Re: Slighly off topic ;-)

i'm starting to be happy again i once ordered some cheap tiny stm8 boards. might end up doing something with them after all XD. looking forward to this :) I think some people are working on the Armduino core to get it to work on the STM8, and have some success I'm not sure whether the STM8 is arm o...

Re: Slighly off topic ;-)

For some reason the STM8 still seems really popular with manufacturers Possibly its he knock down price. I think STM8 has sold 3 billion of them and still get massive sales figures Lots of low end devices still use them. Personally, I'll mainly be using the STM32 but some devices I want to reverse e...

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...

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...
