Re: P-channel MOSFET for 3.3v logic.

Id say it's off topic since the question was about Mosfets, not STM32 ;)

Re: P-channel MOSFET for 3.3v logic.

Thanks for fast response!
Good, I'll add this component to the BOM then.

P-channel MOSFET for 3.3v logic.

Hi. I'm investigating the possibility to integrate a STM32F103C8T6 on board of an upcoming, size restricted project. So far I've dug through schematics of a couple maple variants and seen some interesting features: The ITEAD maple (thanks Roger for showing this to someone else over at the arduino fo...

Re: f407vet6 & f407zet6

I'm using STM32 Discovery F407 found under Tools -> Boards -> STM32F4 boards
Not sure if it's the stm32duino version or not.

Re: f407vet6 & f407zet6

Hi! I bougth this STM32F407VET6 board off AliExpress. I'm trying to upload sketches to it using a Baite ST-link v2. First step is just a blink program. How ever, even though I use PB9 as output, I'm not seeing anything happening on the board itself. This is the verbose output from the compilation an...

Re: Self driving RC car

Thanks Roger. Yes it could be that I got some factory rejects because I didn't order them from the Baite store. I'll keep that in mind.

Re: Self driving RC car

One let the smoke out when I plugged in the USB cable (I might had a bit too much current draw on the onboard regulator). I'm not sure what happened to the other one, it's just dead.

Re: Self driving RC car

Did some more work on the steering this afternoon. rStkCV3VhRI The Maple can handle a lot of computing! I included a secondary PID to adjust the speed, along with filters for all 7 sensors. Adjusted the gains for the steering PID, it's finally satisfactory. In the video the robot runs for 2 minutes ...

Self driving RC car

Howdy. This is an autonomous vehicle, a small RC car. I build this for (winning) a competition called robot folkrace, which looks like this: 5gDd7GlaQIo And the rules (in English): http://www.robotchampion.se/wp-content/uploads/2013/10/Folkrace_2013_SRC_en.pdf My progress so far: Bought a small 1/24...
