Posted on January 07, 2013 at 11:09i have designed a little pcb which uses a stm32407vet. i have had 100 boards assembled. and 96 of them work great but 4 of them the gpio on 1 pin (different pin each board) is not working) same firmware on each boa...
Posted on January 07, 2013 at 11:43Hello, I am just trying out the Stop Mode with my STM32L1 Discovery. But I think there is something I do wrong. When I use the HSI as Systemclock the consuption is higher then using the MSI. Also different MSI valu...
Posted on January 05, 2013 at 20:51Hello! I have started doing GUI development on a ARM coretex M3 with 16-bit FSMC and a TFT LCD touch display with a built-in ILI9320 LCD driver. I have used the ST Embedded UI Resource Editor to make some simple sc...
Posted on January 04, 2013 at 18:18HiI'm using STM32F10x_StdPeriph_Lib_V3.5.0 with IAR 6.50 compiler but when I open the workspace in the templade directory and then I build it , I found 240 errors look like these :Building configuration: Project -...
Posted on January 05, 2013 at 01:51 I'm trying to implement PWM on TIM4_CH4 with output on PD15 using only low level register writes as I don't much care for all the high level functions provided. However, I tried to convert the functions to the...
Posted on January 04, 2013 at 09:13I want to use TIM6 and TIM7 together . TIM6- Update Event - 2MHz priority 0x10 TIM7- Update Event - 1MHz priority 0x00 when I closed TIM6 , TIM7 is running normally and toggling LED from PD14 but when I enabled T...
Posted on December 13, 2012 at 05:05I've built a small breakout board for the STM32F373CC:http://ebrombaugh.studionebula.com/embedded/stm32f373breakout/index.htmlI was hoping to be able to use BOOT mode to load it up via the USB device port, but I c...
Posted on January 04, 2013 at 16:58Ok, I'm confused.. according to the docs I should be able to program TIM4 as a PWM with unremaped output on PB9. However, the Timer API call TIM_CtrlPWMOutputs() has an assert which indicates that TIM4 isn't suppo...
Posted on January 02, 2013 at 12:00Hi All,is this normal ? Using 103F along with ST USB CDC Libs on my board and it seems that the USB driver on the PC negotiates a new COM port for every new board i connect to the PC.Normally this is not a problem ...
Posted on January 03, 2013 at 05:56Hi, I have an STM32F4 discovery board and I want to access SD card via SPI. The reason why I want to access Sd card via SPI is that the breakout module that I have has an SPI interface. I have looked on the interne...
