CH32V307VCT6 development board

[Richard]

Dobrý den,

neporadil by prosím někdo, jak používat knihovnu Ethernet na této desce?
Nemohu přijít na to, kde dělám chybu.
Jde mi o kompilaci kódu původně určeného pro Mega 2560.
Používám Arduino IDE 2.3.7
Na mega se zkompiluje v pořádku, ale na ch32v vyplivuje tuto hlášku:

In file included from /home/r/Arduino/webserver-original/webserver-original.ino:7:
/home/r/Arduino/libraries/Ethernet/src/Ethernet.h:52:10: fatal error: Client.h: No such file or directory
#include "Client.h"
^~~~~~~~~~
compilation terminated.
exit status 1

Compilation error: exit status 1

Na stará kolena si začínám hrát a nedokážu s tím pohnout.
Předem děkuji za pomoc a rady.

S pozdravem Richard

Ahoj,

klasická Ethernet.h knihovna z Arduina (pro Wiznet W5100/W5500) na CH32V307 nefunguje – proto ta chyba s

Client.h

a dalšími hlavičkami.

CH32V307 má vestavěný Ethernet MAC + 10M PHY (RMII), takže potřebuješ úplně jinou knihovnu/stack (nejčastěji LwIP portovaný pro CH32).

1. Nejdřív správný core (pokud ještě nemáš):
   • Přidej do Arduino IDE → File → Preferences → Additional Boards Manager URLs toto: https://github.com/openwch/arduino_core_ch32
   • Pak Tools → Board → Boards Manager → hledej CH32 a nainstaluj CH32 MCU by WCH
   • Vyber board: CH32V307 EVT (nebo CH32V307VCT6 pokud tam je – podle tvé desky, např. YD-CH32V307, EVT-R1 apod.)
2. Odstraň klasickou Ethernet knihovnu
   • Buď v Library Manager odinstaluj Ethernet (od Arduino)
   • Nebo ručně přejmenuj složku ~/Arduino/libraries/Ethernet (aby nedělala konflikt)
3. Ethernet knihovna pro CH32 – nejlepší možnosti (2026 stav):
   • Hledej v Library Manager: CH32 Ethernet, WCH ETH, LwIP_CH32 nebo Ethernet_CH32V
   • Pokud nic nenajdeš → ručně z githubu (nejfunkčnější repozitáře):
     • https://github.com/openwch/ch32v307
       → složka EVT/EXAM/ETH/WebServer – tam je hotový příklad webserveru v C (LwIP) – lze to portovat do Arduina
     • https://github.com/ddrown/ch32v307-lwip
       → čistý LwIP port pro CH32V307 – dobrý základ pro vlastní integraci
     • Community-PIO-CH32V nebo forky – někdy mají Arduino-friendly LwIP wrapper
   • Po instalaci zkus příklady přímo z knihovny (WebServer, HTTP client apod.) – ne ten starý pro W5100/Mega!
4. Typický kód (příklad inicializace – uprav podle knihovny)

   Kód: Vybrat vše

   #include <LwIP.h>               // nebo <CH32_Ethernet.h> / <WCH_ETH.h> – záleží na knihovně
   
   byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};
   
   void setup() {
     Serial.begin(115200);
     while (!Serial);
   
     // Nejčastější varianty inicializace:
     ETH.begin();                    // nebo Ethernet.begin(mac);
     // někdy potřeba: ETH.init(); nebo ETH.begin(RMII); 
   
     if (ETH.waitForLocalIP(10000)) {
       Serial.print("IP adresa: ");
       Serial.println(ETH.localIP());
     } else {
       Serial.println("Ethernet selhal!");
     }
   }
   
   void loop() {
     // tvůj webserver kód atd.
   }
   

Pokud to pořád nejde:

• napiš sem, jakou přesně desku máš (na desce je obvykle napsáno YD-CH32V307, CH32V307 EVT-R1, vlastní PCB atd.)
• pošli screenshot chyby po kompilaci s novou knihovnou
• já ti pošlu konkrétnější link + minimální funkční WebServer sketch

CH32V307 za ty prachy je s tím Ethernetem opravdu super hodnota – držím palce a nevzdávej to!

