Posted on August 22, 2012 at 17:29In STANDBY mode my board current drops to 300uA which is as expected. However if I use STOP mode it is 880uA. I had expected STOP mode to be only 20 - 30 uA more than STANBY. In STOP mode I turn all pins to analog i...
Posted on December 25, 2012 at 14:43Hello all,I created my own breakout board for the STM32F405RGT6, but I'm unable to connect to it via the ST Link V2. The error is ''No Target Connected''.I've tested this with an external 8Mhz crystal (with load c...
Posted on December 31, 2012 at 19:28Dears, I have problem while debuging the code for STM32L151RDT6. I get every time the hard fault exception with bus fault. Description of Project: I am using KEIL 4.54 with ST Link/V2. The system has SPI FLash (8M...
Posted on December 31, 2012 at 16:49I will use the STM32 to drive a power supply. The input signals to the ADC do not need any gain, so I'd like to avoid using as many OPAmps as possible. The problem is that many of the potentials are negative or ...
Posted on December 29, 2012 at 01:28I've got a mixed-signal board with an LCD connected through noisy SPI lines. When the display is being updated, the analog readings are all over the place. In addition to improving the layout of the board, I'm als...
Posted on December 30, 2012 at 21:28I have been working on a program to directly transmit any character or set of characters that I transmit from the PC via UART, back to the PC immediately. This is just the first step in my project. Code (this work...
Posted on October 11, 2012 at 17:02Hi everyone I did an application board which is containing stm32f405rgt6 but I'm not programming it with stm32f4discovery. I removed the 2 jumpers on cn3 and I did what manifacturer say in ST User Manual UM1457 at ...
Posted on December 29, 2013 at 21:25I'm currently using a ST-LINK/V2 to develop code for STM32F205/7, but am wondering if I would be better off with a Segger J-LINK. What's the difference in capabilities between these two? I using the Atollic IDE/co...
Posted on December 28, 2013 at 14:27I would like to know if there exists a sample code on which I can elaborate to do the following:Transfer data stored in a variable on the microcontroller to computer software such as MATLAB through the USB OTG int...
Posted on December 28, 2013 at 15:22what is the difference betwee TIM2_CH1_ETR and TIM2_ETR? I'v only found TIM2 has the TIM2_CH1_ETR, all other TIMs, such as TIM1, TIM3, TIM8, only have TIMx_ETR. I'v also found the problem that only TIM2 can be tri...
