General Discussion / ESP32 MicroPython
« on: March 14, 2021, 09:35:57 am »
I was able to get MicroPython loaded on my ESP32-DEVKITC32D board. I'm using Putty on the RPi 3B to connect via /dev/ttyUSB0.

General Discussion / RPI Zero Portable
« on: March 06, 2021, 09:20:26 pm »
I picked up a dongle like adapter for my RPi Zero running Raspian Lite. This gives me a USB portable Linux I connect to via WIFI / SSH.

BBC BASIC / BBC Micro

Hi Richard,

I just ordered the BBCMicro starter kit from Vilros.

Do you think BBC BASIC would run on it?

ScriptBasic / RPi Zero
« on: February 03, 2021, 02:56:01 am »
As mentioned in the Pico thread I'm focusing my embedded scripting engine efforts to the RPi Zero. I built ScriptBasic from source on the Zero and running on 32 bit Raspian.  I'm working on building a GPIO extension module based on the public domain pigpio and or lg library.

ScriptBasic / Pico
« on: January 27, 2021, 08:53:40 pm »
I'm in the process of creating a ScriptBasic build for the new RPi Pico. ScriptBasic by design is an embeddable highly configurable micro controller scripting engine. It is used commercially by Banner Engineering and Controlled Soutions with their micro controller solutions.

If you have interest in joining me in this adventure, send support@raspberrybasic.org a request to join the forum.

General Discussion / LG Library
« on: January 14, 2021, 05:44:13 am »
I was able to compile the lg library under Ubuntu 20.04 LTS 64 bits on the RPi 4B 8GB with no errors or complaints with the make file included.

Since I don't have anything connected to my GPIO bus I wanted to see if the lgGpiochipOpen() fuction would return anything. A positive response is zero or greater. I got a -78
 as a response. I assume since there is no chips on the bus it's returning an error code. There is an example for the DHT11 which I have that is going to be my next test.

Code: C
  1. #include <stdio.h>
  2. #include <stdlib.h>
  3.  
  4. #include <lgpio.h>
  5.  
  6. #define LFLAGS 0
  7.  
  8. int main(int argc, char *argv[])
  9. {
  10.    int h;
  11.    h = lgGpiochipOpen(0);
  12.    printf("%i\n", h);
  13.    if (h >= 0)
  14.    {printf("Got Here\n");}
  15.    lgGpiochipClose(h);
  16. }
  17.

General Discussion / RPi Gitlab Setup
« on: December 29, 2020, 11:51:49 pm »
I have installed Gitlab-ee on my new RPi 4B 8GB. The install seemed to go fine. Problem is I can't reach the Gitlab login screen.  :-\

I setup a gitlab.basic-sandbox.us DNS A record on my AWS Route53 DNS service. I have reconfigured Gitlab a couple of times with no error.

When I enter https://basic-sandbox.us in my browser it returns the Apache default index.html page.

Does anyone have an idea how to debug this to get it running?

This is a link to the Nim Manual.

It's a good resouce to get started with Nim.

General Discussion / Ubuntu 64 RPI 4B
« on: December 15, 2019, 08:08:16 am »
On AIR's lead, I was able to  install Ubuntu server 19.10.1 on my RPi 4B 4GB. I then installed the Unity Desktop. This is so cool to run what I have on my laptop  on my RPi.

It seems to run well.

I said 5 years ago that I was done with 32 bit Linux. That was until the Raspberry Pi came along. I'm done with hobby Raspbian 32 and relieved I'm running on a commercial grade supported 64 bit OS.

Nim / Nim SB
« on: December 11, 2019, 05:38:36 pm »
I'm working on embedding ScriptBasic into Nim. Basically it's a port of the SBT extension module as Nim extension. This will allow the full functionality of SB and its extensions to be available to Nim dynamically at runtime.

@AIR - I may need some help creating the Nim interface if you have time.

Nim / Nim Introduction
« on: December 07, 2019, 04:25:35 am »
I was able to get the IUP distribution I built for the RPi and Nim to  work together. A "Hello Nim" of sorts.

Code: Text
  1. import iup
  2.  
  3. proc btn_click(ih:PIhandle):cint {.cdecl.}=
  4.     iup.message("Popup", "You clicked the button!")
  5.  
  6. discard iup.open(nil, nil)
  7.  
  8. var btn = iup.button("Click me!", nil)
  9. discard iup.setCallback(btn, "ACTION", cast[ICallback](btn_click))
  10.  
  11. var dlg = iup.dialog(iup.vbox(btn, nil))
  12. iup.setAttribute(dlg, "TITLE", "iupTabs")
  13.  
  14. discard iup.showXY(dlg, IUP_CENTER, IUP_CENTER)
  15. discard iup.mainLoop()
  16.  
  17. iup.close()
  18.
