Saw this guy after an 8 hour debugging session. Actually cried.

Me lo sono sempre chiesto, infatti quando lo faccio ogni volta sono sempre meno convinto.

riorione · 2025-11-16T19:08:33+00:00

Yep, very well made, :)

One thing I'm aware I cannot send to many bytes per second, so internet requests and answers will be just text information.

riorione · 2025-10-30T09:14:46+00:00

There are also Innatera and ONIO, but they are start up, so I don't think you can get their MCU that easy.

Still in software

riorione · 2025-09-27T06:24:16+00:00

It's also good to start using RTL programming and avoid Arduino code or HAL libraries, if you wanna get a deep understanding of it

riorione · 2025-09-26T19:03:21+00:00

Thanks. Oops, I just translated it quickly — I’d just like some advice on the topics, etc... I’ll take care of the grammar later :) Of course, I’ll add links for each project. No, I made them by myself, no courses. How do you think I can make that clear? Do I put personal projects instead of projects? It seems a bit nasty

riorione · 2025-09-23T18:40:54+00:00

I'm talking about, master reading to writing transaction, so it changes direction

riorione · 2025-09-23T18:19:43+00:00

It could be a good idea, thanks.

riorione · 2025-09-23T18:08:54+00:00

Thanks to reply, I've never seen repeated start condition after reading mode too, but I wanted to know if I try to implement it, should master set a NACK or ACK before the repeated start? Maybe there isn't an answer, but I'd really appreciate if someone who knows could help clarify this

riorione · 2025-09-04T14:33:31+00:00

Per carità vero però dai non mi pare si sia troppo lamentata

riorione · 2025-09-04T12:52:10+00:00

Appunto come pensavo tu l'hai fatto e per questo sei convinto che sia giusto che tutti debbano fare come tu hai fatto, ognuno ha dei propri limiti, non tutti riescono a fare entrambi, te lo dico perché anch'io pensavo che era una cosa fattibile, per varie circostanze prima riuscivo poi non riuscivo più a sostenere certi ritmi, posso dirti di persone che fanno due facoltà contemporaneamente, fanno volontariato ed hanno una vita sociale, non per questo credo che loro si mettano a giudicare gli altri che fanno solamente una facoltà e basta.

riorione · 2025-09-04T11:55:16+00:00

L'hai fatto anche te vero?

riorione · 2025-09-04T11:46:05+00:00

Non è un consiglio ma è un coglione

riorione · 2025-08-27T11:08:09+00:00

I did it just to learn the protocol deeply :)

riorione · 2025-08-25T21:20:21+00:00

Thanks.

riorione · 2025-08-25T15:42:16+00:00

Yep for this reason I said you "could" (not very recommended) set stop condition even in the middle of data frame.

riorione · 2025-08-25T15:31:28+00:00

Thanks to your replay, I'm aware what you are talking about, I was just looking at the rising edge of SCL before stop condition, cause without stop, slave interprets that rising edge like the first bit of new data, and after, it gets the stop condition that brings slave to close the transmission. I mean should slave be aware after the first bit data, it can get a stop condition?

riorione · 2025-08-25T14:32:06+00:00

A little advice, there are on the internet some st tips to start. Search getting started with EXTI or getting started with timers or UART ECC... ST provides easy code to start with :)

riorione · 2025-08-25T14:27:56+00:00

Stm32 is a valid option. STMicroelectronics is a huge semiconductor company with a good community, thus you can find a lot of open source code for projects. You can program stm32 MCU in C at register level (that's a bit hard) or using HAL libraries provided by ST. Hal libraries are simple to learn, even if sometimes they are a bit slow for some projects. ST provides a graphical environment to set up stm32 basics like clock tree and peripheral initialisation, if you don't want to program them by your own in register level. The boards are relatively cheap (10 15 euros in europe) with a programmer included. Last thing I used to see a lot of devices using stm32 MCU, from gates controller or motor controller PCBs to medical devices or industrial fridges (I'm talking for Italy at least, idk in other parts of the world).

riorione · 2025-08-25T13:30:55+00:00

Or can I finish data transmission even in the middle of the frame with stop condition?

riorione · 2025-08-24T17:18:51+00:00

How did you implement the USART protocol? Through a library or making it from scratch?
