you’re a CCS C programmer, a very good microSD card
driver comes as standard equipment with the CCS C
compiler package.
Add Your Mortar
All you need is a microcontroller that can drive a SPI
bus, along with a pair of USARTs. The first USART will
service the PmodGPS. The second USART port can be used
to feed a data radio. To measure the temperature, all you’ll
need is an ADC input port.
I’ve provided a microSD hardware circuit and access to
the microSD driver firmware. You also have GPS data
acquisition skeleton code and you have the code to process
the ENV-TMP’s temperature readings. All that’s left to do is
apply these tools to your modularobotic design. SV
