Hi all, i'm currently trying to learn using HID Maker FS. But i'm having a problem here. The code it generates doesnt wotk on my board or even the demo board from microchip. I followed the instruction in the manual too. It has a warning of "radix supersede by command line" but i'm not sure if...
Hi guys, i'm currently learning the firmware code for microchip pic18f4550, generic USB HID. I got the firmware from lvr.com as an example. one of the header file, HardwareProfile.h has the list of microcontroller that can be used, and then a specific HardwareProfile header file is tied with...
RF driver
Hi all,
I am looking for an RF driver / RF amplifier that has P1dB output at least 33dBm. THe frequency range is primarily 50-150MHz, but wider range is also ok. Efficiency is the issue here, as i already have one that has 25% efficiency(34-35dBm output with 12V@1000mA power supply)...
Thanks for the reply, but i have found the problem on the circuit, pointed by cdh7 and LvM. And once again, the circuit i posted is NOT the circuit i'm using, i'm just putting it to show the configuration of the op amp i use. the op amp i use is opa2674. Thanks
Ha, thanks cdh7, it works. I don't know why i never thought about it before. And for karesz, yes i know that it is a wrong model, i just put it over there so i can draw the schematic, not for simulation
Hi, i'm sorry but i don't get what you're trying to say about the
"clear can it (so) never work:-)
If you takes inputs 2/3 >> need pin 1 as output to use."
and this is just the model i grabbed out of OrCAD, so this is only a picture, and it might be wrong. And i know 100% for sure that on the...
hi guys,
i'm working on familiarizing myself with the pic18f4550 firmware for usb HID device right now. I am currently looking for where the pin out configuration is typically done within the firmware(which pin is out, which pin is in, which pin is LED, etc). Is it in hardwareprofile.h or is it...
Re: help for pic18f4550
hi btbass, i'm sorry i left out the detail. I already have all of those software and packages you recommend. what i mean with c++ is that i will also need to create GUI to interface with the board. and that one is using c++ builder. my bad for mis information. i use HID...
help for pic18f4550
Hi guys,
anybody out there willing to assist me in USB programming with pic18f4550 with C++(preferably C++ builder)? i've read books, examples, and many others. But i think i'm missing the bigger picture and making it complicated. The help i need will probably be a little...
Hi guys, i have question about USB HID firmware and GUI programming. Just say if I have a completely working software and firmware with one USB pcb board configuration(lets say board A). If i want to use the same software and firmware on another board(board B) with same microcontroller, but...
Hi franckcl, my project is kind of in a halt right now because i have other things to do, but i managed to get the board talking to the computer when i plugged it in. assuming that you have the firmware correct(HID), you can refer to FindtheHID() function from Jan Axelson sample...
Ha, well, ideally i want to learn and get a final product quickly...but i guess i have to choose one of them...I guess i'll lean toward quick final product...so you say class AB?
but i also read before that class AB does not perform well for low signal application...
