[EN] ulab v3.0

By jarutex November 18, 2021

From the previous ulab article, it was found that Micropython can implement the same dataset processing instructions as used in Numpy through the previous ulab library v.0.54.0 which is the older version of ulab (currently v.3.0.1) brought up this article. This article describes how to create a Micropython that integrates the ulab library and uses it with SPIRAM versions of esp32.

From Figure 1, it can be seen that the structure of the ulab library has changed from the original. This causes the programming from the previous example to have to be modified. Under ulab there are libraries of numpy and scipy. The details of numpy that are supported are as follows.

By jarutex August 21, 2021

EP 7 of the ulab library series deals with the approx submodule used for approximation of numbers, function results or find the root of a function using bisect or newton method and trapz determination. In this article, we discuss the roles of each function and how to use them and sample programs as a guideline for further study and application.

[EN] ESP32 : Display of rotation squares with application ulab.

By jarutex August 17, 2021

This article uses the ESP32 to rotate squares using the ulab library and to display the results of the calculations on the ST7735s LCD graphics module as written in the previous article. The example of the program consists of rotating a square in a clockwise direction and rotating multiple squares in opposite directions

By jarutex August 16, 2021

EP 4 of the ulab library is about the linalg submodule used for linear algebra calculations which is applied to solve linear problems. And it is a tool to predict or study the nature of what happens in a linear way. This article discusses the functions of the linalg submodule and some basic usage examples.

For ESP8266’s MicroPython to perform mathematical calculations like using Python’s numpy library, MicroPython with ulab must be installed. You can download firmware for ESP8266 HERE. For normal ESP32 and with additional PSRAM (SPIRAM).

This article is an introduction to ulab and an overview of the libraries within ulab for further application.

[TH] ulab v3.0

By jarutex August 11, 2021

จากบทความ ulab ก่อนหน้านี้จะพบว่า Micropython สามารถใช้งานคำสั่งเกี่ยวกับการประมวลผลชุดข้อมูลเหมือนกับใช้ใน Numpy ได้ผ่านทางไลบรารี ulab ซึ่งก่อนหน้านี้ทีมผู้เขียนใช้งานรุ่น 0.54.0 ซึ่งเก่ากว่ารุ่นปัจจุบัน คือ 3.0.1 ทำให้เกิดบทความนี้ขึ้นมา โดยบทความกล่าวถึงวิธีการสร้าง Micropython ที่ผนวกไลบรารี ulab เข้าไป และใช้งานกับ esp32 รุ่นที่มี SPIRAM

จากภาพที่ 1 จะพบว่า โครงสร้างไลบรารีของ ulab เปลี่ยนแปลงไปจากเดิม ทำให้การเขียนโปรแกรมจากตัวอย่างก่อนหน้านี้ต้องมีการปรับเปลี่ยน ซึ่งภายใต้ ulab จะมีไลบรารีของ numpy และ scipy เข้ามา ซึ่งรายละเอียดของ numpy ที่รองรับเป็นดังนี้
