Posted on August 26, 2013 at 15:47Hi thereI'm still a bit confused about whether I have to connect the nRESET pin of the 10-pin Cortex Debug Connector to the NRST or the NJTRST pin of the STM32 in case of both JTAG and SWD connection. Could anyone t...
Posted on August 15, 2013 at 05:55Hello: Today , I want to capture the high-level length of input signal using TIM5 Channel 1 (PA.0) in chip (STM32F103ZET6)?but why program can not enter TIM5 interrupt service ? please help me ! I have attached ...
Posted on August 26, 2013 at 15:20 Hi , I am having a little bit of trouble configuring the audio codec (cirrus CS42L52) on the MCBSTM32F400 (stm32f407IG) evaluation board . I am trying to do a reset to the codec via the reset pin , but looking fro...
Posted on August 22, 2013 at 16:35Hello Everyone, I am using stm32f407 which is interfaced with 1MB of external RAM. Linker script is a simple one where it puts the data and bss section in external RAM. Regarding code execution I don;t have an issue...
Posted on August 25, 2013 at 14:46I'm new on STM32F407 and STM32F4xx DSP and Standard Peripherals Library. And now I've got some question.1) GPIO timingWhen I code GPIOF->BSRRH = 0x0100U; GPIOF->BSRRL = 0x0100U; GPIO...
Posted on August 24, 2013 at 18:41Hi there, If I setup both ADC1 and ADC2 in independent mode and set ADC1 to scan channels 1,2,3 using DMA and setup ADC2 for analog watchdog on channel 2 having different sampling times for channel 2 between the ...
Posted on August 23, 2013 at 15:59In my application I'm sampling a 50Hz voltage at 300Hz in a timer interrupt. My application is able to alter a part of the flash memory to save parameters. But during during flash write/erase activity the CPU stalls...
Posted on August 23, 2013 at 12:48Hello again, I have connected two STM32F2 via SPI1. The data will be transfered via a variable sized datablock. The first two bytes are a command (5 bit) and a length (11bit) information of the following block. Is i...
Posted on August 23, 2013 at 09:39I think ITM_SendChar is freezing my code when I don't have a debugger attachedWhen I do have an debugger attached, it works, and I can see my messagesBut when I don't, then the code doesn't get past the printingBut ...
Posted on February 07, 2013 at 06:15Hi guys !I'm just about to order but wanted to make sure first. I'm trying to get four stepping motors (bipolar) in daisy chain. I want to use the chain as it is said in AN3991 with the difference that I'll be use...
