Hi guys, I'm currently programming a software oscilloscope based on C++ and DirectX, thus the performance is very good. It works directly off the serial/COM ports. I was just wondering..is anyone else interested in such a thing? I'm programming it for my Arduino BUT it should be…

This sounds like a really This sounds like a really interesting project! specially if you get it working on Picaxe ! Would want a bit more info on it; what so I need to wire up and that sort of stuff…

Picaxe Well, I’m not gonna make it work with a Pic since I don’t have one and don’t intend to get one (ever). But it should work. Serial is serial. As long as you send a stream of bytes (values between 0 and 255) it should work. And as long as the COM port and BAUD rate match, a…

More Picaxe… Just did a quick google on Picaxe serial standards. It seems you’re good to go: 8 data bits, no parity bit and 1 stop bit. Just remember to add N in the serout command before the BAUD rate (eg. N9600) meaning NOT inverted polarity, and it should work fine as is…

Source code added… Source code added at the request of Simon and Tinhead. PS: Still anxious to get feedback from people who actually used the program :slight_smile:

Curious how fast it can go I am from old school and have a dual trace 35 meg (.1 us/ div.). Even that is slow to what they have now. I have seen digital scopes but have to be patient with the time delays. The signal can be come and gone by the time you see it on the screen.

Testing Well I was hoping to get some feedback from other people regarding the performance etc… But here is a small Arduino test program I’m using: byte val = 0; void setup() { Serial.begin(115200); } void loop() { Serial.print(val, BYTE); val++; delay(1); } I’ve …

Hey, Aniss!Thanks for Hey, Aniss! Thanks for posting the code. You are probably right about the win32/directX thing and that it doesnt make sense for a linux user to try to convert it to POSIX. Anyhow, its always more interesting to be able to see what you have done - rather th…

You’re welcome :slight_smile: And on 2nd though perhaps it wouldn’t be SO dificult to export it to other other systems. The serial interfacing (which was the hardest part for me) would have to be rewritten off course. But as you see in the code I wrapped it into 3 functions: sta…

Just wondering… Is it possible to send serial data from a PIC to a PC using the programmer cable? If no then that would explain why you PICAXE folks don’t find this tool usefull. If yes then I recommend trying this tool. Just plug you MCU into your PC (USB or serial) and start s…

You certainly can with a You certainly can with a PIC, many these days even have USART, a built-in serial interface. PICAXE on the other hand use the same μC hardware but have significantly limited capabilities, so I don’t know how easy it is to interface those with a PC via seri…

I´m kind of new with robots, and this could be a handy tool. Could you please upload the soft again. and also the source if that is available

Thanks!!!
