ChibiOS Free Embedded RTOS

Use cobs encoding for frames. That will allow you to use DMA in receive mode without having to constantly poll/scan the DMA buffer if you have received a frame or not. Set receive DMA length to maximum frame size, and use the character match interrupt set to the 0 byte (COBS framing character) to ...

Sure - or wherever you think is suitable. FYI, updated my post above.

How about including something like this in ChibiOS as a helper:


/*
* Macro to declare a cache-aligned buffer
* Parameters:
* T - The data type of the buffer elements
* N - The number of elements in the buffer
* name - The name of the buffer
*/
#define DECL_CACHE_BUFFER(T, N, name ...

Has this been addressed? If so, in what versions?

Giovanni wrote:Hi,

Are you sure? the variable "cr2" already contains ADC_CR2_SWSTART, it should work as is.

Giovanni

You're right . Sorry for the bother

See adc_lld_start_conversion:

/* The start method is different depending if HW or SW triggered, the
start is performed using the method specified in the CR2 configuration.*/
if ((cr2 & ADC_CR2_SWSTART) != 0) {
/* Initializing CR2 while keeping ADC_CR2_SWSTART at zero.*/

Should be 100MHz

There should be a space between CSRC and CPPSRC.
