Posted on December 08, 2013 at 15:56 Hello, I'm using CooCox IDE. I have problem with debugging in RAM and USART communication on STM32F4-Discovery. When I load my program to FLASH all works correctly , data transmit and LEDs on PD12-PD15 switch on ...
Posted on December 04, 2013 at 12:23Hi guys, I have to do a RAM check routine that performs Class-B controls on pre-assigned (probably all RAM) memory block. The first doubt that rise is : if I allocate the memory statically I can't free it (or rele...
Posted on November 07, 2013 at 19:02 Hi, I am currently stuck with stlink v2 and ITM trace on a STM32F103RB. I am using CMSIS debug support by simply calling ITM_SendChar(). This is the only trace specific code than I am using. I...
Posted on December 04, 2013 at 22:45I am attempting to get an STM32F4 to receive data in Master mode. I am getting a problem where the RXNE interrupt is never tripped.*Should this work, even if you have MISO tied to GND or 3.3V?*Do I need to do anyt...
Posted on December 03, 2013 at 23:55Hi, I'm experiencing an odd problem on the STM32F103RF where I get a hard fault UNDEFINSTR on return from WFI in DEEPSLEEP. Here's a summary of my observations: 1. The hardfault occurs attempting to execute code ...
Posted on December 05, 2013 at 15:02I have an application that requires both of the SPI interfaces running as masters. The code currently has SPI1 up and running. I have then copied the setup function calls and updated them to configure SPI2 (taking...
