I would like to develop a specific driver on a FIM on a NS9210, under NET+OS 7. This driver will encode and decode radio frames.
I haven't found any detailed documentation about FIM but what I have understood is that 2 FIM are embedded on the NS9210 chip and com from Microchip IPs. I suppose they are 2 MCU with their own FMASH and RAM memories.
- 1st : question : where could we find the datasheet ? What are the FIM features (memories sizes, PLL configuration, ...). Is it possible to develop with Microchip assembler instruction set, and so which one ? PIC16, PIC18, ... ?
I seems that only 8 GPIO are available from FIM (GPIO0 to GPIO7)
- 2ns question : is it possible to use any of these GPIO for really general purpose (for example one to send a signal, another to receive a digital signal)
3rd question : how does the executable code is generated ? Can the code source be compiled and linked with ESP ?
Can it be debuugged wthrough JTAG interface ?
It seems that the executable can be generated in a C source file with a tool named genpicprog. Where can I find it and how to use it ?
Thanks for your reply.
