Posted on February 23, 2016 at 07:27Hello, I am using a STM32F302RE custom made board. I am expecting my board to receive and transmit messages to and from controller, but I am not expecting the codes to flow to CAN_SCE handler. How can I prevent my...
Posted on February 23, 2016 at 06:48I use stm32f407zg and stemwin library and freertos.when I want load BMP , my microcontroller gose to HardFault after put some pixel on lcd( about half or less).FRESULT resultBMP;unsigned char _acBuffer[4096];FIL *...
Posted on January 23, 2016 at 13:04I am using ST-Link V2 to flash to STM32F747, It was successful. However, after sometimes change the code IAR pop-up below warnings: Warning: Write failed (CPU data abort) at Memory address 0x2001EF98 Warning: Wri...
Posted on February 23, 2016 at 05:31For all those planning to use ST STM 32F407 micro controller in there next design feel free to use the application hosted at to create free schematic designs. First a brief about the application 1. User enters P...
Posted on February 22, 2016 at 22:18Hi, I'm very new to STM32 family and I've been struggling for the past few days getting the HID device working the way I'd like it to.Basically, I'd like to create a custom device which would send 4 float values (...
Posted on February 21, 2016 at 10:44Hello all users, this is my first post on this forum. I'm new to STM microcontrollers and I have bought XCore407I board. I have got STM32L0 DISCOVERY board with debugg connector CN5, whitch can be use to programm...
Posted on February 22, 2016 at 11:18Hi, I want to learn that will ST release the standard peripheral library for Cortex M7 based MCUs? Because, the HAL libraries have some bugs (when I read anything about hal drivers in the forum, there is at least ...
Posted on February 22, 2016 at 12:26Hallo, I have a question to the STM32F103 (high-density device): After using bxCAN (sending, receiving, using filters, ...) I want to set the CAN-controller in the initial state (as far it is possible without a ha...
Posted on February 11, 2016 at 15:25Hi. I try to test emWin example – MEMDEV_AttitudeIndicator.c. To be able to run it 1024 * 700 bytes of memory are required. I took HelloWorld StemWin example as a starting point. When I try to increase the necessa...
Posted on February 22, 2016 at 10:24I copied the CS43L22's schematic design from STM32F4-DISCOVERY. There is only 1 point different in my circuit (a mistake during design) that is VP, VL is 3.3V instead of 3V like STM32F4-DISCOVERY. As per the datas...
