ren24lv firmware

[cmitcham]

i am programming pics for the ren24lv driving dc ssrs for the first time, for another member, and i don't have the lv board to test with, so...

here is all i find on the ren24lv wiki page:


Firmware

All Renard Firmware is located Renard_Firmware This board REQUIRES the POSITIVE OUTPUT firmware option. Comment out the following line:

[ #define OUTPUT_NEGATIVE_TRUE] as follows;

[;; #define OUTPUT_NEGATIVE_TRUE]

sounded like the only change was sourcing rather than sinking outputs.

but comments in the firmware lead me to believe in addition to the above, that i need to change DC_build and CTR_LOCKOUT.

so here is what i'm going with. does this look right?


;; PWM_build can be either 0 or 1
#define PWM_build 1
;; DC_build can be either 0 or 1 (it should be 0 if PWM_build is 0)
#define DC_build 1

#define CLOCKRATE 18432000
#define BAUDRATE 57600

;; CTR_LOCKOUT should be 1 for the DC build, can be a somewhat larger number
;; for non-PWM or non-DC builds.

;; #define CTR_LOCKOUT 15
#define CTR_LOCKOUT 1

;; For positive_true outputs, remove the following define (normally, this
;; should be left in place).
;; #define OUTPUT_NEGATIVE_TRUE

thanks for any help.

Isnt the LV firmware located on Franks site?

[RichF]

Yes and it is available on Franks site and also in the wiki.

as usual, nothing is available at frank's site, or maybe it is my firewall here at work, but i don't think so. i can get to http://www.kostyun.com/, but all the links on that page show me an empty screen.

as i show above, the only firmware i find in the wiki is the standard renard .asm file. it does need some editing to work with dc ssrs, hence my questions...

repeating my guess for ren24lv changes:

1. comment out OUTPUT_NEGATIVE_TRUE line
2. change DC_build from 0 to 1
3. change CTR_LOCKOUT from 15 to 1
4. leave PWM_build set to 1

marble, i have your chips ready to mail, programmed with this guess, but i sure would love to hear from others if i have made the correct changes.

also, there are several similar but different paths through the wiki. if anyone knows the firmware i seek is in the wiki, please show me where.

thanks all!

That sounds correct - btw the Ren48LSD hex files in the File Library are identical to these settings.

[cmitcham]

ahh, the file library. it didn't occur to me to look there. thanks very much.

marble, the chips are in the mail :)
