TNT4882 and microcontroller

[nathanael loiseau]

Does anybody have informations on programming TNT4882 in microcontroller environnement. The application note concerning TNT4882 and 8051 is not very helpful for me.
Thanks in advance

Hi,

What kind of information are you looking for?. If you describe your application we might able to provide more detailed information.

Hello,

I want to use the TNT4882 in a 68HC11 environment. I found an example with 68HC11 and NAT9914 in AN110 which seems very helpful. However, when I compare the NAT9914 and TNT4882, registers are very different and I don't see very well when I should make each initialisations described in the TNT4882 manual.

I wanted to use the TNT4822 in One Chip Mode. It may be a bad idea ? Is there any way to download the example program of the AN110 to use it at a base ? Is there any guidelines to adapt a program from Nat9914 to TNT4882 ? Is there an example program for TNT4882 and 68HC11 (the programs in ESP-488TL kit seems very complicated to adapt for microcontroller)? The kind of program I am looking for is not about self test (like in AN077 with
8051) but "how to make data exchange on GPIB" (with interrupts if possible)?

Many thanks for your help.

Hi Nathanel,

If you are making a new desing we recommend using the TNT4882 in one chip since it gives you access to the advanced features of the chip, such as the FIFO. In any case you can also use the chip in 7210 or 9914 compatible mode. Actually the one chip mode is a superset of the 7210 mode.

There are a couple of tutorial on using the TNT4882 with a couple of processors (AN77 and AN73).

The ESP code provides you with a complete driver to use the TNT4882. You might want to check the ESP-488TL Software Reference Manual for TNT4882 to see how it works?. I guess that the problem of using the ESP for a given microcontroller depends if there is a C compiler for that uController.
