Re: OV7670, Generic STM32F103RC and ILI9341 display

Ah OK

I think @stevestong was implying that you swap endian ness that way, with the resultant problem in the green channel

Re: Slighly off topic ;-)

But it simplifies the search! Using the single word Arduino you find a lot of results that are interesting. Try to search using ARM, you will get a looot of results that are not useful. True. I got some other interesting stuff in the post, including some IR time of flight distance measuring modules...

Re: OV7670, Generic STM32F103RC and ILI9341 display

There is plenty of time to byte swap correctly.

Aren't there loads of nops in the code ?

Slighly off topic ;-)

Guys I see there is some interest in the STM8 processor, with Armduino porting their core to this (8 bit) architecture, so I thought it was worth making a section of this even though its not a STM32 device, and is quite a different type of device. I just received a couple of these "STM8S103F3P6 ARM ...

Re: Alternatives to Nextion displays?

Looks like the same display + STM32 is available on AliExpress

https://www.aliexpress.com/item/5-inch- ... 68249.html

But it looks like those are basically just a 5 inch display with a STM32 board plugged into the side

Re: OV7670, Generic STM32F103RC and ILI9341 display

As far as i know, @indrekluuk uses the trick that ignores the very first byte so that the high byte of the next pixel will be the high byte of the actual pixel. I dont know, would it help if you set the spi to 16 bit transfer mode? Would the bytes change their order this way? I thought about that t...

Re: BMP Windows drivers missing digital signature

2 things you can try.. 1. In my GitHub account, I have an old copy of BMP. Look for the repo called blackmagicprobe archive_version In there, somewhere are the old Windows drivers. Most people seem to think they install, 2. Alternatively, look at the windows driver installer in my STM32 repo. It has...

Re: OV7670, Generic STM32F103RC and ILI9341 display

@stevestrong I am using platformIO for compiling and uploading. At quick glance it seems that the SPI library that comes with platformIO is this: https://github.com/rogerclarkmelbourne/Arduino_STM32/tree/master/STM32F1/libraries/SPI/src I am using the ILI9341, and the benefit of this, appears to be...

Re: Alternatives to Nextion displays?

Does anyone know what MCU is used on the Nexion or Eve displays.

If we could find one that used a STM32, it's possible that the screen could be used as both the display and the main processor on a project.
Albeit, they may have fancy code for decompressing jpegs etc in them, which would be lost

Re: Learning about 433 MHz radios - how?

LOL. I replied to the GitHub issue before I saw this. I will find the code and email it to you ( as admin I can find the email address you registered with) But I apologise for the quality of the code, as it was just a quick hack to get it to work. And, as I said on GitHub, that "library" is not real...
