How about just byte sequences spitted out from the host PC to receipt printer.. are there any receipt printer programmer guys out there that can help me just the byte sequence and the expected print output. Please help. i really needed it. Just email neoaspilet11@gmail.com
Yeah using windows maybe in Java or much better if stand alone programs. It could be any program as long as it sends data to a serial port. Any help will be much appreciated.
Hello,
any guys that here that had experience with receipt printer programming. I really need some stand alone programs that can send data to an epson printer. it doesnt matter what it prints as long as data are sent via serial cable. Or Anybody know any emulator that can output byte data to a...
Hello Guys,
Please help. I got a Microbuilder PN532 breakout board connected to STM3210C EVAL board. It seems the command to PN532 went through but the reply will only be received when I force the system to power down. Really very weird behavior. The PN532 chip will only reply just before few...

Hello guys,
I having trouble in using C++ for STM32 devices using Kiel UVision4 compiler. It seems the codes are compiled and the compiled codes main() thread is working because it can turn on a LED in the trainer board.
The test program is quite simple, it will light up the LED in the main...
Hello friends,
I am currently evaluating which module to use..
Here are my options
1.) Simcom SIM548
pros:
- there is just 2 voltage rails + VRTC(battery). VGSM = 3.4 to 4.5V; VGPS = 3.3V
- I read some hardware and firmware specs; it seems easy to use
cons:
- connection to the module is via...
pic18 wakeup
Hello,
It seems my sleeping PIC18 cannot wakeup at interrupts via button switches on PORTB. It only wakes at at reset on teh RESET pin.
Any idea how to wakeup the sleeping PIC18 at interrupt (hi to lo transition) at PORTB, pin 0.
Thanks,

Hello,
Any body knows how to do this? Currenty I have to print to pdf manually each file. And my code is more than 120 files. Is there any automatic way to print it all to pdf in just few clicks?
Thanks,
neo
need logic level shifter
any signal from ur RF module to PIC would have no problem even it is a 3.3V logic. Any signal from PIC to ur RF assuming ur PIC is 5V logic and ur RF is 3.3V can be simply voltage divided to get a 3.3V logic.
May I know how is this possible. I am using a PIC18F67J11.. I looked at the sheets and I dont know waht this means. I used two SPI modules for this chip and its working fine. Now I want to add another SPI module that can be multiplexed with the existing one.
Ive checked the S35390A version...
