1. /Program
2. /Program:noquest
3. /Program:noanyquest
/Close
this parameter has sense together with /Program parameter only, and
makes program to close automatically after device programming is
finished (no matter if operation was successful or no)
/Eprom_Flash_Autoselect[:xx]
forces automatic select EPROM or FLASH by ID when program is
starting or even if program is already running. xx means pins number
of device in ZIF (this time are valid 28 or 32 pins only) and it is
required just for older programmers without insertion test capability.
For others programmers is the value ignored.
Hardware
Due a large variety of parallel port types, a case may occur when the programmer cannot "get
concerted" with the PC. This problem may be shown as none communication between the PC
and the programmer, or by unreliable communication. If this behavior occur, try to connect
your programmer to some other PCs or other parallel ports near you.
If you find none solution, please document the situation, i.e., provide us an accurate
description of your PC configuration, including some other circumstances bearing on the
problem in question, and advise the manufacturer of your problem. Don’t forget please enter
of PC type, manufacturer, speed, operation system, resident programs; your parallel port I/O
manufacturer and type. Use please
Device problem report form for this purpose.
ISP (In-System Programming)
Definition
In-system programming allows programming and reprogramming of device positioned
inside the end system. Using a simple interface, the ISP programmer communicates serially
with the device, reprogramming nonvolatile memories on the chip. In-system programming
eliminates the physical removal of chips from the system. This will save time and money, both
during development in the lab, and when updating the software or parameters in the field.
Target device is the device (microcontroller, PLD, etc…), which is to be in-system
programmed.
Target system is the physical Printed Circuit Board (PCB), which contains the device to be
in-system programmed.
ISP programmer is programmer, which has in-system programming capability (for example
859, 866B, 844USB…).
General rules for in-system programming
We recommended respect following rules to avoid damage PC, ISP programmer, and target
device or target system:
•
Ensure common earth point for target system, ISP programmer and PC.
