ZBasic Forum

I concluded that Python has no role in embedded system unless the app can stand the bytecode interpreter overhead. What does "bytecode interpreter overhead" mean? Speed and memory? Over the years I have programmed engineering solutions in Basic, Pbasic, Visual-Basic, Fortran, Pascal, Cobo...

It was a major effort to implement generic target capability. It will take additional effort to support other families of devices and supporting a 32-bit flat memory model will require yet more effort. Definitely an impressive effort. Hopefully you are considering 32bit devices because targeting mo...

The purchased license key enables the current version and does not expire. Just want to verify that if a typical compiler update becomes available as they already do in the course of a year (barring "major" updates), the license key will still apply, correct? What if I purchase a new comp...

Is the License product actually the compiler software or just a license key? If the Compiler is actually the free download from the ZBasic homepage, does this mean the License product works in perpetuity?

The producer could install the ZBasic-compatible bootloader on the hardware but the buyer would still need their own Generic Target License in order to build applications for it. Yes, I'm with you now. This arrangement will definitely save money for customers like myself money. I have seven ZX-40 a...

Congratulations. Arguably you are now competing with BASCOM, FastAVR, etc., although your VisualBasic is far superior. For me, just as impressive is the Zbasic documentation - I find it comprehensive, all-inclusive and highly organized. I've looked at several including Leaflabs, RaspberryPi, Corridi...

You can avoid the inversion by sinking current through the LED and then taking the isolated signal from the collector of the transistor... I'll try your suggestion. Separately, I FOUND SUCCESS with my PWM problem. Also, the ANOMALOUS INTERACTION BETWEEN THE ZX40N AND MOTOR DRIVER IS GONE. The optoi...

I wired up a PS2501-4 optoisolator to my project. The motor-driver logic signals that control fwd/reverse motion function correctly. The PWM signal does not work. The ZX-40n is sending a 20khz PWM to the optoisolator. My voltmeter detects that frequency on the output, but the output RMS voltage is n...

Are you performing the test steps with a direct serial connection or are you trying to use an XBee link? No. I'm using a hard serial line via a dual CyberSerial pci card (COM1 & COM2). The X-CTU software includes a terminal that allows user to select COM port. I used COM1 in steps-B1 through B5...

The hysterisis aspect of ATN downloading makes it difficult to explain steps. I'll try my best to clarify with as few steps as possible. Step-B1: Enter program below. Configure IDE to use DTR-toggling downloading. Execution baud rate set at 19200. Compile & download following code. Result: good ...

I downloaded the latest installer (IDE v1.5.12) and no luck. "Device failed to respond to ATN character..." at dkinzer step-12. And as anomalous as it seems, while in ATN download mode, changing com1speed and Execute Options baud rate to 19200 makes it all work. * Not sure where to go from...

Yes, I'm now with you on the "hysteresis" effect associated with ATN downloading ("first download the modified program using the settings in the program that currently resides in the device"). I followed steps 1 through 11 as instructed and all behaved as you predicted. But then ...

Not sure where to proceed from here. Confusion... the following code complies just fine but fails to download - the IDE says "Device failed to respond to ATN...". Option ATNChar &H04 Option com1speed 115200 Sub Main() End Sub The "Execute Options" baud rate wa...

I tied the ZX40n device directly to my CyberSerial PCI card. The first image shows the "Serial Port Options" selected to download code by DTR toggling. The second image shows that the following code compiles fine, but displays random characters for inexplicable reasons. Option ATNChar &...
