Re: ADC Read Two Separate Channels

Well it turned out to not be the ADC's causing the problem. I was using the GPT with polled delay as I need a 10us delay in one of the threads and this was causing the problem. I did try the halPolledDelay but I get a "Undefined reference" error. I am using chibios 3.0 has it been implemen...

ADC Read Two Separate Channels

Hello, What I am trying to do is read two adc channels IN11 and IN15. I want to read them separately. Each one reads in its own thread and so far I am using ADCD1 and ADCD2. My problem is when using the two ADCD's it appears to be resource hungry as my code stops when trying to read the two at the s...

Re: stm32f4 SDIO setup

Well I think you are right it must be my interface as I switched to the spi interface I had on the back of my LCD and it worked perfectly I have ordered a prebuilt sdio interface I will wait for it to arrive and try again.
Thank you for all your help.

ADC Result

Hello,
I have been working with the testhal stm32 adc example and I would like to display the result first as a int so I could do some math then as a string so I could display the result on my LCD using ugfx any hints on how to do this would be appreciated.
Thank You.

Re: stm32f4 SDIO setup

This is my board.h I think it is correct..
I think that I do get a responce as it hits this..
*resp = SDIO->RESP1;
HAL_SUCCESS;
Then cannot detect card..

Re: stm32f4 SDIO setup

I also have long wires connecting the sd could that be a problem?
