Toying with ATTiny84 and SD card in Arduino IDE

As I mentioned in my previous post, I tossed in a SD card port for the TinySensor v1.1. I wanted to give it a live test and see if/how it works prior to submitting the PCB to the fab house. So I  did a breadboard setup as per TinySensor v1.1’s schematic (MCU+SD part only). Next, I decided…

The Tiny Sensor gets a SD card port

I had some space left on the TinySensor v1.0 PCB, plus I left myself few days to think before ordering the first batch, so I decided to throw in a SD card port. I didn’t want it to be anything fancy like the impossible to solder SMT card slots, so I decided to go for…

Flashing Arduino from SD card

Remote sketch uploading has been something I have long wanted for my projects. I can outline two major cases: 1) Remote flashing over TFTP – useful for remote locations where it won’t be convenient to go physically 2) Flashing from SD card – useful when you can provide firmware (compiled to .bin sketch) for downloading by end…
