Hello,
I am currently looking for a test board/circuit that can send a varying duty-cycle PWM signal to an 8-bit AVR Microcontroller and also watch two analog outputs from an LMV612 op amp to verify functionality.
The TM4C123G Evaluation Kit was recommended to me and after reviewing the manual, I had a few questions.
1) I noticed that the available I/O are brought out to headers(pins), but it looks like there is also a connector housing on the other side of the board. Does this give you an option to use either side(pins or sockets) ? Also, I do not see any mounting holes, so I am assuming this is stand alone or can be held together by whatever plugs into it. Is this correct
2) Power Supplies: This can be powered by one of two power sources(On-board ICDI USB cable or USB device cable). I believe the USB Micro-AB cable is provided and can be used for either source by plugging into a PC. Is this correct?
I will also need to power up my target which includes two IC's (ATTINY85-20SU and LMV612MA) which both require 3.3V. Can I piggy-back the power off the I/O header(J1 pin 1 and J3 pin 2) of the TM4C123G or is it better to use a seperate source?
3) PWM signal: Is J4 pin 3 the connection for the PWM signal, if not can you please tell me which pin it is?
4) Analog inputs: Are J3 pin 8 and pin 9 the connections for the analog inputs, if not can you please tell me which pins they are?
5) RBG User LED: Can this LED be configured to turn green if the test passed and red if it failed? If yes, would this be done through the software?
Can someone please provide me support on this application.
Any assistance would be greatly appreciated.
Thank you and I look forward to hearing from you.
Best Regards,
James Demakis
