Duinomite MINI, MEGA and eMEGA back in stock

DuinoMite-Mega

Duinomite-MINI, MEGA, eMEGA boards were made specially to run BASIC on PIC32 processors, but are well packed with features boards, so people were using them not only with BASIC interpreter but also programming them in C.

There were not high runners, so at one point we were selling just few per month and when the blank boards were out of stock we had hesitated if to run them again or not, with the time lot of people signed for notification when back in stock so we decided to run small batch of all these three and re-stock.

Now we got them back in stock.

Embedded World giveaway board update! Processor will have 2MB Flash, 512KB RAM and 2x CAN

pic32

After our blogging about the Embedded World giveaway board, there was short discussion / comments after the post that it would be great the PIC32 on the board to have more RAM and CAN and do you know what?

Microchip is reading this blog too 🙂 as today we got message that they decided to upgrade the processor for this board to PIC32MZ2048EFH064-I/PT which is with 2MB of Flash, 512KB of RAM and dual CAN!

Now you should have got idea why this company is expanding and grow so fast – they are flexible and their managers obviously have freedom to take prompt decision!

It took them less than 24 hours to react and change the processor on board so you guys will benefit from PIC32 which beside Ethernet also have dual CAN and x4 times more RAM and FLASH than what originally was planned!

New Product in stock: PIC32-RetroBSD Open Source Hardware Board running Unix like RetroBSD OS

PIC32-RETROBSD

RetroBSD is a port of 2.11BSD Unix intended for embedded systems with fixed memory mapping. The current target is Microchip PIC32 microcontroller with 128 kbytes of RAM and 512 kbytes of Flash. PIC32 processor has MIPS M4K architecture, executable data memory and flexible RAM partitioning between user and kernel modes. The project is open source and hosted at RetroBSD.org

PIC32-Pinguino was used by RetroBSD developers since long time as it’s small and easy to use, but the Pinguino bords processor PIC32MX440 has not enough RAM to hold the RetroBSD, so we got number of requests to release PIC32-PINGUINO-MICRO with PIC32MX795F512H processor which is pin to pin compatible, so we run small batch of these boards and named them PIC32-RetroBSD, these surely can be used with Pinguino and MPIDE, but note that you must have additional PIC-KIT3 to re-flash the proper bootloader, as RetroBSD bootloader is different and we ship these boards with RetroBSD bootlaoder. Also you will need PIC32-RetroBSD-SD for the file system.

We are shipping today free PIC32-RetroBSD boards to the 9 RetroBSD developers.

LiteBSD for PIC32-HMZ144 released

bsd

LiteBSD is a variant of 4.4BSD operating system adapted for microcontrollers. Currently, only the Microchip PIC32MZ family is supported as a target. It is equipped with MMU with paging support, and 512kbytes of on-chip RAM. These resources are enough to build a compact networked embedded system.

PIC32-HMZ144 support is on the LiteBSD Github

PIC32-PINGUINO with MOD-WIFI controlled by Android IoT

Roberto Bacerra made interesting project. With PIC32-Pinguino and MOD-WIFi he creates wireless node and  he wrote small app for Android which can connect to it and control it.

All sources are in DropBox together with the Android app.

 

MPIDE Arduino like IDE for PIC32-Pinguino and Duinomite boards

With this tutorial video below we will show you how to setup MPIDE Arduino like IDE to work with PIC32-PINGUINO, PIC32-PINGUINO-OTG, PIC32-PINGUINO-MICRO, DUINOMITE, DUINOMITE-MINI, DUINOMITE-MEGA, DUINOMITE-eMEGA.

Here is video tutorial how to install MPIDE and add support for Pinguino and Duinomite boards:

MPIDE installation is also described in our Wiki

Why to use MPIDE?

It’s an alternative to Pinguino IDE and Duinomite Basic. You have one more option to use these boards.

