hi, i'm reading nmea sentences from gps to handyboard. i'm using serial connection through the expansion board. I need to read two nmea sentences (GPRMB and...
Hi! I keep getting Runtime ERR 09 and I cant figure out where its going wrong :-( Ive got a number too large or too small to convert to an integer but I can't...
Yup tried that and still get the runtime ERR :-( Heres my code, would be a great help if you can see anything wrong, im stumped! :-( void main() { int beep; ...
You don't get to pick the sentences you read from the GPS. You basically need to read every thing, each time you hit a $ you need to read the subsequent...
Hi, I have developed a custom board with an HC11E1 running in single chip mode. This board is just a general purpose I/O board. It has no external hardware...
... That is always a dangerous assumption. What are the specs on the pins??? does it have to be held low or high, is it tri-state, is it enabled??? -- Rich...
Rich, I checked to see if it was tri-stated. Definetly not. The TOC3 pin is driven low by the MCU. To address your question as to whether or not the pins are...
Justin There is an active board called M68HC11@yahoogroups.com. there is considerably more expertise in the various HC11 models there. You might do well to...
I was wondering If anyone knows or is it possible how we can put the two tracks blob on the same process because each process has an independent task thanks in...
The two track blobs need to be on the same process. I assume you have captured the color information for each. In any case, you need to be able to use...
Ive done a little more diagnostics. When I place the E1 chip into the socket of the handyboard, the test program does not work. This means to me that the...
OK, so my kit from acroname comes in the mail. I spend 8 hours painstakingly assembling it. Test at every step. Everything is going swell. Get all done,...
... from ... Update::: As far as amperage is concerned, I these boards can be used up to the manufactures characteristics, as long as the MOSFETs are equipped ...
hello.i was wondering how can we use the IR in the handyboard to send and recieve data ( characters ).we will use a an IR attached in a laptop .do we need to...
the IR port on laptops is generally connected internally to a serial port, and runs in half-duplex mode. There is a huge amount of literature and free...
Hi, I am building an autonomous robot for mine detection. I am using the HB with the expansion board. I hooked up sharp gp2d12 proximity sensors I currently...
Hello Emile, In testing with the Sharp GP2D12 proximity sensors I have found them to be both power hungry and noisy. My solution to this would be to provide an...
Hi, I want to make a communication between the handboard and the pc using the serial port, how can i send the data from the pc, i know which program to run in...
the hyperterminal program that comes with windows should be able to do this. you'll have to close interactive C first or it won't be able to use the serial...
I believe you need to start with the i2c bus interface. There are some examples in the files section of the group. I personally haven't tested them, but I...
I'm sorry that I'm a beginner in handyboard and I don't know what is i2c bus interface, can you explains what it is and teach me how to put the SRF08 with the...
If you search google for "serialio.c", you'll find the serial code for the Handyboard. It's fairly simple; just include it in your main program and call...
Sorry, I don't think I am up to that. I am not sure if there are any ultrasonic rangefinder implementations that do not use the expansion board. The files...
I have searched over the files section of this board but I can't find the information I need. I just want to use the SRF08 as an analog input to the...

Sonar requires a send signal followed by a timed reciept of the recieve signal. My understanding is the SRF08 provides a command driven sample and a recieved...
