<p class="MsoNormal">It takes from the original concept of ESPbasic - which I cooperated on and contributed to in the past - but is a completely re-designed breakaway project designed to offer improved functionality and reliability.</p> <p class="MsoNormal">The intention was to create a Basic language for the ESP which complies as much as possible with the original GWbasic / Visual Basic - from which it shares many concepts / ideas / syntax - and also from the excellent project "Micromite" of Geoff Graham.</p> <p class="MsoNormal">The base of the interpreter comes from the original project "MiniBasic" by Malcom Mclean.</p> <p class="MsoNormal">The text editor comes from the original project "EditArea" by Christophe Dolivet.</p> <p class="MsoNormal">Functionalities:</p> <p

to the esp local disk filing system (SPIFFS).</p> <p class="MsoNormal">In order to use less RAM, the user script is copied from the disk into a dedicated area in the flash memory where it is executed, so only the list of the program lines, the branch labels and the list of the user defined subroutines get loaded into memory.</p> <p class="MsoNormal">This is slower compared to other approaches, but permits maximum memory to be available for user variables and program use.</p> <p class="MsoNormal">Another performance consideration is that the ESP8266 must be capable of executing several activities in the background (web server, file server, ..) so needs sufficient free memory for running such tasks, and those parallel tasks must obviously have an impact on script performance..</p> <p class="MsoNormal">So performance-wise, the interpreter is not particularly fast, but it should be fast enough for most tasks you may require. I tried to run some "1980s BASIC benchmark" taken from "the back shed" forum and I can say that the performance is around 2 to 4 times slower than a micromite @48 Mhz; but (IMHO) that’s not bad considering all the additional connectivity and web functionalities provided by the esp module.</p> <p class="MsoNormal"> </p> <p class="MsoNormal"><b>Basic program lines :</b></p> <p class="MsoNormal">A typical script line should comply with the following syntax :</p> <p class="MsoNormal"><b><span style= 'font-size:10.0pt;line-height:115%;

But contrary to traditional filesystems, the slash character '/' is allowed in filenames, so the functions that deal with directory listing (e.g. FILE.DIR$("/website")) basically just filter the filenames and keep the ones that start with the requested prefix (/website/). Practically speaking, that makes little difference though.</p> <p class="MsoNormal" style= 'margin-top:0cm;margin-right:0cm;margin-bottom:10.0pt; margin-left:36.0pt;text-align:justify;text-indent:-18.0pt;background:#FCFCFC'> -<span style= 'font:7.0pt "Times New Roman"'> </span> Second, there is a limit of 31 chars in total for filenames.</p> <p class="MsoNormal" style= 'margin-top:0cm;margin-right:0cm;margin-bottom:10.0pt; margin-left:36.0pt;text-align:justify;text-indent:-18.0pt;background:#FCFCFC'> -<span style= 'font:7.0pt "Times New Roman"'> </span> Combined, that means it is advised to keep file names short and not use deeply nested directories, as the full path of each file (including directories, '/' characters, base name, dot and extension) has to be 31 chars at a maximum. For example, the filename /website/images/bird_thumbnail.jpg is 34 chars and will cause some problems if used, for example in FILE.EXISTS() or in case another file starts with the same first 31 characters.</p> <p class="MsoNormal" style= 'margin-bottom:10.0pt;text-align:justify;background: #FCFCFC'> <b>Warning</b>: That limit is easily reached and if ignored, problems might go unnoticed because no error message will appear at runtime.</p> <p class="MsoNormal" style='text-align:justify'>All the file related functions share the same prefix <b><span style= 'font-size:12.0pt;line-height:115%;

(ref <a href= "https://en.wikipedia.org/wiki/PID_controller"><span style= 'color:#1155CC'>wikipedia</span></a>)</p> <p class="MsoNormal">A PID controller continuously calculates an error value e(t) as the difference between a desired setpoint (SP) and a measured process variable (PV) and applies a correction based on proportional, integral, and derivative terms (denoted P, I, and D respectively), hence the name.</p> <p class="MsoNormal">In practical terms it automatically applies accurate and responsive correction to a control function.</p> <p class="MsoNormal">An everyday example is the cruise control on a car, where ascending a hill would lower speed if only constant engine power is applied. The controller's PID algorithm restores the measured speed to the desired speed with minimal delay and overshoot, by increasing the power output of the engine.</p> <p class="MsoNormal">Annex implements 4 PID controllers that can be used simultaneously for any application.</p> <p class="MsoNormal"> </p> <p class="MsoNormal">The commands are :</p> <p class="MsoNormal" style= 'margin-top:0cm;margin-right:4.0pt;margin-bottom:0cm;

</p> <h4><a name="_5b6tfp3n9ste"></a>I2C BUS</h4> <p class="MsoNormal">The I²C bus allows the module to connect to I²C devices.</p> <p class="MsoNormal"> </p> <p class="MsoNormal">I²C uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL), pulled up with resistors (typically 4.7K to 10K).</p> <p class="MsoNormal"> </p> <p class="MsoNormal">The I²C has a 7 bit address space permitting, theoretically, to connect up to 126 I/O devices.</p> <p class="MsoNormal"> </p> <p class="MsoNormal">The maximal number of nodes is limited by the address space and also by the total bus capacitance of 400 pF, which restricts practical communication distances to a few meters. The relatively high impedance and low noise immunity requires a common ground potential, which again restricts practical use to communication within the same PC board or small system of boards.</p> <p class="MsoNormal"> </p> <p class="MsoNormal">The current implementation is master mode @ 100Khz by default.</p> <p class="MsoNormal"> </p> <p class="MsoNormal">The SDA and SCL pins can be freely
