Measurement 2000-08-19 - - Posted by: Jeff Frohwein It is a 32 Channel, 40Mhz, fully PC controlled TTL/CMOS logic analyser with internal/external triggering and trigger delay. Internal triggering is fully maskable (High/Low/Don't Care) on all 32 channels.

Serial peripheral interface block diagram. The ST7FOX features Flash memory with byte-by-byte In-Circuit Programming (ICP) and In.

For extracting the definition, all the ODBC environment variables must be set to the correct path. The file is provided by Informatica and accepts the above mentioned parameters and tries to establish the connectivity to the database/data source as defined for the DSN. The definition for the DSN is provided in the odbc.ini file. To set the environment variables, refer to the More Information section. The following example uses ssgodbc.linux64, which is the 64-bit Linux version. This is a binary file, which runs to test ODBC connectivity. Malenjkaya sborka xp.

I used these in order to come up with this circuit.

It can only program 5V only memory so it can't program EPROMs or some EEPROMS. It's designed to be simple & inexpensive rather than a program-everything circuit. Why use EPROMs anyway? You need special equipment to erase them and it takes 20 minutes to do it. THESE PLANS ARE OFFERED 'AS IS'.

TOO MANY REQUESTS ARE RECEIVED TO ANSWER THEM ALL. 2001-07-09 - - Posted by: Jeff Frohwein This version of the flash programmer by Sshua is optimized for 29F040 (and similar) flash chips. On one computer, it took more than 15 minutes to write 512Kb to a 29F040.

Replacing the 74HC590 (binary counters) by 74HC595 (shift registers) on the address bus reduced this to 3 minutes. It's now a little slower than before for other eeproms. THESE PLANS ARE OFFERED 'AS IS'. DO NOT ASK FOR HELP GETTING IT TO WORK OR FOR MORE INFO.
