test program for the AT30TSE75X class
Dependencies: AT30TSE75x DevInterfaces I2Cinterfaces mbed
Fork of MCP4728test by
This is a program to use the AT30TSE752 with MBED . The program is used to test this device as temperature probes for the the SOLID project. It also is able to write to the ee-prom and is able to write protect the ee-prom and unprotect.
