Posted on April 20, 2015 at 19:36I'm migrating from PIC32s, so bear with me please. I'm trying to get up to speed on the STM32 using the Cube examples in EWARM. I'll try to keep this simple (I apologize, I don't know the syntax for code tags in th...
Posted on April 20, 2015 at 20:36 I am currently have intermittent issue where I am getting stuck in ''void USB_HP_CAN_TX_IRQHandler(void)'', Everything works well from minutes to hours then I notice my CAN traffic stops, currently I TX one mess...
Posted on April 20, 2015 at 10:33Hi, i have an external GPS signal that delivers seconds pulses (a short pulse every second). My goal is to count seconds in SW and trigger some actions every X seconds. Question a) I intend to use EXTI interrupt on e...
Posted on April 20, 2015 at 10:50HelloAccording to the page 18 of the ov2640 datasheet(version 1.6), device slave address is 0x60 for write and 0x61 for read, but in the camera_to_usbdisk project, only the write address is defined and used for both ...
Posted on April 17, 2015 at 17:51Hello.I have Using One of the example Program that port UCOS on STM32F4 Devices.I have One problem. When I activate Timer in one the tasks, The Timer is Working in a right way(example is on the blinking LED). but i w...
Posted on April 08, 2015 at 13:07Hi all,I�m designing a STM32F107VCT based embedded system. Unfortunately I�ve several problems with this part. For example the part wasn�t program correctly (Verification failed), and when I removed and soldered anot...
Posted on April 03, 2015 at 20:02How to find out APB1 clock frequency? I want to know TIM2 clock, which is connected to APB1. I use STM32F103 and standard peripheral library.Thank you.
Posted on April 18, 2015 at 06:47Hello,I have read the datasheet of stm32f407 about the DAC output range. When buffer on, the min DAC_OUT is 0.2V and max DAC_OUT is VDDA-0.2V.However, I get 0.069V at 0x000 and 3.272V at 0xfff rather than 0.2V and 3....
Posted on April 18, 2015 at 10:08Hello,I'm running an Cube project with FreeRTOS, with iWDT enabled, on STM32L1 and debugging on IAR.iWDT is being cleared in its own thread, with the same priority as the other threads.No thread is a blocking thread....
