Can anyone provide a company name which provides
*customer* relationship similar to Microchip? I get a
distinct feeling that in the ARM world there isn't a
company geared to *small* volume markets. Responsive
e-mails to support and questions WOULD be a good
indication on the company's attitude towards the
customer. Any positive feedback on the ARM
manufacturers?
