Video Playback using an RLP

[SupportAdmin]

Do you want to learn more about RLP? Or be able to playback a video stream?
Check out our blog!

Update: the project is complete and up if you want to try it

Will RLP be available for all GHI .net products?

I want to test RLP on the Embedded Master Module.

[SupportAdmin]

GHI invented RLP It is already available on ChipworkX but as of now we do not have plans for EM yet

[4dotnet]

Can GHI tell which timer for ChipworkX is used for the MicroFramework?

we are testing RLP and want to implement a ISR with a timer.

[SupportAdmin]

Timer 0 is reserved, 1 and 2 should be free.

Installing ISRs in RLP will be a supported feature but currently we do not support it just yet.
Why do you need to use timer? Just to test ISR?

[4dotnet]

we want to handle a uart based protocol
at timer interrupt a statemachine will handle the protocol stack

we want to handle the complete protocol in native code with RLP

Is it NOT possible to use RLP for starting a timer interrupt?
(even not for catching a UART interrupt  )

when will this feature be available?

Best regards

I theory, ISRs are available and possible now but we do not have examples yet. A new SDK will come this/next week that will add many new features and enhancements and examples for RLP. Examples for ISR installing using RLP will come after. If you can't wait for few weeks  then we can work with you one-on-one to help you out.
Does your protocol require such accurate timing? Most UART interfaces work fine with 10ms or even 100ms delays. What I mean is why no call your state machine handler from a timer in managed code?

RLPs are great but not as simple as managed code and so you should use them only when it is a must. Sometimes you can device the code so, for example, the state machine and UART driver is in managed but the CRC calculation and data parsing is done in RLP.

I would like to move my real-time protocol handler (that I today have in a separate Atmega chip that I communicate with using SPI) to a RLP.
The problem is that the USART protocol has a 5ms maximum timeout after a packet (set of bytes) is received, but I should really read the received byte within 1 ms after it is received to calculate the potential respons.

Will this be supported by the new SDK so that I can hook into the USART interrupt ?

Why next release? You can do it now!
Just keep this in mind, once you use the UART in RLP then you must not use it in managed code. 5ms or 1ms is no problem for 200Mhz ARM processor!
