Anyone else getting a Error : Not enough memory message when trying to edit a program after running it. Trying to load another program after the above error also gives the same message.

That's an easy one to fix but I'm making no progress at all on TCP and UDP socket support so it may be some time before I post the next alpha |

I have to say that the prospect of TCP and UDP socket support for the Pico W is very exciting. For me, it would change the Pico from something which has been loads of fun to play with to a device that I will actually use in my household monitoring and control designs. For 15 years or more I have cobbled things together using PICAXE plus various tiny routers running OpenWrt, Raspberry Pi ZWs with Lua, and ESP8266 and ESP32 running Annex. I'd much rather use MMBasic on a Pico W. Looking forward to coming announcements. PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

matherp i hate  and love  you, what great news!Because of your earlier statements I got myself an ESP-12E module. Now this runs since today and I think great, check thebackshed forum, maybe someone is interested. And now this! Thank you! And keep going ... ;-)  I will test this on the weekend **joy**  Edited 2023-02-02 06:52 by homa |

Dont know what I am going to use it for, but after understanding that Matherp is developing something for Pico W, I immediately ordered a few. No hurry with the development Peter, I have still to wait a couple of weeks for arrival of the W  |

 hello Peter, i tried running your code with version 5.07.07a1 on my original pi pico w. Unfortunately the setup as in your screenshot does not work for me! Do you have another version? I also have a pi.ico file on the flash drive. Will there also be a way to manage tcp connections yourself? As with the ESP-12E module? There you can manage up to 5 connections. How does that actually look with the pico w? According to Internet data, it can manage up to 4 clients as a SoftAP. Does that mean that up to 4 client accesses to the pico w are feasible? Would it make sense to use the AT commands of the ESP-12E module as a basis for the WEB command? In any case the testing is fun. And I can help you here with pleasure. The attempts 1-6 are actually self-explanatory ... Greetings from rainy Germany Matthias |

