Posted on March 11, 2014 at 21:48I'd like to model if it's practical to drive an STM32 output into a transistor. I've got some Optimos 3 transistors with a 2.8v Vth:http://www.mouser.com/ds/2/196/BSC340N08NS3G_rev2.6-76670.pdfThe transistor would b...
Posted on March 11, 2014 at 02:34LD8 LED is ON (USB over-current) regardless to program. Furthermore receiving data by UART3 using pin PC11 is impossible, but with PD9 works fine. Earlier I had no problems, and now after connected the board to the c...
Posted on March 11, 2014 at 16:50Hello everybody,I'am trying to use analog watchdog on STM32F051K4 and I face some problems. I want to measure a pulse on PA0 (ADC_IN0) of 100us wide with an 1V amplitude above 0.5V offset. There is no example on this...
Posted on March 11, 2014 at 08:52HelloI am trying to configure a timer to get interruption at 12 MHz on the STM32F429 Discovery Kit.I am currently using TIM2 and I cannot reach more than 2.25 MHzTheoritically I could reach 45MHz right?Thank you for ...
Posted on March 11, 2014 at 02:30I plan to make a inverter by using STM32 CPU. STEVAL-ISV003V1 is a good example. But I need to get its firmware.How can I get it? or I can only get it by buying this board?
Posted on March 11, 2014 at 00:54 For my project, I am doing audio mixing from three inputs (pins PC1, PC2, PC4 over Channel 11, 12, 14, respectively) and outputting it the external DAC on the F4-Discovery board. The mixing seems to work properl...
Posted on March 09, 2014 at 20:46Greetings all, I'm new here so I hope I'm doing this right.STM32F0I'm trying to trigger a DMA transfer from TIM2 with CCR1Here's my code for the timer portionTIM_TimeBaseInitTypeDef timerInitStructure;timerInitStruct...
Posted on March 10, 2014 at 11:29Greetings everybody. I'm here to ask you some advice regarding an issue that's troubling me. I'm working with an STM32F103 microcontroller, connected with a Spirit1 radio. What I'm trying to accomplish is a comunicat...
Posted on March 09, 2014 at 20:43Hi,I have downloaded the STM32F4xx_DSP_StdPeriph_Lib_V1.3.0which contains the standart peripherial labrary and examples:Im trying to study GPIO & TIM using this examples....I understand the code and the architecture...
Posted on March 10, 2014 at 02:52 Hi, I'm using the PWM (driven by the DMA controller) to run a line of LEDs. These devices interpret a long high pulse as a start of packet. A pull-down resistor keeps the output in a 'safe' state until the I...
