Re: OV7670, Generic STM32F103RC and ILI9341 display

FYI. I tried to get my camera and display working today, but found a load of wires broke off after I took it along to a Arduino club to show them some things you can do with an STM32. So it took me a while to work out where all the wires went and to sold them all on again (about 6 wires broke off th...

Re: aerospace engineer

When I looked at the MPU9150 I was using a library called RTIMU, but I must admit I didn't fully understand all the maths. I was hoping to get the the rough position of a object using the MPU9150 as an IMU sensor, but it was no good at all because any small errors got double integrated and hence the...

Re: aerospace engineer

HI Arthur

OK. That explains things ;-)

I originally started to look at the STM32 to process data from one of those IMU sensors

Re: aerospace engineer

Hi Arthur Sounds like an interesting project. I just wonder why you need such a powerful mcu for what appears a simple task. How are you measuring altitude ? I presume its barometric pressure? I know the Bosch sensors like the BMP280 are good at measuring changes in barometric pressure in a domestic...

Re: Complete dashboard for an old car

Thanks for posting.

There are 4 or 5 people on the forum who are building car displays.

At least one other person was trying to use a Nexion display, but I think the also has problems with it:-(

Re: Hello

I think there is a niche for the STM32F103 as a good value workhorse, but there are soooo many other MUCs available nowadays. I doubt I will do anything constructive with them beyond (hopefully) getting them to work. I have done a fair few projects and have found the Arduino Nano is almost always c...

PR to remove compile warnings buy adding __attribute__((unused))

This PR https://github.com/rogerclarkmelbourne/Arduino_STM32/pull/380 Changes a lot of files and adds __attribute__((unused)) to functions, where the compiler was giving warnings for unused Looking at some of these, I think there are underlying bugs which the compiler is reporting, and rather than m...

Re: LoRa modules (AI Thinker Ra-01, SX1278)

Well, that about sums up the kite from KMart. I thought I was getting a deal at $9 AUD ($6 USD) but I was wrong. Edit. Ray you changed the picture .... BTW. I used to do a lot of kite flying as a kid, and we had one of these RAF rescue kites from military surplus https://www.google.com/search?tbm=is...

i bet that You forgot about me? Or maybe You posted it somewhere else then here https://github.com/rogerclarkmelbourne/ ... /libraries ?
Can't you just add Steve's library to your Arduino Library folder ?