Here is a version to play with - what a bu..er this was getting working. Even now it is less than robust - it may never be completely robust. PicoMiteWeb.zip  New command: OPTION TCP SERVER PORT n This is a permanent option and launches a TCP server on the defined port (Use 80 for the example) during every restart of the PicoMiteWeb USE "OPTION TCP SERVER PORT 0" to disable When the server is running it can respond to up to MM.INFO(MAX CONNECTIONS) connections at the same time - currently set to 4. This was the difficult bit to get working as browsers all seem to be different in the way they use connections and do or do-not expect them to be open. Here is a simple example HTTP host Dim buff%(512) Dim myfloat!=16.123 Dim myint%=999 Dim mystring$="The PicoMite Web is GO!!!" WEB ntp Do poll Loop ' Sub poll Local p%, t% For a%=1 To mm.info(max connections) LongString clear buff%() WEB tcp read a%,buff%() p%=LInStr(buff%(),"GET") t%=LInStr(buff%(),"HTTP") If LLen(buff%()) Then Print "_________________________________________________" s$="" If (p%<>0) And (t%<>0) And (t%>p%) Then s$=LGetStr$(buff%(),p%,t%-p%+4) Print "String is ",s$ EndIf If Instr(s$,"small") Then Print "sending picture" WEB Transmit FILE a%,"small.jpg","image/jpeg" ElseIf Instr(s$,"favicon") Then Print "sending icon" WEB Transmit FILE a%,"favicon.ico","image/vnd.microsoft.icon" ElseIf Instr(s$,"HTTP") Then Print "sending page" WEB transmit page a%,"test4.html" EndIf Next a% End Sub and here is the HTML file. NB: the base64 string must be converted to a single line and then xmodemed to the PicoMiteWeb. This string is the PicoMiteWeb icon. <html> <head> <title>PicoMiteWeb Test</title> <link rel="icon" type="image/x-icon" sizes="16x16" href="data:image/png;base64,AAA BAAEAEBAQAAEABAAoAQAAFgAAACgAAAAQAAAAIAAAAAEABAAAAAAAgAAAAAAAAAAAAAAAEAAAAAAAAAAAA AAAAP//ADMA/wD/AAQAFf8AAAIACABZAP8AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAFAAUAVQBVAAUABQUABQBQBVAFBQAFAFAFBQAAVQBVAAUFBQAAAAAABVAAAAAAAAAAAAAAA AAAACREMzERAAAAJkRDMxEQAAAmZEQzMREAAAZmREMzERAAAGZkRDMxEQAABmZEQzMREAAAZmREMzERAAA GZkRDMxH//wAAuzMAALrtAACa7QAArzMAAKv/AACf/wAA//8AAAA/AAAAHwAAAA8AAIAHAADAAwAA4AEAA PAAAAD4AAAA" /> </head> <body> <h1>{mystring$}</h1> This is a paragraph.  Test of a float: myfloat is {myfloat!} Test of an integer: myint is {myint%} Test of a string: mystring is {DateTime$(now)} Test of a missing variable: missing is {missing} </body> </html> Here are the supporting images small.zip I'll now try and explain the new functionality WEB TRANSMIT CODE cb%,nnn% Constructs and sends a numerical response to the open connection cb% and on completion closes the connection. Typical use would be “TRANSMIT CODE cb%, 404” to indicate page not found. WEB TRANSMIT FILE cb%, filename$, content-type$ This constructs an HTTP 1.1 header with the ’content-type$’ specified, sends it and then sends the contents of the file to the open connection cb% and on completion closes the connection WEB TRANSMIT PAGE cb%, filename$ This constructs an HTTP 1.1 header sends it and then sends the contents of the file to the open connection cb% and on completion closes the connection MMBasic will substitute current values for any MMBasic variables or expressions defined in the file inside curly brackets e.g. {myvar%} Variables can be simple, array elements or expressions as in the example. An opening curly bracket can be included in the output by using {{. When you run a program with the TCP server enabled the firmware will automatically create a receive buffer of 2048 bytes for each of the 4 possible connections. Your Basic program should poll these receive buffers using the command WEB TCP READ cb%, buff%() cb% is the open connection and buff%() is an array to receive any data from that connection as a longstring If there is nothing received on that connection this will return an empty string LLEN(buff%())=0 If there is, then the Basic program must respond with one of the TRANSMIT commands in order to close the connection There is more functionality that I need to test further that enables the TCP server to be used as one end of an open link. I will then look at the commands for a TCP client - should be easier. Getting this working to the extent that it is has cost me three full days of my life so don't expect a further update too soon ISSUES: I believe it is possible for a browser to send connection requests and the associated data faster than the TCP stack on the Pico can respond. In this case you are left with a dangling connection as the Basic program doesn't know about it. This needs further work. Various error conditions are not handled so be prepared for lockups and have the reset button handy Sequencing is important - don't connect a client before you have a handler running. Below is a Basic subroutine for parsing GET requests - came from a Pi-Cromite example but not retested - use or abuse as you wish Const maxargs = 32 Dim arg$(1,maxargs-1) 'Function to parse an HTML GET request' ' Assumes that the request starts with "GET /" ' and ends with "HTTP" ' Function parserequest$(req$, paramcount As integer) Local a$,b$ Local integer inpos,startparam,processargs For inpos=0 To maxargs-1 arg$(0,inpos)="" arg$(1,inpos)="" Next inpos paramcount=0 a$=Mid$(req$,6,Len(req$)-10) inpos=Instr(a$,"?") If inpos<>0 Then 'parameters found processargs=1 parserequest$=Left$(a$,inpos-1) a$=Mid$(a$,inpos+1) Do arg$(0,paramcount)="" arg$(1,paramcount)="" inpos=Instr(a$,"=") startparam=1 arg$(0,paramcount)=Mid$(a$,startparam,inpos-startparam) startparam=inpos+1 inpos=Instr(a$,"&") If inpos<>0 Then arg$(1,paramcount)=Mid$(a$,startparam,inpos-startparam) a$=Mid$(a$,inpos+1) paramcount=paramcount+1 Else arg$(1,paramcount)=Mid$(a$,startparam) paramcount=paramcount+1 processargs=0 EndIf Loop While processargs Else parserequest$=a$ EndIf If a$="" Then parserequest$="index" EndIf If Instr(parserequest$,".html")=0 And Instr(parserequest$,".HTML")=0 Then parserequest$=parserequest$+".html" End Function Edited 2023-02-05 23:22 by matherp |
