I am planning to build a controller for a ceramic kiln.
I try to convert thermocouple mV with a TL501 dual slope converter that has
an accuracy of 0,05% FS. This converter is usually combined with and
controlled by a TL503 digital processor to obtain 41/2 digit BCD data.
Is there any experience (and code) for the control of this type of A/D
converters with PIC microcontrollers?