Pinguino IDE  ( pinguino.cc ) was made as parallel project to Arduino but for PIC microcontrollers, instead of Java it uses Python for the IDE, with the latest Oracle – Google lawsuit we still wonder if Java was the best choice for Arduino IDE, but nevertheless Arduino was made earlier and managed to attract huge community. Pinguino community is still small and the demo codes for Pinguino are not so many as for Arduino.

Microchip and Digilent financed the release of MPIDE which is pure Arduino IDE fork and thus more familiar for the Arduino community to use. As MPIDE already have good PIC32 support it was very easy to add support for PIC32-Pinguino and Duinomite there.

Why to use MPIDE and C for Duinomite?

Duinomite boards are low cost but powerful boards initially made specially for project named Maximite.
Two years ago we found interesting project which makes Basic computer with just PIC32 processor.
I started with Apple ][ so it was very nostalgic to see BASIC computer made with embedded processor and to control GPIOs and resources in BASIC.

At that time Maximite was advertised as “open source” project, i.e. firmware sources were available for download. The hardware schematic also was present in JPEG format.

As hardware engineers we immediately spotted some weakness in the Maximite hardware design – the author being mostly software engineer omitted lot of hardware features PIC32 have.

While PIC32 have ultra low power modes, hardware SPI, I2C, UARTs, parallel interfaces which could work with MHz clock speed, for some weird reason the Maximite author decided to implement them by bit-banging purely in software – cripple-ing these interfaces to very low speeds only. Low power modes were not implemented at all.

So we decided to improve the hardware – this is how we made our board with low power design, hardware UARTs and SPIs, UEXT and Arduino connectors so Arduino shields like Gameduino etc could be placed on top of the board and so on.

We completed our hardware design and we proudly offered the Maximite author to check it and tell us his opinion … but he told us that he is not interested and demanded us to choose different name than Maximite. It was a quite surprising open source project author to refuse contribution. So we named our board Duinomite (Maximite is also explosive so we wanted to show where our board roots are).

Being mostly Hardware company we couldn’t implement the software our self, so we contacted Ken Seggler who at this time made port of Maximite for ChipKit board with same PIC32 processor. He was unemployed at that time and he accepted to make the port and even to implement our new ideas we had about low power sleep modes, the new hardware UART and SPI, SETUP command for general board setup, Gameduino commands, we discussed on public forum how to implement editor inside the BASIC and label-less commands etc.

Unfortunately this move really pissed off the Maximite author. He saw the Maximite BASIC port to our board as direct competition as now our hardware had more features than his own.

He closed the Maximite Basic source, then wrote one nasty page about Duinomite on his web presenting him as victim of the big bad company who steal his work and removed his name out of it.
From day one Duinomite Basic fork is on GitHub and anyone can check how true these blames are – Maximite author’s name have been always on our Duinomite Basic fork and display on startup . We had to fork his BASIC just because he refused to support our hardware.

Meantime Ken found full time job and couldn’t contribute to the project anymore, the Maximite author released new version of Maixmite Basic with label-less commands, build-in editor and his new Maximite hardware has … Arduino connectors  (surprise surprise 🙂 ), so after all he has listened to us and took our contributions silently back !

Duinomite software left at that stage as no one was interested to duplicate Maximite Basic work and to run in parallel two same language implementations. The Maximite author had one problem though – while Duinomite quality build hardware cost just EUR 20 the Maximite less capable hardware in kit form cost was something like x3 times more and obviously people were buying Duinomite hardware, so to increase his followers he made Duinomite support and offered HEX compiled version of his Maximite BASIC for Duinomite – actually doing what we originally asked him for to do!

As far for the Duinomite BASIC fork – none of the younger and capable developers is interested in BASIC. Most of Maximite / Duinomite BASIC users are 40+ years and just users but not contributors / developers, so Duinomite BASIC development is pretty much dead.

Although Duinomite boards are still high seller, I guess 99% of people buy them and use them as regular PIC32 development board and use C instead of Basic judging from the tech supports questions we get.

Now with MPIDE Arduino like IDE people who are familiar with Arduino can develop on Duinomite too.
