The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on January 11, 2014 at 13:49Hi all,I want to detect a falling edge on external pinn let's say PD13 by hardware but without using the interrupt capability (using EXTI + NVIC).At first time I thought it is possible to do that using EXTI only by...
Posted on January 06, 2014 at 10:15Hi all,I'm trying to receive char using USART through interrupts but it seems doesn't work (it doesn't receive the interrupt when I prompt a char in the terminal).I use USB To RS232 TTL UART PL2303HX for connect st...
Posted on January 11, 2014 at 17:28HelloI am trying to implement indirect voltage measurement in a battery operated application.Our MCU supports VREF+ and VREF+ is derived from the battery voltage. Therefore - VREFINT must be used to extract VREF+.T...
Posted on January 12, 2014 at 21:00 Hello, i made reflow oven controller by using STM32F429i mcu with amoled and capacitive touchscreen. I get it display images correctly by using original stm32f429i-disco files, but i am having troubles to make cap...
Posted on January 11, 2014 at 19:31I've a small query about programming ADC in regular dual simultaneous mode. I'm using stmf4 discovery board.Though I've configured ADC1 channel 11(PC1) and ADC2 channel 12(PC2) in this mode using dma. But I've to c...
Posted on January 12, 2014 at 01:29I am using a STM32F4's internal CRC peripheralMy test sample data works against the code available at http://www.opensource.apple.com/source/xnu/xnu-1456.1.26/bsd/libkern/crc32.cSample data is { 0xA1, 0x11, 0xC0, 0...
Posted on January 11, 2014 at 12:51Hello everyone,I would be very gratefull if you help me with this or give me some idea. I have problem with STM32100RB USART module. It uses Cortex M3 and I am developing in Keil uvision.The USART uses hardware flo...
Posted on June 18, 2012 at 13:32I am using the STM32F4 family with Atollic TrueStudio and would like to use the CMIS DSP_Lib for my application. The STM32F4xx_DSP_StdPeriph_Lib_V1.0.1 directory as provided by ST does not appear to have pre-built ...
Posted on October 17, 2013 at 21:31 The code shipped in the FW library either says it's not implemented, or is in fact the code for the STM324x9I-EVAL with or without the name changed. The code was for Bank1 SDRAM at 0xC0000000, it will not work...
Posted on January 10, 2014 at 23:38I don't have one of the discovery boards (I know, I know ;), just a small stack of F205 chips. I'm breadboarding one up so I can get a handle around it, and having trouble identifying the minimum circuit needed for...
