It turned out Harmony3 has a function for such a scenario called SERCOM0_USART_WriteIsBusy(). My suspicion is that write buffer is not empty until much later and another write after the first one is...

Hi Salem,

The results are still the same - single output - for both of your suggestions.

Thanks for the help

Mr. stahta01 - excuse me if I am misspelling your name here.

What difference does it make if a cat chases mouse #1 or mouse #2 especially when they twins?????

Thanks to EVERYONE replied to my question. I appreciate your suggestions. You are awesome!

I admit that I assumed things in my original post hence the replies can only be speculative.

For a PIC32CM processor, I am trying to use the UART write function twice in a row. The project is built from Harmony3.

SERCOM1_USART_Write(char_array1, sizeof(char_array1));...

Thank you Sir Galahad for pointing to the posts.

Hello,

In a MPLABX 5.45 project for PIC32CM , any variable declared or used as char is flagged but the code still compiles successfully.
For example, in a file named UART.c, three of the char...

Thanks, flp1969. I will be testing it in the coming weeks.

"Is there a logical reason you do not read the manual on how to configure an Serial Communication Module to do SPI?"

Do you even understand the logic behind my question?

Hi flp1969 - thanks for your reply.

1. The connection between the two components is straight forward. I have done this many times, so no issues there. Additionally, I am not concerned about the...

Hello All,

I have had great luck in obtaining answers to my questions from this forum, so I though I might throw out this question, also.

Need to communicate with AD4000 using PIC32CM. AD has...

Thanks christop for explaining.

Hello,

I came across this decleration in one of the header files:

#define RTC_MODE0_INTENSET_CMP0_Pos _U_(8)

The process is clear to me, but being a novice programmer, my question...

Wow! Laserlight. Very well explained.

The compiler behaves exactly as you have suggested for the alternate uses of parenthesis:

#define LED_Off LED_Set() --- but now have to leave out the...

Hello,

I am working with PIC32CM controller using Harmony3 framework. Can someone explain the following use of the language:
