Jingtai, Have you tried stepping through the ISR (cla1Isr7()) ? This is where the ADC result is copied to the AdcBuf. It isn't clear if it is the project or if it is the hardware. Here is what I see in...

Hi CB1, may the DMA of the TIVA TM4C1294 has a limit to transfer 1024 items in one request, as I have found that out by using DMA with QSPI-Flash on the same MCU. Otherwise the DMA is delivering biased...

Bruce, No, there is nothing connected to the P4.2 pin when I get P4IN = 4, but I know its reading the pin, because when I tie the pin to ground, I get a reading of 0. Here's a picture of my board when...

Lori, Is this set correct? After setting the breakpoint the memory data doesn't change. The demo application of Launchpad runs regularly. It seems the hardware is not out of order. Regards, Jingtai

There is no 1-wire peripheral on the TM4C123GH6PZ device like there is on the TM4C129XKCZAD device, but it can be emulated with a UART. You would need to tie the UnTx and UnRx pins together and then...

The one that I am trying to address with this test is a TI HDC2010. It's ADDR signal is tied to ground so I expect its address to be 0x40. You are absolutely correct that I had made an error on the...

Jingtai, I assume you tried to start a task using the "run / resume" button. If the CLA is idle then this will not work. A task is only started by a trigger from a peripheral or from forcing a trigger...

Rahul, Do you use TI TMS570LC4357 Launch pad (a red board) or your own hardware with this chip? The launch pad doesn't need external power supply, we typically use the micro B USB cable to connect it...

Jingtai, You have tried to set a breakpoint on the function prototype. You will need to set it in the ISR code itself. Then step through the code and see what is being read by the ADC. I suspect...

Hi Erwin, No, you can't use GPIO18_X2 as a GPIO if X1 is being used. To use GPIO18_X2 as a GPIO, you will need to install an external 1k pull-down on X1.
