There are random corruptions happening on the SPI display, where some other pixels outside of the normal rectangle are overwritten. I don't know yet if that's an issue in my driver (timing violations maybe?) or with the SPI interface, but because the entire frame is overwritten each tick, the corruption is only visible for a short amount of time.
ICSP is (SPI like and is,) using synchronous serial (CLK, MOSI, and MISO) method to perform in-circuit programming.
You have to find a proper library to perform such task, probably in bitbanging style.
It seems that you would then get the maximum response from your sonar, and then shuttle the data from the arduino chip one to the omega. For around $25 (20 for the dock, and around 4-5 for the sensor) you could get this done much in the same way you have before, without having to depend on linux timing being a bit inadequate for the task.
Thanks for the swift reply. Although it is a bit disappointing.
I am not that much worried about the display though. My major concern is that power management. I am wondering at the moment how this issue is being handled in a simple Amazon Kindle device? AFAIK it is Unix/Linux/Android based (not exactly sure) using 800MHz i.MX ARM processor and able to run for a whole month without recharging. Of course ever XX minutes it goes into deep sleep somehow. I will most probably continue the research with something like this, although the Omega was much more appealing with its 9$ price tag :)
Anyway ... thanks again for the reply and the involvement.
hi, looks interesting. I read that there is a new version coming but there was no date on that notice so my question is, do you have a new version coming or is this current board the new version you mentioned? thanks.
