Posted on March 10, 2015 at 19:09The definition of the osMailQDef macro is incorrect in cmsis_os.h; it is missing a semicolon. Here is the original version: #if defined (osObjectsExternal) // object is external #define osMailQDef(name, queue_sz, ty...
Posted on March 29, 2014 at 19:13Dear All,I would like to upgrade / update the STM32F429 firmware using a USB Key.I have found one application note, but I have not found any working example.Does anyone have some working example or some advise?Let me...
Posted on March 11, 2015 at 13:20 Hi everyone, I am trying to interface a linear CMOS image sensor by Hamamatsu (S9226-03) with a STM32L1 discovery board, and seek a bit of guidance on how exactly to accomplish that in a suitable way, since I...
Posted on December 19, 2014 at 22:48Hi,I am new to programming ST microcontrollers, and I am trying to get a demo tcpecho application running on my custom hardware. We are using an STM32F407. I notice that all the examples seem to use FreeRTOS and...
Posted on March 10, 2015 at 11:21Hi All,I'm on the tail end of a large development for an stm32 using gcc and openocd. As I add more code and bitmaps (for the LCD) I'm finding the load times getting rather long, mainly due to the bitmaps.I'd therefo...
Posted on March 10, 2015 at 14:57Hi,Is there a way to determine which MCU is being used on a board? We are developing software for an STM32F4 and some of our tools are using the 407 and others are using a 429. I would like to know when our code is...
Posted on March 10, 2015 at 22:16Hi,I'm using ADC and DMA. For learning purposes no interrupts, just polling LIFR. Staring conversion with ADC_CR2_SWSTART. As soon as TCIF is set, I'm writing 1 to ALL flags to LIFCR (LIFR becomes 0) then re-enablin...
Posted on March 10, 2015 at 18:19Hi,I have a legacy boot loader that was developed on an STM32F407. There is a line of code that computes the JumpAddress before it jumps to the main application. The line is: JumpAddress = *(__IO uint32_t *)(vec...
