(On discussion of still using IBM Thinkpad T43p with Pentium M)
They are some of the computers that don’t need a USB dongle thingy (unlike our modern laptops) to communicate with our microcontrollers because they have both a hardware COM port and a hardware LPT port.
Mainly for that. If we have a failed board or some sort (for example some kids might reverse polarity on the power pins and fry the onboard programmer) we would need one of the dinosaur computers. CSR bluetooth chips, too.
They (tech) put windows 7 on them. I was surprised since those machines don’t have much RAM, so the Windows Xp should be the (default) choice.
It’s really a … well, yeah. Because if you think about it, a microcontroller (a.k.a. mini all-in-one computer) is usually deployed in an “industrial” environment (e.g., in a touchscreen ice cream machine, or a dishwasher). They don’t really need the ability to interface with a computer (over USB).
So while I am all over Arduino leonardo or the Arduino Due for their direct-USB capability (so it can be programmed to be different USB devices, like a game controller), said capability isn’t needed if the intention is to put it in an ice cream machine (or a fridge). Hence the original board, Arduino Serial uses a Serial/COM port. As time goes on Serial/COM is faded away by Universal Serial Bus, and so a USB/Serial chip is put on the board and Arduino USB is born. The ATMega328p never have USB capability – in fact, the serial pin on the Uno (TX1,RX0) is connected to the USB to serial converter and used while programming because the 328p have only one serial for both programming and communication. More modern chips, as the ATMega32U4, have built-in USB capability, and the ARM3X8E have USB Host ability (in addition to the ability to act as a USB device)
CSR Bluetooth radio is somewhere in between, as the company seemingly went bankrupt or are …
Oh, they are bought by Qualcomm. ok. Maybe I should ask them for a Bluetooth module?
(being flooded by a massive wave of chips) Just what I was looking for.
