Adapters for in-system programming

Top  Previous  Next

The adapters.chm file includes short descriptions of the Phyton programming adapters for in-system programming (e.g. the programming in the user's equipment) and their wiring diagrams the schematic of connecting the adapter cables to the target. The cable adapters may have 10 to 20 pin headers to be connected to the pins or complimentary connectors installed in the user's equipment. The pin connection is specific for certain target devices. The connection diagrams are presented in a table form, where the columns (from the left to right) represent:

 

1st column

- Pin numbers of the cable adapter header inputs and outputs

2nd column

- Signals of the target device to be connected

 

As an example see below a schematic of connecting a 10-pin header BH-10 of the Phyton AE-ISP-U1 cable adapter to the Zilog Z8Fxxx microcontroller for in-system programming.

As you can see here not all the BH10 lines should be necessarily used. Only five signals are required for programming this device and only two of them are used for sending the the programming signals into the chip - RESET and DBG. The diagrams in the adapters.chm file use the mnemonic of signal from the device manufacturers' data sheets.
