ESP8266 Basic Interpreter Lowers IoT Entry Bar For Amateur Programmers (esp8266basic.com) 112

Posted by timothy from the go-cheap-and-go-home dept.
New submitter mmiscool writes: ESP8266 Basic is a project less than 6 moths old. It is open source and designed specifically for the internet of things. The ESP8266 microcontroller costs less than $3, and once the basic firmware is loaded to the device a user can connect to it using Wi-Fi and start programming right inside their web browser. No wires, no software or plugins to install. Just a simple text editor. There is now a community, primarily older folks who fell in love with Basic on the Commodore, who are using it for controlling a variety of projects. The code is amazingly simple and includes commands for interfacing with neo pixels, OLED displays, Temperature sensors, hobby servo motors and of course the blinky LED. It also provides commands for browser widgets that can be used to construct interfaces for the device like textboxes, buttons, sliders and dropdowns. The bottom line is that Basic is not dead, and has finally made its way into the internet of things. Make last year ran a three-part series on the chip (here's part one), but things have advanced quite a bit since then, when people were first noticing that the ESP8266 is more powerful than the tasks for which it was first marketed.

      Yeah, me too, but remember that C64 BASIC didn't have an else statement, and even the IF statement was somewhat limited, meaning GOTOs everywhere. BASIC is not my choice for programming, even on the C64 anymore (where assembly is actually cleaner, and the assembler can do a good job re-numbering the lines).

      • So weaknesses and constraints on BASIC on the C64 impact it's usefulness today?

        I have a BASIC compiler for the PIC microcontroller that produces tight little binaries. It has a nice useful library of I/o functions.

C64 "V2" Basic was my first taste of programming and I was pretty much hooked straight away, even though it was a fairly unpleasant dialect, with line numbers and no auto-renumbering function, only two significant characters in variable names (so "speed" and "spinning" were the same variable, leading to code with awful variable names) and the lack of any commands for controlling the audio hardware or doing anything with video other than writing characters and symbols.

      That's a valid point. Before you connect a "thing" to the internet, it would be wise to think about what happens when it's hacked. Unless the code is written by someone trained in security and then reviewed by someone else well-trained, it is reasonably likely that it will eventually be hacked. Internet-connected TVs have been hacked, wifi cameras are frequently hacked ...

      In some ways it's unfortunate timing that the internet has become so pervasive at the same time that simple programming has become so easy you can write software without any training or experience. It's resulted in a lot of very bad and dangerous software on the internet.

      I suspect that with BASIC not relying on pointers at all for general function, security for IoT is probably a lot better than when C is used. I don't think your pessimistic comments about BASIC are really valid. Also this BASIC implementation is interpereted, so as long as the interpreter is secure with bounds checking, BASIC programs could well be very secure and correct, much more than many people's C sketches are in Arduino!

      Whose idea was to choose an interpreted language for the extremely slow 8-bit home computers?

      Because fitting a compiler into the tight memory constraints was next to impossible. The BASIC ROM on the C64 was 8 kB; per Wikipedia [wikipedia.org], this is what forced Commodore to revert to v2.0 BASIC, which lacked even disk directory listing commands (remember LOAD "$", 8 and how it would clobber whatever you had in memory?).

      Applesoft BASIC, which had these features, used 10k of ROM by comparison. Apple's earlier Integer BASIC was about the same size, but gave up floating-point support.

      BASIC made it easy for beginners (like myself) to get something working. If Commodore had only included an assembler, for example, this would have been too steep of a learning curve for most folks and they would likely have bought something else that did have an interpreter. That said, anyone writing "real" programs wrote them in assembly; you had to resort to extreme tricks to get decent graphics on these systems. If you haven't seen it, I highly recommend picking up a copy of Racing the Beam [mit.edu], which documents all the trickery that programmers for the Atari 2600 (which had weirder hardware but still was 65xx-based) had to resort to in order to make even halfway decent games.

    Since it hasn't been mentioned here. The ESP8266 is no stranger to interpreted languages. The NodeMCU firmware offers a Lua interpreter. It's been around for longer than this BASIC project and is now fairly robust. I have created a couple of projects with it and been pleasantly surprised, particularly with support for the u8glib library. This is just outstanding.

    There's lots of reasons to like an interpreted language on a device like this. That said, the hardware/libraries integration and maturity is way more important than exactly what interpreted language. I feel a tag nostalgic for BASIC but I don't really see the utility over the excellent NodeMCU firmware. There's even an online firmware builder that allows you to select which features, ostensibly hardware protocols and the like, to bake in so you can maximize how much free heap there is. http://nodemcu-build.com/ [nodemcu-build.com]