[Richard]

Ahoj,

mockrát děkuji za radu. Myslel jsem, že to bude knihovnou.
No budu muset trochu bojovat. Je mi 53let a zbytky mozku již nejsou tak rychlé.
Zkusím to a dám vědět.

Potřebuji totiž více adc vstupů než má mega a ch32v307 mi požadavky splňuje, navíc je kompaktnější a vypadá to profesionálněji.
Děkuji za ochotu a radu, kterou asi pochopím a možná dokážu realizovat.

Tak zásek hned na začátku, vůbec netuším, jak naintalovat z githubu tu knihovnu do arduino ide.

Tak se mi podařilo toto:

[Richard]

Z těch knihoven, cos mi doporučil mi to nenašlo nic.
Pokoušel jsem se instalovat z githubu ručně, ale kousnul jsem se na hlášce internal error 13
Takže zatím bez výsledku.

[Caster]

Jsi na dobré cestě.

Tvůj kód je velmi blízko funkčnímu základu pro raw lwIP na CH32V307 (s manuálním RX queue a netif output stubem), ale chybí klíčové části, které spojují lwIP se skutečným hardwarem Ethernet MAC/PHY na CH32V307. Bez nich se paketům nic nestane – ani neodešlou, ani nepřijmou.

Napiš, jestli máš desku s LEDkami na PB8/PB9 (link/activity) pošlu ti pak přesnou úpravu kódu. Případně sem vlož fotku tvé desky nebo odkaz, kde jsi ji koupil.

P.S. Je mi 64, programování MCU/CPU 8/32/64 bit mám jako koníček .

[Richard]

Mockrát děkuji kolego za útěchu. Vidím, že ještě není pro mně nic ztraceno, jen neházet flintu do žita.

Desku mám přesně tuto:

https://www.aliexpress.com/item/1005007 ... in_prod%3A

Uvítal bych příklad typu: zapni/vypni LEDKU přes webový prohlížeč.

Ono jsem si to představoval asi moc jednoduše.
Chtěl bych si přizpůsobit něčí hotový kód určený pro MEGA 2560, ale to asi nebude tak jednoduché.
Proto bych uvítal hotový okomentovaný příklad, abych se mohl podrobně seznámit, jak to funguje.
Ani se mi nepodařilo nainstalovat knihovny z githubu.
Problém s angličtinou.

Pokud by byl velký problém s úpravou původního kódu, nebylo by jednodušší se naučit prostředí přímo pro ch32v?

[Caster]

Ten odkaz bohužel nefunguje, pošli prosím správný.

Nemáš tohle: CH32V307VCT6 development board RISC-V core support RT-Thread onboard ?

[Richard]

Ano, to je ona.

[Caster]

Jasně — tady máš hotový Arduino .ino pro CH32V307VCT6 dev board (CH32duino / openwch/arduino_core_ch32). Je to „bring-up“ program, který:

• rozběhne Serial (a čeká chvilku na monitor),
• otestuje LED na PB8 a PB9 (na těchto deskách se často používají jako ethernetové LED link/activity; PB8/PB9 se zmiňují i v lwIP příkladech pro dev board),
• zároveň umí blinknout i LED_BUILTIN, pokud ji core/board definuje,
• (volitelně) zkusí inicializovat Ethernet, pokud máš v core k dispozici hlavičku ETH.h – když ne, sketch se normálně zkompiluje i bez Ethernet části (jen vypíše, že ETH.h není k dispozici).

Poznámka: CH32V307 má Ethernet MAC + integrovaný 10M PHY.
V Arduino světě je ale Ethernet podpora hodně závislá na tom, jakou verzi/fork core a knihoven používáš (někde je to přes LwIP/WCHNet). Proto je to udělané „best-effort“ a s compile-guardy.

Co od tebe potřebuji, aby Ethernet běžel „na jistotu“ (bez hádání API)

Napiš mi prosím přesně, co máš v Arduino IDE vybrané:

1. Board (název položky v Tools → Board)
2. Verzi CH32 board package (Boards Manager → CH32… → verze)
3. Jestli kompilace najde ETH.h (ano/ne) a případně první chybu z kompilátoru

Pak ti upravím .ino na konkrétní Ethernet API v tvé instalaci (DHCP + třeba mini webserver / UDP test / ping), aby to bylo 100% kompilovatelné a funkční na tvé desce.

[Richard]

Moc děkuji.
