Posted on May 18, 2015 at 19:26Hello First of all, congratulation for the power efficiency of the ''new'' STM32F411, at low speed it's actually more efficient than a STM32F0, impressive. But I'm missing one important feature, it hasn't touch sensor ...
Posted on July 07, 2016 at 02:54Hi,I have one nucleoF411+IKS01A1 kit.I follow the steps of IKS01A1 quick start guides(http://www.st.com/content/ccc/resource/sales_and_marketing/presentation/product_presentation/84/4d/95/53/c4/91/4b/97/x-nucleo-iks01...
Posted on July 07, 2016 at 04:21I am looking for some help on completing a schematic whereas I am driving several LEDs with a shift register.I am having trouble finding where / how I should be connecting the CLK / SDI / LE/DM1, ~OE/~DM2 pins to the ...
Posted on July 07, 2016 at 10:38 Hi I use EXTI for trigger ADC for stm32f RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE); /* DMA1 Channel1 Configuration ----------------------------------------------*/ DMA_DeInit(DMA1_Channel1); DM...
Posted on July 06, 2016 at 23:19I have been programming an STM32f103, to get used to ARM (Olimexino board - don't laugh).I was advancing pretty well, had the GPIO working, SysTick interrupting and a basic time-banding system working.Then for some re...
Posted on July 05, 2016 at 22:09I am trying to set up direct memory access for ADC1. I have already configured direct memory access for ADC3 using an example I found here: This works for ADC 3, but when I try to change the parameters to set up ADC ...
Posted on June 29, 2016 at 22:40I am building a board using this MCU and I'm wondering where I can get some information on the USB schematics. Reading the data sheet somewhat helped, but didn't exactly answer my question. I would like the ability to...
Posted on July 07, 2016 at 16:46Hi How can I getting the source code of STEVAL-ISA147V2 ? Is there any body to help me for getting the source code? The core of this Digital switching power supply is STM32F334C8 . The topology of this D-SMPS is LLC...
Posted on July 06, 2016 at 14:48Hi, I am trying to generate analogue output using DMA. I have a taken http://vk.com/id62355309's cample code for testing. The output frequency is defined by#define OUT_FREQ 5000 // Output waveform frequency Above val...
Posted on July 06, 2016 at 16:12Hello all,Here my system specification:Device 1:- STM32L476ER/ZG- system clock = 4MHz- tick period = 100ms, (shortest irq possible, just pulling data)- usart- Transceiver MAX3485- modbus master- expected request = '':...
