Posted on January 07, 2016 at 17:54Hello,I use STM32F4 discovery board connect to cmos digital camera OV7670, I know STM32F4 have DCMI which have capture image from camera and i have sent success image from camera to TFT 2.8 inch(DCMI -> FSMC though...
Posted on January 07, 2016 at 01:53I'm using a timer in PWM mode to create a clock source. I'd like to be able to reset that timer so that the TIM edges coincide with an external (asynchronous) source. If there is no edge on the external source, I...
Posted on January 06, 2016 at 20:35Hi,I would like to understand what development tools/environments are being used for STM32F4xx chips by professional developers.1. What is the most popular RTOS?2. What is the most popular IDE?3. Does anyone really...
Posted on January 05, 2016 at 09:58On STM32F0x2 (USB line) PA11 and PA12 are used for USB. However, the datasheet states these are supplied by VDDIO2 which can go down to 1.62V. So one cannot use the USB functionality when using the STM32 for logic ...
Posted on January 05, 2016 at 09:18Hello!!I test an access to eeprom by I2C Fastmode(polling) like following programs.But when writing a block to eeprom, it happens an I2C error.So I insert a delay time(1ms : _delay_ms(I2C_DLY)), and then it operat...
Posted on January 07, 2016 at 12:14Hi, similar (but different) issue to a previous posting of mine. I am seeing PA1 on an STM32F205 get driven low during standby after __WFI() I was expecting all GPIO to go Hi-Z during standby apart from the pins de...
