gnss modules and ATtiny chips #215

Closed hoka83 closed 3 months ago

hoka83 commented 3 months ago

Are GNSS modules for example "UBLOX MAX-M10" familiar with ATtiny chips like ATtiny1616 ?

PaulZC commented 3 months ago

Hello Mahmoud (@hoka83 ),

Are you asking if the u-blox MAX-M10 module will work with an ATtiny1616? Or are you asking if this library will run on ATtiny1616?

Best wishes, Paul

yes paul, is it going to work?

Hello Mahmoud (@hoka83 ),

There are a few parts to your question:

  1. Does ATtiny1616 have an I2C interface, or a UART?
  2. This is an Arduino library. Is there Arduino support - an Arduino Board package - for the ATtiny1616?
  3. Does it have enough memory, both Flash and RAM?

Looking at the Microchip product page:

It has I2C and USART. The USART can (probably) be configured as a standard UART.

Spence Konde (@SpenceKonde)'s megaTinyCore supports the ATtiny1616.

It has 16kB of Flash and 2kB of RAM. If I compile one of the library examples for the ATtiny1616 (with Optiboot), it needs approximately 30kB of program space and 1kB of RAM. I see the error region text overflowed by 17027 bytes. So, no, it will not run on the ATtiny1616...

This is a big complex library. There are much simpler u-blox GNSS (UBX) libraries that may meet your needs.

Best wishes, Paul

Is it possible to run this library on ATtiny 1616 by adding external flash memory though? , and where can i find those simpler u-blox GNSS (UBX) libraries?
