Re: Problem using RTS/CTS with USB serial

Excellent, it will be great if you can narrow it down any further.

Since the results are positive overall we'll move on with applying the current changes to the FTDI driver as well in the meantime.

Re: i2s and digital microphones

Apologies if I am missing the obvious but how do we specifiy the DMA channel we want to use in the DMATransferRequestEx function? By design the DMA driver chooses the next available channel that suits your requirements, the Flags field of the TDMAData allows you to request a bulk channel (DMA_DATA_...

This one seems to need libgc (the C garbage collection library), if you compiled that for Ultibo the rest looks like it would also compile.

Re: Neural Networks

There is a Pascal port of this C Neural network https://github.com/glouw/tinn Useful links too. Small enough I might be able to figure it out ;) https://sourceforge.net/projects/pastinn/ No dependencies? At a quick look it appears there are no dependencies at all and it uses stock standard Pascal c...

Re: IR Touch screen

Leave it with us and we'll post an update to test this. We've just pushed an update to GitHub that adds rotation support to the mouse interface and we've updated the USBIRTouch driver to make use of it. If you download the latest RTL and update as per the wiki instructions and then download the lat...

Re: Change timer to 19.2Mhz

I use raspberry pi 3 model. I know that there are two usable timers per core and they are set at 1Mhz. But I am not enough 1Mhz. So I want to change timer to 19.2Mhz. How can I do that? Hello, We originally designed Ultibo to work with any available clock speed but your question made us realize we ...

Re: Problem using RTS/CTS with USB serial

If we post an updated version of the PL2303 driver containing these changes are you able to undertake some testing or do you need it to be the FTDI driver instead? I can test the PL2303 driver changes when you are ready. I did not study the PL2303 driver but should not be an issue. Okay, we've fini...

Re: i2s and digital microphones

a) which clock is being used to generate the PCM_CLK b) how is this connected to the actual GPIO output. The clock manager is partly documented in section 6.3 of the BCM2835 Peripherals document, it only talks about the GP0/GP1/GP2 clocks but the control and divider information is actually the same...

Re: Reading from a wireless SD card

Is this the expected behaviour of Ultibo? I know it is a bit of a weird scenario, so that is why I am asking. The Ultibo filesystem caches the directory entries in order to avoid reading them from disk each time you want to look for a file, because FAT is not designed to be a shared filesystem (two...

Re: Conditional compilation by Target controller?

It's funny how sometimes you don't think of the obvious solution until you try to explain it to someone else. After posting the above I suddenly realized there is an even easier way to add a define that will be automatically available to every project regardless of whether you compile from the comma...
