I think that helped with the "idea" to read and write without desoldering, no errors, no bridges, fast. I took the idea to observe how other tools work and "Capitan crackers" "HCPI" and others, but improve in many ways, and I think mine is better. It helped me in this "Xmodder! and "Momis". But everyone can develop their own scheme.

I somewhat understand what you mean. But listen DK is one if not the best forum , the layout is great and you learn alot here. Alot I f members dont put the leg work in and dont know how to bait thier hook much less fish. They rather have others fish for them. You better understand and appreciate out craft when you know how a device works. Then expand on it. Incircuit UPa is one of the biggest topics here the solution can be a few diodes a rectifier bridge a few buffer caps resistors etc. Simple to extraordinary. Its a voltage drop circuit ..the answer to that is everywhere and can be done multiple ways. Some members teach other members by forcing them to use thier brains and that's a good thing because when u learn to fish u wont forget . Some members just out right refuse to help. Yes sharing is great.but doesn't always happen how many mem er in this same post have UPA scripts?? Have you shared them??

Yes and not, but 8 diodes, 1 diode = -0.3votts

oh I see, so if you take bender's scheme with 74hc and put diodes to vcc line to get 3v must be the same I think. Why do you change 74hc for octal buffer?

THANKS

[XmoDDeR]

it wasnt a good solution , had its faults

[toastedsiopao]

Mates!!!

I'll implement this on a non-schmitt trigger octal buffer.

[toastedsiopao]

I just don't agree putting a series of diodes going out of pin 9 of DB9 to put the logic level of the buffer at around 3.0V.

The voltage input HIGH and voltage input low of the buffers are affected by the Vcc change, so adjusting the Vcc of buffers at around 3.0V will cause errors when the UPA's output is set at 5.0V. So better adjust the voltage at the UPA side.

[claudio35]

It is a good solution 100% flawless. In circuit never a corrupt dump

version 1 and version 2, is same

[toastedsiopao]

what is the DIP switch for?

[toastedsiopao]

Ok, 1st guess.

For PIN 2 and 6 of the DB9 to become bidirectional.

[claudio35]

what is the DIP switch for?

It is to adjust the voltage, the lower voltage better reading

[toastedsiopao]

So the voltage to be lowered is from the PIN 9 of UPA.

So it will be 3.0V to the Vcc of the buffer and also 3.0V to the Vcc of the EEPROM, or Vcc of the buffer is directly from UPA, while the adjustable Vcc (via DIP switch) is for the eeprom only?

[toastedsiopao]

And how many voltage steps did you put? Thanks.

[toastedsiopao]

Schematic without the voltage adjustment.

[toastedsiopao]

Is the voltage dip adjustment after the buffer ic or before the buffer ic?

[roman_auto]

does someone sell this adapter to read in circuit ?

[toastedsiopao]

No one sells it, that is why I am making one and I am sharing it here.

Anyway, it is not as easy to assume that when we lower the voltage of the target with this buffer, it means already a good read of data, as we do not know the same parameters of UPA.

Here is the parameter for the sn74hc244.

I will try to read in-circuit this weekend by configuring UPA @ 3.3V, setting the buffer IC at 2.0V (target also at 2.0V) if there will be any error and of the writing is not also affected.

I dont think so...

[toastedsiopao]

If you want to do in circuit with almost a number of MCU, you can make another adapter that has a bidirectional single pin, you can adjust the direction by using dip switch or look for an IC that is capable of bidirectional communication automatically, or better program another microcontroller which does so.

Anyway, I am thinking of replacing the buffer with a microcontroller, LOL.

[toastedsiopao]

I got the issue now on the use of diodes on the target board, it is because the target board is trying to source excessive amount of current than the UPA board can provide to the target board, the effect is the UPA Vcc out at pin 9 of the DB9 goes down and the UPA Vcc auto detect error senses it and does not continue with programming or reading.

Anyway, I'll provide the schematic and layout of the ISP adapter later, with the additional diodes at pin 9.

[digimile]

hi
give a try using pin P2,P3,P5 and P9 and read write all ok..

[toastedsiopao]

I already tried the adapter, in circuit and on stand alone. It works, but some board requires lowering of target voltage due to loading. I designed another board with built in dip switch and diode, and another board without dip switch and diodes. But I also made another board containing nothing but dip switch and diodes lol.

Of course I can share it here if someone wants it.

[claudio35]

[Kermolek79]

your buffor only work correct when you set 3v3 in upa but without 4 your diodes

when set 5v with 4 your diodes is bad without 4 your diodes is ok
look http://www.nxp.com/documents/data_sheet/74HC_HCT244.pdf
look on page 1:
Inputs include clamp diodes
that enable the use of current limiting resistors to interface inputs to voltages in excess of
VCC .

page8:

VI input voltage max VCC

V input - 0.6V diode in structure hc244 go to TVCC this is problem !!!!!!!!!!!!!!!!!!!!!!!!

Remove 4 diodes and set voltage 3.3 or 5 in upa and will be work :)

[toastedsiopao]

Vcc is from UPA, TVCC is Vcc - diode setting.

TVCC is dependent on the DIP switch, it can be 0.7, 1.4, 2.1 or 2.8.

The use of diodes is to avoid the TARGET BOARD sourcing excessive current and therefore pulling Vcc (pin 9 of UPA) below limit.

The clamp diode use is for the 74HC244 accept excessive V input at the signal pins (quite not relevant here, as we know UPA signal max is around Vcc), and you need to put a series resistor just in case o use the clamp.

UPA functions w/ or without the diodes, as long as the target can accept the tolerable signal levels at give supply voltage.

So still you cannot answer directly if what will be the problem...

[Kermolek79]

For accept high voltage like VCC is need use specialized IC or level logic translator for signal ( when UPA send signal )
But make what you want

I can understand your point, but the power for the buffer ic comes from the upa not from the output of the diodes. The diode is for the target eeprom in the board.

Got a new design using a logic level converter.

The 7404 buffer and 74HC244, even the 74HC345 buffers will not work with I2C, so I doubt the ones posted here work well with I2C eeproms.

[captain crackers]

TROUBLESHOOTER As the UPA reads all supported micros in circuit (well at least mine does), what would be the point of it? Arthur.

[TR0UBLESH00TER]

Well , I meant to say without pin lifting ,it is a stressful operation for me ,but I think more training should help :hmmmm2:
The general ideea of the circuit (lowering voltages and increasing pin current ) is good ...today played with my unmodded UPA and see how a load of 10 mA (470ohms @ 5volts ) kill the the traffic on a 24cxx ,either SDA or SCL...

[mawar]

hi mate...upa original + in circuit adapters from " Arthur " can do...

[Zmann]

Modification on-the-board and maintaining the original nine-pin output possibily the effectiveness to most taget device.

If ones in doubt try HC11 on IAW 8P.xx in circuit with ori UPA !

[toastedsiopao]

The question is not on current sinking, how can you sink more current if you will not increase voltage. The issue on this one is how to power up the target MCU or the EEPROM without powering up all the components near it.

I found a FET that can do program eeproms and it is bi-directional, so there is a high probability that it can also do microcontrollers.

[Zmann]

All resistors for current limit in all signalling/control pins seem too high and can be considerably lower. But again the sinking capability of the drivers is still limited, that's the point that need correction too!

Let's say I want to read MC68HC05B16 mcu with upa usb 1.3 clone. But this time without soldering to make process a little faster.
Does it makes sense to even try to solder extending wires in between adapter board and actual plcc52 socket?

Also need to swap wires for socket pins because mcu will put in socket from the other side.
