EEVblog #1144 - Padauk Programmer Reverse Engineering

[LovelyA72]

Stock depleting, be quick if you still wanna pick up some PMS150C!

[LovelyA72]

There's a new category on Padauk's website called PML series
There are some speculation that it might be a new series of low power (or even single cell battery?) MCU.

[spth]

Datasheets for the PML100 have been published. Looks like the L stands for "LED", not "low power", as the PML100 has "One set triple 11bit SuLED (Super LED) PWM generators and timers".
Though operating current at 1 MHz is also 50% lower than for the PMC150. And power save current (stopexe) is much lower than PMC150 (5 µA vs 400 µA). Power down current (stopsys) is slightly higher, though.

P.S.: Interestingly, despite the memory sizes covered by the pdk13 architecture, this is actually a pdk14 device, as we can see from the "ASM_INSTR SYM_85A" in PML100.INC.

The PFS172/173 series seems to be discontinued and no longer available. The follow up is the PFS122/123 series which only seems to have a 12bit ADC instead of the 8bit ADC. At least the PFS122 is available right now:

https://lcsc.com/search?q=pfs122

Will there be a support in easypdkprog too?

Those look particularly interesting - reading through the datasheet they have a "limited voltage programming mode" where it uses 5.0V volts only, which means a simpler programmer with no voltage shifting shenanigans could be doable.

Support can be added as soon as I can get hold of some ICs.

Those look particularly interesting - reading through the datasheet they have a "limited voltage programming mode" where it uses 5.0V volts only, which means a simpler programmer with no voltage shifting shenanigans could be doable.

In the development branch you can see already some devices (e.g. PFC151/PFC161/PFC154/PFS172/PFC232) which use limited voltage programing mode.

The main gist of limited voltage programing mode is that VPP is set to 0V during programing phase (only VDD of apx. 4.8V needs to be supplied).
However to activate the special programing mode you still need 2 different voltages for VDD and VPP where VDD < VPP-1.5V
So yes... this would make it possible to omit the DCDC booster, but setting variable output voltages for VDD and VPP is still a thing.

[jacola]

Hi JS, do i see this correct that you could have VDD switchable between 3.3V and 5V,
and to activate 'special programming mode' you could do VDD 3.3V, VPP 5V.
Then later set VDD to 5V ?
on-board switching between 3.3V and 5V, with a reasonably low current, could probably even be done with an analog switch ..

I would like to use padauks (PFC154,PFC232,PFS122) in multiple projects now. Ideally programmable in the board, by higher level micro.

Happy to support the development efforts not only with praise but also with material.

We will do a WS2812B output driver and an I2C software slave.

Thank You.

Now I have working write and read

I made BIN decoder.
Start decoding from configuration words (0x76 in BIN; "xdat", 4B len, 32B configuration words, 2048B data....)
Output: 1024W data, 16W config.

"ny_dec(buffer, 16+1024);"

Whoa! Is that a Nyquest flasher? Does this means that we can flash Nyquest NY8 with EasyPadaukProgrammer hardware?

Nyquest NY8A051H *.BIN decoder.
I'm not sure it's 100% correct, but it's a start.

Thank You.

Now I have working write and read

I made BIN decoder.
Start decoding from configuration words (0x76 in BIN; "xdat", 4B len, 32B configuration words, 2048B data....)
Output: 1024W data, 16W config.

"ny_dec(buffer, 16+1024);"

Does anyone know what is wrong in my attachment?

You don't read anything to decode.
You have to read BIN first (from 0x76).
"nop_bin" is xor table, not data to decode.

So, i got a first board with PFC154 working and its mostly in-circuit programmable with the lite-r1 (i interrupt the VDD pin for programming).

Now i am trying to do an efficient WS1812B driver, in assembler, and an i2c slave (interrupt driven) within SDCC framework.

So far so good.

I will help where i can answering questions.

Where is the activity regarding Nyquest suddenly coming from? I noticed you can now buy plenty of their devices very cheaply on LCSC. It looks like they are basically PIC clones? They are supported by SDCC?

Also, many Padauk devices are in stock again at normal prices! Most interesting is the PMS154C-S16, which is well supported by the OS toolchain.

[spth]

There have been a few new devices recently: the current Padauk IDE mentions a PFC887, there are datasheets for PFC440, PMS15B, PMB180, PGS134, PGS152. I've added some github fppa documentation repo today.

But I wonder if the instruction encoding used on PFC886 and PFC887 is really the same as other pdk16 devices: the .INC files call it SYM83B2, while for the older pdk16 devices, it is called SYM83A.

Hello together
I wanted to ask if the  PFC161 is supported by SDCC and the free pdk programmer at the time.

It is. easypdkprog added support in June 2021, SDCC has had support since spring 2019.
I'd still recommend to use a recent version of easypdkprog and a recent release (e.g. SDCC 4.2.0) of SDCC.

Thank you

Hello everybody,
  The EEVblog community has made the padauk programmer which I have and used it. I also have the 5S-I-S02B padauk provided emulator. For testing my programs I use this emulator using the IDE provided by padauk itself which supports mini c language.
   My question is, can I convert this mini-c programmed code to the ihex file supported by the freepdk programmer? If not I have to first check the code in emulator, then write the same code for sdcc compiler which does not feel good to me.
  The IC that I am working with is PMS171B which is OTP type and I can not reprogrammed it to fix any minor mistake for which I have to use emulator. I also tried converting the mini-c code into asm code and copy the code in sdcc compatible way using  "__asm" and end it. But during compilation it shows error. While converting mini-c to asm, some commands with "" will also appear which I removed.

something worth mentioning in the newer padauk IDE. They are using a key and response system for the customer service to unlock clients that can not connect to the internet. Might be a fun investigation if someone is interested. The way to access the unlock dialog is to run a fresh IDE without internet connection and click Help > News

Correct, they are PIC clones. Their NY8 C compiler uses a modified SDCC without following the GPL open source license by opening the source code of the modified tool chain.

So the new IDE is locked down? It really seems that Padauk is not appreciating the open market...

I am having a good time with the CH32V003. It's a minimal RISC-V (RV32EC) microcontroller that is only $0.10 and comes with an excellent free toolchain. Not to speak of an overabundance of periphery including DMA...

Ok, that explains. I saw references to the SDCC toolchain in their examples with a target called "ny8", that is not supported by the official SDCC. Annoying, and not something that should be supported.
