|
* @brief Creates either an oscilloscope or a logic analyzer
|
|
* @details TExaS is an oscilloscope or a logic analyzer, sampling at 10 kHz<br>
|
|
* - to create an 8-bit analog oscilloscope
|
|
* -# set adc12 to either ADC0 or ADC1
|
|
* -# set channel to 0 to 7
|
|
* -# scope ISR is 11 instructions, 1.5us, 1.5% overhead
|
|
* - to create a 7-bit digital logic analyzer
|
|
* -# set adc12 to 0, channel doesn't not matter
|
|
* -# create a function to read any 7-bit digital measurement, add bit7=1
|
|
* -# pass that function into TExaS_Init
|
|
*
|
|
* @note Works at 32MHz or 40MHz or 80 MHz
|
|
|
|
* @version ECE319K v1.0
