Dangerous Prototypes

This is the firmware v5.4 development thread. I don't have a major todo list for v5.4.

*Selectable CS?
*I2C clock stretching?

Time for me to add some things :) It is been a while since I added code to the BP..

[s:]- sending partial bytes in raw2wire and raw3wire (it won't make sense for bytewise protocols)[/s:]
- history and commandline editting? (need to look very wel into source if it is doable, can't promise anything)

As always subject to change ;)

Nice commit :)

I just checked in rev [s:]442[/s:] 443.

- added partial read/write (less then 8 bits)
- added lsb/msb swap to send string
- fixed several minor bugs.
- compacted the infoscreen

I made a small goofup by reverting to much. rev 443 should be ok now.

partial read/write is invoked with adding ;[numbits] this is a persistent setting untill it is set again or the mode is exitted.

I'm sorry not to double check. I reverted raw2wire (because I thought i had nothing done her) but i shouldn't.

I left the CS for you :P

This is really nice.

Does it make sense to clear the unused bits (0x01;2) or show the binary value (0b01) of partial writes?

I'm going to update the LCD library to the new adapter now. (picture attached)

---

It would make sense to clear the unused bits, but the lsb/msb setting making a bit difficult (0x55 -> 0x40). I'll look into it.

I prefer to display the numbers as the user chooses.

Got the new adapter working. It's SOOO much faster than the old one. The a whole screen refresh is instant. With the v1 you could watch each character pop up on the screen.

I didn;t make it multi-adapter compatible. I don;t think the v1 adapter has a large user base, and we save a bit of room by only doing the SPI adapter. The new adapter doesn't support reads, so all read stuff was removed.

I'm going to get a quote on this now to see how much cheaper it is than the v1.

I did notice that the macros don't consume the trailing value properly, they always use the default. The trailing value is interpreted as a value to write. Everything looked fine, I'm not sure why this happens. I added the 80 character default to both 6 and 7 for now, but that doesn't help much with 4.

I'll upload this code and a new nightly now.

---

I'm pleased with the current state of the RC, is there anything else you'd like to get in before a release? I'll prepare one for tomorrow.

if you add an extra space after it?

(6) 80

I remember that code is a bit messy (the macro handler in procmenu.c together with the macro in lcd.c).

Shall I add userdefinable CS (:D) and partial writes?

0x55;2
write 0x01;2

I've been working on the PIC programmer buffer, and I could not figure out why nothing worked. It turns out numbits is initialized to 09. I added a =8 in bpinit and to the binmode I was working on. I think the buffer is really going to speed things up. I'm going to try to implement it for reads and writes tonight.

I'll get my new bulk commands tested and rolled into 5.4 too. The 18F version is done, it erases, programs, and verifies a 18F24J50 in 19.2seconds. That's a huge improvement over the previous method that

Cool!

(looks like you press post too early ;) I'm wondering how long it used to take :D)

Minutes :)

I didn't change the printing of partial bytes (yet). I'm planning reworking on that later on.

I just updated the svn with a minor update. It displays the settings in a simular way when setting the mode and parameters from the commandline:

R3W (spd csl hiz)=( 0 1 0 )

you can (re)view this settings with the 'i' command:

Not a very big change for the user, but it helps us to review the settings easier in case of trouble. The 'i' command now returns everything about the current settings.

I just noticed we added lots of new commands, but didn't update the help screen...

So I just comitted rev 453 with a new help screen (and proper revisionnumber in base.h ;))

I'm prepping this now. Thanks for the post, it's a huge help :)

I'll leave the part about the PIC programmer in, but unfortunately I've already changed stuff for it that is not in the v5.4 release ;)

I had to make a new compile for v1a, so I also recompiled v3 with the latest PIC programming extensions. Packaged and posted. Unstickied.
