Posted on November 27, 2013 at 22:14Hello, i'm working with a custom board with a STM32L151RD and a st-linkv2. For debugging purpose i only have access to SWD pins:SWCLK (PA14) SWDIO (PA13)TRACESWO (PB3)NRSTBut the microcontroller is JTAG wired by d...
Posted on November 28, 2013 at 18:44I am new to ARM and am trying to create my very first project using an STM32F372CC micro. I have a prototype board connected to a STM32L discovery board. I am using Keil uVision V4.70.0.0. I can compile and downlo...
Posted on November 29, 2013 at 11:53ES0104: STM32F101xC/D/E and STM32F103xC/D/E high-density device limitationsIn CD00197763 �2.13.1 it is statedClear ADDR by reading SR1 register followed by reading SR3SR3? Not SR2? I assume this is an erratum in t...
Posted on November 29, 2013 at 09:46I am using rtc & have 32.768Khz cyrstal oscillator (not resonator). I don't have its datasheet. Neither any marking on oscillator.I have checked AN2867 for capacitor selection i.e CL1 & CL2. But I didn't have data...
Posted on November 27, 2013 at 08:30Hello,I tried to build on Atollic the precompiled package around the emWin graphical lib(AN4323).I build for STM322xG-EVAL, but I get two errors:c:/program files (x86)/atollic/truestudio for arm pro 3.3.0/armtools...
Posted on October 18, 2013 at 04:13Hi, I am makin a encoder interface on the et-arm stamp stm32, my problem is that maximun frequency I can get from the encoder is 30Hz and I just can measure at less 1190Hz (based in PWM_IN example) I am measuring t...
Posted on November 28, 2013 at 14:25Hey everybody,I'm experiencing unexpected behaviour here:1. Debug point before entering GetFlagStatus(): SPI2-> SR = 32. while(SPI_I2S_GetFlagStatus(SPI2, SPI_I2S_FLAG_RXNE) == RESET) {}3. Debug point in GetFlagSt...
Posted on November 26, 2013 at 03:21Hi guys,I'm try to include a set of ASM functions in a project. I have to build this project with arm-none-eabi on a STM32F4-Discovery. My question is how modify the makefile to include the correct building proce...
Posted on November 18, 2013 at 19:21Hello :)I created a working test programm with SPI over DMA with NSS hard. But then the problem is that CS never goes up. So I wan't to choose NSS soft, but then nothing happens on MISO/MOSI/CS/SCK.Is there any op...
Posted on November 26, 2013 at 12:06 Hello, I have a question just for my culture, I have no real error. I send datas via USART3 at the baudrate31250,USART_HardwareFlowControl_None,USART_WordLength_8b. So one USART message t...
