UC3C2: DAC for internal routing to ADC does not exist. ??
I implemented the above Sequence to measure the internal References and Voltages. Its strage. In Detail: 1) Set the DAC Reference to VDD 2) Output somewhat around 0.2V 3) Set the...

UC3C2: DAC for internal routing to ADC does not exist. ??
Of course the negative inputs work. It is also possible to connect at least one positive and negativ input to the (ground-referenced) Ref-Voltage-Pin. This hardware workaround...

UC3C2: DAC for internal routing to ADC does not exist. ??
Not that i made some progress, but i am still at the problem. I tried all inputs for the negative side of the ADC.  The UC3C2xxx has a smaller package and less pins and...

UC3C2: DAC for internal routing to ADC does not exist. ??
So i looked further into this. I completed the self calibration for the DAC but i still have no luck with the internal signal DAC1_int. The datasheet for the Uc3C2256 (table 2-1,...

UC3C2: DAC for internal routing to ADC does not exist. ??
Its the basic operation: the maximum Ref-Voltage allowed is 3.5V at the ADC. If you want to digitize 0V-5V at the ADC-Input you set one input to VCC/2 which was planned to be done...

1us timer using TC on UC3B
Simply do the basic math. 1us period is what frequency? (f) Triggering and executing an interupt const how much cpu Cycles? (n) What is f*n ? (clk) Is clk...

Help with HMATRIX @ UC3B - DMAneeds to speed up.
Normally everything should be ok with this configuration. Try to use PDCA Channel 0 & 1 for SPI if this is a reason that causes serious problems if it hangs. E.g. The ABDAC...

YEEES! Great that someone else had that problem! Do you have measured some performance lacks after that modification? An interesting test would be memoryaccess and calculation...

C++ project
Ahh you are using the framework. The Framework is wirtten in C. Then you need to tell C++ that included functions are C-like name mangled. Its easy normally, but you need to be...

Just do it your self. Works exactly like C but the fileextensions are .cpp Did you try ANYTHING before this post?? What kind of problem do you expect? Hmmh.

Illegal Opcode when writing SDcard in RTC interrupt.
Your interpretation is correct. Polling issnt that hard normally. You program should have a while(1) loop somwhere where it stucks continously to execute the program. The while(1...
