Re: Analog Pin Numbering

I forgot about the Nucleo, as very few people on the forum use them. I cant remember if there are #defines in the variant file for the Nucleo F193RB, for the analog or digital pin numbers. But if not, they could be added. However for the BluePill etc, I think it could cause problems adding definitio...

Re: Audio DAC

I know some people also use an external DAC and the I2S thats available on the higher end F103 e.f. RC or better.

Re: STM32F3 Discovery board support

Try PM'ing @danielef and ask him about his F4 port of the STM Core The official STM repo's are here https://github.com/stm32duino Its hard to know which one to base the F3 upon. The F1 core has had the most work, as we had to rework it because it was written poorly and initially consumed loads of RA...

Re: STM32F3 Discovery board support

I don't think there is an easy solution at the moment. AFIK the F3 is a lot different from the F1 and from the F4, and when I discussed things with Avik, he said that there was a lot of difference between the devices in the F3 range so it was not easy to add support for any of the F3's that he does ...

Re: Analog Pi Numbering

The problem with numbering pins in this way, is that none of the physical hardware is marked with those numbers. Most boards are labelled with the official STM names for the pins e.g. PB5 The Maple mini just has pin numbers. If there was a board which specifically had those pin names on its silkscre...

Re: STM32F3 Discovery board support

I dont know if you will be able to simply take F1 libraries and modify them. The F3 core is only part of the repo to save it from being lost. I forget who ported the original LIbmaple core to F3, but they abandoned it. A load of work has gone into the F1 and some work into the F4 over the last 2 yea...

Re: news: Arduino STAR OTTO development board

Did anyone else notice the connectors on the underside of the board? It would need to come with pillars, otherwise it will not rest flat on a bench. Shame the video didnt have any commentry. I also presume they are still using a modified version of libmaple as their core, because AFIK STM have not f...

Re: Need advise on logic analyser

I have a logic-8 and logic-16 (clones), and the 16 only works at 100Mhz if you have 2 channels It drops to 50Mhz for 3 or 4 channels. I think it drops to 25Mhz if you have more than 4 channels (though I can't totally remember) If you want to look at SPI then 4 channels should be enough, even if you ...

Re: Hello from Croatia

Hi

If you have used the AVR Arduino before, the transition should not be difficult.

There are some common problems which people encounter, so please take a look at the FAQ thread.
Also we have a small wiki. wiki.stm32duino.com that has useful information.

Re: Back port to Arduino

Why are you using a nano for the other version. There is virtually no cost saving.

I now only use AVR arduinos if I need 5V signals or if some library is far to hard to port to STM32.

Edit.

Porting to AVR is probably harder than porting from AVR
