Creator Version:4.1

Device : 5LP

Attachments: PNG image of  C code snip

I iterate through a long loop and transmit a 72 character array over RS-232 if the host computer has requested an array readout.

At first, I used all 4 bytes of my hardware-only FIFO each time and then verified that the FIFO was empty using line 503 before putting 4 more bytes into the array. See attached code snip.. It didn't work - only 40 bytes made it out over RS-232 to the HOST computer (I verified that only 40 bytes were being sent using a scope).

I then commented out lines 505-507 and changed line 508 to increment the index by one instead of 4. Now it works - All 72 bytes are sent correctly.

What did I do wrong with my original attempt? 

Thanks,

hello cypress community, this is my first post here, i hope that someone can help me.

i forgot my psoc 4 cy8ckit-042-ble connected to the pc during the windows update and now PSoC creator can't find it.

in the device manager of windows i can find my PSoC board but i can't program it because the software don't find it.

i use a psoc 4 cy8ckit-042-ble. when i connect the board to the usb port the led turn on for few second and after turn off, such as the board isn't connected.

scuse me for my english, thanks to all and good work!

edit

in the device manager i find "kitprog programmer" and "kitprog uart" in the group of "other device" with an another  called "unknown device", all three icons show a yellow triangle with this symbol "!" inside.

Hi,

We are using PSoC 5LP and also using the SPRINTF function in the firmware.

This product uses μItron compliant RTOS.

Does the sprintf function in GCC support multitasking?

The current development environment is as follows.
-- PSoc Creator 4.2
-- ARM GCC 5.4-2016-q2-update
-- Linker settings
-- Use Newlib-nano: True
-- Use Newlib-nano Float Formatting: True

We think that sprintf may be causing problems due to simultaneous access from multiple tasks.

So I'm trying to use re-entrant "_sprintf_r".
However, the _reent structure must be defined, and the size of this structure is large and memory overflows.

Looking at the GCC document, it is written that if you define "_REENT_SMALL", the size will be reduced.
However, We don't know how to specify it.

Do you know how to define "_REENT_SMALL" ?

Regards,

We are using the PSOC 4 in our application and it has Boot loader and Boot loadable application both.

I have loaded the boot loader through MiniProg 3 and boot loadable application with the help of Boot loader Host. Both application were loaded successfully.

When I am trying to debug the boot loadable application through MiniProg 3 kit available with us, It doesn't allow us to do so.

How can I debug my boot loadable application??

Please let us know the steps to debug the boot loadable application.

Thanks.

I want to install Psoc creator4.2 and CCGx power sdk 3.3 on win7. But have the problem. Who help me. Thanks.

Hello,

In creator version 4.2, Cy_boot 5.8 cannot compile on certain PCs.

In this case, on the "Update Components" Cy_boot version looks "5.8 downloadable".

Why?

Best regards,

The static_assert macro appears to work however the IDE reports a warning of an implicit declaration. This does not occur in other tool chains, the Keil IDE editor actually evaluates the assert and generates an error warning during edit if something is changed that causes the static_assert to fail. Is there a way to at least turn off all warnings from static_assert?
