Hi I've the same problem! I've wrote a first program to solve that, but i didn't work. Look at my message from 16. October. (sonar and overflow) If you don't need that accuray, then you can just use the overflow_counter, but this is not at all (...) (24 years ago, 26-Oct-00, to lugnet.robotics.handyboard)

| | Sonar limited by signed int... change to unsigned?
|
|
Hi, The sonar code is limited to 15' since we are using a signed int. I don't want to change the timer resolution since the multitasker will run slower. The counter only supports an int right? So we can use a signed int and check the overflow flag? (...) (24 years ago, 26-Oct-00, to lugnet.robotics.handyboard)

Hi Naomi. The problem is not with the get_char function, I think that is with the analog function. Try to find this files in your IC/LIBS directory: lib_hb.asm lib_hb.c lib_hb.icb Expens.c HBsensor.c The _raw_analog is a rutine and it is defined in (...)

Dear Mr. Martin, First, thank you for your patience. I'm really sorry to be so much trouble. The Targa thing is easy to explain, so I'll start with that. Yes, the files are all in ZIP archives.
