inst_t* inst, uint8_t addr); - - void initialize(); - - void initialize(float threshold_altitude, uint8_t interrupt_pin, gpio_irq_callback_t callback); - - void set_threshold_altitude(float threshold_altitude, uint8_t interrupt_pin, gpio_irq_callback_t callback); - - void unset_threshold_altitude(uint8_t interrupt_pin); - - float get_altitude_converted(); - - void get_altitude_raw(uint8_t* buffer); - - uint32_t expose_buffer(uint8_t** buffer); -}; - -- cgit v1.2.3
