Here you have Modbus RTU working on CH32V307VCT6.
Connect an USB-TTL adapter to A9/A10 and use RMMS (RADZIO MODBUS) 19200, 8N1 to test.

If someone would want to help me port also Modbus TCP will be very usefull!

you are so great!??The code quality is so good!
這個(gè)人將freeMOdbus移植到CH32V307上了。他是羅馬尼亞的一位專(zhuān)家/科學(xué)家，我在IEEE上看到他的名字了。
建議管理員保存好這類(lèi)高質(zhì)量資料，方便其他用戶(hù)使用和參與開(kāi)發(fā)
Please check also Modbus TCP example for the CH32V307VCT6 :
great work! it's very cool!
大概看了RTU的移植代碼，基本上都是參考官方的例程來(lái)移植的，并沒(méi)有看到什么亮點(diǎn)。
依然是接收靠串口接收中斷收數據、發(fā)送靠空閑中斷發(fā)數據…
如果波特率上到2.5mbps，感覺(jué)有丟數據的風(fēng)險或者在接收120個(gè)寄存器時(shí)短時(shí)間250個(gè)接收中斷轟炸，其他低優(yōu)先的中斷得跪，又或者主循環(huán)周期很遭罪。
依然是僅支持唯一串口、唯一實(shí)例。
講真，在實(shí)際項目中我從來(lái)不用這玩意，還是自己弄自己的更方便。
講真，git上有不少開(kāi)源的modbus都比FreeModbus優(yōu)秀很多很多。

Dear Mr.?Zaxife?:
I know the following products very well:
1.?Janitza-UMG-604-power-quality-monitor
2.?Hydrocal-1005-gas-in-oil measurement
3.?Qualitrol-Tguard-408-fiber-optic-temperature-monitor
If those giants use only one Modbus 485 port, and it works for years at only 19200 baud rate, than
I am realy happy with my humble example! :)
The work started because I didn't found in the internet many examples of Modbus, Websockets,
for the CH32V307, which in my humble oppinion is a GREAT, again, a GREAT MICROCONTROLLER!
The FreeModbus is a great library!?
Good luck and fortune!
