LCD Panels Summary — 7.2%

[...] page is an attempt to summarise and link to the various LCDPANEL drivers available for the various MMBasic platforms. These can be built in (OPTION LCDPANEL xxxx), Cfunction loadable drivers or MMBasic drivers implemented with the OPTION LCDPANEL USER method. The scope includes links to various TBS threads that discuss supporting PCB designs, drivers etc, where to purchase. In general this page will try to link to relevant threads on TBS rather than reproduce the information here. This page initially inspired by @panky's TBS post . TBS [...]

Backpack Tracker curve tracer — 4.0%

[...] When waveforms differ between boards, that points to the culprit. The tool has a memory button, so the waveform of the known good board can be checked more carefully. If there is no "known good" circuit is available, still comparison can be made to similar nodes in the same circuit, and differences will point to the culprit. In example microprocessor pins are all similar, if one pin shows a different impedance, there is reason to doubt the microprocessor as being defect. Creating an impedance graph is based on a very simple principle: apply a voltage to that pin, and measure [...]

_MMBasic Code Library — 1.9%

Welcome to the {NAMESPACE} namespace (zone) of MMBasic is an interpreter for members of the PIC 32MX & 32MZ, STM H7 & L4 micro-controllers, the Raspberry Pi and a DOS version. Principally developed by Geoff Graham for PIC32MX and later Peter Mather's eXtreme version for the PIC32MZ and versions for the STM H7 and L4, you can get it and read all about it here: http://mmbasic.com/ It provides a rich programming interface that harks back to the "feel" of the original (and widespread) MicroSoft Basic languages with definite influence from [...]

Some Hints & Tips for writing efficient code. — 1.7%

[...] aimed at the MicroMite range of micro-controllers but the ideas are fully migrate-able across all the MMBasic platforms and beyond. On the smaller micromites, some tasks can be a big ask for an interpreter at 48MHz (or slower). Some of the following tips got an RC4 encryption algorithm usable - it was struggling to do un-encrypt >> process >> encrypt in under 1.5 seconds. It's still tight for long strings but it's usable now. So these tips can help and even have proved vital in some instances - do not dismiss as mere pedantry too lightly. This isn't an exhaustive list; [...]

Multiple LCD panel displays — 1.5%

MMBasic on the Micromite can natively drive a number of common LCD panel types, these can really bring a spark of panache to a project and are cheaply available on electronics components outlets/tat-bazaars at around the £5 (US$6, AU$8, e6) mark. I have a requirement for such a display but it needs to be long rather than big due to restrictions on the space available. I decided to try stacking two 2.8" colour TFTs side by side, but would it be possible to drive them from a single Micromite? In the breadboard knock-up, I handle the CS pins [...]

Measuring RMS (algorythm) using MMBasic — 1.2%

[...] is a method of implementing RMS measurements on a mains AC signal, with minimal external circuit, in MMBasic on a small micromite. The name RMS (Root Mean Square) explains exactly what is involved: Take the square root of the mean value of all the measured value to the power two. 1/ take samples from an ADC 2/ calculate the square root of each sample and sum them all up. 3/ divide by the number of samples (summing and divide by number is essentially the mean value) 4/ take the square root of the mean value. In essence there is no start and end to this process. But if [...]

Driving LCD with I2C interface using a Micromite (>5.3) — 1.0%

These boards can be picked up for around $1 AUD on a well known and loved auction site. The code is an adaptation of the original Maximite code by John Gerrard. I hope you all find it useful. GTG!

Shape drawing for Complex Lines and Polygons — 0.9%

The MMX and ST variants of MMBasic implement a Polygon command that takes a set of points in two integer arrays and draws an outline of the area with the option to fill the interior. The following is inspired by this command but includes an option to draw the data as either a line or a polygon. There is no option to fill the enclosed area. As written below, the routines use the Cartesian drawing commands (see dependencies) to provide co-ordinate 0,0 in the bottom left of the display. It is an easy enough job to replace the relevant drawing [...]

A Simple GUI pack — 0.9%

A purely MMBasic GUI pack to provide a WindowsCE/95 look-a-like LCD panel interface for your projects. This is a work in progress in my spare time. This document has lots of improvements required - and I'll do them... just need a bit more time. Still to come: Lists, Drop-down Lists, tab strips, pop-up windows (if I can work out a way to do it). As it is now, it provides a lot of functionality and is usable. If you only need the simpler end of the GUI - buttons, checkboxes, radio buttons and text boxes etc, it is good to go. Let's face it; they probably cover 100% of [...]
