Re: Raspberry Pi PIC Programmer using GPIO

Hi all. Nice to see that rpp and rpp-tlc is still in use, but in the meantime I have found better software. It is called Pickle, it's interface for RPi is quite simple too. Pickle is really quick in programming and supports nearly all Microchip PIC mcus. It supports both high voltage and low voltage...

Re: /etc/inittab no longer present in Raspbian Jessie?

Thanks diederik.
But this does not work in Raspbian Jessie with systemd.
I have already tried some combinations like
console=ttyAMA0,9600 kgdboc=ttyAMA0,9600 console=tty1
console=ttyAMA0,9600 kgdboc=tty1 console=tty1

But kernel messages are still on both tty1 and ttyAMA0 :-(

Re: /etc/inittab no longer present in Raspbian Jessie?

Hello.
The same question - Can anyone tell how to change baudrate for [email protected]
I do not want to have kernel messages on ttyAMA0, but I want to have serial terminal connected via ttyAMA0 with 9600kbit speed.
Thanks

Re: Raspberry Pi PIC Programmer using GPIO

Hi DaveSemm. rpp-tlc is based on Heldon's rpp code and it expects INHX16 format of HEX file. If you compile ASM on Raspberry using gpasm, please use -a INHX16 option to obtain right format for rpp. There are more HEX file formats (INHX8, 16, 32) but rpp supports only INHX16 format. Hope this will so...

Re: Raspberry Pi PIC Programmer using GPIO

Hi NVK. I was under the impression that all models/versions of PI maintained the same GPIO PINOUT up-to PIN No 26 and hence no modification was required. Pinout on 26 pin header is the same in all revisions (except for the very first B model rev. 1.0). But my code in 0.3 version uses GPIO 28,29,30,3...

Re: Raspberry Pi PIC Programmer using GPIO

Hi NVK. I can comment this: device _id = 0x0000 Error : Unsupported device or programmer not connected and the funny thing in this case is that the Pi B+ hangs up and stops responding and I need to reboot. This looks to me that you have not modified GPIO ports. My version 0.3 at http://mujweb.cz/tlc...

Re: The Raspberry Pi Model B+ Q&A thread

B+ audio enhancement... I have tested B+ audio (via analog output) and yes, personally, the reproduction itself sounds a bit more real and rich than it is at B or A models. And default output level is aprox 3db louder. Thanks for that enhancement. But I have found that there is some slight level of ...

Re: The Raspberry Pi Model B+ Q&A thread

Thanks a lot for your answers.
I'm glad it looks that I have only temporarily shutdowned Eth+USB chip.
Camera module has not been connected at the first boot (neither was Eth).
Just keyboard and mouse.

Re: The Raspberry Pi Model B+ Q&A thread

Hi all. I have a question about GPIO28 - GPIO31. I have used them on B and A models for my RTC and SMT temperature modules and rpp PIC programmer. When I migrated my SD to B+ uSD I forgot to disable RTC routine and get B+ USB ports OFF at the end of boot because of that. After that I disabled it and...

Re: Raspberry Pi PIC Programmer using GPIO

Valter, thanks for your investigation and prepared line for 16F886. It will speed up my work. For 16F88x family there...

Re: Raspberry Pi PIC Programmer using GPIO

Hi Holden.
Ok. I renamed my modification of your rpp to rpp-tlc.
I was not sure if I can do this or not, so thank you for this hint.
And yes, there are the informations in README file which you mentioned above.
Thanks,
Tomas

Re: Raspberry Pi PIC Programmer using GPIO

Hi.
I have finished adding full support for 16F87xA chip family and released 0.2 version. I have successfully tested this version of rpp with chips 12F675, 16F627A, 16F877A.
Modified source and circuit (including two LEDs) can be found at: http://www.volny.cz/tlc/rpp/

Re: Raspberry Pi PIC Programmer using GPIO

Hi all. I have successfully tested my modified code with 12F675 chip. Including preserve or overwrite OSCCAL and BG bits. And read the 16F877A chip - programing it is a little bit different from 16F877 chip. I will add write and erase support for 16F87xA chip family soon. Modified source and circuit...

Re: Raspberry Pi PIC Programmer using GPIO

Hi Holden, I tried without the led's. Previously I also had not connected capacitors across the power supply, I did that this time around. Running sudo ./rpp still returns the same Error: unknown device or programmer not connected. I once again connected led's to each of the outs, to check that the...

So I have only tested read the whole chip operation a...
