Re: PPP connection fails (update)

That was a really good find. It may help resolve an ongoing mystery about weird GPRS modem issues.

Re: Permissible Voltage Levels to UARTs on SB70LC Board?

We are changing the docs to read LVTTL 3.3V max.

Re: Permissible Voltage Levels to UARTs on SB70LC Board?

The SB70LC is NOT 5V tolerant.
3.3V levels only. I need to hunt down and kill the TTL comment, where was that?

Re: __attribute__((packed)) and __attribute__((aligned(4)))

If you don't say packed you example structure will likely look like: struct TemperatureData_t { BYTE TempSensorStatus; BYTE TempSensorError; BYTE pad[2]; double Temperature; } You can allways tell if there is padding what does sizeof(TemperatureData) return? Unless you are using a dual port RAM wher...

Re: Network Mask

The mask should match for a variety of reasons, but I don't think its related to the ping stopping. Wee the two boxes connected to the same hub? Were there any routers involved? Could you still find the device with the ipsetup tool? I've seen firewalls do this, ie they allow some communication, but ...

Re: DHCP Server Service?

This has been on the todo list for awhile. It has not yet been done to my knowledge. Chris the need is so you can walk up to an instrument with a netburner in it, plug in your laptop and talk to the netburner without reconfiguring the laptop from its normal DHCP mode to static IP. To be really usefu...

Re: PIT ISR prioity Timing

Your problem is in the OSTimeDly The way OSTimeDly works is that the time delay can be anything from n-1 to n It works by setting up a time delay counter and decrementing every tick. when it gets to zero the timer is released. Since your pit interrupt is asynchronous to the Timer tick, then your del...

Re: SBL2e application development questions

It does not presently have a source level debugger. The ticks could be modified, why do you need modified ticks? Almost always better to use a timer. Can you give an outline of what you want the SBl2E app to do? If you can do it on a SB70LC expect to spend 4 to 10x as much time getting all polished ...

Re: How to send fragmented UDP packets

int SendFragmentedUdpPacket(IPADDR to, WORD source_port, WORD dest_port, PBYTE data, int length);


This function will send larger than MTU udp packets.

Re: Strange operation with Quadrature on eTPU

Slowing down an edge detection input with an RC filter is not always a good idea. If you can see the whole pulse on a scope then you cant see noise, this should respond to glitches as narrow as 50nsec. Try a Schmitt trigger in front of the input and see what happens. Or generate some quadrature sign...
