1 The very beginning: JAL FAQ version 1.0 March 23, 2008 1 1.1 JAL? PIC? Where do I start? 1 1.2 Where to get JAL? 1 1.3 Which PIC? 2 1.4 What's all this JAL...
I just wanted to say thank you for the USB examples. I built the serial test circuit and compiled the JAL file for the 18F2455 and it worked on the first try....
Hi, I'm using Albert Faber's USB BOOTLOADER for complire >=2.4l with PDFSUSB v.1.00. The Bootloader go well with FLASH (Write/read/erase) but with EEPROM datas...
Hello everybody, excuse me for the challenge, but I see that the forum is no longer populated by ... 10/10/2011 is there something problem? I have already...
I only know enough to say that the PC has to initiate the data transaction. (It's obvious that USB was designed by industry...It's very un-DIY-friendly.) Mike...
Hi, I'm not sure this has been implemented, some feature in Albert's USB bootloader aren't, maybe this one including ? Cheers, Seb 2011/10/14 despx2003...
Yesterday I bought the book "50 PIC Micro-controller Projects" by Bert van Dam. I already have his first 2 books, so I was amazed that I could not connect to...
... Perhaps a minor glitch, the site is up and running, so if you try again it should work (I just tried it to make sure). Anyway, judging by your name you're...
Right, time to update my progress or to be more exact, update with absolutely no progress what so ever. I have bought a new rs232 to TTL board thus bypassing...
Hi, I was tired of using MCHPUSB and I decided to make a clone using much more lightweight and spartan using the MCHPUSB's original source. The result is...
Just had a thought! Will the speed of the crystal have any effect on the rs232 output?? I know the book is written for a 20 Mhz crystal whereas my development...
Sorry for the inconvenience! I posted the wrong version of the ZIP file! Now I just uploaded the zip file correctly. Please download it again. ;-) have fun! ...
That depends on whether or not your program was compiled for 20 mhz or 4 mhz. If the compiler and your oscillator match then it should work. That also means...
BINGO!!!!!!!!!!!!!!!!!!!!!! Changed the crystal for a 20Mhz one and it now all works perfectly!!! Thanks everyone for your help and suggestions, so onwards and...
If you properly set the 'pragma frequency' to 4MHz and library you use correctly calculates divisors then no - it does not matter. You have to do step by step...
Thanks for your reply, I have now (finally) solved the problem by fitting a 20Mhz crystal. I think your last sentence "Apply common sense and read the manual"...
Right, in this case you changed the hardware to match the software. What a_b_aldus and myself were trying to get you to understand is that you could have...
Hi Shawn (and Arcady) I do understand what you are saying, it's just that in this case I suddenly had a "Eureka moment" when I realised that I wasn't following...
... You claimed to have the exact hardware as described in the book, and yet it didn't work. So from that point of view yes: you did have a hardware problem....
I didn't think he was blaming it on anybody but himself. Seems that he has learned. Hardware mistakes are easy to make, no harm done! We are all here to help...
